Women with atrial fibrillation in the Middle East: utilization of oral anticoagulant agents in a population with bad baseline clinical profiles and risk scores

Abstract

Abstract Background Atrial fibrillation (AF) is the most common sustained arrhythmia in women and men worldwide and in the Middle East. Several studies have shown that women with AF are undertreated despite worse baseline clinical and risk profiles compared with men. It is largely unknown if this also applies to Middle Eastern AF patients. Purpose To evaluate baseline clinical features and utilization of guideline-recommended oral anticoagulant medications (OACs) in Middle Eastern women with AF. Methods The Jordan AF prospective multicenter study enrolled 2160 patients with AF, including 1164 (53.9%) women, in 20 hospital and outpatient clinics (May 2019 through January 2021). Results Nonvalvular AF was present in 1038 (91.0%) of women and 935 (94.6%) of men. Compared with men, women were older (mean age 69.2±11.5 years vs. 66.1±14.9 years, p<0.001), and had higher prevalence of hypertension (79.1% vs. 69.5%, p<0.001), diabetes (46.1% vs. 41.7%, p=0.04) and obesity (60.5% vs. 34.6%, p<0.001). Women, however, had lower prevalence of two comorbidities; heart failure (21.5% vs. 28.6, p=0.001) and coronary artery disease (7.7% vs. 15.4%, p<0.001) compared with men. Rate of utilization of oral anticoagulant agents (OACs) was higher in women than men with high and intermediate CHA2DS2 VASc scores (Table). Direct OACs were used in 64.0% of women and 63.3% of men with high risk score (p=NS). Multivariate analysis did not show sex to be an independent predictor of use of OACs. Conclusions Middle Eastern women with AF have worse baseline clinical and risk score profiles compared with men. In disagreement with other regional studies, the majority of these women received guideline-recommended OACs. Funding Acknowledgement Type of funding sources: None.
