How is the TIMI score for NSTEMI calculated?

One point each for: age ≥65 years; ≥3 CAD risk factors (HTN, DM, dyslipidemia, smoking, family history); prior coronary stenosis ≥50%; ST deviation ≥0.5 mm on presenting ECG; ≥2 anginal events in prior 24 hours; ASA use in prior 7 days (paradox marker of high risk); elevated serum cardiac markers.

What does each TIMI score mean?

Score 0–1: 5% 14-day MACE; Score 2: 8%; Score 3: 13%; Score 4: 20%; Score 5: 26%; Score 6–7: 41%. Scores ≥3 are considered high risk warranting early invasive strategy.

How does TIMI-NSTEMI differ from TIMI-STEMI?

TIMI-NSTEMI risk score stratifies risk among NSTEMI/UA patients (0–7 points). TIMI-STEMI is a separate score (0–14 points) predicting 30-day mortality specifically in STEMI treated with fibrinolysis, and includes anterior ST elevation and time to treatment.

TIMI Risk Score for NSTEMI/Unstable Angina

Calculates the TIMI (Thrombolysis in Myocardial Infarction) risk score for NSTEMI and unstable angina (0–7 points): age ≥65, ≥3 CAD risk factors, known CAD (stenosis ≥50%), ST deviation, ≥2 anginal events in 24h, aspirin use in past 7 days, elevated cardiac markers.
