JAMA Neurology:脑出血后卒中的抗血小板治疗,效果如何

2021-09-19 Freeman MedSci原创

本研究发现抗血小板治疗对复发性ICH或所有主要血管事件没有统计学上的显著影响

在高收入国家,至少有三分之一的成年人因自发性(非创伤性)脑内出血(ICH)引起的卒中,由于他们的合并症和其他血管疾病的危险因素,已经在口服抗血栓(抗血小板或抗凝血剂)药物治疗。即使考虑到这些危险因素,自发性ICH的幸存者发生心肌梗死和缺血性中风的风险也高于普通人群,他们发生所有出血性或缺血性主要血管事件的风险仍然较高,每年约8%。

抗血小板药物可能有利于自发性ICH的幸存者,但它们对主要血管事件的影响还不确定。2021年6月11日的一项系统综述提出,重新启动或停止抗血栓药物随机试验(RESTART)是唯一发表的比较ICH后开始与避免抗血小板治疗效果的随机临床试验。

RESTART纳入了采取抗血栓治疗的ICH幸存者,以估计开始与避免抗血小板治疗,对复发症状性ICH的影响,以及这种风险是否可能超过闭塞性血管事件的任何减少。

在对537名参与者进行了中位数2年的随访后,RESTART的主要结果排除了所有的风险,但抗血小板治疗后复发ICH的风险有非常小的增加(调整后的危险比[HR],0.51;95%CI,0.25-1.03;P = .06)。


因此,该试验的资助者允许将剩余的资金用于随访所有愿意继续参加试验的幸存者。
这使得爱丁堡大学的Rustam Al-Shahi Salman等人,对有幸存者的随访时间再延长2年,以提高大多数参与者3年内的效果估计的精确度,并为一些参与者提供长达7年的相关治疗效能信息。

从2013年5月22日到2018年5月31日,这项前瞻性、开放性、盲端点、平行组的随机临床试验研究了英国122家医院的537名参与者。参与者为18岁或以上的个体,他们在发生ICH、停止抗血栓治疗并存活24小时时,曾采取抗血栓治疗预防闭塞性血管疾病。初次随访于2018年11月30日结束后,年度随访延长至2020年11月30日,试验队列的中位数为3.0年(四分位数范围[IQR],2.0-5.0年)。

对参与者进行了长达7年的主要结果(复发性症状性ICH)和次要结果(所有主要血管事件)的跟踪。使用Cox回归法分析所有随机参与者的数据,并对最小化协变量进行调整。

共有537名患者(中位年龄,76.0岁;360名[67.0%]男性;ICH发病后的中位时间,76.0天;IQR,29.0-146.0天)被随机分配到开始(n = 268)或避免(n = 269 )抗血小板治疗。

复发性ICH这一主要结果影响了被分配到抗血小板治疗的268名参与者中的22人(8.2%),而被分配到避免抗血小板治疗的268名参与者中的25人(9.3%)(调整后的危险比,0.87;95%CI,0.49-1.55;P=0.64)。

主要血管事件影响了72名分配到抗血小板治疗的参与者(26.8%),而87名分配到避免抗血小板治疗的参与者(32.5%)(危险比,0.79;95%CI,0.58-1.08;P = .14)。

在以前采取过抗血栓治疗的ICH患者中,本研究发现抗血小板治疗对复发性ICH或所有主要血管事件没有统计学上的显著影响。这些发现为医生在ICH后使用抗血小板治疗提供了一些保证,如果是为了二级预防主要血管事件。
