Example
- Age
- 70 years
- History of 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 ST-elevation or LBBB
- Yes
- Time to treatment > 4 hours
- Yes
Result: TIMI-STEMI 4 of 14: 7.3% 30-day mortality (Morrow).

What the result means
- Points (0-14)
- 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 STE/LBBB = 1; time > 4 h = 1.
- 30-day mortality
- Observed rate by score: 0 = 0.8%, 2 = 2.2%, 4 = 7.3%, 6 = 16.1%, 8 = 26.8%, > 8 = 35.9% (Morrow derivation cohort).
