A myocardial infarction is known as a

• A. Stroke
• B. Aneurysm
• C. Heart attack
• D. Angina

Answer: (C)

A myocardial infarction is the event where heart muscle tissue dies because its blood supply is blocked. The common name for this situation is a heart attack, which is why this option best fits.

Stroke refers to brain injury from interrupted blood flow, not the heart. An aneurysm is a bulging, weakened area in a blood vessel that can rupture, which is a different vascular issue. Angina is chest pain from temporary heart muscle ischemia without tissue death, whereas a myocardial infarction involves actual death of heart muscle due to prolonged blockage.
