Approach to Patient with Heart Disease

1- Symptoms of Heart Disease = 2° myocardial ischemia= disturbances of the contraction system / and or relaxation of myocardium

= obstruction of blood flow

= disturbances of the contraction

= abnormal cardiac rate

2- Symptom Relationship to Etiology

- ischemia = manifest as chest pain

- disturbance contraction or relaxation = weakness / fatigue Severe cyanosis, hypotension, syncope, increased intra-vascular pressure

CHEST PAIN

  • Two categories:

  • Recurrent, often paroxysmal pain, which is mild or moderate in intensity.

  • Prolonged & severe pain which is commonly asscoiated with clinical evidence of acute, serious illness.


Clinical cardiology ov erview

(1) Recurrent chest pain:

  • (a) Angina pectoris:

  • Characteristics of anginal pain:

  • It is “visceral” pain: poorly localized and squeezing, oppressive, burning or heavy in quality.

  • Duration: brief, usually it is lasting 2 to 10 min. & it is rarely longer or shorter.

  • Usually it is mild or moderate in intensity.

  • Site: it is typicaly retrosternal, but it may occur in other locations. Even then at least a portion of the pain is commonly beneath the sternum.

  • The pain may be referred to precordium, neck, lower jaws, shoulders, arms, back and epigasterium. Radiation to the left shoulder and arm is especially common.

  • Precipitations: effort or emotional stress, after meals, exposure to cold air or wind.


Clinical cardiology ov erview

  • N.B.: Anginal pain may be excluded under the following circumstances:

    • If it can be localized with one finger.

    • If it consistently last less than 30 sec. or longer than 30 min.

    • If it is sticking, jabbing or throbbing.

    • If it occurs exclusively at rest with twoexceptions:

      • Pre-infarction angina.

      • Variant form of angina, described by prinzmetal, vasospasm of coronaries usually is the leading cause.

    • If the intensity of the pain is consistently severe.


Clinical cardiology ov erview

  • Musculoskeletal chest pain:

  • Characteristics:

  • Radicular in nature.

  • The pain usually occurs at night.

  • It is usually precipitated by fatigue, incorrect posture and movement of the involved segments but not movement of the body as a whole.

  • It may be intensified with coughing or sneezing.

  • The discomfort is usually dull and aching, and may be sharp.

  • The pain usually lasts for hours at time.

  • It is usually relieved by rest, analgesics postural exercises and local heat.


Clinical cardiology ov erview

  • Tioetze’s syndrome:

    - Costochondral and chondrosternal pain, or swelling or both.

    - The pain is usually well localized, but may radiate across the chest and over to the arms.

    -Tenderness on palpation over the involved articulations.

  • Rib pain:may be due to trauma. Rib tumour causes pain if it is metastatic in origin.

    -Pain is usually described as sharp or burning and reproduced by local pressure.

  • Fleeting, jabbing, lancinatingor sticking pains are common in many normal individuals.


Clinical cardiology ov erview

  • The thoracic outlet syndromes(e.g. the scalenus anterior, costoclavicular hyperabduction cervical rib-syndrome), may cause chest pain.

    • Symptoms depend on whether neural or vascular structures are compressed at the thoracic outlet.

      - Nerve compression is the common cause of pain and paresthesia. It may be associated with a demonstrable weakness.

      - Vascular compression is quite rare, as venous obstruction by thrombosis.


Clinical cardiology ov erview

  • Shoulder disorders:

  • May cause pain that is referred to chest.

  • Careful analysis usually reveals that pain is aggravated by shoulder movement, not the body motion.

  • There is local tenderness and pain. Passive movement and limitation of motion are commonly present.

  • Less common causes:herpes zoster and Mondor disease (superficial phlebitis of thoracic wall and chest).


Clinical cardiology ov erview

  • Psychogenic pain :

  • The discomfort of angina may be mimicked by anxiety states.

  • It may take various forms :

    • Intermittent sharp, knifelike pains.

    • Persistent precordial aching unrelated to effort.

    • Tight sensations in chest.

  • It is commonly associated with sighing respiration and symptoms owing to hyperventillation.

  • There is an important statement, that is mentioned by the patient, “ the pain is coming from the heart”


Clinical cardiology ov erview

  • DACOSTA'S SYNDROME:

    - Psychogenic pain usually localized to the cardiac apex. May be associated with anxiety.

    - It May be also associated palpitations, hyperventilation, dyspnea, weakness, depression, or other signs of anxiety.


Clinical cardiology ov erview

  • Pain due to pulmonary hypertension:

    -The cause of pain may be:

    -Right ventricular ischemia

    - Enlarged right ventricle & pulmonary artery may compress on chest &sternum.


Clinical cardiology ov erview

  • Pain associated with valvular diseases:

  • (a) mitral valve prolapse:

  • The pain may be due to :

  • tension on base of the redundant leaflet.

  • Tension on chordae tendinae and papillary muscle.

  • Friction effect of redundant leaflet on myocardium.

  • Associated with syndrome X.

  • Associated with gastrointestinal cause of pain.

  • Coincidental chest pain.


Clinical cardiology ov erview

  • Aortic Regurgitation:

    • The pain usually nocturnal. (Nocturnal Angina).

    • It is termed Angina of Lewis.

    • May be related to baradycardia occurs at night and marked decrease in the diastolic pressure.


Clinical cardiology ov erview

Prolonged chest pain

  • Prolonged, severe, protracted chest pain may be the result of serious underlying disease, such as myocardial infarction, therefore, immediate hospitalization of patients for proper diagnosis and therapy is mandatory.


Clinical cardiology ov erview

  • (a) Acute myocardial infarction:

  • (b) Pain due to Aortic Dissection:

  • (c) Acute pericarditis:

  • Three types of pain may occur in acute pericarditis:

  • Pleuritic pain is the most common type.

  • Steady, severe retrosternal pain of sudden onset, simulating pain of acute myocardial infarction.

  • The rarest type is pain at the cardiac apex felt synchronously with each heart beat.

  • Characteristics:

    • The pain is commonly sharp increased by breathing deeply, swallowing and lying supine. It is sometimes relieved by sitting-up and leaning forward.

    • The pain is most commonly located in the precordial region and may radiate to the neck or left shoulder


Clinical cardiology ov erview

  • Mediastinal Emphysema:

    Free air in the mediastinum produces chest tightness and dyspnea.

    ** Hamman's Sign: Crunching, rasping sound heard synchronous with the heartbeat, indicative of mediastinal emphysema.


Clinical cardiology ov erview

Reminders

  • Angina pectoris: angina is a discomfort in chest or adjacent area that is associated with myocardial ischemia without necrosis. It is due to an imbalance in myocardial oxygen supply and demand.

  • Stable (Typical) Angina: Angina upon effort, or angina induced by increased blood pressure or increased heart-rate. Angina is relieved by nitroglycerin, although nitroglycerin is not specific to this type of angina.


Clinical cardiology ov erview

  • * Levine's Sign: Patient makes fist and holds it up to his chest, to describe the pain.

  • Second-wind Phenomenon: If patient repeats same activity after the attack, he may not feel the attack again the second time.

  • Walk-through Angina: The pain subsides as patient continues the activity.


Clinical cardiology ov erview

  • Atypical Angina: Atypical presentation of typical angina.

  • Atypical Symptoms: Sharp or stabbing pain, rather than crushing pain.

  • Atypical Causes: Angina with change in position, for example, rather than angina strictly upon effort.

  • Angina Equivalents: Other symptoms that are caused by myocardial ischemia.

    > Exertional dyspnea.

    > Nausea, indigestion.

    > Dizziness, sweating.


Clinical cardiology ov erview

  • Unstable Angina: Angina even at rest, or angina that has recently gotten worse. It is associated with sharply increased risk for myocardial infarct within 4 months.

  • Angina Decubitusis a specific term for angina occurring at rest.

  • Variant Angina (Prinzmetal Angina):

    Paradoxic angina occurring during rest but usually not during exercise. It is caused by coronary artery spasm. It can be hard to spot because it can coexist with typical angina.


Clinical cardiology ov erview

  • Clinical presentation of patients with chest pain:

    It can be divided into three subsets:

  • Typical angina pectoris.

  • Atypical angina pectoris.

  • Non-anginal chest pain.


Clinical cardiology ov erview

Dyspnea

  • Definitions :

    It is the patient complaint of:

    - shortness of breath.

    or- he can’t get enough breath.

    or- awareness of respiration.

  • It is subjective distress complaint of difficult breathing.

  • It is one of the most common distressing symptom in cardiovascular disease.


Clinical cardiology ov erview

  • Types:

    - Dyspnea on effort (exertional dyspnea).

    - Orthopnea.

    - Paroxysmal nocturnal dyspnea.

    - Acute pulmonary edema.

    - Cheyne-Stokes Breathing.

    - Dry non-productive cough.


Clinical cardiology ov erview

  • * According to the cause, dyspnea may be:

  • Cardiac causes of dyspnea.

