Ann Intern Med:用CHA2DS2-VASc作为抗凝标准存在不确定性

2018-09-27 xujing 中国循环杂志

《内科医学年鉴》上发表的一项研究显示,按照当前的指南建议,房颤患者依据CHA2DS2-VASc阈值启动抗凝治疗的临床净获益差异很大,质疑当前指南启动抗凝治疗的最佳CHA2DS2-VASc阈值。

《内科医学年鉴》上发表的一项研究显示,按照当前的指南建议,房颤患者依据CHA2DS2-VASc阈值启动抗凝治疗的临床净获益差异很大,质疑当前指南启动抗凝治疗的最佳CHA2DS2-VASc阈值。

目前,指南推荐在CHA2DS2-VASc评分≥2的患者中使用抗凝药物。

研究者指出,“在已发表的研究中,未接受抗凝治疗的房颤患者的卒中发生率差别很大。”

研究者调查了四个已发表的研究,包括ATRIA研究、丹麦国家患者登记队列研究、瑞典心房颤动队列研究和SPORTIF研究。

四项研究共纳入33,434例房颤患者,27,179例患者的CHA2DS2-VASc评分为2分以上。

研究者发现,在CHA2DS2-VASc评分≥2的患者中,华法林抗凝治疗的获益在不同的研究是不同的,ATRIA研究表明对卒中的益处最小。丹麦国家病例登记队列研究显示最大。

启动抗凝治疗的最佳CHA2DS2-VASc评分阈值在各研究中也各不相同。研究人员说,ATRIA研究使用CHA2DS2-VASc评分≥3,瑞典心房颤动队列研究采用CHA2DS2-VASc评分≥2,SPORTIF研究采用CHA2DS2-VASc评分≥1,丹麦国家病例登记队列研究采用CHA2DS2-VASc评分≥0。

研究者强调,目前基于CHA2DS2-VASc评分的指导方针可能需要修改,以便对缺血性卒中和严重出血的风险进行更准确、个性化的评估。

且指南应该明确,以CHA2DS2-VASc评分为启动抗凝治疗的主要依据存在不确定性。
