One-Year Outcome of Japanese Patients With Atrial Fibrillation: Insights From APHRS-AF Registry.
The Asia-Pacific Heart Rhythm Society Atrial Fibrillation (APHRS-AF) Registry is a prospective study in Asian metropolitan cities, which provides important information on the baseline characteristics, therapeutic patterns, and 1-year clinical outcomes in patients with atrial fibrillation (AF). This report describes data from Japanese patients recruited in this registry.
A total of 4666 patients with AF were enrolled. Of these, 794 patients were recruited from 28 large cardiovascular centers in Japan between 2015 and 2017. We analyzed 1-year follow-up outcome of these patients. Mean age at recruitment was 65.7 years and 69.0% were males. Major comorbidities were hypertension (37.5%), lipid disorder (29.0%), heart failure (15.9%), and diabetes mellitus (15.0%). Mean CHADS2 score, CHA2DS2-VASc score, and HAS-BLED score were 1.0, 2.0, and 1.1, respectively. At baseline, use of oral anticoagulants was 81%, including 7% prescribed a vitamin K antagonist (VKA) and 74% a direct oral anticoagulant (DOAC). Majority of the patients (N = 459, 57.8%) were planned to undergo catheter ablation. One-year follow-up was conducted in 743 patients. One-year all-cause mortality was 0.1% (n = 1) and the incidence of stroke/thromboembolic events was also 0.1% (n = 1). Major bleeding events were observed in 5 patients (0.7%), including 3 intracranial hemorrhages.
In this 1-year analysis, a high prevalence of oral anticoagulant use was recorded. A low mortality rate and a low incidence of stroke/thromboembolic events were observed in Japanese patients of the APHRS-AF Registry.