  • Non-cardiac causes of dyspnea.

    Lung diseases.

    Anxiety.

    Anemia.

    Thyrotoxicosis.

    False-dyspneas in:

    Pregnancy  “huff and puff”

    Compansatory hyperpnea associated with metabolic acidosis due to diabetes mellitus and uremia.


Clinical cardiology ov erview

  • Dyspnea on effort:

  • it is a common complaint. It is usually due to congestive heart failure or chronic pulmonary disease.

  • * It is necessary to establish the degree of activity requiring to produce dyspnea.

    - What is about the daily activity of the patient?

    - When the patient began to notice increasing dyspnea?

    *When dyspnea is associated with wheezing:

  • If the patient is an adult especially over 40 years old, heart failure is the foremost in the mind of the physician.

  • If there is a history of periodic wheezing and dyspnea since childhood, bronchial asthma and lung disease is more likely to be the cause of dyspnea.

  • It is important to remember that long standing pulmonary disease may develop heart disease and heart failure. Also heart failure may precipitate more bronchial asthma.


Clinical cardiology ov erview

  • Orthopnea:

    It implies that the patient has more dyspnea when he is lying down.

  • The patient relates that he must use two or three pillows in order to have a restful night.

  • Orthopnea is often associated with congestive heart failure, but may also be associated with severe lung disease. The fatigue associated with the exertion of breathing seems to be less when dyspnea is due to pulmonary disease than when it is due to heart failure.


Clinical cardiology ov erview

Ask the patient:

  • Does the dyspnea occur whether the patient lies on back, left or right side?.

  • Is it improved with digitalis & diuretic?.

  • Does it being within a half minute of lying flat?

  • Is the patient not completely free of dyspnea at any chest elevation (severe mitral stenosis).

  • Is the dyspnea developed rapidly and for less than one minute in supine position and then feels no dyspnea? (suggest pulmonary hypertension).


Clinical cardiology ov erview

(c) paroxysmal Nocturnal Dyspnea:

  • Characteristically, the patient goes to bed and has little difficulty going to sleep in the recumbent position.

  • One or two hours later he is awakened from sleep with acute shortness of breath.

  • He seeks relief by sitting upright, perhaps on the side of the bed, or he even sits in a chair.

  • He occasionally goes to the open window searching for air. After a time he becomes comfortable and returns to bed.

  • He may then sleep comfortably the remainder of the night.


Clinical cardiology ov erview

  •  It is almost specific for left side heart failure.

  •  The only other causes for this unusual sequence of events are:

  • - Hyperventillation syndrome due to anxiety.- Pulmonary emboli.

  • (1) For pulmonary emboli: it would be most unusual for pulmonary emboli to occur for very many nights at the same hour.

  • (2) For hyperventilation syndrome due to anxiety:It is not so clearly relieved by sitting-up and is associated with other signs suggesting this syndrome, such as tingling of arms and hands and other evidence of anxiety.


Clinical cardiology ov erview

  • ASK about:

  • How long after sleeping does it occur? (Redistribution of fluid takes 2-4 hours to raise left atrial pressure).

  • Does the patient angle legs to get relief?.

  • Duration? (10-30 minutes).

  • Is it associated with cough, wheezing or frothy, pink sputum?

  • Obstructive sleep apnea? History of heavy snoring?

  • Paroxysmol nocturnal dyspnea usually occure in patients who are suffering also from exertional dyspnea and orthopnea.

  • The precipitating factors of the attack is uncertain and probably variable. Cough, bad dreams, slipping position, turning to side on which he is ordinary dyspneic and abdominal distension are among those suggested factors.


Clinical cardiology ov erview

  • (d) Acute Pulmonary Edema:

    The patient experiences the sudden development of dyspnea and cough and he may produce frothy blood-tinged sputum.

    This symptom may occur without previous warning as in myocardial infarction, or its may be preceded by cardiac asthma or dyspnea on effort.


Clinical cardiology ov erview

  • (e) Cheyne-Stokes breathing:

    Periods of hyperpnea which alternate with periods of apnea.

    This type of breathing occurs in:

  • Older patients with heart failure, hypertension or cerebrovascular accident

  • It is associated with: Hypoventillation syndrome of obesity (pickwickian syndrome)  the breathing is periodic in nature, but it is not typical as chyne-stoke breathing.

  • Rarely occurs in children or in patients with core pulmonale.


Clinical cardiology ov erview

  • (f) Dry non-productive cough:

  • Cough may on occasion the earliest symptom, the most prominent symptom or the only apparent symptom of left ventricular failure.

  • * Cough is an important symptom in certain forms of cardiovascular diseases, even in absence of heart failure :

  • Aortic aneurysm with compression on bronchus or trachea.

  • Mitral stenosis with aneurysmally dilated left atrium.

  • Markedly dilated pulmonary artery.

  • Congenital double aortic arch forming a vascular compression ring around the trachea.


Clinical cardiology ov erview

  • Trepopnea:

    Dyspnea that occurs in only one of several recombent positions not due to congestive heart failure:

    (a) Cardiomegally.

    (b) Musculoskeletal.


Clinical cardiology ov erview

  • Platypnea:

    It is the dyspnea provoked by sitting-up.

  • Left atrial myxoma.

  • Ball-valve thrombus of left atrium.

  • Orthostatic hypotension.

  • N.B.:

  • Some patient with angina pectoris, may complaint of dyspnea rather than chest pain. This is termed (Angina equavelent).


Clinical cardiology ov erview

  • Clinical significance of orthopnea:

  • It is usually the result of heart disease (as many as 95% cases). It reflects, a severe lung congestion on lying supine in patients with left sided heart disease.

  • In about 5% of causes, are related to lung diseases:

  • Chronic obstructive lung disease (COLD) with apical bullae, where the sitting position, not only improves the gas exchange but also, lung mechanics.

  • N.B.:

  • patients with COLD, usually have a sitting-up and either clasping the side of the bed or pushing over their thighs, producing the formation of two patches of hyperpigmented callus immediately above the knees (Dahl’s sign.).

  • Orthopnea in asthmatic patient is usually a sign of severity. If it is observed at time of emergency, it is a good predictor of poor outcome.


Clinical cardiology ov erview

Paroxysmal Nocturnal dyspnea (PND).

  • It is sought to be specific for Left sided heart disease and failure, but:

  • Patient with chronic obstructive lung disease (COLD) may have PND due to excessive secretion upon lying down.

  • Asthmatic patients also may have PND due to night worsening bronchospasm.

    Orthopnea:

  • Occurs in patients with heart failure, but also may occur in patients with COLD due to partial loss of diaphragmatic and accessory muscle function when supine.


Clinical cardiology ov erview

Palpitation

  • It is a disagreable awarness of the heart beat. The patient may use some other terms and report as “pounding”, ‘stopping”, “jumping”, or “racing” in the chest. The patient may complain when the heart beat is slow, fast or irregular.


Clinical cardiology ov erview

  • If there is a history of palpitations:

  • (a) Orientation:

  • When did they begin?

  • Ask about: shortest, and longest duration and the length of time between attacks.

  • (b) Types and rate: ask about.

  • Regular or irregular.

  • Sustained or occasionally, strong beats.

  • Onset and offset.

  •  gradual  sinus tachycardia.

  •  sudden  ectopic tachycardia.

  • Rest or exercise.

  • Associated symptoms.

  • Maneuvers or medications that stop it.


Clinical cardiology ov erview

Hemoptysis

  • Definition :

  • It means coughing-up blood.

  • Brisk bleeding: is commonly associated with specific focal ulceration of the bronchus, such as” (bronchogenic carcinoma, foreign body, or bronchiectasis).

  • Slow bleeding: Strongly suggest venous bleeding and is more likely to be the result of increased pulmonary vascular resistance, with secondary increase in flow through the bronchial venous system such as may occur as a result of mitral stenosis or bronchiectasis.

  • It is also helpful to notice whether the expectorated blood is admixed with sputum or pus. This is valuable, as the site of origin of the bleeding could be determined. Intimate admixture of blood and pus are signs pointing to a deep-seated site of pulmonary suppuration such as pyogenic lung abscess.


Clinical cardiology ov erview

  • Three conditions must never be overlooked as causes of hemoptysis:

  • (1) Mitral stenosis:

  • It is frequently induced by physical exercise, sexual intercourse, or marked excitement.

  • It may be the first symptom, and may occur during pregnancy.

  • The blood comes from a break in the pulmonary veins, which rupture under high pressure.

  • Apoplexy: occurs in 10% of cases with reversible pulmonary hypertension due to rupture of broncho-pulmonary venous varicosities. This type tend to subside as the vein adapt to high pressure and as pulmonary arteriolar disease develops.


Clinical cardiology ov erview

  • 2) Pulmonary infarction:

  • Frank hemoptysis occurs in the minority of instances.

