NSTEMI stands for which of the following?

NSTEMI stands for Non-ST segment elevation myocardial infarction. This term is used to describe a type of heart attack that occurs when there is a partial blockage of blood flow to the heart muscle, leading to damage but not complete occlusion. The distinguishing feature of NSTEMI is that it does not show the characteristic ST segment elevation on an electrocardiogram (ECG) that is associated with other types of heart attacks, such as STEMI (ST-elevation myocardial infarction). Instead, patients may present with symptoms such as chest pain or discomfort, and diagnostic tests, including troponin levels, help confirm myocardial injury. Understanding the terminology is crucial for effective communication and management in emergency medical settings.
