心源性休克合并急性冠脉综合征的死亡率很高,合理使用机械循环支持等先进疗法需要进行客观的风险分层。一些临床变量已被用于判断心源性休克的风险。

近期,一项发表在杂志Crit Care Med上的研究旨在评估可溶性ST2和氨基末端前B型利钠肽的连续监测对心源性休克风险分层临床参数的附加意义。

CardShock(www.clinicaltrials.gov NCT01374867)是一项心源性休克的前瞻性欧洲跨国研究。主要研究了CardShock风险评分,其是由基线时的7个临床变量计算,并与短期死亡率相关。
此项研究的受试对象为急性冠状动脉综合征引起的心源性休克患者(n = 145)。在此项子研究中,在ICU或心脏护理医院停留期间的八个时间点分析来自受试患者的血浆样品,评估生物标志物的额外预后价值。

此项研究显示:可溶性ST2和氨基末端前B型利尿钠肽的组合很好的区别了30天死亡率(曲线下面积为在心源性休克起始后12小时为0.77,5-10天为0.93)。12小时时,与一个或两个生物标志物均不升高相比(分别为31%或10%),两组生物标志物均升高(可溶性ST2≥500ng/ mL,氨基末端前B型利尿钠肽≥4,500ng/ L)的患者30天死亡率高(79%; p <0.001)。在12小时的时候,将可溶性ST2和氨基末端前B型利尿钠肽联合测定,加入CardShock风险评分可以重新正确分类11%的患者。

此项研究结果表明:可溶性ST2和氨基末端前B型利尿钠肽的组合提供了急性冠状动脉综合征相关心源性休克患者的临床变量之外的早期风险评估,可能有助于这些患者的治疗决策。
