Beneficial effects of angiotensin-converting enzyme inhibitor and nitrate association on left ventricular remodeling in patients with large acute myocardial infarction: the Delapril Remodeling after Acute Myocardial Infarction (DRAMI) trial.

Background: In the large-scale trial, Gruppo Italiano per lo Studio della Sopravvivenza nell'Infarto Miocardico-3 (GISSI-3), patients receiving the combination of lisinopril and glyceryl trinitrate benefited most from experimental therapy. Therefore, a multicenter, randomized, double-blind study, Delapril Remodeling After Acute Myocardial Infarction (DRAMI), was designed to assess (1) the possible additive beneficial effect on left ventricular remodeling of nitrates when combined with an angiotensin-converting enzyme inhibitor (ACEI), and (2) the tolerability of a new ACEI, delapril, in respect to lisinopril in patients with large myocardial infarction (MI).

Methods: A total of 177 patients were randomized to receive delapril plus isosorbide-5-mononitrate (IS5MN) placebo, delapril plus IS5MN, lisinopril plus IS5MN placebo, or lisinopril plus IS5MN starting within the first 36 hours after the onset of symptoms and continuing for 3 months.
