成人哮喘患者的心律失常
2012/12/24
摘要
目的:哮喘患者心律失常的致病原因尚未完全清楚。药物副作用,特别是β2受体激动剂的副作用可能在其中起到一定作用。本试验研究哮喘是否与心律失常风险和心电图显示的致心律失常特征相关,同时研究β2受体激动剂在哮喘患者心律失常中的作用。
方法:本项横断面研究入选158名成人哮喘患者和6303名非哮喘患者,所有受试者来自于荷兰乌得勒支健康项目的队列研究,后者为正在进行的、基于初级保健的纵向研究。所有患者接受全面检查,包括12导心电图检查和肺功能检查。主要转归为心电图上显示的任何心律失常(包括心动过速、心动过缓、室性早搏[PVC]、房颤或房扑)。次要转归为心动过速、心动过缓、PVC、房颤或房扑、平均心率、平均校正后的QT间期长度和延长的QT间期。
结果:哮喘患者心动过速和PVC(分别为3%和4%)发生率较非哮喘患者常见(0.6%, p<0.001; 2%, p=0.03)。QT间期延长的发生率在两者相似(哮喘:2%;非哮喘:3%;OR:0.6,95%CI:0.2-2.0)。74名采用β2受体激动剂治疗的哮喘患者中,心动过速和PVC更为常见(分别为OR: 12.4 [95% CI: 4.7-32.8]和3.7 [95% CI: 1.3-10.5])。
结论:心电图显示,与非哮喘患者相比,成人哮喘患者的心动过速和PVC更为常见。采用β2受体激动剂治疗的哮喘患者,其心动过速和PVC的风险增加。

Abstract
OBJECTIVE:The pathogenesis of cardiac arrhythmias in asthma patients has not been fully elucidated. Adverse drug effects, particularly those of β2-mimetics, may play a role. The aim of this study was to determine whether asthma is associated with the risk of cardiac arrhythmias and electrocardiographic characteristics of arrhythmogenicity (ECG) and to explore the role of β2-mimetics.
METHODS:A cross-sectional study was conducted among 158 adult patients with a diagnosis of asthma and 6303 participants without asthma from the cohort of the Utrecht Health Project-an ongoing, longitudinal, primary care-based study. All patients underwent extensive examinations, including resting 12-lead electrocardiogram (ECG) and pulmonary function tests. The primary outcome was "any arrhythmia on the ECG" (including tachycardia, bradycardia, premature ventricular contraction (PVC), and atrial fibrillation or flutter). Secondary outcomes were tachycardia, bradycardia, PVC, atrial fibrillation or flutter, mean heart rate, mean corrected QT (QTc) interval length, and prolonged QTc interval.
RESULTS:Tachycardia and PVCs were more prevalent in patients with asthma (3% and 4%, respectively) than those without asthma (0.6%, p < .001; 2%, p = .03, respectively). The prevalence of QTc interval prolongation was similar in participants with (2%) and without asthma (3%, odds ratio [OR]: 0.6 and 95% confidence interval [95% CI]: 0.2-2.0). In 74 asthma patients, who received β2-mimetics, tachycardia and PVCs were more common (OR: 12.4 [95% CI: 4.7-32.8] and 3.7 [95% CI: 1.3-10.5], respectively).
CONCLUSIONS:The adult patients with asthma more commonly show tachycardia and PVCs on the ECG than those without asthma. The patients with asthma received β2-mimetics; the risk of tachycardia and PVCs is even more pronounced.
