GDF-15对GRACE风险校正能提高对非ST段压低急性冠脉综合征的预测价值

 GDF-15是一种新的评价指标, 近年来人们一直在探寻新的敏感的和特异性评价指标。传统评价冠脉事件的指标如LDH,CK-MB,Troponin I等等,近年来又发现pro-BNP,MMP-2,6,9,TIMP-2,PⅢNP,CD40L等等,如果将这些指标间相互作用,以及用于心血管事件的预测,具有相当重要的意义,如果在临床研究中注意收集这些信息,有助于形成新的临床发现。

 德国学者的一项研究表明,入院时生长分化因子15(GDF-15)单次测定可显著增强急性冠脉事件注册(GRACE)评分的预测价值。论文于2011年12月23日在线发表于《欧洲心脏杂志》(Eur Heart J)。

  GRACE是一项经验证的非ST段抬高型急性冠脉综合征(NSTE-ACS)评分系统。此项研究共纳入1122例NSTE-ACS患者,并在其入院时确定了GRACE评分、GDF-15和N末端前B型利钠肽(NT- proBNP)。主要终点为6个月全因死亡率或非致死性心肌梗死(MI)。在推导人群(754例;66例出现主要终点)中制定统计算法,并将其应用于验证人群(368例;33例)。

  结果显示,在验证人群中,利用GDF-15对GRACE风险估计进行校正可使受试者工作特征曲线(AUC)下面积由0.79升高至 0.85(P<0.001)。鉴别力改善由鉴别力综合改善(IDI)0.055被加以证实。净31%的无事件患者被重新分类为低危,净27%的伴事件患者被重新分类为高危,从而使净分类改善达到0.58(P=0.002)。将NT-proBNP添加至GRACE评分中可产生相似的鉴别力和重新分类改善。将GDF-15添加至包含NT-proBNP和GRACE的模型中可进一步改善模型效能。
