Abstract
Objective
Studies have revealed that sex can predict differences in multiple aspects of atrial fibrillation (AF). These differences are underreported in the Middle East. This study aims to describe sex-specific differences in risk factors, symptomatology, management, and outcomes in Middle Eastern patients with AF.
Methods
The JoFib (Jordan-Atrial-Fibrillation) study is an observational, prospective, multicenter, nationwide registry in AF. Comparisons were made between female and male patients using Pearson chi-square and Mann-Whitney U tests. Multivariable regression models were constructed to investigate whether the female sex was predictive of any AF-related outcomes (all-cause death, cardiovascular death, ischemic stroke or systemic embolism [IS/SE], major bleeding, and clinically relevant non-major bleeding).
Results
Of 2,020 patients with AF, 54% (n = 1091) were females. Females with AF were older (median age 71 vs. 69, p <.001), but had less heart failure (20.9% vs. 27.2%, p = .001) and coronary artery disease (7.5% vs. 14.7%, p <.001). Females with AF were more symptomatic (74.7% vs. 66.5%, p <.001) and frequently received anticoagulant therapy (84.4% vs. 78.9%, p = .001). Rhythm control was pursued less frequently in females (23.4% vs. 27.3%, p = .04). All studied outcomes occurred with similar frequencies in females and males, and sex was not significantly predictive of any outcome.
Conclusion
Females with AF are more symptomatic, yet they are treated less with rhythm control. Despite higher risk, females have similar risk-adjusted all-cause cardiovascular death and stroke rates compared to males. Future studies should explore how treatments and interventions can influence quality-of-life and cardiovascular outcomes in females with AF.
