Abstract

The use of direct oral anticoagulants (DOACs) for the treatment and prevention of thromboembolic events has steadily increased. The DOACs offer an improved risk/benefit profile with regard to their comparable efficacy and decreased risk of bleeding compared to vitamin K antagonists. Despite their association with decreased risks of major bleeding, DOACs, as with all anticoagulant medications, put patients at risk of bleeding. Until recently, one advantage vitamin K antagonists possessed over DOACs was a drug-specific antidote to reverse their anticoagulant effects. The development of idarucizumab for dabigatran and andexanet alfa for rivaroxaban and apixaban has partially addressed this need. However, there is still no FDA-approved reversal agent for edoxaban or betrixaban. Furthermore, clinicians must consider key differences at the individual patient level regarding bleeding risk and management. The American College of Cardiology recently published a consensus decision pathway to help guide the management of oral anticoagulant-associated bleeding. This pathway is a useful tool in the management of DOACs, but the topic of DOAC-associated bleeding is a rapidly evolving topic, with new data becoming available, and further reversal agents in the pipeline.

Introduction

The Centers for Disease Control and Prevention (CDC) +-estimates that more than 900,000 venous thromboembolism (VTE) events, including deep vein thrombosis (DVT) and pulmonary embolism (PE), occur in the United States (US) annually. VTE is associated with high recurrence and mortality rate (60,000-100,000 Americans die from VTE each year).1 Additionally, approximately 2.7 million people in the US have nonvalvular atrial fibrillation (NVAF; see Sidebar, page 2) with the prevalence expected to grow to 12.1 million by 2030.2 Patients with atrial fibrillation are at an increased risk of stroke and systemic thromboembolic events.
