Left Ventricular Mass Index in End-Stage Renal Disease Patients during Hemodialysis and Continuous Ambulatory Peritoneal Dialysis.

BACKGROUND: One of the primary reasons for high mortality in end-stage renal disease (ESRD) is cardiovascular disease in patients with renal replacement therapy (RRT). Left ventricular hypertrophy (LVH) significantly predicts mortality and cardiovascular events.

OBJECTIVES: We assess the left ventricular mass index change in two dialysis methods: hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD). The factors associated with increased left ventricular mass index (LVMI).

MATERIALS AND METHODS: We recruit more than 50 HD patients and 45 CAPD patients with LVH of similar age, gender, dialysis duration, and LVMI for one-year follow-up.

RESULTS: The LVMI in the group of HD patients after one year increased from 180.28 ± 45.32 g/m2 to 212.58 ± 66.22 g/m2 ( p  = 0.001), while the LVMI in the group of patients with CAPD increased from 190.16 ± 66.01 g/m2 to 197.42 ± 78 g/m2 ( p  = 0.32). Multivariable logistic regression analysis, we demonstrated that dialysis by HD ( β  = -1,167, 95% CI: 0.104-0.938, p  = 0.036) and anemia treatment lower the goals ( β  = 1.9566, 95% CI: 1.466-34.094, p  = 0.015) were two factors associated with the progression of the LVMI.

CONCLUSION: The LVH of end-stage renal disease patients with HD treatment is worse than CAPD treatment after a follow-up in one year. Dialysis by periodic hemodialysis and anemia treatment that fails to achieve the goal are risk factors associated with increased progression of LVMI in patients with ESRD.
