Hypertension and heart disease.

A. Elevated blood levels of aldosterone and renin resulting from an atherosclerotic plaque in a renal artery.

B. Hyperprolactinemia due to a pituitary tumor.

C. Acromegaly due to a GH-producing tumor that developed in adulthood.

D. Cushing syndrome due to an adrenal tumor.

Correct Answer: Elevated blood levels of aldosterone and renin resulting from an atherosclerotic plaque in a renal artery.

Description: The plaque in the renal artery causes the release of renin, which elevates aldosterone, thus raising blood pressure. Atherosclerotic plaques are also probably the cause of the heart disease. PRL (milk production), GH, or cortisol release will not lead to hypertension and heart disease.
