An echocardiographic assessment of cardiac functions and structure in children on dialysis

Area of Science:

• Pediatric Nephrology
• Cardiology
• Echocardiography

Background:

• Cardiovascular complications are a leading cause of mortality in end-stage renal disease.
• Chronic kidney disease (CKD) affects cardiac health in pediatric populations.
• Evaluating cardiac function is crucial for managing CKD patients.

Purpose of the Study:

• To assess systolic and diastolic cardiac functions in children with chronic renal disease.
• To compare cardiac function between children on different renal replacement therapies and healthy controls.

Main Methods:

• Echocardiography was used to examine 25 children on renal replacement therapy (peritoneal dialysis or hemodialysis), 10 children with chronic renal insufficiency, and 27 healthy controls.
• Systolic and diastolic parameters, including left ventricular mass index and diastolic flow velocities, were analyzed.

Main Results:

• No significant differences in systolic function were observed between patient groups and controls.
• Left ventricular mass index was significantly higher in both hemodialysis and peritoneal dialysis patients compared to controls.
• Diastolic function was impaired in dialysis patients, evidenced by higher peak late diastolic flow velocity (A) and lower E/A ratios compared to controls.

Conclusions:

• Diastolic cardiac function is impaired in children undergoing both peritoneal dialysis and hemodialysis.
• Peritoneal dialysis does not appear to offer an advantage over hemodialysis in preserving diastolic cardiac function.
• Further research with larger cohorts is needed to determine the long-term cardiac effects of different dialysis modalities in children.
