Background: Cardiovascular complications are the main cause of mortality in peritoneal dialysis (PD)[5]. Left ventricular hypertrophy (LVH) is common in dialysis patients and an independent predictor of mortality. Objective: To describe and compare percentages, some related factors to LVH in PD patients and hemodialysis (HD) patients. Materials and methods: A controlled, descriptive cross-sectional study on 148 patients ≥ 18 years old, duration of dialysis ≥ 3 months at Can Tho General Hospital, including 74 PD patients and 74 HD patients (control group).Results: The percentage of LVH in the group of patients on PD was 86.5% (90.6% as concentric hypertrophy, 9.4% as eccentric hypertrophy) similar to the control group (HD) was 90.5% (86.6% as concentric hypertrophy, 13.4% as eccentric hypertrophy). Left ventricular mass index (LVMI) of patient PD had positive correlation with duration of dialysis (r=0.2), systolic blood pressure (r=0.54), diastolic blood pressure (r=0.419) and negative correlated with Hb (r=-0.363), urine 24- hour volume (r=-0.448) in univariate analysis. In multivariable logistic analysis, loss of residual renal function was an independent risk factor for LVH in PD patients. There was no difference in factors related to left ventricular hypertrophy between peritoneal dialysis patients and the control group (HD) (p<0.05). Conclusions: LVH high percentage in PD and HD patients, similar; there is no difference in factors related to LVH in two group. In PD patients, loss of residual renal function is an independent risk factor for LVH.
