JAHA:儿童心动过缓与老年房室传导缺陷相关

2021-09-26 MedSci原创 MedSci原创

儿童心动过缓与老年房室传导缺陷几率升高两倍相关,其中88%是良性的。此外,它不会影响死亡率或心脏大小及功能。未来的研究应该集中在识别有风险的儿童上。

近日,血管疾病领域权威杂志JAHA上发表了一篇研究文章,该研究旨在使用1946年全国健康与发展调查(NSHD)出生队列的纵向数据,探讨了儿童心动过缓与晚年心脏表型之间的关联。

研究人员记录了受试者6岁和7岁时的静息心率,以获得儿童静息心率<75bpm的心动过缓暴露。研究人员分析了三个结局:(1)60至64岁的超声心动图数据,包括射血分数、左心室质量指数、心肌收缩分数指数和E/e';(2)60至64岁有房室或心室传导缺陷的心电图证据;(3)全因死亡率和心血管死亡率。研究人员使用广义线性模型或Cox回归模型进行分析,并针对相关人口统计学和健康相关协变量以及多重检验进行调整。混合广义线性模型和分数多项式被用于敏感性分析。

三分之一患有房室传导缺陷的老年人在儿童时期有过心动过缓,其中12%的患者有严重缺陷(MobitzII型二度或更高的房室传导阻滞)。在完全调整的模型中,儿童心动过缓与房室传导缺陷的几率高出2.91倍(95%CI为1.59-5.31;P=0.0005)相关。

关联在随机系数混合广义线性模型中持续存在(比值比为2.50;95%CI为1.01–4.31)。分数多项式证实了60至64岁房室传导缺陷的对数几率与7岁静息心率之间的线性关联。儿童心动过缓与死亡率结局或超声心动图参数和老年房室传导缺陷之间没有关联。

这项纵向出生队列数据表明,儿童心动过缓与老年房室传导缺陷几率升高两倍相关,其中88%是良性的。此外,它不会影响死亡率或心脏大小及功能。未来的研究应该集中在识别有风险的儿童上。
