[Myocardial contractile function in Itsenko-Cushing disease].

The method of acceleration cinecardiography was applied to the study of phasic structure of the systole of the left and right cardiac ventricles in 22 patients suffering from Itsenko-Cushing's disease. In the majority of patients with severe and prolonged (over 5-year duration) sickness changes in the duration of the systolic phases of both cardiac ventricles were characteristic of phasic hypodynamia syndrome, i.e. there was a reduction of the contractile activity of the myocardium. In 6 patients with marked arterial hypertension the structure of the left ventricle systole testified to the presence of a phasic syndrome of high systolic pressure. Intensification of cardiac contraction (phasic hyperdynamia syndrome) was less frequent. This chiefly occurred in case of mild course of the disease of less than 5 years duration.
