25 patients with end-stage renal failure were studied by different echocardiographic techniques before and immediately after hemodialysis using M-mode, 2-dimensional and Doppler echocardiography. Preload reduction after dialysis was manifested by a decrease in body weight, in left atrial diameter and in the left ventricular end-diastolic dimension. Doppler flow patterns immediately after dialysis showed reduction in early diastolic velocities across the atrioventricular valves and increase in the flow velocities across the semilunar valves and the peripheral A-V fistula. The flow velocity integral, calculated by Doppler echocardiography, was lower after dialysis. Significant improvement in left ventricular myocardial function after dialysis was correlated with reduction in afterload and increase in myocardial contractility.
采用M型、二维及多普勒超声心动图技术，对25例终末期肾衰竭患者在血液透析前及透析后即刻进行了研究。透析后前负荷降低表现为体重、左心房内径及左心室舒张末期内径减小。透析后即刻的多普勒血流模式显示，房室瓣舒张早期速度降低，半月瓣及外周动静脉瘘处血流速度增加。通过多普勒超声心动图计算的流速积分在透析后降低。透析后左心室心肌功能的显著改善与后负荷降低及心肌收缩力增加相关。
