Stroke:小剂量替罗非班治疗可改善静脉溶栓后神经系统恶化结局

2019-10-02 xing.T MedSci原创

由此可见,早期神经系统恶化的患者在IVT后的最初24小时内使用小剂量替罗非班不会增加症状性颅内出血、ICH和死亡率的风险,其与3个月时的神经功能改善有关。需要进一步的随机临床试验来验证这些结果。

静脉溶栓(IVT)后24小时内尽早使用抗血小板药物一直是一个令人困惑的临床问题。近日,心血管疾病领域权威杂志Stroke上发表了一篇研究文章,该研究旨在评估早期神经系统恶化(END)患者IVT后24小时内早期低剂量替罗非班治疗的安全性和疗效。

该研究是对2017年1月至2018年9月期间连续就诊的1764例接受IVT治疗的急性缺血性卒中患者收集的前瞻性数据进行的回顾性分析。在IVT后的最初24小时内出现早期神经功能恶化的患者接受或不接受替罗非班治疗,该研究安全性结局包括症状性颅内出血、任何ICH、严重的全身性出血和死亡率。疗效结局包括极好的(改良的Rankin量表评分为0–1)和良好的(改良的Rankin量表评分为0–2)3个月的功能结局。

278名(15.8%)患者发生了早期神经功能恶化。在187名符合条件的患者中,121例(64.7%)患者在IVT后的最初24小时内接受了替罗非班治疗。校正后的多变量分析显示,早期使用替罗非班与症状性颅内出血(校正比值比[aOR]为1.05; 95%CI为0.088-11.02; P=1.000)、ICH(aOR为1.13;95%CI为0.45–4.25;P=0.512)和死亡率(aOR为0.77;95%CI为0.19–2.27;P=0.875)无关,但与极好(aOR为2.24;95%CI为1.16-3.94;P=0.027)和良好(aOR为2.31;95%CI为1.48-3.99;P=0.011)的功能结局显著相关。亚组分析表明,早期使用替罗非班的疗效是时间依赖性的,在更早接受替罗非班治疗的患者中更有效。

由此可见,早期神经系统恶化的患者在IVT后的最初24小时内使用小剂量替罗非班不会增加症状性颅内出血、ICH和死亡率的风险,其与3个月时的神经功能改善有关。需要进一步的随机临床试验来验证这些结果。
