Angina (chronic stable).

Introduction Stable angina is usually caused by coronary atherosclerosis, and affects up to 16% of men and 10% of women aged 65–74 years in the UK. Risk factors include hypertension, elevated serum cholesterol levels, smoking, physical inactivity, and overweight. People with angina are at increased risk of other cardiovascular events and mortality compared with people without angina. Among people not thought to need coronary artery revascularisation, annual mortality is 1–2% and the annual non-fatal myocardial infarction (MI) rate is 2–3%.
