Question 19 • VA_Pharmacology_A

Why are ACE inhibitors used to treat congestive heart failure?

Answer
A
They block the enzymes that cause vasoconstriction, thereby dilating blood vessels.
B
They block the enzymes that cause vasodilation, thereby constricting blood vessels.
C
They block the enzymes that produce cholesterol, thereby keeping the heart healthy.
D
They block the enzymes that inhibit calcium, thereby keeping the heart healthy.

Explanation

ACE inhibitors block angiotensin-converting enzyme, which reduces production of angiotensin II, a substance that narrows blood vessels. With less vasoconstriction, blood vessels dilate and the heart pumps against less resistance, easing its workload in congestive heart failure. Choice A describes this effect.
