系统集中监测房颤,可有利于发现脑缺血事件

心房颤动与中风风险增加四至五倍有关,可能占全球每五次缺血性中风的比例。指南建议心房颤动患者(包括阵发性心房颤动患者)长期使用口服抗凝剂进行中风二级预防。然而,推荐给无心房颤动的缺血性卒中患者的血小板抑制剂,并不能使心房颤动患者的卒中风险明显降低。

两项大型随机研究显示,在未确定来源的栓塞性卒中(ESUS)患者中,使用利伐沙班或达比加群的抗凝疗法与阿司匹林相比没有优势。因此,心房颤动的诊断仍然是识别可从抗凝治疗中获益的卒中患者的先决条件,这适用于所有缺血性卒中亚型和存在其他风险因素的情况。

一些研究表明,长时间的心电图监测可提高缺血性卒中后隐蔽性心房颤动的检出率。然而,卒中后应进行多长时间的心电图监测,以及如何确保流动心电图监测的可行性尚不清楚。重要的是,没有已发表的随机研究能够评估长时间的心电图监测对抗凝剂使用的影响,或随后减少卒中患者的复发或死亡。

因此,标准化的缺血性脑卒中心房颤动监测的影响(MonDAFIS)研究旨在研究早期对住院患者进行长时间的系统性心电图监测与常规护理相比,在德国认证的卒中单位的可推广的临床环境下,对未选择的卒中幸存者队列的诊断率和治疗效果。


在这项由研究者发起的、随机的、开放标签的、平行分组的多中心研究中,柏林脑卒中研究中心的Karl Georg Haeusler等人,在德国38个经认证的卒中单位招募了至少18岁的急性缺血性卒中或短暂性缺血发作的患者,但不知晓有心房颤动。

患者被随机分配(1:1)接受常规的心房颤动检测诊断程序(对照组)或在医院进行长达7天的额外Holter-ECG记录(干预组)。患者按中心进行分层,采用随机排列的区块设计。主要结果是在指标事件发生后12个月,在有意治疗人群中使用口服抗凝剂的患者比例。

次要结果包括新诊断为心房颤动的住院患者人数,以及6个月、12个月和24个月后复发中风、大出血、心肌梗死或死亡的综合情况。


共3465名患者被随机分配,1735人(50-1%)被分配到干预组,1730人(49-9%)被分配到对照组。

2920名(84。3%患者在12个月时有口服抗凝状态(干预组1484名,对照组1436名)。就主要结果而言,在12个月时,干预组1484名患者中的203名(13-7%)与对照组1436名患者中的169名(11-8%)正在服用口服抗凝剂。

干预组1714人中有97人(5-8%)在住院期间新发现心房颤动,而对照组1717人中有68人(4-0%)新发现心房颤动。

24个月时,随机分配到干预组的患者与对照组的患者之间的血管结果和死亡的综合情况没有差别。

在干预组中,有56名(3-3%)患者因研究心电图电极而出现皮肤反应。干预组有73名(4-3%)患者发生全因死亡,对照组有103名(6-0%)患者发生全因死亡。

这个研究的重要意义在于:系统性核心集中进行(Systematic core centrally reviewed )心电图监测是可行的,可提高急性缺血性卒中或短暂性缺血发作住院患者的心房颤动检测率。然而,发现系统性心电图监测对12个月后口服抗凝剂的使用率没有影响,需要进一步努力提高二级卒中预防。
