[Comparison of the clinical and hemodynamic effects of nitroglycerin, isosorbide dinitrate and isosorbide-5-mononitrate in acute myocardial infarction].

One hundred and eighty patients with acute myocardial infarction (MI) were followed up. The patients were divided into 3 groups: (1) those receiving glyceryl trinitrate (GTN) (n = 43); (2) those on isosorbide dinitrate (ISDN) (n = 66); (3) those on isosorbide-5-mononitrate (IS-5-MN) (n = 71). In all the groups, the drugs were given by long-term continuous oligovolumic infusion. Following 24 hours of administration, 66.7, 47.3, and 17.1% increases in infusion rates were required in 74.4, 72.7, and 26.8% of the patients from Groups 1, 2, and 3, respectively. All the agents produced a pronounced antianginal effect and resulted in alleviated acute left ventricular failure. The in-hospital mortality rates were 16.2, 16.7, and 12.7% in Groups 1, 2, and 3, respectively. GTN, ISDN, and IS-5-MN caused adverse effects in 4.7, 18.2, and 2.8% of the patients from Groups 1, 2, and 3, respectively.
