TIMI score (non-ST-elevation ACS)

Estimates the risk of death, new infarction or urgent revascularization within 14 days in unstable angina and non-ST-elevation myocardial infarction.

Method · Limits of application

TIMI UA/NSTEMI/Antman 2000: 7 factors 0–1, total 0–7; excludes TIMI STEMI

This TIMI version was developed in unstable angina and non-ST-elevation infarction for 14-day composite outcomes; it is not the TIMI version for STEMI. The factors have specific temporal and clinical definitions. Rates from historical trials do not determine individual risk or current treatment without corresponding assessment and guidelines.

Conditions of use

Check the population, units, inclusion and exclusion criteria, and version in the original source. A result alone does not establish a diagnosis, discharge decision or prescription.

Documented parameters

Age ≥ 65 years
≥ 3 risk factors for coronary artery disease
Known coronary stenosis ≥ 50%
Aspirin use in the last 7 days
≥ 2 angina episodes in 24 hours
ST deviation ≥ 0.5 mm
Elevated necrosis marker

3/3 reference cases checked. Numerical tests are not clinical validation.

Relationship with cancer research

General context — relationship to be defined

A resource for general clinical contexts. This edition does not assign a specific oncological relationship; selecting it for a study requires a justified question, population and purpose.
