Abstract
BACKGROUND AND OBJECTIVES: Gender-related differences in health care utilization for atrial fibrillation (AF) are increasingly recognized. However, large cohort data for examining gender-related differences in AF are lacking in Asian populations. METHODS: The Registry for Comparison Study of Drugs for Symptom Control and Complication Prevention of AF (CODE-AF Registry) is a prospective observational cohort-study that enrolled participants at 10 tertiary hospitals in South Korea. Baseline characteristics retrieved from the CODE-AF Registry were analyzed. RESULTS: A total of 6,274 patients were recruited (mean age 67±11 years, mean CHA₂DS₂-VASc score 2.7±1.7, 63% male, 65% paroxysmal AF) from June 2016 to April 2017. Women underwent less electric cardioversion (12.3% vs. 19.6%, p<0.001), less radiofrequency ablation (12.4% vs. 17.9%, p<0.001), and less antiarrhythmic drug therapy (44.7% vs. 49.5%, p<0.001), despite having more severe symptoms (symptom class III or IV, 45.8% vs. 37.5%, p<0.001). Among patients with a CHA₂DS₂-VA score of 2 or more, a slightly higher proportion of women were taking oral anticoagulants than men (85.7% vs. 81.9%, p=0.002), and non-vitamin K antagonist oral anticoagulant (NOAC) use was more prevalent in women than men (70.4% vs. 62.3%, p<0.001). Insufficient NOAC dosing was very common, more so in women than men (61.5% vs. 56.3%, p<0.001). CONCLUSIONS: Female patients with AF were treated more conservatively and rhythm control strategies were used less frequently than in males, even though the female patients with AF had more severe symptoms. While insufficient NOAC dosing was common in both sex, it was significantly more frequent in women.
