Abstract

Purpose

Although direct oral anticoagulants are effective and safe in preventing stroke in atrial fibrillation (AF) patients with low body weight, data remain limited in AF patients with extremely low body weight (<50 kg). We aimed to investigate the association of this body weight category with clinical outcomes in elderly AF patients receiving apixaban.

Methods

The J-ELD AF Registry is a large-scale, multicenter prospective observational study of Japanese non-valvular AF patients aged ≥ 75 years taking on-label doses of apixaban. The entire cohort (3025 patients from 110 institutions) was divided into three body weight subgroups: >60 kg (n = 1019, 33.7%), 50–60 kg (n = 1126, 37.2%), and <50 kg (n = 880, 29.1%).

Results

The event incidence rates (/100 person years) were 1.69, 1.82, and 1.23 for stroke or systemic embolism (P = 0.60); 1.37, 1.73, and 2.73 for bleeding requiring hospitalization (P = 0.154); 2.02, 2.67, and 4.92 for total death (P = 0.003); and 0.73, 0.95, and 1.23 for cardiovascular death (P = 0.57), respectively. After adjusting for confounders by Cox regression analysis, body weight <50 kg was not an independent risk for stroke or systemic embolism, bleeding requiring hospitalization, total death, or cardiovascular death.

Conclusions

The incidence of events in each body weight group was comparable for stroke or systemic embolism and bleeding requiring hospitalization, and body weight <50 kg might not be an independent risk for death in Japanese non-valvular AF patients aged ≥ 75 years taking on-label doses of apixaban.
