Stable Angina: M anagement according to NICE guidelines

1. Stable Angina: Management according to NICE guidelines Primary Care Cardiac Service

2. Definition of AnginaBritish Heart Foundation (https://www.bhf.org.uk) • A pain or discomfort most commonly felt in chest, which may also be felt in the arms, neck, stomach or jaw. • Angina occurs when coronary arteries become narrowed and not enough oxygen rich blood can reach the heart muscle, particular when its demands are high, such as during exercise.

3. Angina is the main symptom of myocardial ischemia and is usually caused by atherosclerotic plaque, obstructing the coronary artery, restricting blood flow, and therefore oxygen delivery to heart muscle. • Provide advice & information about infections & infection prevention & control issues • Write & update infection prevention & control policies that are available on the POD • Provide training & education • Conduct audit

4. The Coronary Arteries • The coronary arteries supply the heart muscle with blood so that it can pump efficiently • There are two main branches which split to form a network over the surface of the heart • They are about the size of a drinking straw, 2-3mm across • When the heart beats faster, such as during physical exertion or emotional stress, the coronary arteries open up increasing oxygen and nutrient supply to the demanding heart muscle.

5. The Coronary Arteries in Coronary Heart Disease • The coronary arteries can harden and narrow by the process known as arteriosclerosis. In this process, cholesterol deposits (called plaques) build up in the arterial wall causing the arteries to narrow, restricting blood flow to the heart muscle and causing angina. • There is also a risk that the plaque may break down, causing a blood clot to form. This may block the artery (thrombosis), thereby stopping the blood flow of blood and oxygen to the heart muscle, causing a heart attack (myocardial infarction).

7. Statistics Statistics Team Number of cases: 71,330 men and 48,405 women in 2014. The population of the UK is 64.1 million. Health survey for England in 2006 reported that 8% of men and 3% of women aged 55-64 years had angina. Figures for ages 65-74 were 14% men and 8% women. • British Heart Foundation (https://www.bhf.org.uk • Guidance.nice.org.uk/cg126 • Provide advice & information about infections & infection prevention & control issues • Write & update infection prevention & control policies that are available on the POD • Provide training & education • Conduct audit

8. Types of Angina • stable angina – Chronic medical condition where angina attacks are brought on by an obvious trigger (such as exercise) and improve with medication and rest. • unstable angina – where angina attacks are more unpredictable, occurring with no obvious trigger and continuing despite resting.

9. Risk factors • Smoking • Hypertension • Diabetes • Family history Male <55, Female <65 first degree relative • Raised cholesterol • Overweight • Poor diet • Raised waist measurement • Lack of exercise

10. Angina classification Canadian cardiovascular society angina classification • Class 1 Ordinary activity such as walking or climbing stairs does not precipitate angina • Class 11 Angina precipitated by emotion, cold weather or meals and by walking upstairs • Class111 Marked limitation of ordinary physical activity • Class 1V Inability to carry out any physical activity without discomfort-angina symptoms, may present at rest • (Campeau L. Grading of angina pectoris. Circulation 1976;1976;54(3):522-23 in sign guidelines)

11. Effects • A diagnosis of Angina can have a significant impact on patients level of functioning - in one survey angina scored their general health as twice as poor as those who had had a stroke. • A Tayside study showed that patients with angina had high levels of anxiety and depression. (Smith K, Ross D, Connolly E investigating six month health outcomes of patients with angina discharged from chest pain service, European Journal cardiovascular nursing 2002;1(4):253-64 in sign guideline)

13. Diagnosis Team • Clinical assessment alone. • Clinical assessment plus diagnosis testing. • Use table of people estimated to have coronary artery disease according to typicality of symptoms, age, sex and risk factors.

Simplified, what Nice says about chest pain diagnosis & Control Team • If patient presents with chest pain or had chest pain in last 12 hours with abnormal ecg or unavailable ecg he should be seen as emergency admission. • If ACS suspected but no pain in last 12 hours and ECG normal refer for urgent same day assessment. • If chest pain more than 72 hours, clinical assessment, ECG , Tropi levels, clinical assess how urgent they should be seen. • Provide advice & information about infections & infection prevention & control issues • Write & update infection prevention & control policies that are available on the POD • Provide training & education • Conduct audit

23. Analysis of comparative efficacy of treatments for people with stable angina • Analysis is difficult because of recent advances in medication and revascularisation strategies over several decades • Trials of drug treatments versus coronary artery bypass surgery in patients were carried out more than 25 years ago and showed a survival advantage with surgery in patients with severe coronary artery bypass surgery, but this was pre statins and other secondary prevention treatments and these treatments have had a significant effect on morbidity and mortality. • Provide advice & information about infections & infection prevention & control issues • Write & update infection prevention & control policies that are available on the POD • Provide training & education • Conduct audit
