Diastolic heart dysfunction occurs essentially in patients who suffer from chronic heart failure. In this context an investigation and application of different methods for diastolic function improvement remain a priority in the therapy (IVRT decreasing; p =0,046), but an active myocardium relaxation turned for the better (increasing of Е/А (p <0,001) by component А lowering (p =0,003). Changes of pulmonary veins parameters were followed by the improvement of left heart ventricle relaxation p =0,051; p =0,028. Patients with myocardial infarction in anamnesis had an IVRT decreasing (p =0,040) and А decreasing (p =0,041). In addition, in this group left atrial function improved (PVS decreasing; p =0,037 (Для цитирования: Хлопина И.А., Шацова Е.Н., Лупачев В.В., Плакуев А.Н., Чернозёмова А.В.3, Кубасов Р.В.
