[Converting enzyme inhibitors in acute myocardial infarct and heart failure]

Inhibitors of angiotensin converting enzyme (ACE inhibitors) have been introduced more than fifteen years ago into the treatment of hypertension, congestive heart failure, myocardial infarction and diabetic nephropathy. The therapeutic success is related to their action in reduction of plasma and tissue angiotensin II concentrations and potentiation of endogenous kinins. They are able to improve myocardium metabolic status, prevent cardiac hypertrophy, limit myocardial infarct size, and thus prevent heart failure. Since 1987 ACE inhibitors are introduced in the clinical practice in our clinic. We introduced the therapy with lisinopril (Lopril), in 70% of patients among 2855 patients that were admitted in Coronary Care Unit in 1997 and 1998. Lisinopril was introduced as soon as the patient was admitted, together with fibrinolitic, Heparin and Aspirin therapy. Since that time we noticed decrease in postinfarction heart failure in comparison to previous years. We recommend permanent therapy with a small doses of ACE inhibitors in patients with heart infarction.
