TIMI Risk Score

The Thrombolysis in Myocardial Infarction (TIMI) risk score uses seven variables to identify patients with acute coronary syndromes who are at risk for death, myocardial infarction, or recurrent ischemia within 14 days after hospitalization.

These include age greater than 65 years, three or more risk factors for atherosclerosis, known coronary artery disease, two or more episodes of anginal chest pain in the 24 hours before hospitalization, the use of aspirin in the 7 days before hospitalization, ST-segment deviation of 0.05 mV or more, and elevated serum markers for myocardial necrosis (troponin or creatine kinase MB).

Patients with three or more of the seven variables are considered to be at high risk, whereas those with no more than two of the variables are considered to be at low risk.
