Primary outcomePrimary: Vein Graft Intimal Area — 4.1; 4.5 mm
Summary
The purpose of this study is to determine whether the combination of clopidogrel with aspirin prevents the development of blockages (atherosclerosis) in vein grafts one year after coronary artery bypass surgery (CABG) compared to aspirin alone.
