Stroke:口服抗凝药的急性缺血性卒中血管内治疗

2020-05-11 MedSci原创 MedSci原创

与不使用OAC相比,接受血管内治疗的缺血性卒中患者使用OAC与有症状的颅内出血风险增加或功能预后更差无关。因此,事先使用OAC不应成为血管内治疗的禁忌证。

口服抗凝剂(OAC)被认为是急性缺血性卒中静脉溶栓治疗的禁忌症。然而,对于既往使用OAC的患者进行血管内治疗的风险和益处知之甚少。近日,心血管疾病领域权威杂志Stroke上发表了一篇研究文章,研究人员旨在比较使用和不使用OAC的患者在接受血管内治疗后的结局。

研究人员分析了2014年3月至2017年11月期间纳入全国范围内前瞻性MR CLEAN登记中心由颅内前循环闭塞引起的急性缺血性卒中患者数据。感兴趣的结局包括有症状的颅内出血和90天时的功能结局(改良的Rankin量表评分)。将组间的结局采用(常规)Logistic回归分析进行比较,并根据预后因素进行调整。

这项研究纳入了362位患者,其中502位(16%)患者使用了OAC。使用和不使用OAC的患者之间症状性颅内出血发生率均无显著差异(5% vs. 6%;校正后的比值比为0.63[95%CI为0.38-1.06])。与不使用OAC的患者相比,接受OAC治疗的患者的功能结局更差(比值比为0.57 [95%CI为0.47-0.66])。然而,观察到的功能结局差异在调整了预后因素后消失了(调整后的比值比为0.91 [95%CI为0.74-1.13])。

由此可见,与不使用OAC相比,接受血管内治疗的缺血性卒中患者使用OAC与有症状的颅内出血风险增加或功能预后更差无关。因此,事先使用OAC不应成为血管内治疗的禁忌证。
