The research objective was to analyze a structurally functional condition of the right ventricle of patients with chronic heart failure. All 57 patients underwent an echocardiography. The received results allow to draw a conclusion that structural and functional processes of remodeling of the right ventricle with its global dysfunction, accrue with an overload of a small circle of blood circulation: from passive venous post-capillary pulmonary hypertension up to the development of jet hypertension against high pulmonary vascular resistance.
