Risk of Adverse Events* at 14 Days in Unstable Angina or NSTEMI
Scoring | |
|---|---|
Risk Factor | Points |
Age > 65 years | 1 |
CAD risk factors (must have ≥ 3 for 1 point):
| 1 |
Known CAD (stenosis ≥ 50%) | 1 |
1 | |
Two episodes of rest angina in past 24 hours | 1 |
Elevated cardiac biomarkers | 1 |
ST elevation ≥ 0.5 mm | 1 |
Risk level is based on total points: | 1–2 = low 3–4 = intermediate 5–7 = high |
Absolute risk | |
Total Points | Risk of Events at 14 Days (%)* |
0 or 1 | 4.7 |
2 | 8.3 |
3 | 13.2 |
4 | 19.9 |
5 | 26.2 |
6 or 7 | 40.9 |
* Events include all-cause mortality, myocardial infarction, and recurrent ischemia requiring urgent revascularization. | |
CAD = coronary artery disease; MI = myocardial infarction; NSTEMI = non–ST-segment elevation MI; TIMI = thrombolysis in MI. | |
