At a recent European cardiology meeting, a retrospective cohort study1 was presented which looked at differences in hospitalization rates for acute ischemic stroke among male and female patients with atrial fibrillation over a 15 year period (1998 – 2012). The study, which included 1.1 million patients admitted to 1000 hospitals in 46 states, revealed that women had a 23% higher risk of being hospitalized for stroke than men after adjusting for such risk factors as age, diabetes, hypertension, previous stroke and heart failure. In addition, women had a higher risk of stroke compared to men regardless of race, socioeconomic status, or geographic location. According to the study authors, “women have second-rate outcomes across the board due to inadequate stroke prevention care rather than biological differences”. Why should this be so?
A previously published, related study2 that evaluated over 500,000 Medicare patients (87% white, 41% male) after newly diagnosed atrial fibrillation found statistically significant differences in the receipt of appropriate medical services (e.g. evaluation by a cardiologist, catheter ablation, anticoagulation, use of beta blockers and antiarrhythmic drugs) - especially catheter ablation (female vs male: AHR 0.65; 95% CI 0.63-0.68; P < .001) and receipt of oral anticoagulants (female vs male: AHR 0.93; 95% CI 0.93-0.94; P < .001).
