Comparison of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers in the primary prevention of myocardial infarction in hypertensive patients

Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers have slightly different mechanisms of action. As such, it has been hypothesized that these 2 classes of medications differ in their ability to prevent myocardial infarction. In the present case-control study, we found no difference between angiotensin-converting enzyme inhibitors and angiotensin receptor blockers in the primary prevention of nonfatal myocardial infarction among patients with hypertension.
