Abstract
Most patients with atrial fibrillation need anticoagulant treatment with vitamin K antagonists for prevention of thromboembolism, in particular ischemic stroke. Many studies show the efficacy of this treatment but also that it is difficult to keep patients who use vitamin K antagonists in the proper treatment range. Both a too low and a too high intensity of anticoagulation significantly increase the risk of adverse events. Hence repeated monitoring of the intensity of anticoagulation and dose adjustments are required. Management strategies that improve the time in the therapeutic target range are computer-assisted dosing algorithms and centralized care in anticoagulation clinics. In addition, self-testing of the international normalized ratio and self-dosing of vitamin K antagonists has been introduced over the past 20 years and has been shown to be an effective and safe treatment modality
