Comparison of the effects of long-term hemodialysis and peritoneal dialysis modalities on left ventricular functions

Abstract

Background: Hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD) affect left ventricular hemodynamics. This study compared the effect of two treatment modalities, CAPD and HD, on left ventricular systolic and diastolic functions in maintenance dialysis patients.Methods: A total of 47 patients (24 CAPD and 23 HD) undergoing long-term dialysis were included in the study. Left ventricular functions, left ventricular hypertrophy, and left ventricular geometry were evaluated using echocardiography.Results: The mean age of the patients was 58.6 +/- 11.2 years. The mean dialysis time was 125.1 +/- 35.2 months. When echocardiographic parameters were examined, left ventricular muscle mass, mass index, E/e' ratios, and global longitudinal strain were significantly higher in the CAPD group. The rates of diastolic dysfunction (66.7% vs. 26.1%) and left ventricular hypertrophy (91.7% vs. 60.9%) were higher in the CAPD group than in the HD group. Dialysis modality CAPD, abnormal global longitudinal strain (GLS), and increased serum calcium were associated with an increased risk of diastolic dysfunction.Conclusions: The study results demonstrated that left ventricle (LV) diastolic dysfunction and deterioration in left ventricular geometry were significantly higher in patients receiving long-term CAPD treatment than for long-term HD treatment.
