Chronic Anticoagulation With a Reduced Dose Regimen of Rivaroxaban in End-stage Renal Disease Patients

Atrial fibrillation is the most frequent cardiac rhythm disorder and its prognosis is essentially marked by the risk of embolic events. Its treatment is based on long-term oral anticoagulant therapy according to the risk of embolic events assessed by risk scores such as the CHA2DS2-Vasc score, but this prescription is associated with a risk of hemorrhagic events that must be taken into consideration when deciding on the treatment for a given patient. There are two categories of validated oral anticoagulant treatments for the prevention of embolic events in atrial fibrillation: antivitamin K agents, which have long been the reference treatment but are restrictive and difficult to use because of a narrow therapeutic window, and direct oral anticoagulants, which are now the first-line treatment but have not been evaluated in phase II and III studies in patients with severe renal failure. End-stage renal disease (clearance \<15 mL/min/1.73m2), particularly at the dialysis stage, is a risk factor for cardiovascular disease in its own right, and a significant number of patients develop atrial fibrillation. Given the co-morbidities associated with renal failure, in particular hypertension, patients with renal failure undergoing dialysis and suffering from atrial fibrillation are generally at a higher risk of embolism than patients without renal failure, but also at a higher risk of bleeding. Thus, if the indication for prescribing oral anticoagulant therapy is clear in this populati…
