Abstrakt: Background: Atrial fibrillation (AF) has emerged as a notable public health issue in China due to the aging population and rapid urbanization. This study aimed to describe the characteristics of patients with AF (paroxysmal and nonparoxysmal) and investigate the association between left ventricular ejection fraction (LVEF) levels and AF subtypes to facilitate early prevention in patients with AF.
Method: Patients with AF who presented at the cardiology department of the First People's Hospital of Yancheng were recruited in this study. In univariate and multivariate logistic regression analyses, odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to evaluate the relationships between each dependent variable and nonparoxysmal AF. The restricted cubic splines (RCS) curve was employed to explore the linear relationship between LVEF and nonparoxysmal AF on a continuous scale. Subgroup analysis was applied to examine the stability of the results.
Results: The study included a total of 2054 patients who were diagnosed with AF. 652 (31.74%) patients had paroxysmal AF, and 1402 (68.26%) had nonparoxysmal AF. Multivariate logistic regression analyses indicated that compared to those with paroxysmal AF, patients with nonparoxysmal AF tended to have a higher prevalence of coronary artery disease, lower levels of LVEF, and an elevated heart rate. Additionally, RCS curves also showed that LVEF was negatively and linearly associated with the nonparoxysmal AF. Furthermore, the association between LVEF and nonparoxysmal AF was stronger among patients with hypertension and obesity (P for interaction < 0.05).
Conclusions: Patients with nonparoxysmal AF have a more advanced AF burden and the transition from paroxysmal to nonparoxysmal AF should be recognized in time, especially to treat the corresponding comorbidities (including hypertension and obesity) more consistently.