  • When hemoptysis occurs in a patient with heart failure, pulmonary infarction is likely.

  • The bloody sputum usually appears from a few hours to a day after the embolus.


Clinical cardiology ov erview

  • (3) Eisenmenger physiology:

    Patients with severe pulmonary hypertension associated with atrial septal defect, or patent ductus arteriosus, may have hemoptysis, secondary to rupture of pulmonary capillaries.

  • Four additional rare causes of hemoptysis:

  • Rupture of a pulmonary arteriovenous fistula.

  • Rupture of aortic aneurysm into the trachea or bronchus.

  • Pulmonary hemosiderosis.

  • Bronchial ulceration due to foreign body.


Clinical cardiology ov erview

Cyanosis

  • Definition :

  • Bluish coloration of skin and mucous membrane.

  • Cyanosis cannot occur when the hemoglobin is less than 33 percent of normal since reduced hemoglobin cannot be produced in an amount sufficient to cause the bluish color (Five grams of reduced hemoglobin is needed for cyanosis to occur). When the hemoglobin is normal, about one-third of it must be in the reduced form for the bluish color to appear.


Clinical cardiology ov erview

* Clinical significance of history of cyanosis:

  • If cyanosis is present only during the neonatal period the possibility of an atrial septal defect with temporarily reversed flow (right-to-left shunt) during the neonatal period is suggested.

    • However, the most common causes of neonatal cyanosis are, atelectasis, pneumonia, or even occasionally from cerebral damage.


Clinical cardiology ov erview

  • Persistent and severe neonatal cyanosis suggests a right-to-left shunt often with marked impairment of pulmonary blood flow:

  • Tetralogy of Fallot with pulmonary atresia.

  • The hypoplastic left ventricular syndrome.

  • Tricuspid atresia.

  • Sometimes transposition of great vessels.


Clinical cardiology ov erview

  • Cyanosis that develops after a few years of life suggests a less severe form of tetralogy of Fallot, in about of 75% or more. Cyanosis often appeas following delayed closure of a patent ductus arteriosus, or when child begins to walk.

  • Cyanosis occuring later in life of childhood is suggestive of Eisenmenger complex (N.B. Occasionally cyanosis may be present early in life with this disorder, but not common).

  • Patients with trialogy of Fallot (atrial septal defect and pulmonary stenosis), usually describe history of cyanosis, late in (childhood or adolescence).


Clinical cardiology ov erview

  • A history of squatting with severe cyanosis (Hypoxic spells), are most suggestive of:

    • Tetralogy of Fallot.

    • Trialogy of Fallot.

      - tricuspid atresia.

  • N.B.

    • Squatting seldom occur in Eisenmenger syndrome.

    • The squatting usually occur to relieve dyspnea and spells of unconsciousness, with severe cyanosis.

  • In adults cyanosis and digital clubbing may be caused by right-to-left- shunting. Such shunting is most often the result of the Eisenmenger syndrome and occasionally of tetralogy or trialogy of fallot or Ebstein’s anomally, or partial transposition of the great vessels.

  • Adult cyanosis also may result from chronic or acute pulmonary disease.


Clinical cardiology ov erview

  • Adult cyanosis also may result from chronic or acute pulmonary disease.

  • Chronic disease as:

  • Chronic obstructive lung disease.

  • Hypoventillation syndromes.

  • Pulmonary infiltrative diseases as Hamman-Rich syndrome, sarcoidosis, metastatic cancer or severe bronchiectasis.

  • Acute disease:

     Pneumonia.

     Pulmonary embolism.

     But the patient seldom complains of cyanosis in these problems.


Clinical cardiology ov erview

  • Cyanosis due to stagnant hypoxia:

  • Distal parts of extremities usually cyanosed in advanced heart failure.

  • Cyanotic hands may be due to local stagnation called (Acrocyanosis).

  • Rarely, cyanosis is caused by chronic or acute methemoglobinemia, or apparent cyanosis by argyria, which causes a bluish-gray discoloration of the nail beds and mucosae associated with prolonged use of nose drops containing silver.

  • Acute cyanosis in patients with chronic heart failure, should suggest the possibility of associated pulmonary embolism.


Clinical cardiology ov erview

  • Very specific physiologic implication can be made when differential cyanosis is found:

  • (1) Cyanosis of the fingers greater than that of the toes suggests complete transposition of great vessels with either a preductal coarctation or complete interruption of aortic arch and pulmonary hypertension with reversed shunt through a patent ductus arteriosus delivering oxygenated blood to the lower extremities.


Clinical cardiology ov erview

  • N.B. If the left arm is slightly less cyanotic than right arm, the coarctation of aorta is suggested. On the other hand if both arms are intensely cyanosed, complete aortic interruption is suggested.

    (2) Cyanosis and clubbing of the toes associated with pink finger nails of right hand and minimal cyanosis and clubbing of left hand are suggestive of pulmonary hypertension with reversed shunt through patent ductus arteriosus with normally related great vessels.

    (3) If the right hand is pink and the left hand and lower extremities are intensely cyanosed, this suggest, that the right subclavian artery arises proximal to aortic obstruction, plus patent ductus arteriosus and pulmonary hypertension.

    On the other hand, if the right subclavian artery originates anomalously from the descending aorta, then both hands are cyanotic.


Clinical cardiology ov erview

Syncope

  • Definition:

  • It is a complete and transient loss of consciousness due to inadequate cerebral blood flow. The physician should bear in mind that the commonest variety of syncope (vasodepressor syncope) is not caused by organic heart disease, or by organic disease of the circulation.


Clinical cardiology ov erview

  • Clinical significance:

    Syncopethat occurs in a threatening situation, such as venipuncture suggests simple vasodepressor syncope.

    A history of syncope since childhood when associated with organic heart disease, may suggest the possibility of congenital aortic stenosis.

    Syncopal spells occur with tetralogy of Fallot, in such a case, it is associated with dyspnea & cyanosis.


Clinical cardiology ov erview

  • In children syncope rarely occurs in primary pulmonary hypertension.

  • Syncope seldom occurs in congenital complete atrioventricular (AV) block since the heart rate is usually greater than 55/min. and the cardiac output reasonably well maintained.

  • In older patients a history of syncope may be related to one of several variaties of organic heart diseases:

  • If the patient is thought to have mitral stenosis, a history of syncope may be very significant, it seldom occurs with uncomplicated mitral stenosis. Such a history suggests the possibility of a left atrial myxoma, or ball-valve thrombus with intermittent obstruction to left ventricular filling.


Clinical cardiology ov erview

  • Syncope in patient with ESM & LVH :

    • If typically occurs with exercise suggests aortic stelosis.

    • If it occurs after stopping exercise suggests HOCM.

  • A history of syncope in patient with angina should raise the possibility of aortic valvular stenosis.

  • Syncope rarely occurs in patient with ischemic heart disease, although occasionally it occurs at the outset of acute myocardial infarction.

  • Syncope may occur in patients who have paroxysmal tachycardia.

  • Syncope may be the initial symptom of massive pulmonary embolism.

  • Syncope that occurs while shaving or while suddenly turning the head, especially when wearing a tight collar, suggests carotid sinus syncope.


Clinical cardiology ov erview

  • It is important to have a history of the position in which syncope occurs. The patient may become light-headed or giddy when first arising in the morning and becomes more able to tolerate the upright posture during the day. This history suggests orthostatic hypotension.

  • Syncope, which is associated with memory defects, temporary hemiparesis, paraplegia, vertigo or tinuitus in an older patient suggests that vertebrobasilar artery insufficiency may be responsible.


Clinical cardiology ov erview

  • It is a heterogeneous symptom, including sensations of vertigo, presyncope, disequilibrium and light-headedness.

  • It is one of the most complaint in general medical clinics. It is often self-limiting and only rarely relates to life-threatening events, even in elderly patients.


Clinical cardiology ov erview

*Common causes include:

  • Peripheral vestibular vertigo, labyrinthitis, Meniere’s disease

  • Central vestibular cerbellovascular tumor.

  • Psychiatric disorders and hyperventilation usually in younger patients.

  • Multicausal.

  • ** Blurring of vision and even petit mal epilepsy may be revered as dizzy spells


Clinical cardiology ov erview

  • Giddiness:

  • blurring of vision associated with altered consciousness and swaying sensation.

  • Vertigo:

  • Literally it means “sense of turning”  “rotation” either of the one’s body or of the surroundings.

  • ** The history is an easy pointer to vertigo:

  • Patient reports objects in his environment spun around

  • Or his body was turning.

  • Or his head was spinning.

  • Sometimes he may state that the floor or walls seemed to undulate or sank or rose-up toward him or he was feeling of to and fro or up-and down movement of the body, usually head.

  • The symptoms of vertigo are usually paroxysmal and of short duration but may be chronic following acute attack.

  • It is accompanied by varying degrees of nausea and vomiting, nystagmus headache and ataxia, as well as by the need to avoid movement of the head.


