EDUCATE: The MEDTRONIC Endeavor Drug Eluting Stenting: Understanding Care, Antiplatelet Agents and Thrombotic Events

To provide clinical information on rates of late and very late stent thrombosis after Endeavor Drug-eluting Stent (DES)placement in an all comers population with a broad range of bleeding and thrombosis risk. EDUCATE will further analyze the current practice of clinicians regarding temporary cessation of antiplatelet therapy and its association with clinical outcomes. In addition, patients included in this broad Endeavor registry will also be contributed to the DAPT native study population for analysis of 12 vs 30 months duration of dual antiplatelet therapy.
