Comparison of the Effects of Dialysis Type on Right Heart Functions in Chronic Renal Failure Patients

Abstract

Aim: The aim of this study was to compare the effects of dialysis type on right heart functions with two-dimensional speckle tracking echocardiography (2D-STE). Material and Methods: A total of 53 patients who have peritoneal dialysis and hemodialysis, applied to cardiology and nephrology outpatient clinics, were included in the study. Those with left heart failure, coronary artery disease, primary and secondary pulmonary hypertension, pulmonary embolism, deep vein thrombosis, moderate and severe heart valve failure and stenosis were excluded from the study. Sociodemographic characteristics and biochemical parameters of the patients were recorded. Right heart functions of the patients were evaluated using 2D-STE. Results: There was no difference between groups with respect to age (p=0.496), the rate of male was higher in hemodialysis group (p=0.006). In comparison of 2D-STE measurements; right atrium (RA) maximum volume and RA minimum volume were significantly higher in hemodialysis patients (p=0.006, p=0.007, respectively). There were no difference between the groups in RA maximum volume index, RA minimum volume index and tricuspid annular plane systolic excursion (TAPSE). RAS strain and RAA strain were significantly lower in hemodialysis patients (p=0.001, p=0.012, respectively). A positive correlation was found between TAPSE and RA maximum volume in hemodialysis patients (r=0.484, p=0.036), and between TAPSE and RA minimum volume in peritoneal dialysis patients (r=0.486, p=0.025). Conclusion: Right ventricular functions were found to be similar in peritoneal dialysis and hemodialysis patients. It was observed that right atrial functions were better protected in peritoneal dialysis patients than hemodialysis patients.
