When to use
Early prognostic stratification at STEMI presentation.
How it works
Weighted: age 65–74 (2)/≥75 (3), DM/HTN/angina (1), SBP < 100 (3), HR > 100 (2), Killip II–IV (2), weight < 67 kg (1), anterior STEMI/LBBB (1), time to treatment > 4 h (1).
Key points
- Mortality rises steeply with score.
- Provides prognosis, not a reperfusion decision.
- Distinct from the TIMI UA/NSTEMI score.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Age | < 65 (0) |
|---|---|
| Diabetes, hypertension or angina | No |
| Systolic BP < 100 mmHg | No |
| Heart rate > 100 bpm | No |
| Killip class II–IV | No |
| Weight < 67 kg | No |
| Anterior STEMI or LBBB | No |
| Time to treatment > 4 h | No |
→TIMI STEMI0/14
- Risk：Low risk
- Note：30-day mortality rises steeply with score (≈ 1% at 0 to > 30% at ≥ 8 in the original cohort).
| Age | ≥ 75 (3) |
|---|---|
| Diabetes, hypertension or angina | Yes (+1) |
| Systolic BP < 100 mmHg | Yes (+3) |
| Heart rate > 100 bpm | Yes (+2) |
| Killip class II–IV | Yes (+2) |
| Weight < 67 kg | Yes (+1) |
| Anterior STEMI or LBBB | Yes (+1) |
| Time to treatment > 4 h | Yes (+1) |
→TIMI STEMI14/14
- Risk：High risk
- Note：30-day mortality rises steeply with score (≈ 1% at 0 to > 30% at ≥ 8 in the original cohort).

- Inputs: Age < 65 (0), Diabetes, hypertension or angina No, Systolic BP < 100 mmHg No, Heart rate > 100 bpm No, Killip class II–IV No, Weight < 67 kg No, Anterior STEMI or LBBB No, Time to treatment > 4 h No → Result: TIMI STEMI 0 /14（Risk: Low risk, Note: 30-day mortality rises steeply with score (≈ 1% at 0 to > 30% at ≥ 8 in the original cohort).） Inputs: Age ≥ 75 (3), Diabetes, hypertension or angina Yes (+1), Systolic BP < 100 mmHg Yes (+3), Heart rate > 100 bpm Yes (+2), Killip class II–IV Yes (+2), Weight < 67 kg Yes (+1), Anterior STEMI or LBBB Yes (+1), Time to treatment > 4 h Yes (+1) → Result: TIMI STEMI 14 /14（Risk: High risk, Note: 30-day mortality rises steeply with score (≈ 1% at 0 to > 30% at ≥ 8 in the original cohort).）
