Title: Long-Term Follow-up of Antithrombotic Management Patterns in Acute Coronary Syndrome Patients in Asia
Brief Summary: The purpose of this study is to describe the short-and long-tern (i.e. up to 2 years following the index event) AMPs in patients hospitalized for an acute coronary syndrome (i.e. STEMI or NSTE-ACS), and to document clinical outcomes, economic aspects and impact on quality of life of these AMPs in a 'real-life' setting.


Options:
A: Inclusion Criteria:

* Have symptoms suggestive of ACS that lasted at least 10 minutes at rest occurring within 7 days of randomization
* Have a diagnosis of ST-elevation myocardial infarction or non-ST elevation myocardial infarction/unstable angina (ie, chest pain or discomfort) (ST elevation is an abnormal finding from an ECG test) with at least 1 protocol-defined high risk feature

Exclusion Criteria:

* Active bleeding or high risk of bleeding or intracranial hemorrhage (bleeding within the skull enclosing the brain)
* Need for continued anticoagulant therapy
* Significantly impaired renal (kidney) or hepatic (liver) function
* Severe concomitant diseases such as cardiogenic shock (heart damage that results in insufficient blood supply to other parts or organs of the body), refractory ventricular arrhythmias (irregular contractions of the heart unresponsive to treatment), or any severe condition that would limit life expectancy of the patient to less than 6 months
B: Inclusion Criteria:

* Written informed consent has been provided.
* Diagnosis of STEMI, NSTEMI or UA
* Hospitalization for the first time within 48 hours of onset of symptoms.

Exclusion Criteria:

* UA, STEMI, NSTEMI precipitated by or as a complication of surgery, trauma, or GI bleeding or post-PCI UA, STEMI and NSTEMI occurring in patients already hospitalized for other reasons.
* Current participation in a randomised interventional clinical trial.
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:

1. Male and female patients aged 18 years or over.
2. Patients diagnosed with ACS and free of exclusion criteria below.
3. The patient is willing and able to understand the Patient Information Sheet and provide written informed consent.
4. The patient must agree to comply with the drawing of blood samples for the assessments.

Exclusion Criteria:

1. The patient has, in the opinion of the investigator, significant neurological, hepatic, renal, endocrine, cardiovascular, gastrointestinal, pulmonary, haemorrhagic, metabolic or other disease likely to confound the study requirements or analyses.
2. The patient has a history of substance abuse or demonstrates signs or clinical features of active substance abuse or psychiatric disease.
3. Alcohol consumption above recommended safe levels (i.e. more than 21 units per week for males, or more than 14 units per week for females) due to the potential effects of high alcohol levels on platelet reactivity.
4. Any illness deemed significant by the investigator during the four (4) weeks preceding the screening period of the study.
5. Any major bleeding diathesis or blood dyscrasia (platelets \< 70 x 109/l, Hb \< 8 g/dl, INR \> 1.4, APTT \> x 2 UNL, leucocyte count \< 3.5 x 109/l, neutrophil count \< 1 x 109/l).
6. Currently enrolled in an investigational device or drug trial.
