Neurology:维生素K拮抗剂增加脑出血复发风险

2014-03-05 辛夷籽 丁香园

脑出血后,如何进行抗凝治疗,是临床上亟待解决的问题。来自意大利佛罗伦萨大学careggi医院的Daniela Poli博士及其合作者,对有脑出血病史的患者使用vk拮抗剂(VKAs)抗凝治疗后复发脑出血的风险进行了评估,结果在线发表在2月21日的Neurology杂志上。这是一项脑出血患者重启口服抗凝剂治疗研究(CHIRONE Study),收集了隶属于意大利抗凝门诊联盟(FCSA)的27个数据库中

脑出血后,如何进行抗凝治疗,是临床上亟待解决的问题。来自意大利佛罗伦萨大学careggi医院的Daniela Poli博士及其合作者,对有脑出血病史的患者使用vk拮抗剂(VKAs)抗凝治疗后复发脑出血的风险进行了评估,结果在线发表在2月21日的Neurology杂志上。

这是一项脑出血患者重启口服抗凝剂治疗研究(CHIRONE Study),收集了隶属于意大利抗凝门诊联盟(FCSA)的27个数据库中符合资格的病人数据。

该研究共纳入了267名在首次脑出血后使用vk拮抗剂进行抗凝治疗的患者(163名男性,中位年龄73.9岁)。在总随访期内,20名患者在16.5个月的中位时间复发脑出血(7.5%),其中5例的复发为致命性的(25%)。男性、高血压、人工心脏瓣膜置换、既往缺血性卒中病、肾衰、癌症及自发事件均和复发脑出血的风险相关,尽管这些因素单独作用时均无统计学意义。多于1/3的自发性复发患者与创伤事件有关。

研究显示有脑出血病史的患者使用vk拮抗剂进行抗凝治疗时,复发脑出血的风险显著增高。发生过创伤事件的患者也会有复发脑出血的风险,但是关联程度较低。临床上对于有脑出血病史的患者要认真进行血栓栓塞风险评估,从而对使用vk拮抗剂抗凝带来的临床收益及风险进行权衡。
