Calculate the TIMI STEMI score as a bedside prognostic summary using the original fibrinolytic-era 30-day mortality framework.
The TIMI Risk Score for STEMI is a bedside clinical score developed from the original fibrinolytic-treated STEMI cohort to estimate 30-day mortality risk at presentation. It combines age, comorbidity burden, hemodynamics, Killip class, body weight, ECG pattern, and delay to treatment into a single total score.
The score is still useful as a compact prognostic summary, but its mortality percentages come from the original derivation setting and should not be treated as perfectly calibrated to modern PCI-era care.
This page should be used as a risk-stratification aid, not as a stand-alone reperfusion, ICU, or mechanical-support decision rule.
A STEMI bedside score can be helpful when you want a quick, structured summary of early risk rather than a loose impression. The TIMI score remains familiar and easy to calculate with variables available at presentation.
Its value is prognostic framing. Treatment decisions still depend on guideline-based STEMI care and the broader clinical picture.
TIMI STEMI Score (0-14): - Age 65-74 years = 2 points - Age 75 years or older = 3 points - Diabetes, hypertension, or prior angina = 1 point - Systolic blood pressure <100 mmHg = 3 points - Heart rate >100 bpm = 2 points - Killip class II-IV = 2-4 points - Weight <67 kg = 1 point - Anterior ST elevation or LBBB = 1 point - Time to treatment >4 hours = 1 point
Result: TIMI STEMI Score 11
A score of 11 places the patient in a very high-risk band within the original derivation framework. The page is summarizing prognosis, not determining reperfusion strategy by itself.
The TIMI STEMI score is good at summarizing early bedside risk using a small set of readily available variables.
It does not replace current guideline-based STEMI care, and it does not decide cath timing, ICU duration, or mechanical-support use by itself.
Use the score as a compact prognostic summary tied to the original STEMI fibrinolysis framework, while keeping modern management decisions anchored in the broader clinical picture.

This page applies the original eight-variable TIMI STEMI score exactly as a bedside prognosis tool. It sums the age band, comorbidity, hemodynamic, Killip, body-weight, ECG-territory, and treatment-delay points into the standard 0-to-14 total and then displays the original 30-day mortality framework from the derivation cohort.
The page is intentionally framed as a prognostic summary rather than a reperfusion or ICU-order algorithm. The mortality percentages reflect the original fibrinolytic-era STEMI population and should not be treated as perfectly calibrated to every modern PCI-era setting.
It still works as a practical bedside prognostic summary, but the event percentages come from the original fibrinolytic-era cohort and should not be treated as perfectly calibrated to contemporary STEMI care.
They are different scores for different acute coronary syndrome settings. TIMI STEMI focuses on STEMI prognosis, while TIMI UA/NSTEMI uses a different 7-item framework and a different outcome model.
It is one of the strongest components because clinical heart-failure severity at presentation carries major prognostic weight in STEMI.
Low body weight was a significant predictor in the original derivation cohort and contributes to the total score for that reason.
Both are prognostic tools, but they are not interchangeable. TIMI STEMI is simpler and very bedside-friendly, while GRACE uses a different structure and broader ACS risk framework.
No. Reperfusion strategy should follow current STEMI guidelines and the actual clinical setting. The TIMI score is a prognostic aid, not a stand-alone management rule.
