Abstract: Objective To explore the value of normalized extracellular fluid volume by body height (ECW/h) in the estimation of volume overload and ventricular remodeling in patients with continuous ambulatory peritoneal dialysis (CAPD). Methods Data about body composition and echocardiography were collected and used to analyze the correlation of ECWh with volume overload and ventricular remodeling. We also analyzed the differences of volume overload and ventricular remodeling in patients with ECW/h ＞9.04 L/m and those with ECW/h＜9.04L/m. Results Pearson’s analysis showed that ECWh was positively correla-ted with the volume load parameters of LVEDD and LAD (r=0.507 and 0.492, respectively; P＜0.001) and the ventricular remodeling parameters of LVPWT, LVM, IVST and LVMI (r =0.463, 0.581, 0.403 and 0.404, respectively; P＜0.001. Volume overload and ventricular remodeling indicators including LVEDD, LAD, LVPWT, LVM, IVST, and LVMI were higher in patients with ECW/h＞9.04 L/m than in those with ECW/h＜ 9.04L/m. Conclusion ECW/h is valuable in the clinical evaluation of volume overload and ventricular remodeling in CAPD patients.
