Lancet:STEMI进行PCI治疗时,进行血栓抽吸风险大!

2015-10-14 崔倩 译 MedSci原创

两个大型试验已经报告了1年ST段抬高心肌梗死(STEMI)血栓抽吸后矛盾的结果。在血栓抽吸的最大随机试验1年的随访过程中,该研究的目的是明确的长期利益,以帮助指导临床实践。该STEMI患者(TOTAL)患者使用常规吸入性血栓切除术PCI治疗 vs PCI单独治疗的试验是一项前瞻性,随机,研究者发起的试验,对10732例STEMI患者进行常规人工血栓抽吸 vs 经皮冠状动脉介入治疗(PCI)进行了比

两个大型试验已经报告了1年ST段抬高心肌梗死(STEMI)血栓抽吸后矛盾的结果。在血栓抽吸的最大随机试验1年的随访过程中,该研究的目的是明确的长期利益,以帮助指导临床实践。

该试验是一项前瞻性、随机试验,研究人员对10732例STEMI患者进行经皮冠状动脉介入常规人工血栓抽吸 vs 经皮冠状动脉介入治疗(PCI)进行了比较。符合条件的成年患者(年龄≥18岁)来自于20个国家的87家医院,在发病12小时内被随机(1:1)分配接受常规人工血栓PCI治疗或PCI单独治疗。置换块随机化(具有可变块大小),通过一个24小时计算机化中央系统完成,并由中心进行分层。参与者和研究者都知道治疗分配。该试验在180天的主要终点:心血管死亡、心肌梗死、心源性休克、或心脏衰竭方面没有显示出差异。然而,结果显示改善ST段下降和远端栓塞的替代结果有所改善,但这一结果是否会转化为更长期的效益仍不清楚。在这个长期随访的整个研究中,该实验报告了在1年时结果的主要终点(心血管死亡、心肌梗死、心源性休克、或心脏衰竭)和次要结果。主要结果的分析是通过改良的意向治疗完成的,只包括那些接受指数PCI的患者。

在2010年08月和2014年7月25日之间,10732例符合条件的患者参与此研究,并被随机分配到接受血栓切除术其次进行PCI治疗(n=5372),或单独PCI治疗(n=5360)。在那些每组没有接受PCI的患者被排除此研究(PCI治疗组337例,血栓组和PCI治疗组331例),最终研究人群包括10064例(血栓组和PCI治疗组5035例,PCI组5029例)。1年主要终点发生率血栓组395例(8%),PCI治疗组394例(8%)(危险比[HR]1.00[95%Cl为0.87-1.15],p=0.99)。1年内心血管死亡血栓组发生179例(4%),PCI单独组为192例(4%)(HR 0.93[95%Cl 0.76-1.14,P=0.48)。关键安全性结果,1年之内卒中,血栓组发生60例(1.2%),PCI单独组发生36例(0.7%)(HR 1.66[95%Cl 1.10-2.51],p=0.015)。

对于STEMI,PCI过程中进行血栓抽吸,没有减少长期的临床结果,并可能增加卒中的风险。因此,血栓抽吸不可以再被推荐作为STEMI治疗的一个常规策略。
