TIMI Risk Score (NSTEMI)

Estimates the 14-day risk of all-cause mortality, new/recurrent MI, or severe ischemia requiring urgent revascularization.

Please manually add 1 point for each of the 7 criteria below (Max 7 points).

Age ≥ 65 years

≥ 3 CAD Risk Factors (HTN, Hyperlipidemia, Diabetes, Family Hx, Smoker)

Known CAD (Stenosis ≥ 50%)

Aspirin use in the past 7 days

Severe Angina (≥ 2 episodes in 24 hours)

ST deviation ≥ 0.5 mm

Elevated cardiac markers (Troponin/CK-MB)

TIMI vs GRACE

While the TIMI score is simpler to calculate at the bedside because it assigns 1 point to each criteria, the GRACE score has been shown to be superior for predicting mortality and is preferred by current guidelines.

14-Day Risk of Ischemic Events

Score 0-1: 4.7% (Low Risk)
Score 2: 8.3% (Low Risk)
Score 3: 13.2% (Intermediate Risk)
Score 4: 19.9% (Intermediate Risk)
Score 5: 26.2% (High Risk)
Score 6-7: 40.9% (High Risk)
