TIMI Risk Index - Evidencio

Evidencio uses JavaScript for many of its features. Please enable JavaScript to enable calculations

The TIMI Risk Index is a simple calculation that provides important information about mortality in patients across the spectrum of myocardial infarction, STEMI and NSTEMI.

The TIMI Risk Index is intended for patients with ACS or those who are highly suspected to have ACS.

The TIMI Risk Index is not intended for patients without ACS or those who are not suspected to have ACS.

Additional information

The TIMI Risk Index (TRI) was calculated in 337,192 patients from the National Registry of Myocardial Infarction with NSTEMI. Values and outcomes were compared with 153,486 patients with STEMI classified by reperfusion status. Comparisons of baseline characteristics and clinical outcomes stratified by TRI were made.

Characteristics shown concern NSTEMI patients (N = 337,192).
