ABSTRACT
Plaque disruption, platelet activation, and intracoronary artery thrombus formation
are the key events in the pathogenesis of acute coronary syndromes. Antiplatelet therapies
significantly reduce the risk of ischemic complications both during the acute phase
and in the long term in patients with acute coronary syndromes. Aspirin remains the
cornerstone of antiplatelet therapy, but there is incremental benefit when clopidogrel
or ticlopidine is added to aspirin. Dual antiplatelet therapy with the combination
of clopidogrel and aspirin is becoming the new standard of care for the management
of patients with non-ST-segment elevation acute coronary syndrome and undergoing percutaneous
coronary intervention and is currently being further evaluated in ST-segment elevation
acute coronary syndrome.
