Inclusion Criteria

Subjects must satisfy the following criteria to be enrolled in the study:
-Men or women aged =18 years
- Non valvular atrial fibrillation documented by ECG on at least 2 occasions. One occasion must be between 1 to 6 months before the screening visit and the second within 14 days before randomization
- History of prior ischemic stroke, TIA or non-CNS systemic embolism believed to be cardioembolic in origin or has 2 or more of the following risk factors:
- Heart failure and/or left ventricular ejection fraction = 35%
- Hypertension (defined as use of antihypertensive medications within
6 months before the screening visit or persistent systolic blood pressure
above 140 mmHg or diastolic blood pressure above 90 mmHg)
- Age =75 years
- Diabetes mellitus (defined as a history of type 1 or type 2 diabetes
mellitus or use of antidiabetic medications within 6 months before
screening visit)
- Female subjects must be postmenopausal (for at least 2 years), surgically sterile, abstinent, or, if sexually active, be practicing an effective method of birth control (e.g., prescription oral contraceptives, contraceptive injections, intrauterine device, double-barrier method, contraceptive patch, male partner sterilization) before entry and throughout the study; and, for those of childbearing potential, have a negative serum ß-hCG pregnancy test at screening.
- Subjects must have signed an informed consent document
- In order to participate in the optional pharmacogenomic component, subjects must have signed the informed consent for DNA research document indicating willingness to participate in the pharmacogenomic component of the study (where local regulations permit)

- Concomitant treatment with an oral or intravenous antiplatelet agent or use within 5 days before randomization (except aspirin and thienopyridines as outlined in the protocol) or concomitant treatment with a fibrinolytic agent or use within 10 days of randomization
- Anticipated need for chronic treatment with a non steroidal anti inflammatory drug
- Treatment with a strong inhibitor of cytochrome P450 3A4, such as ketoconazole or protease inhibitors, within 4 days before randomization, or planned treatment during the time period of the study
- Anemia (hemoglobin <10 g/dL) at the screening visit
- Pregnancy or breast feeding
- Any other contraindication to warfarin
