Abstract
This noninvasive echocardiographic study of cardiac performance in 27 patients with chronic renal failure and vascular access documented the magnitude of forward cardiac output to be 65% of the observed index. Hemodialysis resulted in acute hemodynamic changes, including an average fall in the cardiac index of 57%, presumably because of a 40% decrease in left ventricular filling volume. Ventricular function was suboptimal 3 mo. post-transplant, as reflected by a continued low cardiac index and depressed ejection fraction, although the general reduction in cardiac index and diastolic volume on postoperative day 7 was of the magnitude expected from arteriovenous access occlusion.