Clinical cardiology ov erview

Edema

  • Definition:

    It is an increase in the volume of interstitial fluid (i.e., the extravascular portion of the extracellular compartment). The plasma volume may or may not be increased.

    ** Interstitial fluid volume may increase considerably before it is clinically appreciated.

    ** Edema is considered a symptom and a sign.


Clinical cardiology ov erview

  • It is important to ascertain whether edema of the extremities preceded or followed dyspnea on effort. Edema of cardiac origin is usually preceded by dyspnea, and usually associated with dyspnea except with tricuspid stenosis.


Clinical cardiology ov erview

  • Edema of one leg:

  • - Varicose veins.

  • - Thrombophlebitis.

  • - Lymphedema.


Clinical cardiology ov erview

  • Periorbital edema:

  • It is common in children than adult.

  • It is common due to renal causes, but may occur in heart failure.

  • ** Rare causes of periorbital edema: (superior vena caval obstruction, and trichinosis).


Clinical cardiology ov erview

Ascitis:

  • It is recognized by the patient as an increase in girth or swelling of the abdomen.

  • Ascitis due to heart failure is uncommon to day and usually follows peripheral edema.

  • A local factor such as cirrhosis is also suggested when ascitis associated with heart failure, seem to be out of proportion to peripheral edema.

  • Constrictive pericarditis and endomyocardial fibrosis are rare causes of cardiac causes of ascitis.


Clinical cardiology ov erview

  • In children:

  • Hepatomegally and ascitis are the first symptoms & sign of cardiac edema than peripheral edema due to:

  • Portal circulation of children is less complaint.

  • Systemic circulation in children is more complaint.


Clinical cardiology ov erview

  • Edema is a symptom and also it is a sign.

  • On examination it can be elicited as follows:

  • Press on the skin over a bony area with 3 fingers spread apart for 10-30 seconds.

  • Feel and look of at the valleys produced.

  • It is of two types.

  • Slow edema: the pitting remains for more than 60 seconds, and it is usually due to congestion.

  • Fast edema: the pitting remains less than 40 seconds, and it is usually due to hypoalbuminemia.


Clinical cardiology ov erview

  • Fatigue

  • Definition:

  • It is a sense of weakness, described by the patients variously as exhuastion, tiredness, lack of interest, low vitality or a feeling of being “all in”.

  • It is often accompanied by a subjective sensation of weakness and a strong desire to rest and sleep.

  • When a patient with heart disease is water-logged or when there is pulmonary congestion due to heart disease, the patient is likely to complain of dyspnea.

Clubbing and cyanosis:

These are typical of congenital heart disease or pulmonary arteriovenous fistula with a right to left shunt.

  • Differential cyanosis and clubbing:

    It has a specific physiologic implication:

  • Cyanosis of fingers is greater than that of the toes; suggests transposition of great vessels with either a preductal coarctation or complete aortic arch interruption with pulmonary hypertension, and reversed shunt.

  • In this case, if the left arm is less cyanotic than right, coarctation of aorta is suggested.

  • On the other hand, if the cyanosis is intense and symmetrically, aortic arch interruption is suggested.


Clinical cardiology ov erview

  • Cyanosis and clubbing of the toes, associated pink fingernails of right hand and minimal cyanosis of left hand: this suggests patent ductus arteriosus with normally related vessels and pulmonary hypertension with reversed shunt.

  • Cyanosis & clubbing of the toes and left hand while the right hand is not cyonatic, this suggests, the right subclavian artery arises proximal to coarctation of aorta.


Clinical cardiology ov erview

  • Reversed differential cyanosis:

  • Hands are cyanotic and clubbed, but the feet are normal.

  • This occurs when there is right ventricular origin of both great vessels, with concomitant disorder including VSD, PDA & pulmonary hypertension  oxygenated blood from LV enters the pulmonary trunk through VSD, or from PDA into descending aorta so the feet are normal. While the oxygen-desatrurated blood from RV enters the ascending aorta and brachiocephalic vessels so the upper extremities are cyanosed and clubbed.

** Taking of the Pulse

It is important to turn the patientshand palm side up fortaking the pulse, or else the exainer will not be able toview what it is you are doing.

@Assess the Rate: Normal is 60 - 100 beats per minute.

Bradycardia is < 60 and Tachycardia is >100.

Assess the Rhythm:

(i) Regular (consistent predictable

beat),


Clinical cardiology ov erview

  • (ii) Irregularly irregular (inconsistent unpredictablebeat which occurs in atrial fibrillation), and (iii) Regularly irregular (inconsistent but predictable pattern to the beat – which occurs in Second Degree Mobitz Type I (Wenckebach)

  • Heart Block which is increasingly prolonged PR intervals(on ECG) followed by a dropped QRS at which point the PRshortens and then lengthens progressively again until QRS isdropped again, and so on)

or Sinus arrhythmia which is increased pulse on inspiration due to increased venous return,and decreased pulse on expiration (it is normal).


Clinical cardiology ov erview

@Assess the characterof the pulse: Note that the character of

the pulse is poorly assessed by the radial pulse.

Rather, the carotid or brachial pulse should be used to assess the brachial pulse.

Water Hammer Pulse: this is checked by raising the


Clinical cardiology ov erview

  • patients arms while assessing the pulse.

  • The pulsebolus can be felt to fall back towards the patient and this is significant of Aortic Regurgitation (you are in effect creating a hydrostatic pressureincrease into the valve by raising the arm and so the pulse which is a blood ejection bolus impinges onthe incompetent valve)


Clinical cardiology ov erview

(ii) Slow Rising Plateau Pulse: This is a

pulse that has a slow rising bolus under your finger, but thenthe bolus itself lasts for a long time before it slowly comes down.

It can be likened to feeling a long worm sliding past your finger as you feel the pulse.

This signifies aortic stenosis.

(iii) Pulsus Alterans: This is a pulse that is strong

one minute,then weak the next. This signifies Left

Ventricular Failure.


Clinical cardiology ov erview

@Assess the volume of the pulse:

> The volume is increased in aortic

regurgitation, and decreased in aortic stenosis.

It can be best described as the loudness of the pulse

under your finger.

> And it is a qualitative measure of the pulse pressure.

Since in aortic regurgitation the diastolic pressure is so low

(as blood slips back into the left ventricle from the

aorta), then the ejection of the over-filled ventricular

blood in systole will causea dramatic increase

in pressure.

>This will feel like a loud pulse under the examiners fingers.

  • @Assess Radio-Radial Delay:

  • Feel for the radial pulses in both arms simultaneously. If any delay is detected, this may signify

    a large arterial occlusion by large atherosclerotic plaque or aneurysmal process

  • Look at the Tongue and Lips for central cyanosis (defined as > or equal to 5mg/dl

    of deoxyhemoglobin in the blood.

(7) Examination of the Neck:

Carotid Arteries

Inspect the neck area for carotid

endarterectomy scars

Palpate the carotid arteries.

NEVER palpate both carotids simultaneously,

you may occlude the

majority of the cerebral perfusion and thus

cause your patient to faint

....and a big fat fail to ensue as your exam mark.

Palpate for the character of the pulse which

can be as follows:


Clinical cardiology ov erview

Also, on palpating the carotid artery, it is important to evaluate the presence of systolic thrill, that may be produced by:

-Carotid atherosclerosis.

-Kinking of carotid arteries.

-Valvular aortic stenosis.

-Carotid shudders in severe aortic regurgitation.


Clinical cardiology ov erview

* Anacrotic -means small volume, slow uptake,notched wave on upstroke indicative of aortic stenosis.

* Plateau - means a prolonged but diminished upstroke, is also indicative of aortic stenosis.

* Biferiens - is the term used for anacrotic and collapsing pulse which occurs when the patient has both aortic stenosis and regurgitation simultaneously.

  • * Alterans - strong and weak beats interchanging irregularly - indicative of Left Ventricular Failure

  • * Jerky pulse - strong and spike of a pulse wave - indicative of Hypertrophic Cardiomyopathy.

Abnormalities of Arterial Pulse:

I.General Abnormalities:

The size of the arterial pulse is determined by:

-Left ventricular stroke volume.

-Rate of ejection.

-Distensibility of the systemic arterial bed.

-Peripheral resistance.

-Systolic and diastolic pressures.

-The distance between the heart and the palpated artery.


Clinical cardiology ov erview

* There are two clinical abnormalities of the pulse size:

a)Hypokinetic  Small, weak pulse.

b)Hyperkinetic large, strong pulse.

So on palpation of an artery, one should obtain an impression of both the height of pulse pressure and the rate of pressure pulse change.


Clinical cardiology ov erview

  • Hypokinetic Pulse

  • Weak and small pulse

  • Occurs in conditions with:

  • Low stroke volume of left ventricle

  • A narrow pulse pressure.

  • Increased peripheral vascular resistance.


Clinical cardiology ov erview

  • Common causes:

    • Left ventricular failure.

