DETERMINATION OF INDICATORS OF DIASTOLIC DYSFUNCTION OF THE RIGHT VENTRICLE IN PATIENTS WITH HYPERTENSION

Аннотация

Hypertension is currently one of the most urgent medical problems. This is largely due to the fact that arterial hypertension, which largely determines the high cardiovascular morbidity, disability and mortality, is also characterized by a wide prevalence. Early diagnosis of changes in the heart in hypertensive patients is of great practical interest, which allows timely preventive measures and treatment. As a rule, with arterial hypertension, the left ventricle is primarily and to a greater extent affected, since the main load falls on it from the very beginning of the disease. An analysis was made of the parameters of the diastolic function of the right ventricle depending on the level of rise in diastolic blood pressure between patients with mild and high arterial hypertension. At the same time, significant differences were revealed, which concerned the ratio of the maximum filling rate to the maximum ejection rate. There was a trend towards an increase in the time of the fast filling phase of the contribution of the fast filling phase to the diastole of the right ventricle, which is due to the initial signs of diastolic dysfunction of the right ventricle with a decrease in the maximum filling rate and a moderate increase in the contribution of the right atrial systole to the filling of the right ventricle.
