JAHA:房颤与早发性痴呆风险

2022-07-17 MedSci原创 MedSci原创

AF是70岁以下成人痴呆的一个危险因素,提示在65岁以下人群中已经存在轻微的、统计上不精确的额外风险。

房颤(AF)是世界范围内临床最常见的重要心律失常。它的特点是心房的快速和不规则的兴奋,当混乱的电活动取代正常的窦机制时发生。AF与死亡率和发病率增加相关,包括卒中风险增加5倍,是卫生保健成本增加的主要原因。最近的研究发现,AF患者发生痴呆症的风险增加。然而,AF和痴呆通常在晚年才出现。很少有研究在成人早发性痴呆中调查这种关联。

近日,心血管疾病领域权威杂志JAHA上发表了一篇研究文章,该研究的目的是探究AF与早发性痴呆之间的关系。

研究人员检索了PubMed/MEDLINE、Embase和Scopus数据库,直到2022年4月15日,以寻找70岁以下成年人AF和痴呆之间关联的研究。两名研究人员独立进行研究选择,评估偏倚风险,并提取研究数据。研究人员使用随机效应模型对早发性痴呆风险进行Meta分析。

研究人员检索并筛选了1006项可能符合条件的研究,并审查了33项研究的全文,最终选择了6项符合纳入标准的研究。该研究的结果汇总分析显示,AF患者发生痴呆的风险增加,年龄<70岁的患者总体相对风险为1.50(95%CI为1.00-2.26),年龄<65岁的患者总体相对风险为1.06(95%CI为0.55-2.06)。

在这项系统综述和荟萃分析中,AF是70岁以下成人痴呆的一个危险因素,提示在65岁以下人群中已经存在轻微的、统计上不精确的额外风险。需要进一步的研究来评估心律失常的特征以及在这一关系中发挥作用的机制。
