Platelet GP IIb-IIIa Receptor Antagonists in Primary Angioplasty: Back to the Future

Abstract Coronary artery disease and acute myocardial infarction still represent the leading cause of mortality in developed countries. Therefore, great efforts have been made in the last decades to improve reperfusion strategies and adjunctive antithrombotic therapies. In fact, despite optimal epicardial recanalisation, a large proportion of patients still experience impaired reperfusion and in-stent thrombosis. The adjunctive use of glycoprotein (GP) IIb-IIIa inhibitors may certainly contribute in the reduction of such complications, especially when administered in the early phase of infarction. In fact, in this phase a larger platelet composition of the thrombus and the presence of a larger amount of viable myocardium, as compared to a delayed phase, may increase the benefits from this therapy and counterbalance the potential higher risk of bleeding. A large body of evidence has been accumulated on the benefits from GP IIb-IIIa inhibitors in terms of prevention of stent thrombosis, and benefits in mortality, especially among high-risk patients and as upstream strategy. Therefore, based on current available data, GP IIb-IIIa inhibitors can be recommended as early as possible (upstream strategy) among high-risk patients, such as those with advanced Killip class or anterior myocardial infarction (MI), and those presenting within the first three hours. Even though it is not universally accepted, in our opinion this strategy should be implemented in a pre-ho...
