Factors associated with blood pressure variability in patients on maintenance peritoneal dialysis

Abstract

Objective To explore the related factors of weekly blood pressure variability (BPV) on maintenance peritoneal dialysis (MPD).Methods A total of 142 patients on MPD for at least 3 months were recruited. Blood pressure was assessed weekly by variation coefficient (CV) of systolic blood pressure in morning. The relevant clinical data was collected. The association of BPV and predictors were estimated by a mixed-effect linear model. Results Longer dialysis vintage was associated with elevated weekly BPV (P0.05). Conclusions Weekly BPV may be affected by dialysis vintage, hemoglobin concentration, daily fluid removal and dosing of calcium antagonists.
