Stroke:脆弱指数Meta分析证实<3小时静脉注射阿替普酶的益处高度可靠!

2022-07-02 MedSci原创 MedSci原创

3小时内静脉注射阿替普酶治疗急性缺血性卒中是医学上最安全稳健的治疗方法之一。

体弱是一种老年性综合症,表现为容易诱发健康事件和功能储备下降。脆弱指数是用赤字的总和除以0到100之间的连续标度的可能赤字的总数,累积脆弱指数(FI)分析能够量化静脉阿替普酶的核心适应症--治疗发病后3小时内致残的急性缺血性卒中的证据强度。

为此,来自UCLA的学者对使用阿替普酶患者非残疾(改良的Rankin量表[mRS]评分0-1)、功能独立(mRS评分0-2,次要疗效)和死亡结果进行了Meta分析(研究水平)或确定(个体参与者水平)。在每个连续的随机对照试验(RCT)之后,连续进行单个试验和累积FI分析。FI评分分类如下:不健康(FI 0-4),有点健康(FI 5-12),健康(FI 13-33),以及十分健康(FI >33)。

结果显示,1995年至2021年,共发现了9项关于急性缺血性卒中3小时内静脉注射阿替普酶的随机对照试验。在研究层面的荟萃分析中,阿替普酶增加了39%非残疾的结果(mRS评分0-1),31.0%对22.3%,相对风险,1.39(95% CI,1.20-1.61);P<0.00001;增加了29%功能独立(mRS评分0-2),39.7%对31.2%,相对风险,1.29(95% CI,1.14-1.45),P<0.000;并且没有改变死亡率,24.1%对26.1%;P=0.23。

研究层面的荟萃分析的总体FI都非常稳健,对于mRS评分0-1和mRS评分0-2,分别为42和40。此外,随着1995年2项NINDS-TPA试验的发表,静脉注射阿替普酶的优势具有强大的证据力量,在2012年增加到高度稳健,并在2021年保持。

综上,3小时内静脉注射阿替普酶治疗急性缺血性卒中是医学上最安全稳健的治疗方法之一。
