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.

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.
| Killip class | I — No clinical heart failure |
|---|
→Killip classI
- Approx. in-hospital mortality：~5%
| Killip class | IV — Cardiogenic shock |
|---|
→Killip classIV
- Approx. in-hospital mortality：~60–80%
