Abstract
▪ Abstract
The loss of myocytes as a consequence of myocardial infarction results in a prompt reduction in regional wall motion and often leads to more protracted and progressive changes in ventricular architecture. The recognition that the process of ventricular enlargement following myocardial infarction is modifiable provided the initial rationale for the use of angiotensin-converting enzyme (ACE) inhibitors as therapy to prevent deterioration in ventricular size and function following infarction. Experimental and clinical studies have documented the effectiveness of this therapy in preventing this late enlargement following infarction. Increasing clinical evidence indicates that this new use of ACE inhibitor therapy in survivors of acute myocardial infarction will lead to an improvement in clinical outcome.
