The T2238C variant of the ANP gene is associated with higher risk of major cardiovascular events. The purpose of this study is to investigate if this polymorphism influences the response to antiplatelet agents and it is responsible of increased platelet reactivity, thus contributing to the adverse outcome. In patients undergoing elective percutaneous coronary intervention (PCI), loaded with antiplatelets, blood samples were withdrawn for genotyping, platelet reactivity assessment and for troponin T measurement to investigate the association between the polymorphism with residual platelet reactivity and with the incidence of PPMI. No significant differences in platelet reactivity nor in PPMI incidence were observed between groups. Nevertheless, higher ARU, PRU, and % PI were detected in diabetic patients, with PRU significantly higher in carriers versus non-carriers. We observed increased residual platelet reactivity exclusively in diabetic carriers of the T2238C variant undergoing elective PCI, suggesting the need of a more effective platelet inhibition in this category of patients.
