We evaluated the impact of bivalirudin versus unfractionated heparin (UFH) plus glycoprotein IIb/IIIa inhibitor (GPI) on clinical outcomes in pts with STEMI undergoing primary PCI of the LAD. Methods: In the HORIZONS-AMI trial, 3,602 pts were randomized to bivalirudin monotherapy vs. heparin + GPI. Of these, 1,445 pts underwent primary PCI of the LAD, whereas 1,884 pts underwent primary PCI of only non-LAD lesions.

Introduction: Stent thrombosis (ST) is a catastrophic occurrence burdened by a high mortality rate, and with tendency to recur.
