Clinical outcomes in patients with acute coronary syndromes randomized in the Acute Catheterization and Urgent Intervention Triage Strategy (ACUITY) trial who underwent percutaneous coronary intervention (PCI) of saphenous vein grafts (SVGs) were examined. The ACUITY trial assessed the safety and efficacy of bivalirudin alone versus bivalirudin plus a glycoprotein (GP) IIb/IIIa inhibitor versus heparin plus a GP IIb/IIIa inhibitor in 13,819 patients with moderate- and high-risk acute coronary syndromes, 7,789 of whom underwent PCI. A total of 329 patients (4.2%) underwent PCI of SVGs in ACUITY. ⋯ Major adverse cardiac event rates at 1 year were 37%, 37%, and 43% (p = 0.95), respectively. Minor bleeding unrelated to coronary artery bypass grafting at 30 days was significantly lower with bivalirudin alone compared with heparin plus a GP IIb/IIIa inhibitor (26% vs 38%, p = 0.05). In conclusion, bivalirudin is an effective anticoagulant in PCI of SVGs in acute coronary syndromes, with similar rates of major adverse cardiac events and net adverse cardiac events and lower minor bleeding complications in comparison with heparin plus a GP IIb/IIIa inhibitor or bivalirudin plus a GP IIb/IIIa inhibitor.
