2017年8月,发表在《Stroke》的一项由美国科学家进行的研究,考察了近期卒中患者中,溶栓治疗急性缺血性卒中的安全性结局。

背景和目的:尚不清楚既往3个月内发生缺血性卒中的患者接受静脉溶栓(tPA[组织型纤溶酶原激活剂])治疗急性缺血性卒中(AIS)是否与不良结局的风险增加相关。

方法:使用医保报销数据库(administrative claims data),研究者确定2005年至2013年期间在加利福尼亚、纽约和佛罗里达州的医院接受静脉tPA的成人AIS患者。主要结局指标为颅内出血,次要结局指标为不利的出院结局和院内死亡。研究者使用logistic回归,比较既往3个月内发生缺血性卒中的患者和无既往缺血性卒中患者静脉接受tPA治疗AIS的结局。

结果:研究者确定了36599例接受静脉tPA治疗的AIS患者,其中568例(1.6%)患者在过去3个月内发生缺血性卒中。在所有接受静脉tPA的患者中,颅内出血率为4.9%(95%置信区间[CI],4.7%~5.1%)、死亡率为10.7%(95% CI,10.4%~11.0%)。校正人口统计学因素、血管风险因素和Elixhauser并发症指数后,既往3个月内发生缺血性卒中患者溶栓治疗AIS与颅内出血风险增加不相关(比值比,0.9;95% CI,0.6~1.4;P=0.62),但与死亡(比值比,1.5;95% CI,1.2~1.9;P=0.001)和不利的出院结局(比值比,1.3;95% CI,1.0~1.7;P=0.04)风险增加相关。

结论:接受静脉tPA治疗AIS的患者中,近期发生缺血性卒中与颅内出血风险增加不相关,但与较高的死亡和不利出院结局风险相关。
