TIMI Risk Score (NSTEMI/UA) calculator
Result
0/ 7
14-day MACE risk ~4.7%
How to use it
- 1
Score 7 criteria. Each yes/no criterion scores 1 point. Total 0–7.
- 2
Aspirin criterion. Aspirin use despite ACS presentation suggests aspirin failure — a marker of higher risk.
- 3
Interpret. Score 0–2 = low (4–8%), 3–4 = intermediate (13–20%), 5–7 = high (26–41%).
When to use it
- NSTEMI or unstable angina at presentation
- Guides early invasive vs. conservative decision alongside GRACE.
- Comparison with GRACE
- GRACE is more accurate; TIMI is simpler. Use both to triangulate risk.
- Not for STEMI
- TIMI STEMI score is a separate tool.
A reference for clinicians and students, not medical advice. A score supports a decision; it does not make one. Check every result against the patient in front of you and your local protocol.
