The association between BP and mortality in patients on chronic peritoneal dialysis

Abstract
Background. The relationship between blood pressure (BP) and mortality in haemodialysis patients is unconventional. It is not clear if this is the consequence of uraemia or related to the dialysis type. The goal of this project was to identify the relationship between BP and mortality in patients on chronic peritoneal dialysis (PD). Methods. Patients on PD (n = 1053) from the USRDS prospective DMMS Wave 2 study were analysed. Primary outcomes were all-cause and cardiovascular mortality and duration of hospitalization. Results. Low systolic BP categories, PPPPConclusion. Systolic BP 120 mmHg is associated with fewer hospital days. Aggressive treatment of hypertension in the PD population should be cautioned.
