Question

Which of the following would be the most likely reason that atherosclerotic plaque would be responsible for producing a myocardial infarction?

Quizplus · Accepted Answer

A myocardial infarction occurs when a portion of the heart muscle is deprived of oxygen and nutrients due to a blockage in the coronary artery. Atherosclerotic plaque buildup can cause a blockage, preventing blood from reaching the myocardium. Therefore, Option D is the most likely reason for atherosclerotic plaque to be responsible for producing a myocardial infarction. Option A is incorrect because atherosclerotic plaque buildup generally occurs in arteries, not on the endocardium. Option B is incorrect because a 50% narrowing of the coronary arteries may not necessarily lead to a myocardial infarction, as other factors such as collateral circulation can compensate for the reduced blood flow. Option C is also incorrect because it is unlikely to cause a myocardial infarction, although it may contribute to chronic angina or other heart conditions.
