Stroke:来源不明的栓塞性卒中患者大出血发生频率和预测因素

2020-06-10 MedSci原创 MedSci原创

在这项来源不确定栓塞性卒中患者的国际随机试验中,大出血的独立预测因素是利伐沙班、东亚国家、收缩压升高和肾功能受损。东亚地区与脑出血的风险密切相关。估计的肾小球滤过率应考虑作为区分出血风险的因素。

对于来源不明的栓塞性卒中患者,抗栓治疗期间发生大出血的风险、部位和预测因素尚未明确。

近日,血管疾病领域权威杂志Stroke上发表了一篇研究文章,研究人员对国际NAVIGATE(利伐沙班抑制因子Xa新方法的全球试验)中7213名未确定来源的栓塞性卒中患者进行了国际血栓形成和止血标准定义的大出血探索性分析,该随机试验比较了每日15 mg利伐沙班和阿司匹林100 mg的疗效。

在11个月的中位随访期间,受试者发生了85次大出血。最常见的部位是胃肠道(38%),其次是颅内(29%)。给予利伐沙班治疗(风险比[HR]为2.7 [95%CI为1.7-4.3])、东亚国家(HR为2.5 [95%CI为1.6-3.9])、收缩压≥160mmHg(HR为2.2 [95%CI为1.2-3.8]和肾小球滤过率降低(每降低10mL/min/1.73m2的HR为1.2,[95%CI为1.0-1.3])与大出血独立相关。5人(6%)发生死亡。在15例脑出血患者中,有2例(13%)死亡。没有证据表明利伐沙班治疗后进入早高危期。东亚国家参与者脑出血的年化率(0.67%)是所有其他地区(0.11%;HR为6.3 [95%CI为2.2-18.0])的六倍。利伐沙班和阿司匹林的出血部位分布相似。

在这项来源不确定栓塞性卒中患者的国际随机试验中,大出血的独立预测因素是利伐沙班、东亚国家、收缩压升高和肾功能受损。东亚地区与脑出血的风险密切相关。估计的肾小球滤过率应考虑作为区分出血风险的因素。
