In patients undergoing chronic dialysis, several factors appear to influence the occurrence of cardiac abnormalities. The aim of our study was to evaluate the effects of two different methods of renal replacement therapy (chronic haemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD)) on left ventricular (LV) diastolic function.

Patients and Methods:

We enrolled 63 patients: 21 patients on CAPD, and 42 age- and gender-matched patients on HD; 35 patients were men (55.6%). Median of age was 46.4 (35-57) years. The median duration of renal replacement therapy was 3(2-5) years.


The two groups (HD vs PD) were similar concerning body mass index, dialysis duration and cardiovascular risk factors. The comparison of echocardiographic parameters showed statistically significant differences between two groups, regarding the presence of calcification, cardiac effusion, severely abnormal left ventricular hypertrophy(LVH) and the ratio of mitral velocity to early diastolic velocity of the mitral annulus (E/e’) >13 (p= 0.001, p= 0.003, p= 0.02, p= 0.004, respectively). In multivariate analysis, an E/e’>13 was higher in PD group ( OR= 5.8, CI [1.3-25.5], p=0.002).


The method of dialysis seems to influence LV diastolic function. We observed a higher prevalence of diastolic LV dysfunction in the PD group. Echocardiographic follow up is essential as this could improve the management of cardiovascular complications in dialysis patients.
