[摘要] 目的 评估尿酸对扩张型心肌病(DCM)心衰患者预后的价值。方法 检测78例DCM患者入院时血尿酸(SUA),并进行中位数为13.5(3~25)个月的随访,观察心血管事件(心源性死亡及心衰失代偿再入院)情况。结果 失访4例,事件组38例,非事件组36例。(1)与非事件组相比,事件组SUA更高[(576.7±182.9)μmol/L vs (462.4±164.2)μmol/L](P<0.01)。(2)SUA对预后判断的ROC曲线下面积为0.673,最佳截定点565 μmol/L,灵敏度0.579,特异度0.778。(3)Kaplan-meier生存曲线分析表明SUA>565 μmol/L组的再发心血管事件风险是SUA≤565 μmol/L组的4.813倍(95%CI:1.742~13.292,P=0.002)。结论 SUA水平对DCM患者预后评估有重要价值。SUA>565 μmol/L提示预后不良。 |

[Abstract] Objective To evaluate the prognostic value of serum uric acid(SUA) in patients with dilated cardiomyopathy(DCM) complicated by heart failure(HF).Methods Seventy-eight patients hopitalitalized with DCM were included in this study. SUA were measured on admission. All patients discharged were followed up for a median of 13.5 months (3~25 months).The cardiovascular event were observed including cardiac death or readmission due to decompensated HF.Results Among 78 patients, 4 patients failed to be followed up,there were 38 patients in the events group,36 patients in non-event group.(1)Compared with non-event group, the event group had a significiant higher SUA level [(576.7±182.9)μmol/L vs (462.4±164.2)μmol/L], P<0.01.(2)Area under the curve for SUA in evaluating prognosis of DCM patients was 0.673,optimal cut point was 565 μmol/L,sensitivity 0.579,specificity 0.778.(3)The analysis of Kaplan-Meier survival curve showeded,SUA>565 μmol/L on adminssion were associated with increased cardiovascular events.The risk of recurrent cardiovascular events of group with SUA>565 μmol/L was 4.813 times as much as that of group with SUA≤565 μmol/L(Hazard Ratio[HR]=4.813, 95%CI:1.742~13.292,P=0.002).Conclusion SUA level has important prognosis value in patients with DCM. SUA>565 μmol/L predicted an unfavourable prognosis. |
