Circ CQO:质子泵抑制剂与DAPT,究竟能否共生?

2015-01-29 伊文 心在线

一项荟萃分析发现,评估质子泵抑制剂(PPIs)与双联抗血小板治疗(DAPT)联合应用时,心血管结局是否恶化的35研究,结果差异显著,甚至互相矛盾。 研究概述 该研究分析了1995年~2012年间的35项观察性及随机对照研究(RCTs)。其中5项研究(4项RCTs及1项观察性研究)的内容是:奥美拉唑或埃索美拉唑联合DAPT,与单独应用DAPT的效果比较;另外30项观察性研究的内容是:

一项荟萃分析发现,评估质子泵抑制剂(PPIs)与双联抗血小板治疗(DAPT)联合应用时,心血管结局是否恶化的35研究,结果差异显著,甚至互相矛盾。

研究概述

该研究分析了1995年~2012年间的35项观察性及随机对照研究(RCTs)。其中5项研究(4项RCTs及1项观察性研究)的内容是:奥美拉唑或埃索美拉唑联合DAPT,与单独应用DAPT的效果比较;另外30项观察性研究的内容是:PPIs此类药物联合DAPT,与单独应用DAPT比较。

结果各异

针对PPIs一类药物的研究一致指出,PPIs联合DAPT较仅应用DAPT,1年的事件发生率较高。然而评估奥美拉唑 vs. 安慰剂的研究,则未发现二者在缺血性结局方面有差异。

4项RCTs中,有3项都发现,奥美拉唑联合DAPT较仅应用DAPT,6个月时的胃肠道(GI)出血率较低。但是,4项观察性研究却得出完全相反的结果。研究者指出,整体上,有中等证据支持应用PPIs可减少GI出血。

研究者还强调,研究中不可避免地存在不可测量的混杂因素,将PPIs作为一类药物进行分析,不是基于有力证据的。有同期述评称,支持混杂因素是导致观察性研究及RCTs结果不一致这一解释。

美国心脏学会(AHA)/美国心脏病学会(ACC)的指南建议,对于服用氯吡格雷的患者,医生需评估是否应开始或继续应用PPIs。指南中还描述了PPIs联合DAPT的益处及潜在危险。该荟萃分析同样支持,联合应用二者时,应谨慎。

GI出血

该研究的真正价值在于,让我们更加关注减少GI出血的需要,尤其是对于服用强效抗血栓药物的患者而言。而遗憾的是,研究中发现的GI出血减少,早被淹没在了争论二者相互作用的喧嚣中。

实际上,我们更该担忧的问题是,目前PPIs联合氯吡格雷、DAPT、三联抗血小板治疗的应用率还非常低。对于氯吡格雷及PPIs相互作用的担心,是不必要的,如何优化PPIs的GI获益,才是需要解决的问题。

警示标注

人们关于特定PPIs对于氯吡格雷代谢不良影响的担忧,促使FDA分别在2009年及2011年,对奥美拉唑及埃索美拉唑进行了警示信息标注。但是,近些年,医生的顾虑似乎在逐渐减少。
