The article is devoted to investigation of the biomechanics of a heart and pulmonary circulation by means of computer apexcardiogram and rheography of a pulmonary artery in patients with diabetes mellitus type 1 and 2. The authors examined 60 diabetic patients and 40 healthy individuals. All respondents were divided into 3 groups: group 1 (control) were apparently healthy people, 2 – patients with type 1 diabetes, 3 – patients with type 2 diabetes. The study assessed the speed and power performance changes of intraventricular pressure, vascular resistance and pulmonary artery vessels resistance and duration of phases of a cardiac cycle and pulmonary circulation. Analysis of kinetic parameters of myocardial and pulmonary artery showed the common qualitative and quantitative changes of central hemodynamics and biomechanics of a heart and pulmonary circulation in patients with diabetes of both types. However, in case of type 2 diabetes these changes are more evident.
