Impact of genetic polymorphisms in the clinical response of oral inhibitors of the platelet P2Y12 adenosine diphosphate (ADP) receptor

Dual antiplatelet therapy with clopidogrel combined to aspirin reduces ischemic events in a wide range of patients with cardiovascular disease. However, a large interindividual variability has been observed in the pharmacodynamics response of clopidogrel with lower platelet inhibition associated with increased risk for major adverse cardiovascular events. Multiple mechanisms have been proposed for the variable response to clopidogrel, among which the impact of pharmacogenetic seems to play an important role.
