This-shift next steps
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 →

Methodology · worked example, guidelines & full notes
Score 0–1 ~5%, 6–7 ~41% 14-day event risk.
When to use
Risk-stratify non-ST-elevation acute coronary syndromes.
How it works
1 point each: age ≥ 65, ≥ 3 CAD risk factors, known CAD, aspirin in 7 days, ≥ 2 anginal episodes/24 h, ST deviation ≥ 0.5 mm, elevated markers.
Key points
- Score 0–1 ~5%, 6–7 ~41% 14-day event risk.
- Use alongside troponin trend and clinical context.

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 | No |
|---|---|
| ≥ 3 CAD risk factors | No |
| Known CAD (stenosis ≥ 50%) | No |
| Aspirin use in past 7 days | No |
| ≥ 2 anginal episodes in 24 h | No |
| ST deviation ≥ 0.5 mm | No |
| Elevated cardiac markers | No |
→TIMI0/7
- 14-day event risk：≈ 4.7% (death/MI/urgent revascularisation)
- Strategy：Lower risk — guideline-directed medical therapy, risk-guided.
| Age ≥ 65 | Yes (+1) |
|---|---|
| ≥ 3 CAD risk factors | Yes (+1) |
| Known CAD (stenosis ≥ 50%) | Yes (+1) |
| Aspirin use in past 7 days | Yes (+1) |
| ≥ 2 anginal episodes in 24 h | Yes (+1) |
| ST deviation ≥ 0.5 mm | Yes (+1) |
| Elevated cardiac markers | Yes (+1) |
→TIMI7/7
- 14-day event risk：≈ 40.9% (death/MI/urgent revascularisation)

FAQ
Frequently asked questions
- Does TIMI Risk Score (UA/NSTEMI) 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 (UA/NSTEMI) calculated in practice? Can you show a worked example?
- Inputs: Age ≥ 65 No, ≥ 3 CAD risk factors No, Known CAD (stenosis ≥ 50%) No, Aspirin use in past 7 days No, ≥ 2 anginal episodes in 24 h No, ST deviation ≥ 0.5 mm No, Elevated cardiac markers No → Result: TIMI 0 /7（14-day event risk: ≈ 4.7% (death/MI/urgent revascularisation), Strategy: Lower risk — guideline-directed medical therapy, risk-guided.） Inputs: Age ≥ 65 Yes (+1), ≥ 3 CAD risk factors Yes (+1), Known CAD (stenosis ≥ 50%) Yes (+1), Aspirin use in past 7 days Yes (+1), ≥ 2 anginal episodes in 24 h Yes (+1), ST deviation ≥ 0.5 mm Yes (+1), Elevated cardiac markers Yes (+1) → Result: TIMI 7 /7（14-day event risk: ≈ 40.9% (death/MI/urgent revascularisation), Strategy: [Pending update] Some thresholds, grades and management recommendations on this page that conflict with current guidelines or are unverified are temporarily hidden pending verification against the guideline text.）
