The Scottish Intercollegiate Guidelines Network (SIGN) has published SIGN 151 on Management of stable angina

Angina is the main symptom of myocardial ischaemia; it is usually connected to restricted blood flow and oxygen delivery to heart muscle due to atherosclerosis.

There is an increased risk of cardiac events associated with stable angina, and it can affect quality of life and restrict work or leisure activities. In one survey, patients with angina scored their general health as twice as poor as those who had experienced a stroke. 

The aim of management is to improve long-term quality of life through minimising or preventing symptoms, and to improve long‑term morbidity and mortality.

The areas covered by SIGN 151 include:

  • diagnosis and assessment
  • pharmacological management
  • cardiac interventions and surgery
  • non-cardiac surgery
  • psychological health.
