Patients with atrial fibrillation (Afib) and stable coronary artery disease (CAD) have seen positive results with edoxaban (Savaysa) monotherapy, according to the EPIC-CAD trial. The study revealed that a 12-month composite of death, myocardial infarction, stroke, embolism, urgent revascularization, or bleeding events occurred less frequently in patients on edoxaban monotherapy compared to those on dual antithrombotic therapy. The significant difference in outcomes was driven by a decrease in bleeding events, with no notable variance in major ischemic events between the two groups.
At the European Society of Cardiology (ESC) meeting, Gi-Byoung Nam, MD, presented the findings of the study conducted at Asan Medical Center in Seoul, South Korea. The ESC session discussant, Marco Valgimigli, MD, PhD, emphasized the importance of the trial as the first study to evaluate dual versus single antithrombotic therapy exclusively in the context of an internationally approved direct oral anticoagulant (DOAC) regimen like edoxaban. The results align with existing ESC and American Heart Association/American College of Cardiology guidelines, advocating for oral anticoagulation alone following percutaneous coronary intervention (PCI) or acute coronary syndrome.
Valgimigli highlighted the relevance of the EPIC-CAD trial in shaping future treatment approaches for patients with CAD. While the transition from dual to single antithrombotic therapy remains a topic of discussion, the study’s evidence supports the use of edoxaban monotherapy to minimize bleeding risk without compromising ischemic event management. The investigation underscores the need for clinicians to reassess the rationale behind prescribing dual antithrombotic therapy and consider the potential benefits of a single-agent approach.
Although the EPIC-CAD trial provided valuable insights into the efficacy of edoxaban monotherapy, Valgimigli noted the complexity of interpreting the primary endpoint, particularly in the context of prior revascularization interventions. The study’s inclusion of a diverse patient population with varying lengths of stable CAD post-PCI or acute coronary syndrome further complicates the generalization of results. Additionally, the trial’s underpowered analysis of thrombotic events as a sole endpoint raises questions about the comprehensive assessment of treatment outcomes.
As medical professionals navigate the evolving landscape of antithrombotic therapy for patients with Afib and stable CAD, adherence to established guidelines and evidence-based practices becomes paramount. Valgimigli emphasized the importance of following existing recommendations and leveraging the robust evidence from trials like EPIC-CAD to guide treatment decisions. While the study’s focus on edoxaban monotherapy showcases promising results, ongoing research and real-world data will be essential in refining treatment strategies and optimizing patient care in this population.
The EPIC-CAD trial sheds light on the favorable outcomes associated with edoxaban monotherapy for patients with Afib and stable CAD. By prioritizing bleeding risk reduction and maintaining efficacy in managing ischemic events, this approach offers a compelling alternative to traditional dual antithrombotic therapy. Moving forward, healthcare providers must integrate these findings into clinical practice and continue to explore innovative treatment modalities that enhance patient outcomes and quality of life.
