stroke:溶栓治疗对急性缺血性脑卒中合并病前残疾患者的疗效

2022-06-19 MedSci原创 MedSci原创

与未接受IVT的患者相比,残疾患者使用IVT与更好的结果有关,但没有统计学意义上的sICH或死亡风险增加。

在急性缺血性卒中中使用阿替普酶的随机对照试验排除了卒中前残疾的患者,因此阿替普酶在这一人群中的获益仍不确定。为此,来自加拿大的学者进行了一项系统回顾和荟萃分析,以研究溶栓治疗对病前残疾患者的效果。结果发表在stroke杂志上。

研究人员根据流行病学观察研究的Meta分析指南进行了系统回顾,并检索了报告急性缺血性卒中预后残疾(改良Rankin量表评分mRS,3-5分)患者静脉溶栓(IVT)的研究,与未治疗患者或无预后残疾的治疗患者进行比较。主要结果是在90天内恢复到病前残疾。次要结果包括90天后有利的功能结果的比率和几率(mRS0-2或恢复到病前mRS),症状性脑内出血(sICH),以及90天的死亡率。

结果共纳入了8篇文章,涉及103988名患者。与未接受IVT治疗的患者相比,接受IVT治疗的残疾患者恢复到基线功能的可能性更高(OR=7.26[95%CI,2.51-21.02])。死亡率和sICH率在接受IVT治疗的残疾患者和未接受治疗的患者之间没有明显差异。

同时,恢复到基线功能在有和没有卒中前残疾的患者之间没有明显差异(OR=1.46[95%CI,0.75-2.83])。有和没有病前残疾的患者的sICH发生率没有明显差异。然而,有病前残疾的患者的死亡率比没有病前残疾的患者高3倍(38.2%对12.6%)。

与未接受IVT的患者相比,残疾患者使用IVT与更好的结果有关,但没有统计学意义上的sICH或死亡风险增加。
