[Vasodilator treatment of chronic heart failure: a chronic double-blind trial with prazosin and erythrityl tetranitrate].

| Abstract |
A chronic double-blind experiment was carried out with 32 patients with severe chronic stasis cardiac insufficiency, with concomitant idiopathic congestive cardiomyopathy and ischemic heart disease, in assessing the effect of vasodilators prazosin or erythrityl tetranitrate upon the decompensation symptomatics and hemodynamic indices. The clinical indices of cardiac insufficiency with hemodynamic signs of pre-loading, myocardial contractility and postloading of left ventricle were followed up. Besides vasodilators the patients were administered the ordinary maintenance therapy with digoxin and diuretics. The experiment was a double blind one, controlled by placebo-periods and covered a 6 months follow-up period. The combined venous-arteriolar vasodilator prazosin was reduced pre and post-loading, it increased the cardiac output, without essential changes in functional capacity of the patients with chronic cardiac insufficiency. Erythrityl tetranitrate, however, has no substantial effect on the clinical and hemodynamic indices of statis cardiac insufficiency even in higher doses. That suggests the necessity of the chronic cardiac insufficiency treatment to be carried out with vasodilators with venous and arteriolar effect.
