Antiaggregating therapy in acute myocardial infarction.
The clinical benefit of aspirin in the acute phase of myocardial infarction is dramatically suggested by the results of the ISIS-2 trial. However, the time course of pathophysiological events that lead to such a determining involvement of platelets still appears uncertain and further study is needed to single out exactly how early and how long antiplatelet drugs should be given, since there is a risk of bleeding complications due to the combination of the different antithrombotic therapies. Thrombolytic agents and heparin are in fact widely used for patients with acute myocardial infarction, even if the optimal schedule of treatment, including anti-aggregating therapy, is not yet firmly established. To avoid rethrombosis and to enhance the efficacy of coronary thrombolysis, thus reducing early mortality, several newer antiplatelet agents other than aspirin, such as antibodies against the platelet receptor of adhesive proteins, the glycoprotein IIb/IIIa and the RGD peptides, are currently under investigation.
