Mr. Lopez has been advised to watch his cholesterol intake to prevent a myocardial infarction. Which describes the relationship between cholesterol and myocardial infarction?

Answer

A high cholesterol diet will increase cholesterol. Cholesterol reduces the occurence of thromboses. Thromboses obstruct the flow in coronary arteries.

A low cholesterol diet will reduce cholesterol. Cholesterol is strongly attracted to plaque. Plaque can build up and block the coronary arteries.

A high cholesterol diet will increase cholesterol. Cholesterol is a key ingredient in reducing the formation of plaque. Plaque can build up and block the coronary arteries.

A low cholesterol diet will reduce cholesterol. Cholesterol is one of the main components in thromboses. Thromboses obstruct the flow or blood in coronary arteries.

Explanation

A low-cholesterol diet can help reduce cholesterol levels in the blood. Excess cholesterol can contribute to plaque buildup in artery walls, narrowing or blocking the coronary arteries and potentially causing a myocardial infarction. Choice B is the best description; cholesterol does not reduce plaque formation as choice C claims.
