BACKGROUND/AIMS: Fluid overload is an important factor causing cardiovascular complications in dialysis patients. We compared fluid status, blood pressure (BP) and heart function between peritoneal dialysis (PD) patients and hemodialysis (HD) patients.
METHODS: We recruited 94 PD and 75 HD patients in our hospital. Fluid status was assessed by bioimpedance spectroscopy. Home BP was recorded. Use of antihypertensives was retrieved by chart review. In each group, 39 patients received echocardiographic examinations.
RESULTS: PD patients' fluid status was similar to that of predialysis HD patients. PD patients had lower systolic BP. E/E' and left ventricular mass index (LVMI) showed no significant intergroup difference. In multiple linear regression analyses, overhydration (OH)/extracellular water ratio >0.15 was associated with higher systolic BP, E/E' and LVMI.
CONCLUSIONS: While PD was associated with higher OH but non-inferior BP control and heart function, OH was indeed related to poor BP control, diastolic dysfunction and left ventricular hypertrophy.
