Which term describes an acute episode of heart disease marked by death or damage of heart muscle due to insufficient blood supply, usually as a result of coronary thrombosis or occlusion?

• A. Myocardial Infarction
• B. Heart Disease
• C. Stroke
• D. Metabolic Syndrome

Answer: (A)

An acute episode of heart disease marked by death or damage of heart muscle due to insufficient blood supply is myocardial infarction. It happens when a coronary artery becomes blocked, usually by a thrombus forming on a ruptured atherosclerotic plaque, cutting off oxygen-rich blood to a region of the heart. If blood flow is stopped long enough, heart muscle cells die, producing tissue death—the infarct. Other terms don’t fit this specific event: heart disease is a broad umbrella for various heart conditions; stroke refers to brain ischemia; metabolic syndrome is a cluster of metabolic risk factors that raise cardiovascular risk but does not describe a specific myocardial event.
