To evaluate the effects of left ventricular preload on left ventricular diastolic behavior, M-mode and pulsed wave Doppler echocardiography were preformed in 18 patients with chronic renal failure before and after hemodialysis. After hemodialysis with about 3.2 l volume loss, systemic blood pressure and heart rate did not change significantly. Hemodialysis diminished maximal left atrial dimension from 35±5 to 31±5 mm (p
