NSTEMI
Pronunciation: N-STEM-ee
Also written as: NSTEMI — Non-ST-elevation myocardial infarction
Non-ST-elevation myocardial infarction, a type of heart attack without specific ECG changes, requiring precise editorial handling.
Full Definition
Non-ST-elevation myocardial infarction represents a form of acute coronary syndrome where cardiac biomarkers are elevated indicating myocardial necrosis, but without the characteristic ST-segment elevation on electrocardiogram. This distinction is clinically significant as it affects treatment algorithms and prognosis. Medical editors must understand that NSTEMI is part of the acute coronary syndrome spectrum and requires different management approaches compared to STEMI. The term appears frequently in emergency medicine, cardiology consultations, and discharge summaries.
Usage
Usage note: Always spell out on first use in formal documents; distinguish clearly from STEMI in clinical contexts.
