BAsel Stent Kosten Effektivitäts Trial - SAphenous Venous Graft Angioplasty Using Glycoprotein IIb/IIIa Receptor Inhibitors and Drug-Eluting Stents
Prospective multicenter controlled randomized trial to compare the safety and efficacy of drug eluting vs. bare metal stents in percutaneous coronary interventions of saphenous vein grafts. Hypothesis: Survival and outcome will be significantly better in patients receiving DES than in patients receiving BMS regarding both short-term and long-term outcome.
Research Question: What is the effect of the paclitaxel eluting TAXUS® Liberté® stent compared with the bare-metal Liberté® stent (both Boston Scientific Corporation, Natick, MA) in saphenous vein graft (SVG) percutaneous coronary interventions (PCI) when used in conjunction with a glycoprotein IIb/IIIa inhibitor, e.g., abciximab (ReoPro®, Eli Lilly & Co., Indianapolis, IN), and a distal filter system? Design: Prospective, multicenter, controlled randomized trial. Subjects: Inclusion criteria: Patients undergoing SVG PCI with a target vessel reference diameter ≤ 5.5 mm (visual estimate); documented silent ischemia, stable angina pectoris Canadian Cardiovascular Society (CCS) class I to IV, or acute coronary syndrome. Exclusion criteria: Previous stent implantation anywhere in the target SVG; concomitant native vessel PCI; SVG age <6 months; arterial grafts; oral anticoagulation; platelet count <100x109/L or >700x109/L; any major non-cardiac condition with a life expectancy <12 months; known allergies against the components tested; white blood cell count <3000 cell/mm3; enrolled in other study; no consent; patients unlikely to comply to the study treatment and the follow-up visits. Recruitment: Consecutive sample of all patients who qualify Variables: Predictor: Randomization will be single-blinded 1:1 to the TAXUS® Liberté® vs. the Liberté® stent (both Boston Scientific Corporation, Natick, MA). In all patients, a distal filter system will be used during PCI. The use of a glycoprotein IIb/IIIa inhibitor, e.g., abciximab (ReoPro®, Eli Lilly & Co., Indianapolis, IN), will be strongly recommended (bolus prior to PCI and 12 h infusion post PCI). Outcome: Primary: MACE after 12 months. MACE will be defined as the composite of cardiac death (all deaths not clearly non-cardiac), non-fatal myocardial infarction, and TVR. Secondary: Non-fatal myocardial infarction and cardiac death at 30 days and 6, 12, 36, and 60 months; MACE at 30 days and 6, 36, and 60 months; quality of life; individual components of the primary endpoint; non-cardiac death; major bleeding, defined as need for surgery, need for blood transfusions, and cerebral hemorrhage during antiplatelet therapy; minor bleeding, defined as a drop in hematocrit of >2 mg/dL.
