Abstract:
To evaluate the right ventricular systolic function in uremia patients and the effects of maintenance hemodialysis on right ventricular systolic function by volume and strain parameters obtained by 4D RV Volume . Methods Seventy‐six patients with uremia and twenty‐two controls were selected . According to left ventricular ejection fraction ( LVEF) ,uremia patients were divided into normal LVEF uremia group and decreased LVEF uremia group . T hen normal LVEF uremia group was divided into maintenance hemodialysis group and non‐dialysis group . Conventional ultrasound parameters included :LVEF ,pulmonary artery systolic pressure ( PASP) and tricuspid annular plane systolic excursion ( T APSE‐2D) . 4D RV Volume parameters included : right ventricular end‐diastolic volume ( RVEDV ) , tricuspid annular plane systolic excursion ( T APSE‐4D ) ,right ventricular area change rate ( FAC ) ,right ventricular ejection fraction ( RVEF) and right ventricular free wall longitudinal systolic strain ( RV‐GLSfree ) . Results①Compared with the control group ,T APSE‐2D decreased significantly in the decreased LVEF uremia group ( P ＜0 .05) ,w hile there was no significant difference of T APSE‐2D in normal LVEF uremia group ( P ＞ 0 .05) . Compared with the control group and normal LVEF uremia group ,PASP increased significantly in the decreased LVEF uremia group ( P ＜ 0 .05 ) . Compared with the control group ,RVEDV increased significantly both in the normal LVEF and decreased LVEF uremia group ,w hich showed an increasing trend in these three groups ( P ＜0 .05) ,while T APSE‐4D ,FAC ,RVEF and RV‐GLSfree all decreased significantly and showed a decreasing trend in these three groups ( P ＜ 0 .05 ) . ② Compared with the control group , T APSE‐2D decreased significantly in non‐dialysis group ( P ＜0 .05) ,but there was no significant difference in uremia hemodialysis group ( P ＞0 .05) . Compared with the control group ,PASP and RVEDV increased and T APSE‐4D ,FAC ,RVEF and RV‐GLSfree decreased significantly in uremia hemodialysis group and non‐dialysis group ( P ＜ 0 .05 ) . Compared with non‐dialysis group , T APSE‐2D and T APSE‐4D increased significantly in hemodialysis group ( P ＜0 .05) ,while there was no significant difference in RVEDV ,FAC , RVEF and RV‐GLSfree in uremia hemodialysis group ( P ＞0 .05) . Conclusions 4D RV Volume could early and accurately evaluate the right ventricular systolic dysfunction in uremia patients . Furthermore ,w hen evaluating right ventricular systolic function in uremia patients treated with maintenance hemodialysis , indices such as right ventricular strain and volume parameters should be comprehensively considered .
