what is cardiac failure
What is Cardiac Failure?
  • Definition

“ A chronic or acute state that results when the heart is not capable of supplying the oxygen demands of the body”

(Tortora & Anagnostakos 1990)

classification of cardiac failure nicolas 2004
Classification of Cardiac Failure (Nicolas 2004)
  • Class 1: Patient asymptomatic, ordinary physical activity does not cause SOB or palpitation
  • Class 2: Patient comfortable at rest ordinary physical activity causes fatigue, palpitations or SOB
  • Class 3: Patient has marked limitation of physical activity though comfortable at rest
  • Class 4: Patient unable to carry out any physical activity without causing discomfort
types of cardiac failure waugh grant 2002
Types of Cardiac Failure (Waugh & Grant 2002)
  • Acute Cardiac Failure

Sudden Decrease in output of blood from both ventricles resulting in acute reduction in blood supply

  • Chronic Cardiac Failure

Develops gradually and there may be no symptoms because of compensatory changes – if compensation no longer possible there is a decline in myocardial efficiency

manifestations of cardiac failure waugh grant 2002
Right Sided (Congestive) Cardiac Failure

Pressure developed within right ventricle is less than the force to push it through the lungs

Right atrium and venae cavae become congested with blood

congestion through venous system

Left Sided Ventricular failure

Pressure in Left ventricle is less than the pressure in the aorta

Incomplete emptying of the ventricle

Results in dilation of the atrium and an increase in the pulmonary blood system eventually resulting in systemic venous congestion

Manifestations of cardiac failure (Waugh & Grant 2002)

  • Bi-Ventricular Failure

Left Ventricular MI combined with a right Ventricular MI

causes of cardiac failure puttaroo 2004
Primary causes

Ischaemia

Myocardial infarction

Cardiac tamponade/pericardial effusion

Hypertensive heart disease

Valve disease

Drugs e.g. Tricylic antidepressants

Electrolytes

Hypothermia

Electrocution

Cardiomyopathy

Pericarditis

Rheumatic Heart Disease

Septal defect

Secondary Causes

Asphyxia

Airway obstruction

Apnoea

Tension pneumothorax

Severe blood loss

Hypoxaemia

Septic Shock

Pregnancy

Severe Anaemia

Systemic Lupus

Thyrotoxcsis

Alcohol

Causes of Cardiac Failure (Puttaroo 2004)
management of cardiac failure ayers 2005
Management of Cardiac Failure(Ayers 2005)

Nurse led MDT intervention has resulted in substantial benefits (Alexander et al 2000)

  • Clinical management – Angiotensin-converting enzyme (ACE) Inibitors; Beta-blockers, digoxin and diuretics
  • Education – explanation of diagnosis home monitoring pharmacokinetics & early symtom recognition
  • Palliative care – access to palliation services for patients with end stage cardiac failure
  • Supplementary Support Services – new conditions may present such as diabetes, renal failure & anaemia – appropriate referral service
