Risk factors of heart failure among continuous ambulatory peritoneal dialysis patients

Objective To explore the risk factors of heart failure among continuous ambulatory peritoneal dialysis （CAPD） patients.Methods General information, scale of volume management of CAPD , New York Heart Association （ NYHA） classification and biochemical data were used to analyze independent risk factors of heart failure among CAPD patients .The relationship between level of volume management and incidence of heart failure was also discussed in different nutritional status .Results A total of 114 questionnaires were handed out and 114 were recovered , with the rate of 100%.Level of volume management , serum pre-albumin, blood urea nitrogen were independent risk factors for heart failure among CAPD patients （r=-1.290,-0.006,0.085, respectively;P<0.05）.With a normal level of serum pre-albumin, higher volume management score were associated with lower incidence of heart failure （χ2 =10.542,P<0.05）.No differences were found between volume management scores and incidence of heart failure among those with higher or lower serum pre -albumin levels.Conclusions Improvement of the level of volume management and dialysis adequacy as well as attention to assess nutritional status of CAPD patients can provide references for preventing heart failure .
