Doppler Echocardiography Assessment of Right Ventricular Filling Dynamics in Essential Hypertension / 中华超声影像学杂志

ABSTRACT

In order to determine whether alteration in right ventricular filling dynamics Occurs in hypertension and compare the filling dynamics of RV and LV pulsed Doppler echocardiographic studes were performed with sample volumes at the tricuspid and mitral anuli in 51 hypertensive patients and 50 normotensive volunteers.Comparing with the normotensives,in hypertensive patients,RV early filling velocity(46±7 vs 41±6,P<O.05),1/2FF(61±10 vs 55±7,P<O.01)and 1/3FF(52±12 vs 44±8, P<0.01)were lower;ration of A/E(0.8±0.2 vs 1.0±0.4,P<O.05)and AFF(24±9 vs 39±14,P <0.01)were higher.LV filling parameters showed similar changes.RV filling dynamics were closely related to LV filling dynamics in both hypertensive patients(r=0.59～0.87,P<0.01)and normotensive individuals(r=0.65～0.90,P<0.01).However,no correlations were found between filling dynamics and LVM,LV posterior wall thickness.RV anterior thickness,blood pressure. concluded that RV filling dynamics are abnormal in hypertension,independent of LVM or blood pressure,and are closely related tO LV filling dynamics.
