2月19日~21日,2020年国际卒中大会(ISC2020)于美国洛杉矶隆重开幕,其中多项研究在大会上公布。对于具有良好的灌注成像的缺血性卒中患者,静脉阿替普酶可减少发病4.5-9h及醒后卒中(发病时间不明)的患者残疾预后。本研究探讨通过分析EXTEND和EPITHET两项临床试验在的结果,分析再灌注对减少残疾预后的益处,该研究也在线发表在stroke杂志上。患者在灌注不匹配成像后随机接受阿替普酶

2月19日~21日,2020年国际卒中大会(ISC2020)于美国洛杉矶隆重开幕,其中多项研究在大会上公布。对于具有良好的灌注成像的缺血性卒中患者,静脉阿替普酶可减少发病4.5-9h及醒后卒中(发病时间不明)的患者残疾预后。本研究探讨通过分析EXTEND和EPITHET两项临床试验在的结果,分析再灌注对减少残疾预后的益处,该研究也在线发表在stroke杂志上。

患者在灌注不匹配成像后随机接受阿替普酶或安慰剂治疗,再灌注定义为24h时Tmax> 6s病变体积减少> 90%。采用调整基线年龄和NIHSS评分的常规Logistic回归分析整体功能改善结局(90天mRS评分),包括再灌注*时间到随机化相互作用项,以及4.5-6h、6-9h和醒后卒中时间层。症状性出血定义为伴≥4分NIHSS增高的大实质血肿(SITS)。

主要研究结果显示, 270/294(92%)患者可评估再灌注,其中阿替普酶组为68/133(51%),安慰剂组为38/137(28%)(p <0.001)。再灌注组中位年龄为76岁(IQR 66-81),未再灌注为74(IQR 64.5-81);再灌注NIHSS中位数评分为10(IQR 7-15),未再灌注为12(IQR 8-17.5)。 

有序迁移分析(ordinal “shift” analysis)结果:总体而言,再灌注常见优势比7.7(95%CI 4.6-12.8,p <0.0001)。随机分组再灌注效应的有益作用无异质性(p=0.63)。在4.5-6h,6-9h和醒后卒中各时间层中,再灌注与功能结局改善显著相关(图1)。在所有294位患者中评估症状性出血,其中阿替普酶组(van Elteren p=0.66)中,4.5-6h为 3/51(5.9%),6-9h为2/28(7.1%),醒后卒中为4/73(5.5%)。

该研究结果提示,在所有时间段均具有强大的再灌注优势,而无症状性出血的不同风险,结果支持静脉注射阿替普酶在灌注错配-选择患者的4.5-9h和醒后卒中时间窗口内的持久治疗效果。
