Female gender was included in stroke prediction algorithms in an attempt to improve anticoagulation rates in women with atrial fibrillation (AF). It is unclear if these efforts reduced stroke burden in women with AF. To bridge this literature gap, using the Nationwide Inpatient Sample, we assessed gender differences in the trends of hospitalizations for stroke among patients with AF in the United States in 2005 to 2014. International classification of diseases, 9th revision, clinical modification codes were used to abstract AF and stroke diagnoses. From 2005 to 2014, 18,413,291 hospitalizations of women with AF and 18,035,866 hospitalizations of men with AF were reported. Of these, 740,635 hospitalizations in women and 595,730 hospitalizations in men had stroke as the primary diagnosis. Age-adjusted stroke hospitalizations increased in women (443 per million in 2005 to 495 per million in 2014) as well as in men …
