non-ST elevation myocardial infarction (NSTEMI)

Non-ST elevation myocardial infarction (NSTEMI) is a type of heart attack that occurs when blood flow to the heart is partially blocked, causing damage to the heart muscle. Unlike a complete blockage seen in ST-elevation myocardial infarction (STEMI), NSTEMI does not show a specific pattern on an electrocardiogram (ECG). Patients may experience chest pain, shortness of breath, or other symptoms. Diagnosis is typically confirmed with blood tests that detect heart proteins. Treatment often involves medication and sometimes procedures like angioplasty to improve blood flow and prevent further heart damage. Prompt medical attention is crucial.
