Materials and Methods: The study comprised 24 children undergoing hemodialysis more then six months. Conventional and tissue Doppler echocardiography was performed, NT-proBNP levels were measured before and after hemodialysis. Echocardiographic results were compared regard to hydration status which measured with body composition monitor and hypotension event during dialysis. Results: Myocardial performance indices which gained with tissue Doppler echo were high in 22 patient. Mitral E/A ratio significantly decreased after hemodialysis. NT-proBNP levels were high but no difference was determined after dialysis. Nine patient experienced hypotension but nonsignificant difference was detected regarding echocardiographic findings and NT-proBNP levels. Conclusion: Diastolic dysfunction is frequent in chronical renal failure. Tissue Doppler echocardiography and myocardial performance index supply a more proper evaluation of global and regional cardiac function in chronical renal failure due to less hydration affectability. NT-proBNP should be monitored for cardiac dysfunction in chronical renal failure. Body composition monitor should be used in children for setting the ultrafiltration volume.enginfo:eu-repo/semantics/openAccessBody composition monitorChronic kidney diseaseMyocardial performance indexTissue Doppler echocardiographyarticle43410151022000437951900034
