How does an angiotensin-converting enzyme inhibitor function?
a. blunts node conduction resulting in lower ventricular response
b. reduces blood pressure and causes water loss through increased urine production
c. lowers blood pressure and controls ventricular arrhythmias
d. reduces myocardial oxygen demand and reduces blood pressure
Answer: d. reduces myocardial oxygen demand and reduces blood pressure
An angiotension-converting enzyme inhibitor functions by reducing myocardial oxygen demand and blood pressure. This is thought to increase exercise tolerance in patients with left ventricular dysfunction.
