The TIMI (Thrombolysis in Myocardial Infarction) score for Unstable Angina/Non-ST Elevation Myocardial Infarction (UA/NSTEMI) is a clinical tool used to stratify risk in patients presenting with chest pain suggestive of acute coronary syndrome. This scoring system applies specifically to patients with unstable angina or non-ST elevation myocardial infarction.

The TIMI score for UA/NSTEMI helps clinicians predict the likelihood of major adverse cardiac events (MACE) within a 14-day period following presentation. These events include all-cause mortality, new or recurrent myocardial infarction, or severe recurrent ischemia requiring urgent revascularization.

The score is calculated based on seven variables: age ≥65 years, at least three risk factors for coronary artery disease, prior coronary stenosis of ≥50%, ST-segment deviation on ECG at presentation, at least two anginal events in the prior 24 hours, use of aspirin in the past seven days, and elevated serum cardiac markers. Each variable is assigned 1 point, and the total score ranges from 0 to 7.

There are no specific exclusion criteria for the use of the TIMI score for UA/NSTEMI. However, it

TIMI score for unstable angina/non-ST elevation MI
