Abstrakt:	Direct oral anticoagulants (DOACs), such as apixaban, are used for the prevention and management of thromboembolic diseases. Here, we present a case of a 72-year-old African American woman who presented to the hospital with shortness of breath and precordial chest pain for three days. The patient was diagnosed with volume overload associated with the progression of chronic kidney disease (CKD) and subsequently admitted to the hospital. Since the patient failed to adequately respond to diuretics, hemodialysis was initiated. During the hospital stay, she developed paroxysmal atrial fibrillation. Along with amiodarone, apixaban was started for primary stroke prophylaxis. Within 72 hours, the patient developed worsening chest pain. An echocardiogram revealed a large pericardial effusion with cardiac tamponade. She was taken for an emergent open pericardial window placement to relieve cardiac tamponade, where 600 mL of blood was drained. Considering the timeline of the development of a large bloody pericardial effusion following initiation of apixaban, spontaneous hemorrhagic cardiac tamponade attributed to the use of apixaban was diagnosed. The patient was eventually taken off all anticoagulants. In considering potential mechanisms, impaired hepatic and renal metabolism of apixaban could be factored in this case. In addition, CKD can increase bleeding risk, due to platelet dysfunction and impaired interaction of von Willebrand factor with GPIIb-IIIa. Moreover, renal secretion of apixaban is mediated by p-glycoprotein and amiodarone is an inhibitor of this protein. Although extremely rare, spontaneous hemorrhagic cardiac tamponade can occur with the use of DOACs, such as apixaban. Prompt recognition and urgent treatment remain keys to avoiding adverse patient outcomes. Competing Interests: The authors have declared that no competing interests exist.
