TIMI risk score

Associate Editor-In-Chief:

TIMI Risk Score for Unstable Angina
The TIMI risk score for unstable angina was derived in the test cohort by selection of independent prognostic variables using multivariate logistic regression, assignment of value of 1 when a factor was present and 0 when it was absent, and summing the number of factors present to categorize patients into risk stratification.

Total possible score is 7.


 * Age (greater than 65 years) = 1
 * Cardiac enzymes (raised serum cardiac markers) = 1
 * EKG (ST segment depression at presentation) = 1
 * Risk factors (at least three for coronary artery disease) = 1
 * Ischemia (at least two anginal events in previous 24 hours) = 1
 * Coronary artery stenosis (prior stenosis of 50% or more) = 1
 * Aspirin (use in previous 7 days) = 1

TIMI Risk Score for STEMI
Total possible score is 14


 * Demographic data and medical history
 * Age ≥75 years = 3
 * Age 65–74 years = 2
 * History of diabetes mellitus or hypertension or angina = 1


 * Physical examination
 * Systolic blood pressure <100 = 3
 * Heart rate >100 = 2
 * Killip class II–IV = 2
 * Weight <67 kg = 1


 * Evaluation at presentation
 * Anterior ST elevation or left bundle branch block = 1
 * Time to therapy >4 h = 1
