Heart:手机的新功能——筛查房颤

2016-11-12 xing.T MedSci原创

智能手机为基础的无线单导联心电图对社区进行房颤患者筛查是可行的,它发现了大部分新诊断为房颤的居民,在中国香港人群中房颤的患病率与当代西方相当。除了年龄和性别外,不同的人体测量参数和心血管疾病被确定为房颤的独立预测因子。

近日,在心脏病领域权威杂志Heart上发表了来自中国香港玛格丽特公主医院老年病科Ngai-yin
Chan博士及其研究团队的文章,旨在评估利用智能手机为基础的无线单导联心电图对社区进行房颤患者筛查的可行性,并收集了香港房颤患者及其危险因素的流行病学资料。

在2014年5月1日至2015年4月30日期间,共有13,122名香港市民自愿参加全港社区房颤筛查方案。研究人员发现除了有56(0.4%)名参与者智能手机为基础的无线单导联心电图结果是无法解释的外,有101(0.8%)名参与者被首次诊断为房颤患者,其中有66(65.3%)名新诊断患者为无症状房颤。新诊断房颤参与者的CHA2DS2VASC评分[即充血性心力衰竭、高血压、年龄> 75(双倍)、糖尿病、脑卒中(双倍)、血管性疾病、年龄在65岁–74岁、性别(女性)评分]为3.1±1.3分。研究者发现智能手机为基础的无线单导联心电图检测到的房颤患病率为1.8%,而通过手机为基础的无线单导联心电图检测到的房颤或参与者自我报告的房颤患病率为8.5%。采用多因素Logistic回归分析,研究者发现能够独立预测房颤的因素包括年龄、性别、身高、体重、体重指数、心衰、瓣膜性心脏病、中风、高脂血症、冠心病、外周动脉疾病和心胸外科手术病史。

由此可见,智能手机为基础的无线单导联心电图对社区进行房颤患者筛查是可行的,它发现了大部分新诊断为房颤的居民,在中国香港人群中房颤的患病率与当代西方相当。除了年龄和性别外,不同的人体测量参数和心血管疾病被确定为房颤的独立预测因子。
