Table 1. The Thrombosis in Myocardial Infarction (TIMI) Risk Score for Unstable Angina (UA)/Non-ST Elevated Myocardial Infarction (NSTEMI)2
Baseline Characteristics (1 point for each of the following):TIMI Risk Score (points)Rate of Composite Endpoint (%)
Age ≥65 years; At least 3 risk factors for CAD*; Prior coronary stenosis ≥50%; ST segment deviation; At least 2 anginal events in last 24 hours; Use of aspirin in last 7 days; Elevated serum cardiac biomarkers0–14.7
  • * Risk factors include family history of CAD, hypertension, hypercholesterolemia, diabetes, or being a current smoker.

  • CKMB fraction and/or cardiac-specific troponin level.

  • All-cause mortality, new or recurrent MI, or severe recurrent ischemia requiring urgent revascularization through 14 days after randomization.

  • CAD, coronary artery disease; MI, myocardial infarction; CKMB, MB fraction of creatine kinase.