    • Constrictive pericarditis and tamponade.

    • Valvular stenosis (aortic, mitral, tricuspid or pulmonary)

      - Shock, tachycardia...).


Clinical cardiology ov erview

  • Hyperkinetic Pulse

  • The pulse pressure shows a rapid rates of rise.

  • It may be

  • a)Rapid rates of rise with normal size:

  • This is termed: (Jerky or Brisky Pulse).

  • Occurs in:


Clinical cardiology ov erview

  • Double way of left ventricular ejection, as in:

    • Mitral regurgitation.

    • Ventricular septal defect (VSD).

  • Hypertrophic obstructive cardiomyopathy (HOCM): where there is no obstruction until the outflow tract contracts and approximates the thickened septum to mitral valve. The hypertrophied muscles of LV ejects about 80% of blood before obstruction.


Clinical cardiology ov erview

b) Pulse of rapid rate rise with increased pulse pressure.

1-Bounding pulse: rapid rates of rise with increased pulse pressure, but with normal contour.

2- Collapsing or water hummer pulse, sometimes termed Corrigan’s pulse: Exaggeration of bounding pulse, where there is a short and sharp peak, with contour change, as the wave is transmitted peripherally.

The rapid upstroke and downstroke tend to be exaggerated as the pulse wave is transmitted peripherally. So these abnormalities are often better appreciated by palpating the brachial and radial arteries than palpating carotid arteries


Clinical cardiology ov erview

  • Hyperkinetic pulse is usually associated with:

  • Increased stroke volume of left ventricle

  • Wide pulse pressure.

  • Decrease in peripheral resistance.

  • Hyperkinetic circulatory states, may be considered in three main categories:


Clinical cardiology ov erview

  • 1- Hyperkinetic states with NORMAL hearts:

  • Fever.

  • Pregnant females secondary to arteriovenous shunt in the placenta

  • Hyperthyrodism, anemia..., etc


Clinical cardiology ov erview

2- Hyperkinetic states due to abnormally rapid run-off of blood from arterial system:

-Shunting of blood from aorta: (patent ductus arteriosus, aortopulmonary septal defect, rupture of a sinus of valsalva into the right atrium or right ventricle).

- Large peripheral arterio-venous fistula: (Congenital, traumatic, mycotic  etc).


Clinical cardiology ov erview

- Small multiple arterio-venous fistula: (Pajet’s disease of bone, cirrhosis of the liver).

- Aortic regurgitation  moderate to severe.

- Occasionally severe mitral regurgitation.

3) Complete Heart Block with bradycardia,  increased strok volume.


Clinical cardiology ov erview

(II) Specific abnormalities:

A) Pulsus Parvus et Tardus:

It describes a small pulse with a delayed systolic peak.

- This pulse has a delayed peak, so it is termed (plateau) pulse.

- When the aortic stenosis is severe the anacrotic notch is easily observed in the ascending limb, so it is also termed (anacrotic) pulse.

- This type of pulse is characteristic of aortic stenosis of at least moderate severity.


Clinical cardiology ov erview

N.B.

Systolic thrill is usually palpated over carotids & usually occurs between anacrotic notch and the peak.

The character of this pulse may be disappeared in patients with left ventricular failure, and in patients with concomitent mitral stenosis.

Some elderly patients with calcific aortic stenosis may have nearly normal carotid pulse inspite of severe obstruction due to rigid aorta, as a result of atherosclerotic changes, so the aorta is unable to expand.


Clinical cardiology ov erview

In supravalvular aortic stenosis, also the patient has a plateau pulse, but can be differentiated by:

Difference in pulse volume between both arms.

Right sided carotid thrill.

Blood pressure is higher in the right arm than the left.

Characteristic facies (Elfen Face).


Clinical cardiology ov erview

B) Double Beat = Twice -beating pulse:

This term is applied when two waves are palpated during each cardiac cycle. The second wave may be palpated either during systole or diastole.

Dicrotic Pulse.

The Second wave is palpated during diastole.

It is produced by accentuation and palpable dicrotic wave following the second heart sound.

Palpated in both carotid and peripheral arteries.


Clinical cardiology ov erview

The dicrotic wave becomes palpable when there are:

Low cardiac output.

Soft and elastic aorta.

High peripheral resistance


Clinical cardiology ov erview

The most common causes of palpable dicrotic wave are:

Severe congestive heart failure as in (DCM).

Tamponade.

The low output state following open heart surgery, especially aortic valve replacement.

Fever.(typhoid fever)

Anacrotic Pulse:

Exaggeration of anacrotic notch gives palpable two wave during systole as in aortic stenosis (Severe).

Pulsus Bisferiens: Bis = twice & feriens = beating:

Causes and Mechanisms

HOCM:

> Upstroke or ascending limb  rises initially very rapidly and forcefully. (an initial systolic wave  (Percussion Wave).


Clinical cardiology ov erview

> Systolic dip: due to sudden decrease in the rate of left ventricular ejection, as the obstruction becomes significant.

> Tidal wave:  Follows the systolic dip, and produced by continued but slower decelerated ventricular ejection, and reflected wave from periphery.

> The percussion wave is usually higher than the tidal wave.


Clinical cardiology ov erview

Significance:

It is characteristic of Hypertrophic obstructive cardiomyopathy and it may be the first clinical clue of HOCM.

It may be possible to bring out the characteristic bisferiens pulse by performing valsalva maneuver or by exercise.

In combined Aortic stenosis (AS) and Aortic regurgitation (AR)

The aortic regurgitation should be at least of moderate severity.


Clinical cardiology ov erview

The bisferiens pulse may be palpated in pure Aortic Regurgitation which should be severe.

Also bernouli effect is the underlying mechanism.

** There is an important feature that can differentiate the bisferiens pulse in HOCM from other causes of pulsus bisfierience; which is the character of pulse following extrasystoles:


Clinical cardiology ov erview

- In HOCM, the pulse is very small following extrasystoles, where more contraction causes more obstruction.

- In other causes, in normal the pulse wave is strong after extrasystole (post-extrasystolic potentiation) =(pulse is exaggerated than normal).


Clinical cardiology ov erview

Pulsus Alternans

There is a regular alternation of the height of the pressure pulses, but the beats occur at a regular intervals.

Frequently, may be more readily detected while taking the arm blood pressure.

There is alternation of left ventricular contractile force.

Alternation of LV end-diastolic volume and stroke volume.

Sometimes alternation of LV end-diastolic pressure

** mechanisms

Sudden critical change in diastolic filling period.

Alternation in the number of cardiac fibres contributing to each systole.


Clinical cardiology ov erview

Significance:

- May be associated with third heart sound (S3)

- May be observed after premature ventricular contraction or tachycardia in heart failure without pulsus alternans.

- Latent pulsus alternans: in some patient with heart failure, without apparent pulsus alternans, the characteristic pulse can be exaggerated by:

> Upright position.

> Nitroglycerine therapy.

> Exercise.


Clinical cardiology ov erview

D) Pulsus Bigeminus:

It is the most common cause of peripheral arterial pulsations that alternate in size from beat to beat:

The strong pulsation occurs after long diastolic filling phase following the premature beat.

The weak pulse occurs due to weak premature beat.

Significance:

It is commonly associated with digitalis toxicity.


Clinical cardiology ov erview

E) Pulsus paradoxus:

Normally the systolic blood pressure usually declines (5-10 mm.Hg) during inspiration.

** Best observed by careful measurement of blood pressure.


Clinical cardiology ov erview

** It is due to relative pooling of blood in the pulmonary vasculature during inspiration, as a result of lung expansion and of the more negative intrathoracic pressure. In addition transmission of the negative intrathoracic pressure to aorta and great vessels.

** So pulsus paradoxus is exaggeration of the normal: the declines in the systolic pressure during inspiration is more than 10 mm.Hg.


Clinical cardiology ov erview

Significance:

*Pulsus paradoxus may be produced by conditions which:

- Limit the inspiratory increase in blood flow to right ventricle and pulmonary artery.

- Cause a greater than normal amount of inspiratory pooling of blood in the lungs.

- Cause the intrathoracic pressure to have very wide extremes of pressure during inspiration and expiration.

- Interfere with venous return to either atrium relatively more during inspiration, e.g abnormal inspiratory increase in pericardial pressure.


Clinical cardiology ov erview

**Several clinical conditions are associated with pulsus paradoxus:

> Superior vena cava obstruction.

> Asthma, emphysema and airway obstruction.

> Pulmonary embolism.

> Severe heart failure

> Cardiac tamponade due to pericardial effusion.

> Constrictive pericarditis.

> May occur in patients with severe hypotension  shock.


Clinical cardiology ov erview

N.B: Patients with cardiac tamponade

- have pulsus paradoxus.

- Also may have kussmaul’s sign (a truly paradoxic finding), which is an increase in peripheral venous distension during inspiration.

Mechanism: change in the pericardial shape  rises the intrapericardial pressure  obstructs venous return to the heart.


