TIMI Risk Score (UA/NSTEMI)
Medical context
Estimate risk in unstable angina / NSTEMI using the TIMI risk score.
Cardiology and medicine teams use this with ECG, biomarkers, and guideline-directed therapy context.
This page explains the TIMI formula, how to interpret the output, known limitations, and peer-reviewed references so you can verify results against primary sources and local protocols.
It is grouped under Cardiology because stroke prevention, acs risk, and cardiac indices.
How to use this calculator
- Enter the values requested by the TIMI calculator using the units shown beside each field.
- Review the calculated result and read the interpretation section before acting on the output.
- Check limitations and references if the result will change management, dosing, or disposition.
- Use the related calculators section when you need supporting values (for example electrolytes, weight, or complementary risk scores).

Formula
Seven dichotomous predictors; score 0–7.
Interpretation
Higher scores correlate with higher short-term adverse cardiac event rates and inform acuity of management.
Limitations
Not for STEMI reperfusion decisions. Use with troponin pathway and guidelines.
Frequently asked questions
- Is this the STEMI TIMI score?
- No — this is the UA/NSTEMI version (0–7).
- Is the TIMI result enough to make a treatment decision?
- No. Calculators support medical decision-making but do not replace examination, shared decision-making, institutional protocols, or consultant input when stakes are high.
- Does Calcmedical store the values I type in?
- Inputs are processed in your browser for this session. We do not ask for patient names or medical record numbers. See our privacy policy for hosting and analytics details.
