摘　　要：目的探讨颈总动脉内膜中层厚度(CCA-IMT)和颈动脉-股动脉脉搏波传导速度(cfPWV)对维持性血液透析(MHD)患者远期预后的影响。方法选取2014年1—3月于北京积水潭医院和首都医科大学附属北京朝阳医院治疗的91例MHD患者的临床及随访资料进行回顾性分析。收集患者的基线资料,随访前检测CCA-IMT和cfPWV。随访85个月,记录MHD患者的生存情况,分为存活组(36例)和死亡组(55例);根据CCA-IMT将患者分为CCA-IMT增厚组(43例,≥0.9 mm)和CCA-IMT正常组(48例,<0.9 mm);根据cfPWV将患者分为cfPWV升高组(37例,≥12 m/s)和cfPWV正常组(54例,<12 m/s)。分析MHD患者全因死亡和心脑血管事件死亡的危险因素。结果死亡组年龄、糖尿病肾病比例、高敏C反应蛋白水平、血清铁蛋白水平、CCA-IMT均高于/大于生存组(均P<0.05)。Kaplan-Meier生存曲线分析结果显示,CCA-IMT增厚组全因死亡率和心脑血管事件死亡率均高于CCA-IMT正常组(均Log-rank P<0.001);cfPWV升高组全因死亡率和心脑血管事件死亡率均高于cfPWV正常组(Log-rank P=0.017、0.025)。多因素Cox回归分析结果显示,年龄(风险比=1.035,95%置信区间:1.005~1.066,P=0.023)、糖尿病肾病(风险比=3.497,95%置信区间:1.886~6.485,P<0.001)、CCA-IMT≥0.9 mm(风险比=2.077,95%置信区间:1.114~3.872,P=0.021)、SF(风险比=1.001,95%置信区间:1.000~1.002,P=0.019)是MHD患者全因死亡的独立危险因素;糖尿病肾病(风险比=2.632,95%置信区间:1.202~5.765,P=0.016)、CCA-IMT≥0.9 mm(风险比=6.261,95%置信区间:2.611~15.010,P<0.001)、cfPWV≥12 m/s(风险比=2.644,95%置信区间:1.253~5.577,P=0.011)是MHD患者心脑血管事件死亡的独立危险因素。结论CCA-IMT和cfPWV增加是MHD患者远期全因死亡和心脑血管事件死亡的独立危险因素。Objective To explore the impact of common carotid artery intima-media thickness(CCA-IMT)and carotid-femoral pulse wave velocity(cfPWV)on the long-term outcome in maintenance hemodialysis(MHD)patients.Methods Clinical and follow-up data of 91 patients who underwent MHD in Beijing Jishuitan Hospital and Beijing Chao-yang Hospital,Capital Medical University from January to March 2014 were retrospectively analyzed.The baseline data of patients was collected,CCA-IMT and cfPWV before follow-up were measured.MHD patients were followed-up for 85 months,survival of patients was recorded,and patients were divided into survival group(36 cases)and death group(55 cases);according to CCA-IMT,patients were divided into CCA-IMT thickening group(43 cases,≥0.9 mm)and CCA-IMT normal group(48 cases,<0.9 mm);according to cfPWV,patients were divided into cfPWV elevating group(37 cases,≥12 m/s)and cfPWV normal group(54 cases,<12 m/s).The risk factors of all-cause death and cardiocerebral death in MHD patients were analyzed.Results The age,diabetic nephropathy(DN)rate,high-sensitivity C-reactive protein level,serum ferritin level and CCA-IMT in the death group were higher than those in the survival group(all P<0.05).Kaplan-Meier survival curve analysis showed that the rates of all-cause death and cardiocerebral death in the CCA-IMT thickening group were higher than those in the CCA-IMT normal group(both Log-rank P<0.001);the rates of all-cause death and cardiocerebral death in the cfPWV elevating group were higher than those in the cfPWV normal group(Log-rank P=0.017,0.025).Multivariate Cox regression analysis showed that age[hazard ratio(HR)=1.035,95%confidence interval(CI):1.005-1.066,P=0.023],DN(HR=3.497,95%CI:1.886-6.485,P<0.001),CCA-IMT≥0.9 mm(HR=2.077,95%CI:1.114-3.872,P=0.021)and serum ferritin(HR=1.001,95%CI:1.000-1.002,P=0.019)were independent risk factors for all-cause death in MHD patients;DN(HR=2.632,95%CI:1.202-5.765,P=0.016),CCA-IMT≥0.9 mm(HR=6.261,95%CI:2.611-15.010,P<0.001)and cfPWV≥12 m/s(HR=2.644,95%CI:1.253-
