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
Class IV (shock) carries very high mortality.
When to use
Early prognosis in acute myocardial infarction.
How it works
Class I (no failure) to IV (cardiogenic shock); mortality rises steeply with class.
Key points
- Class IV (shock) carries very high mortality.
- Bedside assessment, no labs needed.
- Signals need for intensive management.

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.

→Killip classII
- Approx. in-hospital mortality：~15%
| Killip class | I — No clinical heart failure |

→Killip classI
- Approx. in-hospital mortality：~5%

FAQ
Frequently asked questions
- Does Killip Classification (Acute MI) 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 Killip Classification (Acute MI) calculated in practice? Can you show a worked example?
- Inputs: Killip class II — Rales/crackles, S3, or raised JVP → Result: Killip class II（Approx. in-hospital mortality: ~15%） Inputs: Killip class I — No clinical heart failure → Result: Killip class I（Approx. in-hospital mortality: ~5%）
