The increasing trend to the growth of cases of ischaemic cardiac disease and, first of all, cases of a stable stenocardia of tension and lethal outcome make topical the search of new effective etiopathogenic means for prophylaxis and treatment of this pathology. The goal of this investigation was to study effectiveness of treatment with selenium electrophoresis of patients with ICD:SST of the I-II functional classes (FC). Total of 76 patients with ischaemic cardiac disease have been investigated. Among them a stable stenocardia of tension of the I functional class was observed in 31 patients and SST of the second II FC - in 45 patients. It has been established that in patients with a stable stenocardia of tension the treatment with selenium electrophoresis evokes a slackening right up to absence of complaints; has a normalizing action on cardio-hemodynamics; improves oxygen provision of the organism increasing saturation of arterial and venous blood with oxygen; increases tolerance to physical loading and volume of fulfilled work; decreases changes in frequency of systole and arterial pressure under the influence of physical loading and restitution. Mentioned shifts decreased according to intensification of the pathology. The treatment had a positive action on all patients with SST of the I FC and 41 patients with a stable stenocardia of tension of the II FC. The treatment was inefficient in 4 patients with SST of the II FC.
