Novel anticoagulants vs warfarin for stroke prevention in atrial fibrillation

摘要

Warfarin has remained the mainstay of stroke prevention in atrial fibrillation for the past 60 years. Recently, two new groups of novel oral anticoagulants-direct thrombin inhibitors (dabigatran) and factor Xa inhibitors (rivaroxaban, apixaban, edoxaban) have shown promising results in well conducted clinical trials in terms of efficacy, safety and convenience of usage. However, in real world practice these novel agents come with their share of side effects and drawbacks which the prescribing physician must be aware about. In this review we discuss the role of these novel agents in real world clinical practice-their advantages, disadvantages and future directions.
