Abstract

|
|
A 76-year-old woman presented to our hospital with right-side motor weakness. She was diagnosed with paroxysmal atrial fibrillation in June 2010 and underwent treatment with warfarin and a class Ic anti-arrhythmic drug (flecainide). However, during the follow-up period, her international normalized ratio could not be controlled despite laborious adjustment of warfarin dose. Therefore, warfarin treatment was discontinued and dual antiplatelet agent therapy was initiated. Three months after stopping warfarin treatment, she presented to an emergency clinic with right-side motor weakness and was diagnosed with acute middle cerebral artery occlusion. However, as she did not wish to take warfarin, the author prescribed treatment with a new oral anti-coagulant (NOAC) in order to prevent the development of further stroke.