Clinical cardiology ov erview

In contrast to this the pulsus paradoxus that occurs with pulmonary diseases (asthma, emphysema... etc) have marked exaggeration of the normal expiratory increase in venous pressure.

*So this is of great diagnostic importance that differentiate pulsus paradoxus in patient with pericardial diseases from that in patients with pulmonary disease

Blood Pressure Measurement:

=First make sure that the blood pressure cuff you are

utilising is the right size for the patient (this is done

by placing the width of the cuff around the arm

, for it to be accurate, the width of the cuff needs to be

approximately of the circumference of the arm.

This is significant because a cuff that is too large for

the patient over estimates blood pressure and a cuff

that is too small for the patient under

estimates the blood pressure.

=Sit the patient down or keep them lying in the bed but sit

them up at 45 degree angle.


Clinical cardiology ov erview

* Too-narrow and too-large cuff:

* A too-narrow cuff may give false higher reading in systolic pressure up-to 50 mmHg, due to higher inflation pressure is needed to inflate the cuff.

* A too- large cuff may give false low blood pressure.

* On begining deflation of cuff the release should be slowly to avoid spasm of artery at the begining.


Clinical cardiology ov erview

=First find the systolic pressure by inflating the cuff while feeling for the radial pulse. (Do not use the

stethoscope yet). The pressure at which the pulse

first disappears is the systolic pressure. This is done

first because it allows you to estimated what range

you; d expect the systolic pressure to be in this

patientbefore commencing auscultation.

=Deflate the cuff.

.. Nowposition the stethoscope over the brachial

artery, and inflate the cuff again until the

pulse sounds are no longer heard.


Clinical cardiology ov erview

..Now deflate the cuff at about

3-4mmHg per second until

the first pulsation is heard again

(this is the first Karatkoff sound).

..Continue to deflate the cuff until

absolutely no more sounds

are heard anymore (the very last

turbulent sound will

be that of the 5th Karatkoff sound).

=Repeat the process in the other arm.

Note that the BP can


Clinical cardiology ov erview

vary between arms by up to 10mmHg and still

be normal.

=Now Repeat the Blood Pressure in the patient

while theyare standing. If systolic blood pressure

falls by >15mmHg or diastolic pressure falls

>10mmHg then one can pronouncethe patient

has postural hypotension (the gold standard test is

the Tilt Table Test where the BP and ECG is

taken at 3 minute intervals while the patient is

Tilted in a special table from the horizontal position

To the vertical in increments of 15 degrees


Clinical cardiology ov erview

* Auscultatory gap:

> It is the silence caused by the disappearance of korotkoff sounds after the first appearance of the true systolic pressure, and reappearance of pressure (some 10-20 mm.Hg lower ).

> It requires venous distension of the forearm and concomitant low flow.

-To avoid it:

Determine the systolic blood pressure first by palpitory method.

Routinely ask the patient to clench his first 10 times and inflate the cuff rapidly.


Clinical cardiology ov erview

* Pseudo-hypertension:

> Misleadingly high systolic, diastolic or mean blood pressure measured by cuff compared with the pressure measured directly by intra arterial needle.

> Observed in medial necrosis of brachial artery (Monckeberg arteriosclerosis).

--- Pipesteam calcified brachial artery.


Clinical cardiology ov erview

* Pseudohypertension is suspected in elderly:

> Disproportionate elevation of blood pressure to clinical findings: (no ECG. evidence of LVH, no cardiomegaly in X-ray).

> A palpable radial pulse after the brachial pulse has been eliminated by inflation of the cuff above systolic pressure. (Osler’s sign maneuver)


Clinical cardiology ov erview

  • Subclavian Steal:

    > the use of a vertebral artery as a collateral circulation to feed the subclavian artery (usually on the left).

    > Blood from a vertebral artery flows retrogradely into the distal subclavian, thus “stealing” blood from the brain causes vertibro-basilar insufficiency and the blood pressure is lower in one arm than other.


Clinical cardiology ov erview

Pulse pressure:

It is the difference between systolic and diastolic blood pressure: ( thus in patient with systolic blood pressure of 120 mmHg, and diastolic blood pressure of 80 mmHg, the pulse pressure is 40 mmHg ).


Clinical cardiology ov erview

-Abnormally narrowed pulse pressure:

The pulse is considered abnormally narrowed if it is less than 25% of the systolic value. (For example, a patient with systolic blood pressure of 100 mmHg and diastolic pressure of 90 mmHg has a pulse pressure of 10 mmHg (


Clinical cardiology ov erview

Causes:

a- The most common cause is a drop in left ventricular stroke volume, as in patients with obstruction to left ventricular filling or left ventricular emptying (e.g.: tamponade, constrictive pericarditis or aortic stenosis(.

b- It may be observed in extreme tachycardia, in which the filling time of ventricle is reduced.

c- It may be seen in shock as a result of increased peripheral resistance.


Clinical cardiology ov erview

-* Reversed pulsus paradoxus:

> It is an increase in systolic blood pressure that coincides with inspiration rather than expiration.

> Itis observed in :

1- Hypertrophic cardiomyopthy: it is a typical sign due to (stiff septum) & reversed inspiratory movement.

2- Some cases of severe left ventricular failure (stiff & less compliant ventricle).

3- Positive-pressure ventilation reverses the respiratory changes in intra- thoracic pressure.

Neck Vein

The bedside examination of the pulsations in the neck veins is the clinical key to the dynamics of the right side of the heart.

Two main objectives should be observed:

> Study of the wave form of pulsations.

> Venous pressure.


Clinical cardiology ov erview

* Principles of studying the Neck Veins:

1- It is necessary to examine both internal and external jugular veins on both sides as well as venous pulsations which may be visible in the suprasternal notch or in the supraclavicular fossa.

2-The right IJV is superior for accurate evaluation of venous wave form due to:

- Direct continuouty with RA.


Clinical cardiology ov erview

- Innominate vein may be compressed by the arch of the aorta, making the left sided venous pressure to be abnormally high in normals.

* Position of the patient:

> The trunk of the body should be elevated until maximum pulsation is noted.

> In most normal subjects the maximum pulsation is usually observed when the trunk is inclined less than 45 (15-30) degree.


Clinical cardiology ov erview

  • Sit the patient up at 45 degree angle with their head turned away from you

  • Remember you are always on the patient,s right side,

    the right JVP is actually closer to the right atrium and so functions

  • Look for a pulsation between the two heads of the sternocleidomastoid

  • Light should be tangential to illuminate

  • highlights and shadows.

  • Neck should not be sharply flexed.

  • Using a centimeter ruler, measure the

  • level of jugular vein pulsation.

  • A straight edge intersecting the ruler

  • at a right angle may be helpful.


Clinical cardiology ov erview

You will assess the JVP for Height and Character:

Height - the height is measured from the sternal angle(of Louis) in a line perpidicular to the floor.

* JVP is considered raised if > 3cm (note: some may say it is raised if >8cm and the reason for this is that somepeople are purists, and so they consider the right atrium as 0cm.


Clinical cardiology ov erview

  • Now since the angle of louis is 5 cm above the right atrium,one simply adds 5 cm to any measurement above the angle of Louis for this method of JVP measurement,so donot let that throw you). A raised JVP indicates a raised

  • Right Atrial Pressure which can be from many conditions ie Fluid Overload (iatrogenic), Right Ventricular Fialure.

* Character of the JVP - The wave form of the JVP is complex and you will not be expected tocomment on subtle changes in

these wave forms in different

patients.

* But you will be expected

**NB:

1-The neck muscles especially sternomastoid should be relaxed because if it is tense it will obscure pulsations so place small pillow under the neck or gentle massage by your hand.

2-The head should not rotated or if necessary for few degrees only to avoid tense of neck muscles.

3-Proper evaluation of venous pulsations is possible only when they are correlated with all events of the cardiac cycle.

4- Carotid pulse may be used to time venous pulse.

  • The normal wave form is composed of the following in order:

  • A wave, C wave, X - descent, V wave,

  • Y-descent.

* (a-wave):

Mechanism:

> Retrograde transmission of the pressure pulse produced by atrial contraction, where there is a brief backward flow of blood from right atrium to venae cavae.

>It is the prominent positive wave in normal.

> It is a presystolic wave begins just before first HS.

> Occurs at the moment of (S4) if present


Clinical cardiology ov erview

* (C-wave):

It is a brief positive wave that interruptes the descent of venous pulse from the summit of (a-wave).

Mechanism:

> Impact of carotid artery adjacent to vein so it is termed (carotid impact)

> Retrograde transmission of pressure pulse due to bulging of TV into RA during RV systole.


Clinical cardiology ov erview

* (V-wave):

Mechanism:

> During ventricular systole the TV is closed, but blood continues to fill the venae cavae and RA leading to increase in the volume and pressure within them. So the pressure rises from the trough of (x-wave) to the positive (v-wave).

