Myocardial Infarction
Myocardial infarction, commonly known as a heart attack, is a severe medical emergency resulting from prolonged myocardial ischemia, leading to irreversible necrosis of heart muscle tissue. This typically occurs due to an acute occlusion of a coronary artery, often caused by the rupture of an atherosclerotic plaque and subsequent thrombus formation. Immediate medical intervention is crucial to limit heart damage and improve patient outcomes.
