JAHA:心房疾病相关的痴呆风险

2022-08-11 MedSci原创 MedSci原创

心房疾病与痴呆风险增加显著相关,只有很小比例的效应由房颤或卒中介导。

房颤(AF)与独立于临床卒中的认知障碍发展相关。一项纳入了80000名以上房颤患者的荟萃分析数据表明即使没有卒中,房颤也可能独立导致认知障碍。心房疾病对痴呆风险的作用尚未明确。

近日,心血管疾病领域权威杂志JAHA上发表了一篇研究文章,研究人员的目的是评估心房疾病与痴呆事件之间的关系,以及AF和卒中的潜在介导作用。

研究人员对社区动脉粥样硬化风险(ARIC)研究参加第5次随访(2011-2013)的参与者进行了前瞻性队列分析,并使用Cox回归来确定心房疾病与痴呆风险之间的关联。结构方程建模方法用于确定AF和/或卒中的潜在介导作用。如果在第5次随访时满足以下1项以上,则判定为心房疾病:ECG导联V1P波终末力>5000mV·ms,脑利钠肽前体N末端(NT‐proBNP)>250pg/mL或经胸超声心动图确定的左房容积指数≥34mL/m2。研究人员重复了该研究的分析,需要2个以上的指标来定义心房疾病。

在5078名参与者中(平均年龄为75岁,59%为女性,21%为黑人成年人),心房疾病的患病率为34%,其中763名参与者发展为痴呆症。心房疾病与痴呆显著相关(调整后的HR为1.35[95%CI为1.16-1.58]),当需要≥2个生物标志物时,效果评估增强(调整后的HR为1.54[95%CI为1.25-1.89])。当排除房颤(校正HR为1.31[95%CI为1.12-1.55])或卒中(校正HR为1.28[95%CI为1.09-1.52])时,房颤患者发生痴呆的风险增加。房颤介导的比例为4%(P=0.005),脑卒中介导的比例为9%(P=0.048)。

由此可见,心房疾病与痴呆风险增加显著相关,只有很小比例的效应由房颤或卒中介导。
