The influence of adrenoreactive preparations on clinical and haemodynamic parameters in patients with ischaemic heart disease.

The influence of anaprilin, oxprenolol, nonachlazine, prazosin and levodopa on the clinical course and haemodynamics was investigated in 138 patients with ischaemic heart disease in whom selective coronary angiography had revealed an up to 50 percent stenosis of one of coronary arteries. The clinical picture of IHD patients with a high tolerance of physical exercise was characterized by a preponderance of spontaneous angina pectoris accompanied by painless myocardial ischaemia. A certain role in the genesis of these disturbances is played by the relative increase in the activity of alpha 1-adrenoreceptors and decrease in beta-adrenoreceptor activity. Prazosin and nonachlazine in monotherapy reduced the number of anginal attacks and episodes of painless myocardial ischaemia.

[Cardiohemodynamics and microcirculation in patients with ischemic heart disease undergoing beta-adrenergic receptor stimulation and blockade].

A study of 76 patients with ischemic heart disease is presented who revealed during coronography stenosis of one-three coronary arteries equalling 50-75% of the vessel lumen. Analysis of the effect of anaprilin and nonachlazin on the clinical course and hemodynamics revealed that in patients with initial coronary atherosclerosis of middle age beta-adrenodependent vasodilation of the coronary arteries decreased. In these patients anaprilin may increase the frequency of attacks of spontaneous stenocardia. On the contrary, nonachlazin reduces manifestations of stenocardia but it may be used only in patients with a high tolerance to physical load.
