TIMI Risk Score (UA/NSTEMI)

Estimates 14-day risk of death, MI, or urgent revascularization in unstable angina/NSTEMI. Distinct from the separate TIMI STEMI score, which is not this tool.

For healthcare professionals.These calculate a score or a measurement from values you enter. They do not diagnose, and they are no substitute for clinical judgement. If you are a patient, discuss any result with your own doctor rather than acting on it.

Age ≥ 65 years

≥3 CAD risk factors (family history, HTN, hypercholesterolemia, diabetes, current smoker)

Known CAD (stenosis ≥ 50% on prior angiography)

Aspirin use in the past 7 days

≥2 anginal episodes in the past 24 hours

ST deviation ≥ 0.5 mm on presenting ECG

Elevated cardiac biomarkers (troponin or CK-MB)

Result

0 / 7

14-day risk of death, MI, or urgent revascularization: ~4.7%. Guideline-suggested threshold: score ≥3 favors an early invasive strategy.
