Angina, unstable - Acute coronary syndrome

Angina, unstable

Acute coronary syndrome

Acute coronary syndrome (ACS for short) is a general term. Doctors use it to refer to three serious heart problems that can happen when your heart can't get enough oxygen:

Unstable angina
A type of heart attack called ST segment elevation myocardial infarction (STEMI for short)
A type of heart attack called non-ST segment elevation myocardial infarction (non-STEMI for short).

The names STEMI and non-STEMI are based on the changes that doctors see on a test called an electrocardiogram (ECG). They use this test to diagnose these conditions. See Electrocardiogram.

The main symptom of all three conditions is chest pain or discomfort. The big difference between them is that heart attacks can damage your heart, whereas unstable angina does not. That's why it's important to stop unstable angina from turning into a heart attack.
