Question 1 of 5
The primary aim of angiotensin converting enzyme inhibitor (ACE-I) therapy in the treatment of congestive heart failure is to improve which physiological parameter?
Correct Answer: A
Rationale: ACE inhibitors in congestive heart failure primarily reduce afterload (Choice A) by blocking angiotensin II, leading to vasodilation, decreased systemic vascular resistance, and reduced cardiac workload, improving cardiac output. Contractility (Choice B) isn’t directly enhanced. Heart rate (Choice C) may decrease indirectly but isn’t the primary aim. Myocardial relaxation (Choice D) relates more to diastolic function, not the main effect. Afterload reduction is the key mechanism.
