Premature ventricular contraction (PVC) and atrial fibrillation (AF) are common arrhythmias affecting 1–2% of the general population. During PVC, retrograde ventriculo-atrial activation can occur and act like an atrial ectopy. However, the clinical significance of this phenomenon is not fully understood. We aimed to elucidate whether the clinical diagnosis of PVC can increase the risk of new-onset AF. We performed a nationwide population-based analysis using the Korean National Health Insurance Service database. A total of 9,537,713 people without prior history of PVC and AF were identified. Among these people, 4135 developed PVC in 2009, and people with and without PVC were followed until 2018. People who had PVC showed an increased risk of new-onset AF as compared with people without PVC (hazard ratio [HR] = 2.705; 95% confidence interval [CI] = 2.428–3.013; p < 0.001). The risk of ischemic stroke was also significantly increased in people with PVC (HR 1.160; 95% CI 1.048–1.284; p = 0.0041). New-onset AF developed in 72 people (19.3%) among 374 people with PVC who had ischemic stroke during their follow-up. A significant interaction was observed between PVC and age with people < 65 years at greater risk of new-onset AF for having PVC. In this observational analysis, the risk of new-onset AF and ischemic stroke was increased in people with PVC. Additional evaluation to identify AF in people with PVC can be helpful.

室性早搏与心房颤动风险增加有关:一项全国性的基于人群的研究

室性早搏 (PVC) 和心房颤动 (AF) 是常见的心律失常,影响 1-2% 的普通人群。在 PVC 期间,可能会发生逆行心室 - 心房激活并像心房异位症一样起作用。然而,这种现象的临床意义尚不完全清楚。我们旨在阐明 PVC 的临床诊断是否会增加新发 AF 的风险。我们使用韩国国民健康保险服务数据库进行了全国人口分析。共确定了 9,537,713 名无 PVC 和 AF 既往史的人。在这些人中,2009 年有 4135 人发生了 PVC,对有和无 PVC 的人进行了随访至 2018 年。与没有 PVC 的人相比,有 PVC 的人新发 AF 的风险增加(风险比 [HR] = 2.705;95% 置信区间 [CI] = 2.428–3.013;p < 0.001)。PVC 患者的缺血性卒中风险也显着增加(HR 1.160;95% CI 1.048–1.284;p = 0.0041)。在随访期间发生缺血性卒中的 374 名 PVC 患者中,有 72 人(19.3%)出现新发房颤。观察到 PVC 与年龄之间存在显着的交互作用,年龄 < 65 岁的人因 PVC 患新发 AF 的风险更大。在这项观察性分析中,PVC 患者新发 AF 和缺血性卒中的风险增加。额外评估以识别 PVC 患者的 AF 可能会有所帮助。3%)在 374 名 PVC 患者中,他们在随访期间发生了缺血性卒中。观察到 PVC 与年龄之间存在显着的交互作用,年龄 < 65 岁的人因 PVC 患新发 AF 的风险更大。在这项观察性分析中,PVC 患者新发 AF 和缺血性卒中的风险增加。额外评估以识别 PVC 患者的 AF 可能会有所帮助。3%)在 374 名 PVC 患者中,他们在随访期间发生了缺血性卒中。观察到 PVC 与年龄之间存在显着的交互作用,年龄 < 65 岁的人因 PVC 患新发 AF 的风险更大。在这项观察性分析中,PVC 患者新发 AF 和缺血性卒中的风险增加。额外评估以识别 PVC 患者的 AF 可能会有所帮助。
