Calculate the TIMI UA/NSTEMI score as a bedside prognostic summary using the original 14-day composite event framework.
The TIMI Risk Score for UA/NSTEMI is a 7-item bedside score developed from the original TIMI UA/NSTEMI cohorts to estimate the 14-day composite risk of death, new or recurrent myocardial infarction, or urgent revascularization. Each criterion contributes 1 point, which makes the score easy to calculate from the initial history, ECG, and biomarker data.
The score is still useful as a compact prognosis summary, but its event rates come from the original derivation and early validation setting rather than from every modern NSTE-ACS pathway. The most defensible use is to frame short-term risk, not to pretend the number alone decides cath timing or antithrombotic intensity.
This page should be used as one bedside risk-stratification aid within the broader ACS evaluation.
The TIMI UA/NSTEMI score is helpful when you want a quick, standardized way to summarize short-term event risk at presentation. It captures several classic high-risk features without requiring a more complex calculator.
Its value is in bedside prognostic framing. Decisions about invasive evaluation, observation, antithrombotic therapy, and discharge still depend on troponin trend, ECG findings, bleeding risk, comorbidities, and the overall clinical picture.
TIMI UA/NSTEMI Score (7 binary variables, 0-7): Age ≥65: 1 pt ≥3 CAD risk factors: 1 pt Known CAD (≥50% stenosis): 1 pt Aspirin use in past 7 days: 1 pt ≥2 anginal episodes in past 24h: 1 pt ST deviation ≥0.5 mm: 1 pt Elevated cardiac biomarkers: 1 pt Original 14-day composite-event framework: 0-1 (~5%), 2 (~8%), 3 (~13%), 4 (~20%), 5 (~26%), 6-7 (~41%)
Result: TIMI 7/7 — 14-Day MACE ~41%, Very High Risk
All 7 criteria are present, placing the patient in the highest original TIMI UA/NSTEMI event band. The result should be read as a strong short-term risk signal within the broader NSTE-ACS assessment, not as a stand-alone directive for cath timing, ICU placement, or medication choice.
The TIMI UA/NSTEMI score is good at packaging several classic high-risk features into one easy bedside total. That makes it useful when documenting early risk or comparing two presentations.
It does not replace serial troponins, ECG review, bleeding-risk assessment, hemodynamic assessment, or the full NSTE-ACS pathway. A higher score should strengthen clinical attention, not act like an automatic order set.
Use the page as a short-term prognosis summary rooted in the original TIMI framework, then interpret it alongside modern ACS evaluation rather than in isolation.

This page applies the original TIMI UA/NSTEMI risk score by summing the seven published 1-point criteria into the standard 0-to-7 total. It then reports the original 14-day composite event framework of death, new or recurrent myocardial infarction, or urgent revascularization.
The page is meant to summarize short-term risk within the broader NSTE-ACS workup. It should not be used as a stand-alone decision rule for cath timing, antithrombotic intensity, ICU placement, or discharge.
The point reflects a breakthrough event despite aspirin exposure, which was associated with higher short-term event risk in the original cohort. It does not mean aspirin is harmful.
The original TIMI work used the standard traditional CAD risk factors such as hypertension, diabetes, smoking, dyslipidemia, and family history. Having 3 or more of those factors adds 1 point.
GRACE uses a broader variable set and is often more discriminating for overall ACS prognosis, while TIMI is simpler and easier to calculate at the bedside. They are complementary risk tools rather than interchangeable rules.
Any elevated cardiac biomarker counts, including troponin or CK-MB. The result still has to be interpreted with the broader ACS presentation and assay context.
No. A higher TIMI band is one argument for closer evaluation, but invasive timing still depends on the rest of the ACS workup, bleeding risk, comorbidities, hemodynamic status, and the local pathway.
No. STEMI has its own TIMI score with different variables and a different derivation setting.
