Thrombolysis in Myocardial Infarction (TIMI)

Several risk stratification ‘scores’ are available and are based on clinical history, ECG findings and cardiac markers [3-5].

One of the most widely used is the Thrombolysis in Myocardial Infarction (TIMI) risk score [3-5]. It estimates 30 day mortality for patients with UA and NSTEMI. Although it can be used for patients with anginal symptoms, it is better suited for patients with confirmed NSTEMI or UA.

What are the components of the TIMI risk score?

The TIMI risk score is composed of seven independent predictor variables, each carrying a similar prognostic weight, shown in the table. The risk score is calculated as a simple arithmetic sum of the number of predictors that apply to an individual patient.
