TIMI Risk Score for UA/NSTEMI and STEMI

This calculator estimates the risk of death and ischemic events for patients with unstable angina or myocardial infarction. Select answers to determine your TIMI risk score and category.

1. Age 65 years or older?

2. At least 3 risk factors for CAD?

3. Known coronary artery disease (stenosis ≥ 50%)?

4. Use of aspirin in the last 7 days?

5. Severe angina (≥ 2 episodes in 24 hours)?

6. ST segment changes ≥ 0.5 mm?

7. Elevated cardiac markers?

TIMI Risk Score ranges from 0 to 7 points. Higher scores indicate greater risk of death, myocardial infarction, or urgent revascularization within 14 days.

Use this score for patients with unstable angina or NSTEMI to guide management and risk stratification.
