Increased left ventricular mass index (LVMI) is commonly observed in patients undergoing peritoneal dialysis (PD). The present study aimed to determine the effect of icodextrin (Ico) on LVMI in PD patients with maintained residual renal function (RRF). This retrospective study included 18 patients (12 men, 6 women; average age: 62 +/- 10 years) diagnosed with indications for PD therapy and divided into two groups: those treated with Ico (Ico group) and without Ico (non-Ico group). Echocardiography was performed at the beginning of continuous ambulatory PD and after 6 and 12 months. A significant reduction in LVMI (p < 0.01) and an increase in ultrafiltration (p < 0.01) were observed after 6 months of lco treatment and were maintained for 12 months. Ejection fraction was significantly lower in the non-Ico group after 12 months (p < 0.01), but was not altered in the Ico group. Blood pressure, cardiothoracic ratio, urine volume, and N-terminal prohormone of brain natriuretic peptide were unaffected by PD treatment up to 12 months. The year-averaged ultrafiltration and the reduction in LVMI were significantly correlated (p < 0.05). Ico effectively improved LVMI and maintained ejection fraction in end-stage renal disease patients within 1 year from PD initiation. Notably, treatment with Ico resulted in a reduction of LVMI (associated with increased ultrafiltration), with no significant reduction in RRF.
