Abstract | BACKGROUND: Anticoagulation is often avoided in patients with atrial fibrillation who are at an increased risk of falling. OBJECTIVES: METHODS: We performed a pre-specified analysis of the ENGAGE AF-TIMI 48, comparing patients with versus without increased risk of falling. RESULTS: Nine hundred patients (4.3%) were judged to be at increased risk of falling. These patients were older (median, 77 vs. 72 years; p < 0.001), and had a higher prevalence of comorbidities including prior stroke/ transient ischemic attack, diabetes, and coronary artery disease. After multivariable adjustment, patients at increased risk of falling experienced more bone fractures caused by falling (adjusted hazard ratio [HRadj]: 1.88; 95% confidence interval [CI]: 1.49 to 2.38; p < 0.001), major bleeding (HRadj: 1.30; 95% CI: 1.04 to 1.64; p = 0.023), life-threatening bleeding (HRadj: 1.67; 95% CI: 1.11 to 2.50; p = 0.013), and all-cause death (HRadj: 1.45; 95% CI: 1.23 to 1.70; p < 0.001), but not ischemic events including stroke/systemic embolic event (HRadj: 1.16; 95% CI: 0.89 to 1.51; p = 0.27). No treatment interaction was observed between either dosing regimens of edoxaban and warfarin for the efficacy and safety outcomes. Treatment with edoxaban resulted in a greater absolute risk reduction in severe bleeding events and all-cause mortality compared with warfarin. CONCLUSIONS:
Edoxaban is an attractive alternative to warfarin in patients at increased risk of falling, because it is associated with an even greater absolute reduction in severe bleeding events and mortality.
