Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is a multicenter, open label, prospective, single arm trial

Single arm group; following angiography, eligible patients with unprotected LMCA stenosis \>50% by visual estimation, which is equally treatable by the both treatment strategy (EES stenting or CABG), will be treated with EES

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The primary objective of the PRECOMBAT-2 trial is to establish the safety and effectiveness of coronary stenting with the everolimus-eluting Xience V stent (EES) compared with the historical control (PRE-COMBAT-1) of bypass surgery and sirolimus-eluting stent (SES) for the treatment of an unprotected LMCA stenosis. The primary alternative hypothesis is that the experimental starategy (coronary stenting with the everolimus-eluting stents) is not inferior to the standard strategy (CABG) or SES.

All consecutive patients with unprotected LMCA diseases at participating centers, who are treated with Xience V stent, will be evaluated for the entry into the study.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. The patient must be at least 18 years of age.
2. Significant de novo left main stenosis (\>50% by visual estimation) with or without any additional target lesions (\>70% by visual estimation)
3. Left main lesion and lesions outside LMCA (if present) potentially equally treatable with coronary stenting and CABG
4. Patients with stable (CCS class 1 to 4) or acute coronary syndromes (unstable angina pectoris Braunwald class IB, IC, IIB, IIC, IIIB, IIIC or NSTEMI) or patients with atypical chest pain or without symptoms but having documented myocardial ischemia
5. The patient or guardian agrees to the study protocol and the schedule of clinical and angiographic 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. The patient has a known hypersensitivity or contraindication to any of the following medications:

* Heparin
* Aspirin
* Both Clopidogrel and TIclopidine
* Everolimus, paclitaxel, ABT 578
* Stainless steel and/or
* Contrast media (patients with documented sensitivity to contrast which can be effectively pre-medicated with steroids and diphenhydramine \[e.g. rash\] may be enrolled. Patients with true anaphylaxis to prior contrast media, however, should not be enrolled).
2. Systemic (intravenous) Everolimus, paclitaxel or ABT-578 use within 12 months.
3. Any previous PCI within 1 year
4. Previous bypass surgery
5. Any previous PCI of a LMCA or ostial left circumflex artery or ostial left anterior descending artery lesion within 1 year
6. Intention to treat more than one totally occluded major epicardial vessel
7. Acute MI patients within 1 week
8. Patients with EF\<30%.
9. Patients with cardiogenic shock
10. Any disabled stroke with neurological deficit or any cerebrovascular accident within 6 months
11. Creatinine level 2.0mg/dL or dependence on dialysis.
12. Severe hepatic dysfunction (AST and ALT 3 times upper normal reference values).
13. Gastrointestinal or genitourinary bleeding within the prior 3 months, or major surgery within 2 months.
14. History of bleeding diathesis or known coagulopathy (including heparin-induced thrombocytopenia), or will refuse blood transfusions.
15. Current known current platelet count \<100,000 cells/mm3 or Hgb \<10 g/dL.
16. An elective surgical procedure is planned that would necessitate interruption of thienopyridines during the first 1 year post enrollment.
17. 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).
18. Patients who are actively participating in another drug or device investigational study, which have not completed the primary endpoint follow-up period.
19. Subject unable or unwilling to follow-up with visits required by protocol
20. Female of childbearing potential, unless a recent pregnancy test is negative, who possibly plan to become pregnant any time after enrollment into this study
