TIMI Risk Score Calculator for UA/NSTEMI

Your details

Patient is 65 years of age or older at presentation.
At least 3 of the following: family history of CAD, hypertension, hypercholesterolemia, diabetes mellitus, or current cigarette smoker.
Prior coronary angiography showing at least 50% stenosis in one or more coronary arteries.
Aspirin taken within the last 7 days. Symptoms despite aspirin suggest more severe disease.
At least 2 episodes of angina or anginal equivalent (e.g. dyspnea, diaphoresis) in the 24 hours before presentation.
New or transient ST-segment depression or elevation of 0.5 mm or more on the presenting ECG.
Elevated serum troponin I, troponin T, or CK-MB above the upper limit of normal. This is the single most prognostic criterion.

TIMI Score 0/7 - Low Risk (14-day event rate ~4.7%)

  • No positive criteria are checked. Score of 0 still carries a baseline 14-day event rate of about 4.7%.
  • The TIMI score is a screening tool. Clinical judgment, local protocols, and additional testing always take precedence over any single score.

Next stepLow-risk patients may be candidates for a conservative strategy with stress testing before discharge, but re-evaluate if clinical status changes.
