The Effect of Hemodialysis on the Echocardiographic Indexes of Left Ventricular Diastolic Function in Chronic Renal Failure

20 patients (15 men, 5 women, average age 50±14, range 19-69 years) with chronic renal failure and normal left ventricular systolic function (LVEF ≥50%) on maintenance hemodialysis. Excluded: coronary artery disease, congenital heart disease, valvular disease, moderate or severe pericardial effusion, arrhythmias, pulmonary congestion, or lower extremity edema.
