NCT00422968

Brief Summary

The primary objective of the PRE-COMBAT trial is: To establish the safety and effectiveness of coronary stenting with the sirolimus-eluting balloon expandable stent (Cordis Johnson \& Johnson, Warren, New Jersey) compared with bypass surgery for the treatment of an unprotected LMCA stenosis. The alternative hypothesis is that the experimental strategy (coronary stenting with the sirolimus-eluting stents) is not inferior to the standard strategy (bypass surgery).

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • The patient must be at least 18 years of age.
  • Significant de novo left main stenosis (\>50% by visual estimation) with or without any additional target lesions (\>70% by visual estimation)
  • Left main lesion and lesions outside LMCA (if present) potentially equally treatable with coronary stenting and bypass surgery
  • 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
  • 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.

You may not qualify if:

  • The patient has a known hypersensitivity or contraindication to any of the following medications:
  • Heparin
  • Aspirin
  • Both Clopidogrel and TIclopidine
  • Sirolimus, 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).
  • Systemic (intravenous) Sirolimus, paclitaxel or ABT-578 use within 12 months.
  • Any previous PCI within 1 year
  • Previous bypass surgery
  • Any previous PCI of a LMCA or ostial left circumflex artery or ostial left anterior descending artery lesion within 1 year
  • Intention to treat more than one totally occluded major epicardial vessel
  • Acute MI patients within 1 week
  • Patients with EF\<30%.
  • Patients with cardiogenic shock
  • +11 more criteria
