[Comparative study of the therapeutic effect of antiangina agents]

The therapeutic effect of obsidan (25 to 250 mg/24 h), cordanum (75 to 300 mg/24 h), nitropenton (30 mg/24 h), combination of obsidan with nitropenton, prenylamin (180 mg/24 h), stenopril (180 mg/24 h), cordaron (600 mg/24h) and corvaton (4 mg/24 h) was studied according to clinical asessment in 127 patients with stenocardia and in 44 of them by loading tests (veloergometry or treadmill). According to the clinical assessment -- very good (abating of stenocardia paroxysms) and good effect (less frequent paroxysms nitroglycerin necessary every one-two days) was established in 82 per cent of those treated with obsidan, in 78 per cent of the treated with cordanum, in 86 per cent of those treated with the combination obsidan with nitropenton, in 44 per cent of the treated with nitropenton, in 42 per cent of the treated with prenylamin, in 46 per cent pf the treated with stenopril, in 7 out of 9 patients treated with cordaron as well as in 7 out of 9 patients treated with corvaton. According to the data from the loading tests--very good (increase of capacity, not limited by pain and ST depression) and good effect (considerable increase of capacity but limited by pain and ST depression) was found in 77 per cent of the patients administered obsidan, in 67 per cent of those administered cardanum and in 33 per cent of the patients administered tenopril and prenylamin. Beta--blockers significantly excel the therapeutic effect of stenopril, prenylanin and nitropenton, both according to clinical assessment (P < 0,02 to p < 0,001) and to the data from the loading tests (P < 0,02). Beta-blockers dosage was individually determined but 80 per cent of the patients with a favourable effect by obsidan or cordanum had received 60-120 mg/24 h and 150 mg/24 h respectively. The individual effect of the patients is presented so that even the small number of cases observed with cordaron and corvaton treatment shows it reasonable to include new preparations in antianginose treatment.
