Abstract

One of the most significant advances of the last decade has been the development of platelet glycoprotein (GP) IIb/IIIa receptor inhibitors. A large series of randomised, controlled clinical trials of these agents have shown a significant reduction in ischaemic events, not only in acute coronary syndrome patients, but also in patients who undergo elective percutaneous coronary interventions. Even though the use of oral antiplatelet and antithrombotic therapies in addition to percutaneous coronary interventions have had a significant impact in clinical outcomes after acute coronary syndromes, the use of GP IIb/IIIa inhibitors provide additional protection against recurrent ischaemia and has been identified as the pivotal mediator of platelet aggregation, making it a logical target for the control of platelet response to vascular injury. A series of key trials performed over the last few years with GP IIb/IIIa inhibitors in patients undergoing percutaneous coronary intervention, have shown a reduction in the risk of short-term death and non-fatal myocardial infarction. The pharmacology and molecular basis of GP IIb/IIIa receptor inhibition and the use of these agents in patients undergoing percutaneous coronary intervention (during acute coronary syndromes and in elective procedures) and their safety issues will be reviewed. A special emphasis has been made on the role of these agents in diabetic patients and their beneficial effect in reducing peri-procedural creatine kinase myocardial band fraction elevation and associated complications.
