Stroke:后循环和前循环卒中静脉溶栓治疗的安全性和结局

2020-01-11 xing.T MedSci原创

由此可见,PCS静脉溶栓治疗后发生出血并发症的风险是ACS的一半,具有相似的功能结局和更高的死亡风险,并承认美国国立卫生研究院卒中量表对卒中严重度或梗死面积调整的限制。

在接受静脉溶栓治疗的急性卒中患者中后循环卒中(PCS)占5%至19%。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PCS和前循环卒中(ACS)患者在静脉溶栓后的安全性和结局,并将结果在荟萃分析中进行合并。

研究人员纳入了2013年至2017年期间卒中溶栓登记中心安全实施治疗试验的患者计算机断层扫描/磁共振血管造影闭塞数据。结局为实质性血肿、根据SITS-MOST(在卒中监测研究中安全实施溶栓治疗)、ECASS II(第二次欧洲合作卒中研究)和NINDS(神经系统疾病和卒中定义)有症状的脑出血(SICH)、三个月改良的Rankin量表评分和死亡。研究人员使用逆概率治疗权重调整了SICH危险因素(年龄、性别、美国国立卫生研究院卒中量表、血压、葡萄糖和心房颤动)和中心,然后计算平均治疗效果(ATE)。并对13项研究进行荟萃分析,比较静脉溶栓后PCS和ACS患者的结局。

在5146例患者中,有753例患有PCS(14.6%)。PCS患者的美国国立卫生研究院卒中量表中位数较低:7(四分位间距,4-13) vs. 13(7-18),P<0.001,脑血管危险因素更少。PCS与ACS患者的实质血肿发生率分别为3.2%和7.9%,ATE(95%CI):-4.7%(-6.3%至3.0%); SICH SITS-MOST分别为0.6%和1.9%,ATE:-1.4%(-2.2%至-0.7%); SICH NIND分别为3.1%和7.8%,ATE:-3.0%(-6.3%至0.3%); SICH ECASS II为1.8%和5.4%,ATE:-2.3%(-5.3%至0.7%)。在PCS与ACS患者中,3个月的结局(数据可用性为70%)为死亡分别为18.5%和20.5%,ATE:6.0%(0.7%至11.4%);改良Rankin量表评分0-1,分别为45.2%和37.5%,ATE:1.7%(-6.6%至3.2%);改良Rankin量表评分0–2,分别为61.3%和49.4%,ATE:2.4%(3.1%至7.9%)。荟萃分析显示PCS与ACS发生SICH的相对风险为0.49(95%CI为0.32-0.75)。

由此可见,PCS静脉溶栓治疗后发生出血并发症的风险是ACS的一半,具有相似的功能结局和更高的死亡风险,并承认美国国立卫生研究院卒中量表对卒中严重度或梗死面积调整的限制。
