Abstract P002: Gender Differences in Atrial Fibrillation Hospitalizations
Background: While there are recognized gender differences in cardiovascular disease, little is known regarding the role of gender in atrial fibrillation (AF). We therefore sought to determine differences in characteristics of AF hospitalization between men and women.
Methods: Data from the 2009-2010 Healthcare Cost and Utilization Project were used to model AF hospitalizations as a function of patient age and gender.
Results: Of 192,846 AF hospitalizations, 50% of patients were female. Mean age was 74 years versus 66 years for men. Figure I shows AF hospitalizations stratified by age and gender. Women were less likely than men to have diabetes (24 vs 25%, p<0.001), chronic kidney disease (11.2 vs 12.2%, p<0.001), and obesity (12.2 vs 12.9%, p<0.001). They were more likely to have a history of stroke (2.0 vs 1.7%, p<0.001), hypertension (68.7 vs 62.5%, p<0.001), and depression (9.6 vs 5.4%, p<0.001). Females were more likely to be admitted from the emergency room (72.9 vs 66.6%, p<0.001), were hospitalized longer (mean days 3.6 vs 3.3, p<0.001), and were more likely to be discharged to a skilled nursing facility (10.1 vs 4.5%, p<0.001). Women were less likely to have an electrical cardioversion (12.4 vs 18.4%, p<0.001) or AF ablation performed (5 vs 10%, p<0.001) and had a higher mortality than men (0.95 vs 0.75%, p<0.001).
Conclusion: Women are hospitalized with AF later in life than men, with the greatest burden in female octogenarians. There is a high prevalence of depression among this cohort. While they have fewer comorbidities, women appear to be more symptomatic from AF and more debilitated upon discharge. Despite this, women are less likely than men to have procedures commonly used to treat AF and are more likely to die during hospitalization.
