2017年11月,发表在《Stroke》上的一项观察性研究,调查了接受血管内取栓(ET)治疗的中国急性缺血性卒中(AIS)患者,使用替罗非班治疗的安全性和有效性。

背景和目的:中国患者大部分因大动脉粥样硬化而非心源性栓塞而发生AIS,替罗非班在接受ET治疗的患者中是否安全和有效未知。本研究评估了接受ET治疗的中国AIS患者中,替罗非班的安全性和有效性。

方法:本观察性研究基于一项单中心前瞻性注册研究。2013年1月~2017年2月鉴别出来的使用二代支架进行ET的AIS患者分配到ET单独使用或ET+低剂量替罗非班的组中。首要结局指标为症状性颅内出血(sICH)。次要结局指标包括早期再闭塞率、任何一种ICH发生率、致命性ICH发生率、3个月和长期功能结局。

结果:180例AIS患者被纳入该分析,包括90例替罗非班治疗和90例未进行替罗非班治疗的患者。63例患者(35%)发生了任何一种的ICH,其中的19例(11%)为sICH,9例(5%)为致命性ICH。10例(11%)接受替罗非班治疗的患者发生了sICH,9例(10%)未接受替罗非班治疗的患者发生sICH,没有显着性差异(P=0.808)。替罗非班和非替罗非班治疗的患者分别有4/90例(4.4%)和9/90例(8.9%)发生了早期再闭塞(P=0.370)。161例患者(89%)完成了长期随访,与非替罗非班治疗相比,替罗非班治疗与较低的死亡几率相关(23% vs 44%,P=0.005)。此外,替罗非班与更佳的长期功能独立几率相关(调整OR,4.37;95% CI,1.13~16.97;P=0.033)。

结论:进行ET的AIS患者中,替罗非班与较高的sICH不相关,替罗非班似乎可带来较低的死亡几率和更好的长期功能独立几率。进一步研究需要确定替罗非班在预防早期再闭塞上的有效性、潜在机制及最佳治疗方案。
