Title: A Randomized, Double-Blind, Double-Dummy, Active-controlled, Parallel-group, Multicenter Study to Compare the Safety of Rivaroxaban Versus Acetylsalicylic Acid in Addition to Either Clopidogrel or Ticagrelor Therapy in Subjects With Acute Coronary Syndrome
Brief Summary: The purpose of this study is to estimate the risk of bleeding with rivaroxaban, compared with acetylsalicylic acid (ASA), in addition to a single antiplatelet/ platelet adenosine diphosphate P2Y12 receptor antagonist (P2Y12 inhibitor agent: clopidogrel or ticagrelor), in participants with a recent acute coronary syndrome (ACS: including ST segment elevation myocardial infarction \[STEMI\] and non-ST-segment elevation acute coronary syndrome \[NSTE-ACS\]).


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:

* a long-term indication for oral anticoagulation treatment (until at least 1 year after the study)
* a severe coronary lesion (at least 75% stenosis on angiography or fractional flow reserve lower than 0•80) with indication for PCI
* age 18-80 years

Exclusion Criteria:

* history of intracranial bleeding;
* cardiogenic shock;
* contra indication to use of antiplatelet or anticoagulation drugs;
* peptic ulcer in the previous 6 months;
* thrombo cytopenia (platelet concentration lower than 50\~10⁹/L);
* major bleeding (according to the Thrombolysis in Myocardial Infarction \[TIMI\] criteria) in the past 12 months; and
* pregnancy.
C: Inclusion Criteria:

* Participants, 18 years or older, must have symptoms suggestive of acute coronary syndrome (ACS) (angina, or symptoms thought to be equivalent) within 48 hours of hospital presentation, or developed ACS while being hospitalized, and has a diagnosis of: a) ST segment elevation myocardial infarction (STEMI); b) non-ST-segment elevation acute coronary syndrome (NSTE-ACS). However, participant who is 54 years of age or younger must also have either diabetes mellitus or a history of a prior myocardial infarction (MI), in addition to the presenting ACS event
* Participant must be randomized within the screening window of 10 days after hospital admission for the index ACS event. Participant should have received acute phase treatment for the index ACS, such as intravenous anticoagulant or antiplatelet, and are receiving maintenance dual antiplatelet therapy (DAPT) with either clopidogrel plus acetyl salicylic acid (ASA), or ticagrelor plus ASA, with the intent to continue the treatment with a platelet adenosine diphosphate P2Y12 receptor antagonist (P2Y12 inhibitor) after randomization
* Participants must agree to provide a pharmacogenomics deoxyribonucleic acid (DNA) sample

Exclusion Criteria:

* Participant has any conditions that, in the opinion of the investigator, contraindicates anticoagulant therapy or would have an unacceptable risk
* Participant with a prior stroke of any etiology or transient ischemic attack (TIA)
* Participant who received thrombolytic therapy as treatment for the index ACS event cannot be enrolled in the ticagrelor stratum
* Participant has anticipated need for chronic administration of omeprazole or esomeprazole concomitantly with clopidogrel
* Participant has known allergy or intolerance to ASA or rivaroxaban
D: 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
