Title: A Phase 3, Active (Warfarin) Controlled, Randomized, Double-Blind, Parallel Arm Study to Evaluate Efficacy and Safety of Apixaban in Preventing Stroke and Systemic Embolism in Subjects With Nonvalvular Atrial Fibrillation
Brief Summary: The trial seeks to determine if apixaban, an investigational anticoagulant (blood-thinner) is as effective as standard therapy (warfarin) in preventing stroke and systemic embolism in subjects with atrial fibrillation and risk factors for stroke.


Options:
A: Inclusion criteria:

* Male or female patients aged \>=18 years
* Patients with Non Valvular Atrial Fibrillation
* Patient presenting with:

An Acute Coronary Syndrome (ACS) (ST elevation myocardial infarction (STEMI), NonSTEMI \[NSTEMI\] or unstable angina \[UA\]) that was successfully treated by PCI and stenting (either Bare Metal Stent (BMS) or Drug Eluting Stent) Or Stable Coronary Artery Disease with at least one lesion eligible for PCI that was successfully treated by elective PCI and stenting (either BMS or DES)

* The patient must be able to give informed consent in accordance with International Conference on Harmonisation Good Clinical Practice guidelines and local legislation and/or regulations.

Exclusion criteria:

* Patients with a mechanical or biological heart valve prosthesis
* Cardiogenic shock during current hospitalisation
* Stroke within 1 month prior to screening visit
* Patients who have had major surgery within the month prior to screening
* Gastrointestinal haemorrhage within one month prior to screening, unless, in the opinion of the Investigator, the cause has been permanently eliminated
* Major bleeding episode including life-threatening bleeding episode in one month prior to screening visit
* Anaemia (haemoglobin \<10g/dL) or thrombocytopenia including heparin-induced thrombocytopenia (platelet count \<100 x 109/L) at screening
* Severe renal impairment (estimated Creatinine Clearance (CrCl) calculated by Cockcroft-Gault equation) \<30mL/min at screening
* Active liver disease
B: Inclusion Criteria:

* Patients must have documented atrial fibrillation on 2 separate occasions within 6 months before screening
* History of a prior stroke, transient ischemic attack or non-neurologic systemic embolism believed to be cardiac in origin, or at least two of the following risk factors: heart failure, hypertension, age 75 years or greater, diabetes mellitus

Exclusion Criteria:

* Significant mitral stenosis
* Transient atrial fibrillation caused by a reversible disorder
* Active internal bleeding
* Severe disabling stroke
* History of intracranial bleeding
* Hemorrhagic disorders
C: Inclusion Criteria:

* Males and females ≥ 18 yrs with atrial fibrillation (AF) and one or more of the following risk factors for stroke:
* Age ≥ 75, previous stroke
* transient ischemic attack (TIA) or Systemic Embolism (SE)
* Symptomatic congestive heart failure or left ventricular dysfunction with left ventricular ejection fraction (LVEF) ≤ 40%
* Diabetes mellitus or hypertension requiring pharmacological treatment
D: Inclusion Criteria:

* A person who has been diagnosed with acute coronary syndrome and is to undergo a percutaneous coronary intervention.
* A person who is of the legal age of 18 and is mentally competent to provide a signed written informed consent.
* If a woman is of childbearing potential (i.e., before menopause), she must test negative for pregnancy and agree to use a reliable method of birth control.

Exclusion Criteria:

* A person who has had an ischemic stroke within the last 3 months or a hemorrhagic stroke at any time in the past.
* A person who has active internal bleeding or has a history of a bleeding disorder.
* Individuals who are at an increased risk of bleeding based on laboratory criteria evaluated by the treatment physician or on medication that can cause bleeding.
* A person who has liver disease; for example, cirrhosis.
* A person who has a condition such as alcoholism, mental illness, or is drug dependent.
* A person who has cardiogenic shock, a refractory ventricular arrhythmia, or congestive heart failure (class IV).
