Effect of Hemodialysis on Global and Regional Cardiac Function in Children With End-stage Renal Disease

Introduction. Changes in cardiac structure and function are common among patients with end-stage renal disease. The aim of this study was to evaluate the effect of hemodialysis on global and segmental cardiac function in children with end-stage renal disease. Materials and Methods. Fifty-two children with ESRD who were on long-term hemodialysis at Nemazee Hospital, Shiraz, were enrolled. They underwent echocardiography (M-mode, 2-dimensional, Doppler, and speckle echocardiography) 30 minutes prior to and after hemodialysis, and the values were compared. Results. The mean age of the patients was 13.00 ± 3.53 years. There was a significant reduction in left ventricular systolic and diastolic dimensions and volume (P < .001) and the E:A ratio after dialysis (P = .03). Global and longitudinal strain and strain rate showed no significant changes before and after hemodialysis. Conclusions. Hemodialysis with volume reduction decreases left ventricular volume but not regional strain and strain rate significantly in children. This study showed preload independency of speckle echocardiography in children.
