Brief Summary

Background Drug-eluting stents (DES) have been extremely successful in reducing restenosis and the need for repeat revascularization procedures in patients who undergo PCI. The potential increased incidence of late stent thrombosis prompted cardiologists to prolong the use of dual anti-platelet therapy after the one year duration recommended by the recent ESC guidelines. However, while the premise that the cardiologists should put all their patients on dual clopidogrel-aspirin regimen for life sounds the easy way, it is an unrealistic goal because of the potential increase of bleeding complications and of the healthcare cost increase. The recent possibility to monitor aspirin with bedside assays offers a real opportunity to compare in good aspirin responder patients the two strategies: aspirin-clopidogrel regimen versus mono-aspirin regimen and to respond to the key question: can the investigators switch from dual to single antiplatelet therapy after six months in good aspirin responder patients ? Study National, multicenter, randomised prospective open group comparison of dual clopidogrel-ASA versus single ASA regimen after six months, in good ASA responder patients treated with DES (name: XIENCE) implantation. End point Primary: At 12 months: death, myocardial infarction, repeat urgent revascularization, stroke requiring a new hospitalisation and major bleedings. Secondary: Incidence at 24 and 36 months after drug eluting stent(name: XIENCE) implantation, of the same composite endpoint and incidence at 12, 24 and 36 months of minor bleeding complications Participating centres: 60 french centers Date of study beginning: November 2008 Duration of inclusion: 9 months Duration of study: 45 months

Patients after drug eluting stent implantation

You may qualify if:

  • Male or female subject ≥ 18 years of age eligible for PCI with at least one drug eluting stent (name: Xience) implanted in all clinical situations excluding primary PCI for acute MI and treatment of the left main artery.
  • Male or female subject ≥ 18 years of age eligible for PCI with at least one DES Xience.
  • Patient not pre-treated with protein IIb/IIIa inhibitors (name: abxicimab or eptifibatide) during hospitalization
  • Patient pre-treated with aspirin and clopidogrel before PCI
  • ASA check at least 24 hours after the interruption of tirofiban
  • The subject has given written informed and dated consent to participate in this study.

You may not qualify if:

  • Subjects not able to give informed consent
  • Prior implantation of DES
  • Known platelets \< 100 000/µl or known hemorrhagic diathesis
  • Oral anticoagulation or treatment with abxicimab or eptifibatide during hospitalization
  • ASA check less than 24 hours after the interruption of tirofiban
  • Thrombolytic therapy within 4 days before ASA check
  • Contra-indication to aspirin or clopidogrel
  • Recent major surgery \< 6 weeks
  • Evidence of an active gastrointestinal or urogenital bleeding
  • Severe liver insufficiency
  • Primary PCI for acute MI
  • Left main PCI
  • Any scheduled surgery during the year after enrollment
  • Severe concomitant disease with life expectation \< two years
