NEJM:MR指导下醒后卒中的静脉溶栓得到确认

2018-09-01 杨中华 脑血管病及重症文献导读

阿替普酶静脉溶栓时发病4.5h内急性缺血性卒中的标准治疗方案。在14-27%的卒中患者中不知道发病时间,最常见的原因是醒后卒中。这些患者通常被排除在静脉溶栓治疗之外,仅部分患者适合机械性血栓切除术。

阿替普酶静脉溶栓时发病4.5h内急性缺血性卒中的标准治疗方案。在14-27%的卒中患者中不知道发病时间,最常见的原因是醒后卒中。这些患者通常被排除在静脉溶栓治疗之外,仅部分患者适合机械性血栓切除术。

大部分睡眠中发病的卒中,发病时间可能是醒后前几个小时,这些患者可能符合静脉溶栓的时间窗。已知卒中发病时间的MRI研究发现,DWI阳性同时相应区域Flair无明显高信号者,往往提示卒中发生在影像检查前的4.5h内。

2018年7月来自德国的G. Thomalla等在NEJM上公布了WAKE-UP试验结果,他们利用MRI DWI和Flair错配,验乞了不明发病时间卒中采取静脉溶栓的安全性和有效性。

该研究为研究者发起、多中心、随机、双盲、安慰剂对照临床试验。纳入的患者为不明发病时间的卒中患者,皆符合静脉溶栓的其他临床标准,MRI显示DWI急性梗死而Flair相应部位无脑实质高信号(预示着发病4.5h内)。排除了血栓切除术的患者。主要终点为90天良好预后,定义为mRS 0-1。

示例:DWI和Flair错配:


该研究计划纳入800例患者,纳入503例患者后由于资金问题提前结束试验。在该研究中,254例患者随机给予阿替普酶,249例随机给予安慰剂。

阿替普酶和安慰剂组90天预后良好的比例分别为53.3%和41.8%(adjusted OR, 1.61; 95% CI, 1.09 to 2.36; P = 0.02)。两组90天时平均mRS评分分别为1分和2分(adjusted common OR, 1.62; 95% CI, 1.17 to 2.23; P = 0.003)。阿替普酶组和安慰剂组死亡率分别为4.1%和1.2%(odds ratio, 3.38; 95% CI, 0.92 to 12.52; P = 0.07)。症状性颅内出血分别为2%和0.4%(odds ratio, 4.95; 95% CI, 0.57 to 42.87; P = 0.15)。

最终作者认为,对于不明发病时间的急性卒中患者,静脉阿替普酶能够能够改善DWI和Flair错配患者的90天功能预后,但是颅内出血发生率更高。
