Variables Included in Guideline‐Recommended Scores for Post‐MI Risk Stratification
| GRACE (Range, 1–263) | TIMI‐STEMI (Range, 0–14) | TIMI‐NSTEMI (Range, 0–7) |
|---|---|---|
| Age (7 categories) | Age (2 categories) | Age ≥65 y |
| HF history | Diabetes mellitus, hypertension, or angina | 3≥CAD risk factorsa |
| Prior MI | Systolic blood pressure <100 mm Hg | Prior coronary stenosis >50% |
| Resting heart rate (7 categories) | Heart rate >100 bpm | ST‐segment deviation |
| Systolic blood pressure (7 categories) | Killip class >1 | Pre‐MI angina |
| ST‐segment deviation | Weight <67 kg | Aspirin use in past 7 d |
| Initial serum creatinine (7 categories) | LBBB or anterior ST elevation | Elevated cardiac biomarkersb |
| Elevated cardiac enzymes | Time to treatment >4 h | |
| No in‐hospital PCI |
bpm indicates beats/min; CAD, coronary artery disease; GRACE, Global Registry of Acute Coronary Events; HF, heart failure; LBBB, left bundle branch block; MI, myocardial infarction; NSTEMI, non–ST‐segment elevation MI; PCI, percutaneous coronary intervention; STEMI, ST‐segment elevation MI; and TIMI, Thrombolysis in Myocardial Infarction.
a
Risk factors included family history of CAD, hypertension, hypercholesterolemia, or diabetes mellitus, or being a current smoker.
b
Creatine kinase MB fraction and/or cardiac‐specific troponin level.
