摘　　要：目的探讨尿酸对慢性心力衰竭(心衰)合并心房颤动(房颤)的老年患者心功能及远期预后的相关关系。方法采用回顾性队列研究,连续纳入2018年8月至2020年8月在河北省人民医院心血管内科住院的老年慢性心衰合并房颤患者324例,根据尿酸水平,将患者分为高尿酸组150例和正常尿酸组174例。收集各组临床资料、实验室检查及超声心电图指标,出院后随访3年,研究终点为主要不良心血管事件。结果单因素方差分析显示,纽约心功能分级Ⅳ级的患者尿酸水平显著高于心功能Ⅱ级、Ⅲ级[(445.39±184.54)μmol/L vs(378.86±122.64)μmol/L、(403.50±142.15)μmol/L,P<0.05)]。多因素Cox分析显示,年龄(95%CI:1.012~1.075,P=0.007)、尿酸水平(95%CI:1.000~1.004,P=0.048)、他汀类药物(95%CI:0.215~0.721,P=0.003)与心脏性死亡风险显著相关。结论尿酸与慢性心衰合并房颤的老年患者长期预后有关,对远期发生心脏性死亡有一定预测价值。Objective To investigate the relationship between uric acid(UA)and cardiac function as well as long-term prognosis in elderly patients with chronic heart failure(CHF)and concomi-tant atrial fibrillation(AF).Methods A retrospective cohort study was conducted on 324 consec-utively recruited elderly CHF patients with concomitant AF who were hospitalized in our depart-ment from August 2018 to August 2020.According to their UA level,they were divided into a high UA group(150 cases)and a normal UA group(174 cases).The clinical data,results of labo-ratory tests and echocardiogram indicators were collected.All patients were followed up for 3 years after discharge.The endpoint was major adverse cardiovascular events.Results U nivariate analysis of variance showed that the UA level was significantly higher in the patients with NYHA Class IV than those with Classes II and II(445.39±184.54μmol/L Us 378.86±122.64μmol/L and 403.50±142.15μmol/L,P<0.05).Multivariate Cox analysis indicated that age(95%CI:1.012-1.075,P=0.007),UA level(95%CI:1.000-1.004,P=0.048)and use of statins(95%CI:0.215-0.721,P=0.003)were significantly associated with the risk of cardiac death.Conclu-sion UA is associated with the long term prognosis of elderly CHF patients with concomitant AF,and has certain predictive value for long term cardiac death.
