Abstract

While percutaneous transluminal coronary intervention has revolutionized the management of patients with coronary artery disease, this technological advance is neither innocuous nor a panacea. In addition to the technical limitations of the procedure, it is now well recognized that serious vascular injury is caused by the treatment device that creates a perfect milieu for coronary thrombosis (1–3). Clinical trials of the monoclonal antibody abciximab (c7E3 Fab; ReoProTM, Eli Lilly and Company [Indianapolis, IN]/Centocor [Malvern, PA]) directed at the platelet glycoprotein (GP) lib/Illa integrin have clearly documented that inhibition of this receptor during coronary intervention reduces thrombotic complications and improves clinical outcomes (4–8). These positive clinical trial results, coupled with a clearer understanding of platelet physiology, have stimulated the search and encouraged the development of other parenteral inhibitors of the GP IIb/IIIa receptor.
