NCT00590174

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.

Eligibility Criteria

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

You may qualify if:

  • Among the participants in the ZEST trial, event-free patients who survived the first 12 months without nonfatal MI or repeat revascularization
  • 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.

You may not qualify if:

  • Contraindication to antiplatelet therapy
  • 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).
  • Patients who are actively participating in another drug or device investigational study, which have not completed the primary endpoint follow-up period.
  • Bleeding diathesis
  • Recent stroke within 6-months
  • Concurrent organ damage (creatinine level \> 2.0mg/dL or AST and ALT \> 3 times upper normal reference values)
  • Patients with left main stem stenosis (\>50% by visual estimate)
