Abstract:
Background: Bleeding is the most important complication associated with anticoagulants. Patients experiencing bleeding while on an anticoagulation require proper risk stratification, which involves careful assessment of multiple factors, including hemodynamic stability, the origin of bleeding, and the extent of blood loss. Over the last several decades, important advances have been made in the field of anticoagulant therapy and reversal.
Objectives: This manuscript provides a review of anticoagulant related hemorrhages, with particular emphasis on topics most relevant to Latin America. It offers an updated assessment of evidence-based strategies for managing major bleeding related to anticoagulation. We will also explore what happens to patients in real-life situations, where there are not specific reversal agents available.
Discussion: While minor bleeding can usually be managed simply by discontinuing the anticoagulant, major bleeding is a medical emergency that may threaten life and require the administration of blood products and the utilization of specific antidotes. Fresh frozen plasma (FFP) or prothrombin complex concentrates (PCCs) can be administrated for major bleeding incidents linked to warfarin. Protamine sulfate is administrated for unfractionated heparin and partially for low-molecular-weight heparin (LMWH). Idarucizumab is the reversal agent for dabigatran, while andexanet alfa is approved for the reversal of oral factor Xa inhibitors.
Conclusions: This review highlights the significance of appropriate risk stratification and management strategies for bleeding complications associated with anticoagulants. The manuscript emphasizes the need for adaptable management strategies in regions like Latin America, where resource limitations may impact the availability of specific reversal agents.
