Uninterrupted edoxaban vs. vitamin K antagonists for ablation of atrial fibrillation: the ELIMINATE-AF trial
Randomized controlled trial published in European heart journal (2019)
Abstract
AIMS: Edoxaban is a direct factor Xa inhibitor approved for stroke prevention in atrial fibrillation (AF). Uninterrupted edoxaban therapy in patients undergoing AF ablation has not been tested. METHODS AND RESULTS: The ELIMINATE-AF trial, a multinational, multicentre, randomized, open-label, parallel-group study, was conducted to assess the safety and efficacy of once-daily edoxaban 60 mg (30 mg in patients indicated for dose reduction) vs. vitamin K antagonists (VKAs) in AF patients undergoing catheter ablation. Patients were randomized 2:1 to edoxaban vs. VKA. The primary endpoint (per-protocol population) was time to first occurrence of all-cause death, stroke, or International Society of Thrombosis and Haemostasis-defined major bleeding during the period from the end of the ablation procedure to end of treatment (90 days). Overall, 632 patients were enrolled, 614 randomized, and 553 received study drug and underwent ablation; 177 subjects underwent brain magnetic resonance imaging to assess silent cerebral infarcts. The primary endpoint (only major bleeds occurred) was observed in 0.3% (1 patient) on edoxaban and 2.0% (2 patients) on VKA [hazard ratio (95% confidence interval): 0.16 (0.02-1.73)]. In the ablation population (modified intent-to-treat population including patients with ablation), the primary endpoint was observed in 2.7% of edoxaban (N = 10) and 1.7% of VKA patients (N = 3) between start of ablation and end of treatment. There were one ischaemic and one haemorrhagic stroke, both in patients on edoxaban. Cerebral microemboli were detected in 13.8% (16) patients who received edoxaban and 9.6% (5) patients in the VKA group (nominal P = 0.62). CONCLUSION: Uninterrupted edoxaban therapy represents an alternative to uninterrupted VKA treatment in patients undergoing AF ablation.

Summary
Edoxaban is a direct factor Xa inhibitor approved for stroke prevention in atrial fibrillation (AF).
Why This Matters for Hirudotherapy
The ELIMINATE-AF trial was a multinational, randomized study comparing uninterrupted edoxaban, a direct factor Xa inhibitor, to vitamin K antagonists in patients undergoing catheter ablation for atrial fibrillation. The study concluded that edoxaban represents a safe alternative to vitamin K antagonists. While the research deals with anticoagulation—a physiological process heavily targeted by leech secretions—it does not involve leeches or leech-derived therapeutics. Its relevance to the American Society of Hirudotherapy is limited to the broader clinical context of systemic anticoagulation management.
