摘要:
目的 探讨维持性血液透析患者发生心血管疾病的相关危险因素。 方法 回顾性收集2019年1月-2020年10月蚌埠医学院第三附属医院血液透析室行维持性血液透析治疗的慢性肾功能不全尿毒症期患者126例作为研究对象, 根据患者是否发生心血管疾病将其分为心血管并发症组(74例)和无心血管并发症组(52例)。比较2组患者一般资料和实验室相关检查指标的差异, 并采用二分类logistic回归法对维持性血液透析患者发生心血管疾病的相关危险因素进行分析。 结果 与无心血管并发症组比较, 心血管并发症组年龄、透析龄、血尿酸、同型半胱氨酸、超敏C反应蛋白、白介素-6水平较高, 而前白蛋白、高密度脂蛋白胆固醇、血镁水平较低, 差异有统计学意义(均P < 0.05);二分类logistic回归分析显示, 年龄大、透析龄长、高同型半胱氨酸血症、高尿酸血症、高水平的超敏C反应蛋白以及白介素-6是维持性血液透析患者发生心血管疾病的独立危险因素(OR=1.441, P=0.029;OR=2.212, P=0.019;OR=1.384, P=0.030;OR=5.056, P < 0.001;OR=3.163, P=0.013;OR=3.802, P=0.009)。 结论 年龄大、透析龄长、高同型半胱氨酸血症、高尿酸血症、高水平的超敏C反应蛋白以及白介素-6可能是维持性血液透析患者发生心血管疾病的独立危险因素。 Abstract:Objective To study the risk factors of cardiovascular disease in maintenance haemodialysis patients. Methods A total of 126 patients in the uremic phase of chronic renal insufficiency who underwent maintenance haemodialysis in the haemodialysis unit of the Third Affiliated Hospital of Bengbu Medical College from January 2019 to October 2020 were retrospectively enrolled.They were divided into the cardiovascular complication group (n=74) and group without cardiovascular complications (n=52) according to whether the patients developed cardiovascular disease.The differences of general information and laboratory examination indexes between the two groups were compared, and the risk factors of cardiovascular disease in maintenance haemodialysis patients were analysed by binary logistic regression. Results Age, long dialysis age, serum uric acid, homocysteine, high sensitivity C-reactive protein and interleukin-6 levels were higher, whereas prealbumin, high-density lipoprotein cholesterol and serum magnesium levels were lower in the group with cardiovascular complications than in the group without cardiovascular complications (all P < 0.05).Binary logistic regression analysis showed that age, dialysis age, hyperhomocysteinemia, hyperuricemia, high levels of high-sensitivity C-reactive protein and interleukin-6 were independent risk factors for the development of cardiovascular disease in maintenance haemodialysis patients (OR=1.441, P=0.029;OR=2.212, P=0.019;OR=1.384, P=0.030;OR=5.056, P < 0.001;OR=3.163, P=0.013;OR=3.802, P=0.009). Conclusion Old age, long dialysis age, hyperhomocysteinemia, hyperuricemia, high levels of high-sensitivity C-reactive protein and interleukin-6 may be independent risk factors for cardiovascular disease in maintenance haemodialysis patients. -
