Title: Randomized Evaluation of Long Term Anticoagulant Therapy (RE-LY) Comparing the Efficacy and Safety of Two Blinded Doses of Dabigatran Etexilate With Open Label Warfarin for the Prevention of Stroke and Systemic Embolism in Patients With Non-valvular Atrial Fibrillation: Prospective, Multi-centre, Parallel-group, Non-inferiority Trial (RE-LY Study)
Brief Summary: The primary objective of this trial is to demonstrate the efficacy and safety of dabigatran etexilate in patients with non-valvular atrial fibrillation for the prevention of stroke and systemic embolism.


Options:
A: Inclusion Criteria:

* Patients with Nonvalvular Atrial Fibrillation (NVAF) aged 80 years or older who are ineligible for available oral anticoagulation therapy

Exclusion Criteria:

* Patients with active bleeding
* Patients who have poorly controlled hypertension
* Patients who have liver dysfunction accompanied with disorder of blood coagulation
B: Inclusion Criteria:

* Recent ESUS (between 7 days and 6 months), defined as:
* Recent ischemic stroke (including transient ischemic attack with positive neuroimaging) visualized by brain imaging that is not lacunar, and
* Absence of cervical carotid atherosclerotic stenosis\> 50% or occlusion, and
* No atrial fibrillation after ≥ 24-hour cardiac rhythm monitoring, and
* No intra-cardiac thrombus on either transesophageal or transthoracic echocardiography, and
* No other specific cause of stroke (for example, arteritis, dissection, migraine/vasospasm, drug abuse)

Exclusion Criteria:

* Severely disabling stroke (modified Rankin score ≥4)
* Indication for chronic anticoagulation or antiplatelet therapy
* Estimated glomerular filtration rate (eGFR) \< 30 mL/min/1.73 m\^2
C: Inclusion criteria Patients with non-valvular atrial fibrillation (AF), at moderate to high risk of stroke, or systemic embolism with at least one additional risk factor (i.e. previous ischemic stroke, TIA, or systemic embolism, left ventricular dysfunction, age \>=75 years, age \>=65 with either diabetes mellitus, history of coronary artery disease or hypertension)

Exclusion criteria

1. Prosthetic heart valves requiring anticoagulation per se, or hemodynamically relevant valve disease that is expected to require surgical intervention during the course of the study
2. Severe, disabling stroke within the previous 6 months, or any stroke within the previous 14 days
3. Conditions associated with an increased risk of bleeding
4. Contraindication to warfarin treatment
5. Reversible causes of atrial fibrillation (e.g., cardiac surgery, pulmonary embolism, untreated hyperthyroidism).
6. Plan to perform a pulmonary vein ablation or surgery for cure of the AF
7. Severe renal impairment (estimated creatinine clearance \<=30 mL/min)
8. Active infective endocarditis
9. Active liver disease
10. Women who are pregnant, lactating, or of childbearing potential who refuse to use a medically acceptable form of contraception throughout the study
11. Anaemia (haemoglobin \<100g/L) or thrombocytopenia (platelet count \<100 x 109/L)
12. Patients who have developed transaminase elevations upon exposure to ximelagatran
13. Patients who have received an investigational drug in the past 30 days or are participating in another drug study
14. Patients considered unreliable by the investigator concerning the requirements for follow-up during the study and/or compliance with study drug administration, has a life expectancy less than the expected duration of the trial due to concomitant disease, or has any condition which in the opinion of the investigator, would not allow safe participation in the study (e.g., drug addiction, alcohol abuse)
15. Any known hypersensitivity to galactose if the warfarin used contains galactose.
D: Inclusion Criteria:

* Adult patients (≥ 18 years) with acute ischemic stroke and atrial fibrillation
* Eligible and willing to start (or re-start) NOAC
* Registered in The Swedish Stroke Register
* Signed informed consent

Exclusion Criteria:

* Contraindication to NOAC (e.g. ongoing bleeding, mechanical heart valve prosthesis)
* Ongoing therapy with NOAC (without ≥2 days interruption at index stroke)
* International normalized ratio (INR)\>1.7
* No second brain imaging (CT/MRI) after thrombolysis/thrombectomy
* Previous randomization in the TIMING study
