Pulse pressure (PP) is an indirect measure of arterial compliance and an elevated value is considered a cardiovascular risk factor in models for prediction of hypertension, end-stage renal disease, and various cardiovascular diseases (1–5). Pulse pressure is often considered a better tool for prediction of cardiovascular diseases than other blood pressure parameters (2,3,6). Higher small solute transport status is associated with hypoalbuminemia and greater comorbidity, thus it is a factor of increased risk of atherosclerosis compared with low-transporter status in peritoneal dialysis (PD) patients (7). A previous study reported that higher peritoneal transport status exacerbates atherosclerosis in PD patients (8). It has also been shown that elevated peritoneal transport rate may develop as a result of endothelial or vessel dysfunction (9). Arterial stiffness is also associated with increased arterial permeability (10). In this study, we investigated the hypothesis that PP, a marker of arterial stiffness, is associated with higher peritoneal transport status in PD patients.
