While general treatment strategies for AF may largely be transferred to patients with mild to moderate CKD, patients with advanced CKD-particularly hemodialysis (HD) patients-with AF pose substantial therapeutical challenges to cardiologists and nephrologists. The arguably greatest dilemma is the very limited evidence on appropriate strategies for prevention of stroke and systemic embolism in HD patients with AF, since the risk for both thromboembolic events without oral anticoagulation and severe bleeding events with oral anticoagulation are substantially increased in advanced CKD, compared with the general population. Thus, the benefit to risk ratio of either vitamin K antagonists or direct oral anticoagulants is less evident in HD than in non-CKD patients with AF.
