Effects of CAPD on Cardiac Function in Patients with End-Stage Renal Disease: in Comparison with Hemodialysis

ABSTRACT

To investigate long term effects of CAPD on the left ventricular function in end-stage renal disease patients, M-mode echocardiographic studies and measurement o fsystolic time intervals were performed in 20 CAPD cases, 28 hemodialysis cases and 29 uremic controls. Compared to the uremic control grup, the patients on CAPD treatment revealed significant improvement of ventricular contractility and reduction of volume. On the other hand in hemodialysis group, even though there was improvement of ventricular contractility, volume control was not adequate. In the systolic time interval measurement, it is postulated that increase of PEP/LVET ratio in CAPD group probably results from reduction of volume(preload) rather than from deranged ventricular function.
