Non-ST-segment elevation myocardial infarction (NSTEMI)

Non-ST-segment elevation myocardial infarction (NSTEMI) is a type of heart attack caused by reduced blood flow to the heart muscle, leading to damage. Unlike some heart attacks, it doesn't show the typical changes on an ECG, but blood tests reveal heart muscle injury. It often results from a partially blocked coronary artery, which can cause chest pain, shortness of breath, or discomfort. Prompt medical attention is essential to restore blood flow, prevent further damage, and reduce the risk of future heart problems. Treatment may include medications, lifestyle changes, and sometimes procedures to open blocked arteries.
