TIMI Risk Score for UA / NSTEMI Calculator

Sum of 7 binary predictors (0–7) for 14-day adverse events.

Compute the TIMI risk score for unstable angina / non-ST-elevation MI (UA/NSTEMI). Sum 1 point each for: age ≥ 65, ≥ 3 CAD risk factors, known CAD (≥ 50 % stenosis), aspirin use in last 7 days, ≥ 2 anginal events in 24 h, ST deviation ≥ 0.5 mm, positive cardiac biomarker. Higher score = higher 14-day mortality / MI / urgent revascularization.
