ST elevation myocardial infarction (STEMI)

ST-elevation myocardial infarction (STEMI) is a severe type of heart attack that occurs when blood flow to a part of the heart is blocked for a prolonged period. This blockage usually happens due to a blood clot in a coronary artery, leading to damage or death of heart muscle. In an ECG (electrocardiogram), STEMI is characterized by a specific elevation in the ST segment, indicating acute injury to the heart. Timely medical intervention, such as medication or procedures to restore blood flow, is crucial to minimize heart damage and improve survival chances.
