A simplified TIMI risk score was computed and was found to have similar prognostic ability as the 7 variable TIMI risk score.

Four of the 7 TIMI risk factors (age ≥65 years, ST segment deviation ≥0.5 mm elevated troponin I, and coronary stenosis ≥50%) were independently associated with adverse events. The mean TIMI risk score was significantly higher in patients with an adverse event compared with those without (2.6 ± 1.3 vs. At 30 days there were 48 (5%) deaths, 84 (9%) myocardial infarctions, and 49 (5%) coronary revascularization procedures. There were 151 (16%) patients diagnosed with ACS. A multivariate analysis was done to evaluate the independent predictive power of the individual components of the TIMI risk score to predict an adverse event at 30 days (all-cause death, myocardial infarction, and coronary revascularization). We investigated the prognostic utility of the TIMI risk score in 947 consecutive patients evaluated in the ED for possible ACS. The ability of the TIMI risk score to risk stratify patients at initial presentation in the ED with chest pain of unclear etiology is uncertain.

To assess the prognostic utility of the Thrombolysis in Myocardial Infarction (TIMI) risk score in patients in the emergency department (ED) evaluated for possible acute coronary syndrome (ACS).
