Atrial fibrillation (Afib) and stable coronary artery disease (CAD) are two common conditions that often require antithrombotic therapy for management. A recent trial, EPIC-CAD, has shed light on the benefits of edoxaban (Savaysa) monotherapy compared to dual antithrombotic therapy in these patients. The study found that edoxaban monotherapy significantly improved net outcomes by reducing bleeding and ischemic events when compared to the standard dual therapy.
The results of the EPIC-CAD trial showed that patients on edoxaban monotherapy had a lower incidence of the composite endpoint of death from any cause, myocardial infarction, stroke, systemic embolism, unplanned urgent revascularization, or major bleeding. The difference in outcomes was mainly driven by a reduction in bleeding events, as there was no significant difference in the occurrence of major ischemic events between the two groups. This demonstrates the potential benefits of using edoxaban as a single agent in these patients.
The findings of the EPIC-CAD trial support the current guidelines from the European Society of Cardiology (ESC) and the American Heart Association/American College of Cardiology, which recommend oral anticoagulation alone for patients with CAD after percutaneous coronary intervention (PCI) or acute coronary syndrome. The results of this study, along with previous trials favoring single antithrombotic therapy over dual therapy, highlight the importance of reevaluating treatment strategies in these patient populations.
While the benefits of edoxaban monotherapy are clear, the timing of when to transition to a single agent after the early post-event period remains a challenge. Clinicians need to carefully assess the clinical justification for continuing dual antithrombotic therapy and consider the potential risks and benefits for each individual patient. Following the guidelines and evidence from trials like EPIC-CAD can help optimize treatment strategies and improve outcomes for patients with Afib and stable CAD.
It is important to note that the EPIC-CAD trial was underpowered for thrombotic events as a sole endpoint. Additionally, while the study included a significant number of Asian patients, the results may not be generalizable to all patient populations. Further research is needed to confirm the benefits of edoxaban monotherapy in a more diverse group of patients with Afib and stable CAD.
The EPIC-CAD trial provides valuable insights into the use of edoxaban monotherapy in patients with atrial fibrillation and stable coronary artery disease. The study’s findings support the potential benefits of using edoxaban as a single agent to improve outcomes and reduce bleeding events in this patient population. Clinicians should consider the evidence from this trial and follow the guidelines to optimize treatment strategies for these patients. Further research is needed to establish the long-term benefits and safety of edoxaban monotherapy in diverse patient populations.
