A heart attack due to blockage of coronary arteries is called

• A. Angina
• B. Stroke
• C. Aneurysm
• D. Myocardial infarction

Answer: (D)

A heart attack from a blocked coronary artery is described as a myocardial infarction, with myocard- meaning heart muscle and infarction meaning tissue death due to lack of oxygen. When a coronary artery is blocked, part of the heart muscle is deprived of blood and dies, which is what infarction refers to. Angina is chest pain from reduced blood flow that doesn’t necessarily cause heart muscle death. A stroke involves blood flow problems in the brain, not the heart. An aneurysm is a bulging, weakened area of a vessel that can rupture, not the event of heart muscle death from a blocked coronary artery. So the precise term for this scenario is myocardial infarction.
