Examine the molecular role of the platelet P2Y12 receptor in thrombus stabilization and evaluate the therapeutic efficacy of P2Y12 receptor antagonists alone and in combination regimens.
Reviewed molecular and signaling studies using pathway inhibitors and genetically engineered P2Y12-null mouse models.
Evaluated clinical findings from human patients with defective ADP-mediated aggregation alongside trials of approved P2Y12 antagonists including ticlopidine and clopidogrel.
Assessed ex vivo data on combination therapies pairing P2Y12 antagonists with direct thrombin inhibitors, factor Xa inhibitors, and GPIIb-IIIa inhibitors.
P2Y12 activation by released ADP serves as a critical positive feedback mediator required for sustained platelet aggregation, thrombus stability, and adhesion to collagen and von Willebrand factor.
Targeted P2Y12 antagonism synergizes with anticoagulants, including factor Xa and thrombin inhibitors, to suppress thrombus formation ex vivo.
Combination antithrombotic regimens incorporating P2Y12 inhibitors present a clinically viable strategy to enhance protection against cardiovascular events, particularly in aspirin-resistant patients.

Implication

May guide dual therapy in aspirin-resistant patients; leaves open need for RCTs to confirm synergy with anticoagulants.
