Table 1: Diagnostic criteria for acute coronary syndrome.
STEMI |
Symptoms of myocardial ischemia in association with • Persistent ECG ST elevation and subsequent release of biomarkers of myocardial necrosis • ST elevation at the J point in at least 2 contiguous leads of ≥ 2 mm (in men) or ≥ 1.5 mm (in women) in V2-V3, or ≥ 1 mm in other contiguous chest or limb leads |
NSTEMI |
Symptoms of myocardial ischemia in association with ST and/or T wave changes, ongoing pain, and elevated troponin T |
Unstable angina |
Symptoms of rest angina (> 20 min), new- onset angina of at least CCS* class III severity, or increasing angina (more frequent, longer in duration, or lower in • Non-diagnostic ECG or ST/T wave changes • Normal troponin level • Flow-limiting stenosis on coronary angiogram (if angiogram done) *Canadian Cardiovascular Society |