> The 2nd HS occurs shortly prior to the summit of v-wave which marks the opening of TV.


Clinical cardiology ov erview

* (X-wave) = Systolic Collapse:

Occurs in late systole, shortly before the 2nd HS.

Mechanism:

> Downward displacement of the base of the ventricles including TV during ventricular Systole  fall in RA pressure.

> Continued atrial Relaxation.


Clinical cardiology ov erview

* (Y- wave) = Diastolic collapse:

Mechanism:

V-wave descent caused by opening of TV & rapid rush of blood from RA to RV.

Ascending limb of Y-wave is produced by continued diastolic inflow of blood into the great veins, RA & RV (which are in free communication during diastole).

The S3 of right side occurs at the moment of Y trough while the S3 of left side occurs shortly before the trough.

Amplitude:

1- Prominent a-wave: Observed when the right atrium contracts against decreased compliance of RV as in pulmonary hypertension & acute pulmonary Embolism.

Abnormalities of the systolic collapse (x-wave):

In tricuspid regurgitation this collapse may be:

 Decreased or

 Obliterated

 or even replaced by a positive wave.

This depends on the degree of tricuspid regurgitation (TR):


Clinical cardiology ov erview

> Mild TR decreases the systolic collapse.

> Moderate TR causes obliteration or small regurgitant (r-wave).

> severe TR  systolic expansion  large r-wave.

** in this case  S wave or what is called Arterialization of neck vein, or, ventricularization of neck vein.

** In constrictive pericarditis :

The predominant wave is sharp deep Y-descent.

X-descent is shallow.

N.B : X-descent may be prominent & deep than Y-descent if it is associated with active pericaiditis.


Clinical cardiology ov erview

Abnormalities of the diastolic collapse (Y-wave).

The down slope of the Y descent or V-wave depends on:

Height of RA & great venous pressure

Estimation of central venous pressure:

>First position the patient to get a good view of the internal jugular and its oscillations.

>Identify the highest point of pulsation, which usually occurs during exhalation and coincides with the peak of the a and v waves.

*Hepatojugular (Abdominojugular Reflux):

it is termed the one-minute Abdominal compression tests: firm pressure over the right upper quadrant of the abdomen for 60 seconds.  Abnormal elevation of the internal jugular pressure indicates that the right ventricle cannot accept the increased venous return caused by abdominal compression.

**Kussmaul’s sign:  Paradoxic increase in jugular venous distension during inspiration.

Observed in:

> Severe right – sided heart failure.

> Constrictive pericarditis.

> Right ventricular infarction.

> Restrictive cardiomyopathy.

> Tricuspid stenosis.

> Superior vena cava syndrome.


Clinical cardiology ov erview

The external Jugulars are less suited for venous pulsations examination due to:

> They often become compressed while going through the various fascial planes of neck.

> They have valves that may prevent adequate transmission of right atrial pulsation.

> They are so constricted, in patients with increased sympathetic activity.

> They are not in straight line with right atrium.

Jugular venous findings of a right ventricular Infarction:

> The mean JVP is increased.

> Prominent a-wave.

> Prominent X and Y descents.

> Positive abdominojugular reflux.

> Concomitant tricuspid regurgitation, gives additional findings (such as giant V-waves and right earlobe bobbing ) .

Significance of neck veins in differentiating the type of pericardial disease:

* In tamponade: there is an X-descent but little or no Y descent, where there is much restriction from the begining of diastole.

* Constrictive pericarditis: there is a shallow X-descent and deep Y descent, when the restriction occurs only after the opening of tricuspid valve.

* Effusive -constrictive pericarditis: the X-descent is more or less equal to the Y- descent.

* Bernheim Effect:

left ventricle bulge into RV during diastole prevents good RV filling, but does not prevent the RV outflow (SO it is a type of inflow obstruction, not an outflow obstruction).

-Prominant a-wave.

-Decrease in Y-descent.

-Increase in X-descent.

* Sustained apex:

> It is the apex that remains outward throughout systole and begins to fall a way only with second beart sound.

*Significance:

a- A significant finding of aortic stenosis.

b- May be due to ventricular aneurysm involving apex.

c- If the apex is palpated in axilla and it is sustained it may be due to complete absence of pericardium.

d- In HOCM sustained apex means severe left ventricular hypertrophy or in absence of LVH, it means decrease in ejection fraction.


Clinical cardiology ov erview

Palpable presystolic impulse at the apex:

> Atrial hump due to strong left atrial contraction & it rounded in contour, it is usually felt in systolic dysfunction.

  • Palpable 4th heart sound: the palpable atrial hump is termed palpable 4th heart sound. It is sharp and associated with auscultated 4th heart sounds.

  • It is observed in patients with impaired diastolic function and with normal systolic function as in HOCM & in hypertension.


Clinical cardiology ov erview

* Presystolic impulse is commonly observed in HOCM, more than aortic stenosis... How?

  • In HOCM, although the interventricular septem is very thick, where the strong atrial kick can easly expand the rest of LV, which is not hypertrophied as the septum.

  • In AS: The entire LV is equally hypertrophied and therefor resists expansion of left atrial contraction.

a) A slight precordial lift may occur in children normally.

b) Bulging of the precordium in childrendenotes longstanding right ventricular enlargement.

c) A localized, sustained heaving lift in the lower left parasternal region denotes right ventricular hypertrophy due to pressure overload. (PS.)

*Auscultate the Carotid arteries for any bruits.

It is important to know physically why a bruit is

produced in any artery.

* Thereis an equation from physics which describes the

parameters necessary to produce a bruit.

* In effect a bruit is the sound made from turbulent flow.


Clinical cardiology ov erview

  • The following is the equation which you should commit to memory if you want high honours:

  • (1) Either the flow is laminar or

  • (2) The carotid is completely 100% stenosed

  • thus producing no flow whatsoever.

  • This can be confirmed

  • because in a completely stenosed carotid artery, the carotid pulse cannot be felt.

(8) EXAMINATION OF THE PRECORDIUM:

Inspection:

-Look for scars: midline sternotomy is

CABG or valve repair,

left or right sided lateral thoracotomy

scars (check under female pendulous breasts)

which may indicat previous closed mitral

or tricuspid valvotomy.

-Look for abnormal rib cage: (i) Pectus excavatum

(ii) Pectus carnatum (iii) Kyphoscoliosis.

* These can be caused by Marfan,s syndrome

which may result in distortion of the position

of the great vessel and displacement of the apex beat.

* If severe, it can cause Pulmonary Hypertension (secondaryto a reductionin pulmonary function).


Clinical cardiology ov erview

  • -Look for pacemaker (under the right or left pectoral muscle)

  • -Look for a visible apex beat

  • -Look for a visible pulmonary artery pulsation due to severe pulmonary hypertension.

* Palpation:

>Apex beat: always begin your palpation

of the apex beat from the axillae towards the

midline.

> Once you can palpate it (the size of a

2 euro coin)count dow the number of

spaces with the left handwhile

maintaining position of the apex with

the right hand.

> Comment on the (i) Position of the

apex beat and (ii) Character of the Apex beat


Clinical cardiology ov erview

(i)Position - the normal position of the apexbeat is 5thintercostal space on the left, and 1 cm medial to

midclavicular line.

> If the apex beatis lateral or inferior to this, it can indicate cardiac enlargement,chest wall deformity, or pleural/pulmonary disease.


Clinical cardiology ov erview

(ii)Character - is described by the following:

* Left vent. Thrust =Normal apex.

* Pressure Loaded - a sustained beat pressing against your hand indicative of aortic stenosis or hypertension.

* Volume Loaded - increased area of the palpated beatwhich is indicative of left ventricular failure (LVF).

** Therefore, the size of the apex beat is larger than the normal 2 euro size.

  • Double Impulse (or triple)

  • - indicative of HOCM,

  • this occurs because the atria contract into hardened ventricles causing a loud S4 sound that is palpable.

  • This loud S4 is palpable just before the tapping of the ventricle that is the apex beat thus giving rise to a double impulse


Clinical cardiology ov erview

Tapping Apex - A palpable S1 (mitral or tricuspid stenosis)

with a normal apex beat which follows.

The S1 is palpablein these stenoses because the atria arestill trying to squeeze

blood passed the stenosed valve when the

ventricle contracts thus slamming the valve shut (if you are trying to close a door while someone on the other side is pushing it open, when youfinally close it....its gonna slam shut.....same idea here).

Auscultation:

Hunt for a Murmur

-(always listen for HS I and II while listening in all the areas)

-Firstplace the bell of your stethoscope over the mitral area

-Rememberto apply the bell of your stethoscope to the chest wall very lightly or else a diaphragm is created bythe stretched skin and this defeats the purpose of usingthe bell


Clinical cardiology ov erview

  • -The low pitched sounds that you would expect to hear over thisarea are that of mitral stenosis or the 3rd heart sound.

