Title: Evaluation of the Long-term Safety After Zotarolimus-Eluting Stent, Sirolimus-Eluting Stent, or PacliTaxel-Eluting Stent Implantation for Coronary Lesions - Late Coronary Arterial Thrombotic Events
Brief Summary: The purpose of ZEST-LATE (Evaluation of the Long-term Safety After Zotarolimus-Eluting Stent, Sirolimus-Eluting Stent, or PacliTaxel-Eluting Stent Implantation for Coronary Lesions - Late Coronary Arterial Thrombotic Events) trial is to assess the relationship between long-term clopidogrel use beyond 1 year and long-term rates of death or MI after DES implantation and to estimate the duration of dual antiplatelet therapy for preventing the late thrombotic events.


Options:
A: Inclusion Criteria:

1. Among the participants in the ZEST trial, event-free patients who survived the first 12 months without nonfatal MI or repeat revascularization
2. The patient or guardian agrees to the study protocol and the schedule of clinical follow-up, and provides informed, written consent, as approved by the appropriate Institutional Review Board/Ethical Committee of the respective clinical site.

Exclusion Criteria:

1. Contraindication to antiplatelet therapy
2. Non-cardiac co-morbid conditions are present with life expectancy \<1 year or that may result in protocol non-compliance (per site investigator's medical judgment).
3. Patients who are actively participating in another drug or device investigational study, which have not completed the primary endpoint follow-up period.
4. Bleeding diathesis
5. Recent stroke within 6-months
6. Concurrent organ damage (creatinine level \> 2.0mg/dL or AST and ALT \> 3 times upper normal reference values)
7. Patients with left main stem stenosis (\>50% by visual estimate)
B: Inclusion Criteria:

* Patients with TIA or minor acute ischemic stroke (NIHSS \< 4 at the time of randomization) who must NOT be candidates for acute thrombolysis or other acute intervention indicated as the current standard of care
* Aged 40 years or older
* Patients with: (a) weakness at time of TIA/minor stroke and/or language disturbance at time of TIA/minor stroke and; (b) duration of neurological deficit (TIA) \> 5 minutes
* Patients can be randomized within 24 hours of symptom onset. Symptom onset is defined by the "last seen well" principle
* Patients must have provided written, informed consent to participate in the FASTER trial.

Exclusion Criteria:

* Patients with pure sensory symptoms, pure vertigo or dizziness, pure ataxia or pure visual loss
* Patients for whom thrombolysis or other acute intervention is indicated as the current standard of care
* Patients who are currently on statin therapy, antiplatelet therapy (not including aspirin), or long-term non-steroidal anti-inflammatory drugs (NSAIDs but not COX inhibitors), or anticoagulation
* Patients who in the opinion of the site Investigator, should be commenced on statin therapy
* Patients with neurological deficit due to intracranial hemorrhage (intracranial hemorrhage, subarachnoid hemorrhage, subdural hematoma, epidural hematoma), tumor, infection or any finding not consistent with acute brain ischemia as the cause of presenting symptoms
* Presumed cardiac source of embolus (e.g. atrial fibrillation, prosthetic cardiac valve, known/suspected endocarditis)
* Patient with a concomitant acute coronary syndrome (acute myocardial infarction or unstable angina)
* Modified Rankin Score 3 or more (pre-morbid historical assessment)
* Patients in whom the qualifying event was due to a complication of cerebral angiography, a revascularization procedure or trauma
* Uncontrolled hypertension at baseline (systolic blood pressure \>180 mmHg or diastolic blood pressure \>110 mmHg), or malignant hypertension defined by brain plus acute organ involvement due to acute hypertension
* Women who are breast-feeding or pregnant. Women of childbearing potential must have a negative pregnancy test prior to randomization. Women of childbearing potential may still participate in the trial but must plan on not becoming pregnant during the course of the study and must practice a suitable method of birth control. If a patient becomes pregnant or begins breast-feeding during the study, both study drugs will be discontinued immediately, and the patient followed for the duration of the study
* Evidence of contraindication for use of Trial Medication: (i) serious systemic bleeding precluding antiplatelet therapy; (ii) hypersensitivity to aspirin, thienopyridine drugs (clopidogrel or ticlopidine) or statins; (iii) current or past history of renal insufficiency \[serum Creatinine \>150 umol\]; (iv) hepatic dysfunction indicated by any or all of the following \[ALT \>3xULN, AST \>3xULN, ALP \>3xULN\]; (v) thrombocytopenia \[platelet count \< 150 x10\^9/L\]; (vi) neutropenia \[neutrophil count \< 0.5 x10\^9/L\]; (vii) bleeding diathesis or coagulopathy indicated by any or all of the following \[INR \>1.2, PT \>1.2xULN, PTT \>1.2xULN\]
* Life expectancy of less than 90 days
* Participation in another clinical therapeutic trial (drug or device) either concurrently or within the previous 30 days, or prior participation in FASTER
* Geographical or other factors that render follow-up impractical or that render evaluation of outcome events impossible (e.g. severe dementia). Patients may be randomized who could and are willing to complete their follow-up at a participating centre
C: Inclusion Criteria:

* Korean men and women aged 20 to 85 years with coronary heart disease (CHD) or CHD equivalent patients
* Atherosclerotic plaques in coronary computed tomography (CT) or angiography or
* History of PCI or coronary artery bypass graft surgery (CABG) \> one year or
* Diabetes mellitus (including type I and type II) or
* Confirmed carotid atherosclerotic plaque with sonography, CT or angiography or
* History of peripheral artery disease or
* History of cerebrovascular disease

Exclusion Criteria:

* Patients who had history of PCI within one year
* Patients who used concomitant anticoagulants
* Patients who had hypersensitivity to aspirin or clopidogrel, serious bleeding tendency, history of intracranial hemorrhage, sign of active bleeding, uncontrolled hypertension
* Chronic alcoholism or drug addiction
* Women who were pregnant or breastfeeding or who were not using an effective method of contraception
* The use of glycoprotein IIb/IIIa inhibitor, daily NSAIDs, lipid lowering agent (except atorvastatin), or substances with possible interactions with the study drug
D: Inclusion Criteria:

* Patients undergoing primary multi-vessel CABG with at least two saphenous vein grafts, with or without the use of cardiopulmonary bypass.

Exclusion Criteria:

* Emergency surgery
* Valve surgery
* Redo CABG
* Left ventricle ejection fraction \< 25%
* Serum creatinine \> 130 µmol/L
* Preoperative use of clopidogrel (with the exception of the current admission)
* Preoperative use of warfarin; allergy to aspirin or clopidogrel.
* History of cerebrovascular accident
