TIMI UA/NSTEMI Risk

TIMI Risk Score for Unstable Angina and Non-ST-Elevation MI is calculated as follows:

One point for any of following:

  • Age >65
  • Known CAD (>50% stenosis)
  • Severe anginal symptoms (>2 episodes of chest pain in past 24 hours)
  • ST deviation >0.5 mm on admission EKG
  • Elevated serum cardiac markers
  • Use of ASA in past week
  • 3 or more risk factors from following list:
    • Family Hx
    • DM
    • HTN
    • Hypercholesterolemia
    • Current smoker
    • Obesity

Interpretation:

14-day risk of death, MI, or severe recurrent ischemia requiring urgent revascularization based on score

0 or 1: 4.7%
2: 8.3%
3: 13.2%
4: 19.9%
5: 26.2%
6 or 7: 40.9%
