维持性血液透析患者发生心力衰竭的影响因素

目的了解维持性血液透析患者发生心力衰竭的危险因素，为预防和治疗心力衰竭提供依据。方法采用回顾性病例对照研究方法，收集病例组和对照组的可能影响因素，利用logistic回归分析方法筛选发生心力衰竭的危险因素。结果维持性血液透析患者的心力衰竭发生率为34．4％。多因素logistic回归结果显示，年龄（OR=1．184）、透析时间（OR=1．536）、高血压（OR：2．940）、心脏病（OR=6．030）为危险因素，而血红蛋白（OR=0．752）、血清白蛋白（OR=0．708）、血钙（OR=0．004）则为保护因素。结论影响血液透析患者发生心力衰竭的危险因素包括年龄越大、透析时间越长、高血压、心脏病、低血红蛋白、低血清白蛋白、血钙浓度低等。

Analysis on influencing factors of heart failure in patients undergoing maintenance hemodialysis

[ Objective ] To understand the risk factors of heart failure in patients undergoing maintenance hemodialysis, provide the basis for prevention and treatment of heart failure. [ Methods] By using the method of retrospective case-control study, the possible influencing factors were collected from the case group and the control group, and the risk factors of heart failure were analyzed by logistic regression. [ Results] The incidence rate of heart failure in patients undergoing maintenance hemodialysis was 34.4%. The results of multiple factors logistic regression showed that the risk factors were age （OR--1. 184}, time of dialysis （OR = 1. 536） , hypertension （ OR = 2. 940 ） and heart disease （ OR = 6. 030 ） , while the protective factors included hemoglobin （ OR = 0. 752 ） , se- rum albumin （ OR = 0. 708 ） and blood calcium （ OR = 0. 004）. [ Conclusion] The risk factors of heart failure in patients undergoing maintenance hemodialysis are older age, longer time of dialysis, hypertension, heart disease, low hemoglobin, lower level of serum albumin and lower concentration of blood calcium.
