[Rivaroxaban in prevention of stroke in patients with atrial fibrillation].

Abstract

Atrial fibrillation (AF) is well established risk factor for cardioembolic stroke. With thromboprophylatic treatment we can reduce the risk of stroke in patients with AF. Oral vitamin K antagonists (VKA) such as warfarin and acenocoumarol are effective for stroke prevention in patients with atrial fibrillation. VKAs are associated with several limitations including very narrow therapeutic range, several factors (diet, drugs, alcohol consumption) affecting the effect of VKA and excessive bleeding may occur if INR value not controlled successfully. New oral anticoagulant direct Xa factor inhibitor rivaroxaban has a good therapeutic efficacy in prevention (primary and secondary) of stroke in AF patients. Its advantages are including no need for monitoring, fixed oral dose, not affected by meal, age and body weight, all of them can improve patient adherence. In ROCKET AF trial in patients with AF, rivaroxaban was noninferior to warfarin for the prevention of stroke or systemic embolism. There was no significant between-group difference in the risk of major bleeding, although intracranial and fatal bleeding occurred less frequently in the rivaroxaban group.
