NSTEMI

Also written as: NSTEMI — Non-ST-elevation myocardial infarction

Non-ST-elevation myocardial infarction, a type of heart attack diagnosed without characteristic ST-segment elevation on ECG.

Full Definition

Non-ST-elevation myocardial infarction (NSTEMI) is a form of acute coronary syndrome where cardiac biomarkers indicate myocardial necrosis but the electrocardiogram does not show ST-segment elevation. In cardiovascular research manuscripts, NSTEMI is often contrasted with STEMI in patient population descriptions and outcome analyses. Editors must ensure consistent capitalization and proper distinction from unstable angina in clinical trial reports.

Usage

Usage note: Always capitalize all letters. Distinguish clearly from STEMI and unstable angina in research contexts.
