A Study of Apixaban in Patients With Atrial Fibrillation Not Caused by a Heart Valve Problem Who Are at Risk for Thrombosis (Blood Clots) Due to Having Had a Recent Coronary Event Such as a Heart Attack or a Procedure to Open the Vessels of the Heart

Brief description of study

The purpose of this study is to determine if Apixaban is safer than a Vitamin K Antagonist given for 6 months in terms of bleeding in patients with an irregular heart beat (atrial fibrillation) and a recent heart attack or a recent procedure to open up a blood vessel in the heart. All patients would also be taking a class of medicines called P2Y12 inhibitors (such as clopidogrel/Plavix) and be treated for up to 6 months. The primary focus will be a comparison of the bleeding risk of Apixaban, with or without aspirin, versus a Vitamin K antagonist, such as warfarin, with or without aspirin.

Detailed Study Description

Patients will be recruited from either inpatient coronary care or general medical units, or recruited from outpatient cardiology offices.