  • -Second place the diaphragm of your stethoscope over the mitral area (to listen for high frequency sounds).

  • -Thirdly place the diaphragm at the tricuspid area (5th intercostal space, left sternal edge) and auscultate any murmurs.


Clinical cardiology ov erview

-Next place the diaphragm at the pulmonary area

(2nd intercostal space, left sternal edge) and auscultate

any murmurs.

-Next place the diaphragm at the aortic area

(2nd intercostal space, right sternal edge) and

auscultate any murmurs.

-Next ask the patient to sit forward and place the

diaphragm of your stethoscope between

both shoulder blades,

  • -Whenever you hear a murmur, make sure to simultaneously

  • listen to the murmur and feel for a radial or

    carotid pulse todetermine if the murmur is systolic

  • (occurs with each beat of your pulse)

  • or diastolic (occurs in between each beat of your pulse).

* Heart Sounds I,II, III, IV and the Split:

The following is the sort of abnormalities you may hear when listening to the heart sounds:

Heart Sound I(which is the closure of the tricuspid and mitral valves)

Loud HS I = occurs whenever the flow from the atria to the ventricles is still high pressure and high volume when the ventricles start contracting thus closing these valves despite the continued

high pressureand high volume flow).


Clinical cardiology ov erview

  • Soft HS I = occurs whenever the pressured volume of flow from atria to ventricles is long gone (the flow is complete) , yet the ventricle has not started contracting yet.

  • As a result, the closure of the valve simply closes softly, donot coapt


Clinical cardiology ov erview

* Loud A2 = if there is systemic hypertension or aortic stenosis

*Loud P2 = in pulmonary hypertension

*Soft A2 or P2 = Aortic (pulmonary) regurgitation or calcification

*Splitting:

** If you think you hear a split second heart sound , note that normally the aortic valve closes before the pulmonary valve due to greater diastolic pressure pushing back on the aortic valve.


Clinical cardiology ov erview

  • Logically then, since inspiration causes increased

    venous return to the right side of the heart which causes larger amount and stronger ejection of venous blood pressing open the pulmonary valve to gain access to the pulmonary artery, thus the closing of thePVis delayed further on inspiration in relation to the closure of the AV.

    ** As a result, splitting of the two heart sounds (I & II) is increased on inspiration.


Clinical cardiology ov erview

Increased Splitting:occurs in pulmonary stenosis, Right bundle branch block, and Ventricular septal defects (because l pressure is greater than R. pressure, the right side becomes fluid overloaded).

Fixed Splitting:occurs in Atrial Septal Defects and this occurs because of equalisation of the 2 atrial pressuresand volumes and thus inability for changein volume to occur on inspiration.


Clinical cardiology ov erview

  • Paradoxical Splitting:occurs in aortic stenosis, aorticcoarctation, hypert. and a large Patent ductus arteriosus which increases the flow to the left atria/ventricles and thus keeps aortic V open longer thus delayingthe A2 component of the second heart sound).


Clinical cardiology ov erview

When one hears a splitting of the second heart sound, it is impossible for you to ascertain whether the split is a regular split (A2 followed by P2) or a paradoxical split

(P2 followed by A2). The only way you can tell is by auscultating while asking the patient to inspire.

If the splitting is increased, then it is a normal split.

If the splitting is decreased, then it is a paradoxical split (note that a paradoxical split occurs when there is aortic stenosis).

  • Extra Heart Sounds:

  • NOTE: the extra heart sounds can only be heard if the

    atria are contracting appropriately, as a result dont say

    that you can hear the S3 sound right after saying that the

    patient has Atrial Fibrillation, because this is impossible.

  • Remember this is the order or pattern of the heart sounds

  • (note the relative distance between the sounds):

  • 4th---------1st----------------------------------------2nd---------3rd


Clinical cardiology ov erview

S3: a low pitched sound arises from the l or Rventricles. It represents rapid ventricular filling

(ie AR or mitral regurgitation) This sound can be normal in young patient <40 yrs old and in pregnant patients.

It occursbecause the ventricle is already

filled with fluid to the brim, so an extra push of fluid


Clinical cardiology ov erview

  • from the atrium causes the ventricle to balloonout causing a low pitched 3rd HS. When it is present, the rhythm that is heard is Ken-----------Tucky.

  • The Ken representing HS1, Tu- representing HS2, and cky- representing HS3.


Clinical cardiology ov erview

S4: a high pitched sound arises from the L or R ventricles.

This sound occurs due to the atria contracting fluid into a non-compliant ventricle.

This heart sound is alwayspathological if heard and it may be due to anything which hardens the ventricle be it hypertrophy or fibrosis (ie aortic stenosis, hypertension, mitral regurgitation,ischaemic heart disease (this heart sound may present duringangina or MI).


Clinical cardiology ov erview

  • If HS3 and HS4 are present at the same time, the soundis referred to a quadruple gallop and it is representativeof severe ventricular dysfunction.

  • If the patient becomes tachycardic (HR > 100bts/min) while having HS3 and HS4

  • simultaneously, these two sounds can become superimposed which is referred to as a summation gallop.


Clinical cardiology ov erview

Additional Sounds:

Opening snap- occurs in mitral stenosis or tricuspid stenosisand it occurs because of difficult

of these valves in first opening.

Ejection Systolic Click - occurs in aortic or pulmonarystenosis (due specifically to bicuspid congenitalvalves)


Clinical cardiology ov erview

  • Non-Ejection Sytolic Click - occurs if there

    are redundant mitral valve leaflets or an ASD

  • Tumour Plop (diastolic) - occurs when one has an atrial myxoma (which occurs in the atria thusthe name) and so on diastole, when the mitralor tricuspid valves open, the tumour plops down into the tricuspid or mitral valve opening.


Clinical cardiology ov erview

  • Pericardial knock (diastolic) - is a sudden cessationof ventricular filling b/c of inability of theventricle to expand any further due to some restrictive

  • extrinsic boundary.

  • Thus, it tends to occur inconstrictive pericarditis.


Clinical cardiology ov erview

  • Prosthetic Heart Valves - you should have some idea of the differencesbetween ball-cage valves anddisc valves (both prosthetic), xenograft tissue valves

  • (porcine valves) do not have a differentsound to

    them because they are tissue!

  • Pacemaker Sound - is a late diastolic high pitched click due to the contraction of the chest wall muscle on pacemaker firing just before ventricular contraction.

* Systolic murmurs:

The very vast majority of murmurs are systolic

When soft they are usually early in systole and

disturb the end of S1. S1 often appears slurred

in these cases as opposed to ending abruptly as

is normally the case

* Mid-late systolic murmurs.

The careful clinician focuses on the end of S1 for soft systolic murmurs.


Clinical cardiology ov erview

  • Holosystolic murmur: refers to a systolic murmur

    that begins during or immediately after S1 and ends with the onset of S2

  • Pansystolic murmur: refers to a systolic murmur that begins during or immediately after S1 and continues into and obscures S2 (note that left ventricular pressure ) continues to be greater than left atrial pressure after aortic valve closure – during isovolumetric contraction).


Clinical cardiology ov erview

Diastolic murmurs:

- Less commen than systolic murmurs

- Low frequency

-Rather low intensity and so are graded

out of 4, not 6

-Best identified with the bell of the

stethoscope

-My be early diastolic , mid0diastolic

or late ( presystolic) murmurs.


Clinical cardiology ov erview

Continuous murmurs:

-Common

-Typically associated with a PDA, but also arteriovenous

fistulas

-Usually vary in intensity throughout the cardiac cycle,

however the murmur is detected at all times

-The continuous nature of the murmur may only be

noted at the PMI, while at other locations

it may only be systolic, for example.

To and Fro murmurs:

The name for the situation when a systolic murmur

and a diastolic murmur (due to different physiologic

etiologies) coexist.


Clinical cardiology ov erview

Intensity:

The intensity of the murmur at its origin is related to (Blood flow velocity) x (Rate of flow).

* Overall, the intensity of a heart murmur is not related to the severity of the lesion;

however for some diseases there is a rough correlation between the intensity of the murmur and the severity of the lesion such as:

Mitral valve insufficiency Aortic / subaortic valve stenosis Pulmonic valve stenosis


Clinical cardiology ov erview

The intensity of a murmur is graded on a scale of 1 to 6:

Grade 1 = a very soft, localized murmur detected only after several minutes of listening.

Grade 2 = a soft murmur, heard immediately but localized to a small area.

· Grade 3 = a moderately intense murmur that is readily detected and detected over more than one location.


Clinical cardiology ov erview

  • Grade 4 = a moderately intense or loud murmur,

    detected over several areas, usually both sides of the

    chest, however a precordial thrill is not detected in this case.

  • Grade 5 = a loud murmur accompanied by a precordial

    thrill over the point of maximal intensity.

  • Grade 6 = a very loud murmur accompanied by

    a precordial thrill and the murmur is detected when

    the stethoscope is pulled slightly off the chest wall.
