Chest:老年人右心室后负荷与房颤风险的关系

2022-05-26 MedSci原创 MedSci原创

在老年人群中,较高的右心室后负荷与较大的房颤风险相关,而不依赖于左心房和左室重构。未来的研究应集中于证实这种新的关联,并阐明其潜在机制。

房颤被广泛认为发病起源于左心房。但目前尚不清楚老年人右心室后负荷的增加是否在房颤发病机制中发挥作用,并独立于左心室重构。

近日,呼吸领域权威杂志chest上发表了一篇研究文章,该研究旨在明确较高的右心室后负荷是否与较大的房颤风险相关,且不依赖于左心房和左心室重构。

在这项前瞻性观察研究中,研究人员纳入了2246名居住在社区的老年人(平均年龄为75岁),他们既往没有已知的心血管疾病,左室射血分数>50%,左心房体积指数<34ml/m2,E/E'比值<14,三尖瓣功能性反流射流速度数据可用。研究人员通过二维超声心动图检查估计了受试者的肺动脉收缩压(PASP)和肺血管阻力(PVR)。此外,研究人员从医院出院代码和死亡证明中确定了受试者突发房颤(截至2018年)情况,并通过Cox回归估计了风险比(HR)。

在随访期间(平均为6.3年,四分位数为5.5-6.9年),215名参与者发生房颤。第3分位数与第一分位数PASP(HR为1.65,95%可信区间(CI)为1.08-2.54)和PVR(HR1.38,95%置信区间1.00-2.08)相比房颤风险明显升高,且独立于左心房和左心室结构和功能,心率、体重指数、睡眠呼吸暂停、血压、降压药物、肺脏、肾脏和甲状腺功能。进一步排除三尖瓣反流射流速度>2.8m/s和二尖瓣环外侧和间隔速度超过年龄和性别参考范围的参与者后,这些相关性仍然存在。

由此可见,在老年人群中,较高的右心室后负荷与较大的房颤风险相关,而不依赖于左心房和左室重构。未来的研究应集中于证实这种新的关联,并阐明其潜在机制。
