Background: Sex disparities in the association between epicardial adipose tissue volume (EATV) and cardiovascular disease have been reported. The sex-dependent effects of EATV on left atrial (LA) size have not been elucidated.
Methods: Consecutive 247 subjects (median 65 [interquartile range 57, 75] years; 67% of men) who underwent multi-detector computed tomography without significant coronary artery disease or moderate to severe valvular disease were divided into two groups: patients with sinus rhythm (SR) or atrial fibrillation (AF). Sex differences in the association between the EATV index (EATVI) (mL/m) and LA volume index (LAVI) in 63 SR (28 men and 35 women) and 184 AF (137 men and 47 women) patients were evaluated using univariate and multivariate regression analyses.
Results: In overall that includes both men and women, the relationship between EATVI and LAVI was not significantly correlated for patients with SR and AF. The relationship between EATVI and LAVI differed between men and women in both SR and AF groups. In SR patients, there was a positive relationship between EATVI and LAVI in men, but not in women. In contrast, in patients with AF, a negative relationship was found between EATVI and LAVI in women, whereas no association was found in men.
Conclusions: We evaluated sex differences in the association between EATVI and LAVI in patients with either SR or AF, and found a positive relationship in men with SR and a negative relationship in women with AF. This is the first report to evaluate sex differences in the relationship between EATVI and LAVI, suggesting that EAT may play a role, at least in part, in sex differences in the etiology of AF.

Background And Aims: The pathophysiologic concept of atrial fibrillation (AF) has evolved towards defining atrial cardiomyopathy, recognizing inflammation-mediated remodeling of the left atrium (LA) as a source for arrhythmogenesis. One feature of atrial cardiomyopathy is the development of fibrosis, with low-voltage zones (LVZ) identified by invasive electroanatomic mapping as an accepted surrogate parameter. A mediator of pathological remodeling is epicardial adipose tissue (EAT).

Purpose: The aim of this study was to explore the association of cardiac CT-based left atrium (LA) structural and functional parameters and left atrial epicardial adipose tissue (LA-EAT) parameters with postablation atrial fibrillation (AF) recurrence within 2 years.
Materials And Methods: Contrast-enhanced cardiac CT images of 286 consecutive AF patients (median age: 65 y; 97 females) who underwent initial ablation between June 2018 and June 2020 were retrospectively analyzed. Structural and functional parameters of LA, including maximum and minimum volume and ejection fraction of LA and left atrial appendage (LAA), and LA-EAT volume, were measured.

Atrial fibrillation (AF) is the most common arrhythmia and potentially increase the risk of embolic stroke and aggravate progressive heart failure in patients with hypertrophic cardiomyopathy (HCM). Recent studies demonstrated that epicardial adipose tissue (EAT) was closely associated with AF in general population. However, the relationship between EAT and AF in HCM patients remains unclear.
