Diastolic Function of the Left and Right Ventricles of the Heart in
Outpatients with Arterial Hypertension
Abstract
The aim of the study is to investigate the impairment of diastolic
function of the left ventricle (LV) and the right ventricle (RV) in
arterial hypertension outpatients. Materials and methods. Arterial
hypertension patients (n=299) and practically healthy people (n=62) were
examined on an outpatient basis. Echocardiographically, diastolic
dysfunctions of both ventricles were evaluated. Results. All the
arterial hypertension patients had a pattern of diastolic dysfunction
(DD) of the RV of different grades (grade I RVDD and grade II RVDD),
regardless of the presence or absence of pulmonary arterial
hypertension. Patterns of grade I LVDD and grade I RVDD were detected in
84 patients. Patterns of grade I LVDD and grade II RVDD were detected in
77 patients. Patterns of grade II LVDD and grade II RVDD were detected
in 41 patients. A pattern of grade II RVDD with normal left ventricular
diastolic function was detected in 97 patients with a short duration of
disease (3.92±0.48 years) versus the other groups with more than 15
years of hypertension. 175 arterial hypertension patients had grade I or
II LVDD only in 18.3% of cases according to the recommendations of the
American and European societies of echocardiographers (2016).
Conclusion. The patients with a short period of hypertensive disease
have only the pseudonormal pattern of RVDD, which can be an early
diagnostic marker of heart failure. Echocardiographic diagnosis of
diastolic function made according to various criteria can both increase
the number of chronic heart failure patients and significantly decrease
it.
