Thrombolysis in Myocardial Infarction (TIMI) Score for Unstable Angina Non ST Elevation Myocardial Infarction

 

		Age ≥65 (1 point)
		3 or more CAD risk factors (1 point)
		Known CAD with more than 50% stenosis (1 point)
		Aspirin use in the past 7 days (1 point)
		Severe angina in the preceeding 24 hours (1 point)
		Elevated cardiac markers (1 point)
		ST deviation greater than 0.5 mm (1 point)

 

Total Criteria Point Count:
 

 

TIMI Score and 2 week Death / MI Risk ** Death / MI / Urgent Revasc Risk Interpretation

 

0 to 1 Point:	3% ** 5%
2 Points:	3% ** 8%
3 Points:	5% ** 13%
4 Points:	7% ** 20%
5 Points:	12% ** 26%
6 to 7 Points:	19% ** 41%

 

Notes

• Entry criteria:UA or NSTEMII defined as ischemic pain at rest within past 24H, with evidence of CAD (ST segment deviation or +marker).
• CAD risk factors included hypertension, family history of CAD, elevated cholesterol, diabetes, and smoking.
