Arms Assigned Interventions
Conventional Strategy
Patient receive 325 mg ASA orally and loading does of 600mg Clopidogrel at time of procedure
Drug: Antiplatelet Therapy (ASA, Clopidogrel)
Standard antiplatelet PCI treatment
Other Names:
  • Thienopyridines
  • Ticlopidine
  • Clopidogrel
  • Prasugrel
Active Comparator: Aggressive Strategy
Patient receive 325mg ASA orally and loading does of 600mg Clopidogrel at time of procedure with addition of IV GP IIb/IIIa inhibitor bolus intra procedurally
Drug: Intravenous Glycoprotein inhibitor + ASA, Clopidogrel
IV Glycoprotein IIb/IIIa inhibitor bolus intra procedurally
Other Names:
  • Cangrelor
  • Abciximab
  • Eptifibatide
  • Tirofiban

Detailed Description:

This is the first US based randomized double blinded prospective study using triple antiplatelet therapy and double dose plavix maintenance dose in aspirin resistant patients undergoing elective PCI through femoral access. The primary outcome of this study is an elevation of cardiac enzymes within 24 hours after the PCI with a secondary outcome of a composite of major adverse cardiac events of death, MI, stent thrombosis and urgent revascularization and bleeding up to 30 days.
