Management of Antiplatelet Therapy During Acute Percutaneous Coronary Intervention: New Strategies and Therapeutics



Download PDF


Aggressive intravenous and oral dual antiplatelet therapy has established primary percutaneous coronary intervention (PCI) as the standard of care for acute myocardial infarction. Clopidogrel is currently the thienopyridine of choice for dual antiplatelet therapy in patients treated with PCI. The dose regime and duration of therapy of clopidogrel has undergone multiple refinements. Recently, 2 novel third generation oral inhibitors of P2Y12 receptors, prasugrel and ticagrelor, have undergone clinical evaluation with promising results. This article is a non-exhaustive review of the literature, concentrating on the role of current and novel oral antiplatelet agents for acute myocardial infarction particularly highlighting the limitations and issues associated with clopidogrel use.

Platelet adhesion, activation, and aggregation are stimulated during an acute coronary syndrome (ACS), the result of intimal injury due to rupture of an atherosclerotic plaque. This triggers a cascade of events leading to the catastrophic formation of an occlusive clot. Antiplatelet agents assume the cornerstone role in modern pharmacotherapy for ablating this process in the management of ACS.
