Age ≥ 65 years

≥ 3 CAD risk factors (family Hx, HTN, hypercholesterolaemia, DM, active smoker)

Known CAD — prior stenosis ≥ 50%

Aspirin use in past 7 days

Severe angina — ≥ 2 episodes in prior 24 hours

ST deviation ≥ 0.5 mm on presenting ECG

Positive cardiac marker (troponin or CK-MB)

TIMI (UA/NSTEMI)/ 7

Low risk

14-day MACE risk: 4.7%
