This quality standard covers diagnosing and managing acute coronary syndromes in adults (aged 18 and over). Acute coronary syndromes are medical emergencies that include myocardial infarction (heart attack) and unstable angina (unexpected, severe chest pain). It describes high-quality care in priority areas for improvement.

It does not cover preventing further cardiovascular disease after a myocardial infarction, which is included in NICE’s quality standard for secondary prevention after a myocardial infarction.

Keeping quality standards up to date

We check our quality standards every August to make sure they are up to date.
