| Abstract: | The aim of the study was to evaluate efficiency of isosorbide-5-mononitrate (IMN) retard (40 to 80 mg/day) in 33 patients older than 60 with stable angina pectoris (functional class III-IV). The study shows that IMN is an effective and safe antianginal agent in treatment of patients with stable angina: it decreased the frequency of anginal attacks (from 4.1 +/- 0.34 to 0.8 +/- 0.13 per day, p < 0.0001), and additional nitroglycerin intake (from 2.2 +/- 0.32 to 0.2 +/- 0.05 tablets per day, p < 0.0001); according to the results of 24-hour ECG monitoring, it reduced ST-segment depression (from 2.2 +/- 0.17 to 0.9 +/- 0.09, p < 0.0001), preventing episodes of painful and silent myocardial ischemia (from 3.5 +/- 0.37 to 2.1 +/- 0.31, p < 0.0001); increased life quality as demonstrated by evaluation of physical (from 19.7 +/- 2.2 to 45.7 +/- 2.22, p < 0.0001), and mental (from 30.9 +/- 2.67 to 57.5 +/- 2.67, p < 0.0001) components using MOS-SF 36 questionnaire. Adverse effects of the drug (headache and hypotension) were observed in 6 (16.6%) patients. |
