How to Use TIMI Score Calculator (UA/NSTEMI)
The TIMI Score Calculator (UA/NSTEMI) uses seven yes/no criteria. Check age 65 or older, at least three CAD risk factors, known CAD stenosis, recent severe angina, aspirin use, ST deviation and elevated cardiac markers.
Each Yes answer adds one point, so the total ranges from 0 to 7. The result updates immediately and shows how many criteria are positive.
Formula & Theory - TIMI Score Calculator (UA/NSTEMI)
The UA/NSTEMI TIMI score is intentionally simple. It uses equal one-point criteria, making it easy to audit at the bedside and straightforward to implement in a front-end form. Higher scores generally imply higher short-term ischemic-event risk.
This tool covers the classic seven criteria only. It does not replace serial troponins, GRACE scoring, angiography planning or clinical instability assessment.
TIMI UA/NSTEMI score = 1 point each for:
Age ≥ 65
At least 3 CAD risk factors
Known CAD stenosis ≥ 50%
Severe angina in the past 7 days
Aspirin use in the past 7 days
ST deviation ≥ 0.5 mm
Elevated cardiac markers
Total range = 0-7 pointsUse Cases for TIMI Score Calculator (UA/NSTEMI)
Use it in ACS education, chest-pain pathway pages, handoff aids and patient-record review. The yes/no structure is especially useful when the page needs to explain exactly why the score increased.
