持续非卧床腹膜透析患者心衰发生的危险因素分析

目的：探讨持续非卧床腹膜透析（ CAPD ）患者心衰发生的危险因素。方法采用CAPD患者容量管理量表、纽约心脏协会（ NYHA）的心功能分级及生化指标等调查分析影响CAPD患者心衰发生的独立危险因素。探讨不同营养状态下，容量管理水平与心衰发生的关系。结果共发放调查问卷114份，收回114份，有效回收率为100％。容量管理水平、血清前白蛋白、尿素氮是引起CAPD患者发生心衰的独立危险因素（ r值分别为-1．290，-0．006，0．085；P＜0．05）。前白蛋白正常组患者中，容量管理水平与心衰发生率呈负相关（χ2＝10．542，P＜0．05）。结论提高CAPD患者容量管理水平及透析充分性，重视营养状态的评估，可为预防心衰的发生提供依据。

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＆lt;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＆lt;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 .
