It is estimated that almost 2 million people in England currently have or have had angina. Being diagnosed with angina can have a significant impact on a person's quality of life, restricting daily work and leisure activities. Stable angina is a chronic medical condition with a low but appreciable incidence of acute coronary events and increased mortality. The aim of management is to stop or minimise symptoms, and to improve quality of life and long-term morbidity and mortality. Management options include lifestyle advice, drug treatment and revascularisation using percutaneous or surgical techniques. Analysis of the comparative efficacy of different treatments for people with stable angina is difficult because of the advances in drug treatment and revascularisation strategies over several decades. Trials of drug treatment versus coronary artery bypass surgery were carried out more than 25 years ago and showed a survival advantage with surgery in patients with severe coronary artery disease. Statins and other secondary prevention treatments were not used when the trials were carried out and these treatments have a significant effect on morbidity and mortality. Percutaneous revascularisation techniques have developed, from balloon angioplasty to bare metal stents and drug eluting stents and each is associated with reduced rates of repeat revascularisation compared with the previous technique. All trials, including trials of revascularisation strategies, have been limited to people considered suitable for the intervention rather than being representative of the whole population with angina. The recommendations in this guideline relate only to people with a diagnosis of stable angina. Coronary artery disease can also present as acute coronary syndromes, such as unstable angina or myocardial infarction. The NICE guideline on recent-onset chest pain of suspected cardiac arrest origin, covers the diagnosis of stable angina and should be read in conjunction with this guideline.
