title: [Converting enzyme inhibitors and coronary failure].
abstract: Nearly 15 years ago, it has been shown that myocardial infarction is accompanied by left ventricular dilatation. In the following years more details were obtained on morphological changes consecutive to myocardial infarction, now grouped together under the term left ventricular remodelling. These changes enable the patients to survive despite reduction of the contractile ventricular mass, but they expose the ventricles to constraints resulting in excessive work load. It has been shown that these changes can be reduced by early myocardial reperfusion and by administration of angiotensin-converting enzyme (ACE) inhibitors. These findings were established first in animals, then in man. Administering ACE inhibitors to patients with symptomatic heart failure consecutive to advanced ischaemic cardiopathy prolongs the patients' survival. When ACE inhibitors are given to patients with severe asymptomatic left ventricular dysfunction which started soon or long after a myocardial infarction, they reduce the frequency of ischaemic events, passage to symptomatic heart failure and, at least in one study, mortality. ACE inhibitors have also been shown to reduce the size of myocardial necrosis when administered in the acute phase of experimental myocardial infarction. Preliminary data have demonstrated that ACE inhibitors given in the acute phase of myocardial infarction reduce the left ventricular dilatation which follows infarction. However, a study of ACE inhibitors administered to a large number of patients in the acute phase of myocardial infarction had to be interrupted because of the over-mortality in the treated group. These facts are reviewed in this article, and attempts have been made at deducing from them the current indications of ACE inhibitors in patients with coronary heart disease.
