After scoring: open the scene pack, peer scores, and the matching pathway. Local reference — no HIS write.
- Who it is for
- Adults with emergency chest pain when deciding observation, rule-out, or ACS.
- Who it is not for
- Chest pain already clearly non-cardiac. No new ECG score.
- Formula and variables
- HEART is history, ECG, age, risk factors, and troponin. GRACE is age, heart rate, systolic pressure, creatinine, Killip, arrest, ST shift, and marker; the variant stays as on this page. TIMI and TIMI STEMI both exist; this page does not pick a new variant. Killip is pump class. No new chest-pain score.
- Result → next step
- Low risk stays with this page’s rule-out or observation. Once ACS is established, the next page is reperfusion and antithrombotic care. Bleeding uses CRUSADE. Stent duration uses the DAPT page. No loading dose is written.No numeric dose until age, weight, renal function, and pregnancy are all known. Pregnancy is contraindication or caution only.ACS reperfusion / antithrombotic →

Clinical takeaway
Mortality rises steeply with score.
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 | 65–74 (2) |
|---|---|
| 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 STEMI2/14
- Risk：Low risk
- Note：30-day mortality rises steeply with score (≈ 1% at 0 to > 30% at ≥ 8 in the original cohort).
| 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).

FAQ
Frequently asked questions
- What are the limits and cautions when using TIMI Risk Score (STEMI)?
- For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
- Does TIMI Risk Score (STEMI) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is TIMI Risk Score (STEMI) calculated in practice? Can you show a worked example?
- Inputs: Age 65–74 (2), 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 2 /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 < 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).）
