2017年4月,发表在《Stroke》的一项由以色列科学家进行的研究考察了国家急性脑卒中登记(国家急性脑卒中以色列调查[NASIS])9年数据中,急性脑缺血合并房颤患者抗凝药的使用中,风险和回报的认知转变。

背景和目的:尽管强有力的证据证明脑缺血合并房颤患者使用抗凝药的获益,但也有大量使用不足的报告。

方法:评价国家急性脑卒中以色列调查登记(NASIS)中,房颤合并急性脑缺血住院患者使用抗凝药物进行卒中二级预防的情况。通过Logistic回归分析,评价临床协变量对出院时抗凝治疗的影响,并在有确定抗凝药物使用障碍的患者亚组中,评价抗凝药物的使用情况。

结果:纳入1254例急性脑缺血合并房颤的幸存者(平均年龄77.2±10.6岁;57.7%为女性)。2004年至2013年,出院使用抗凝药的患者比例从55%增加至76.2%,而没有禁忌症的患者出院使用抗凝药的比例从70%增加至96%(P<0.0001)。高龄、卒中严重程度较高、较早注册和出现禁忌症是治疗不能持续的独立预测因素。在过去的几年里,甚至在有抗凝药使用障碍,包括有潜在禁忌症的患者中,观察到了抗凝药使用的增加(P<0.0001)。

结论:在脑缺血合并房颤的幸存者中,研究者观察到了在不到10年内,抗凝药使用大幅增加。这一变化主要由于抗凝药使用存在传统临床障碍的亚组更多地使用抗凝药,提示医师对抗凝药的风险-获益比认知的转变。
