title: [Effect of hemodialysis on hemodynamic assessment and cardiac flows determined by Doppler echocardiography].
abstract: 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.
