Genetic Polymorphism Associated With Coronary Heart Disease Susceptibility and Variability of Clopidogrel Response

Brief summary (registry, in English)

The pathogenesis of CHD remains poorly known despite much research over the last few decades. Numerous non-genetic variables have been demonstrated to have a significant impact on the risk of CHD. However, the fact that many individuals with severe CHD do not have any of these non-genetic risk factors supports the notion that genetic factors play a role in the occurrence and progression of CHD. In this study, we investigated the association of polymorphisms affecting Vascular endothelial factors A (VEGFA) and its receptor VEGFR2 (rs3025039, rs699947, rs2305948, rs1870377), CXCR4 (rs2228014), CCR2 (rs1799864), C3 (rs2230199), CCL2 (rs1024611 and rs2857656) and CCL5 (rs2107538 and rs22280789) with CHD susceptibility and the severity of coronary lesion. On another side, clopidogrel is largely prescribed in association with aspirin in order to prevent atherothrombotic complications in patients with acute coronary syndrome. Its effectiveness is undeniably proven by several studies and clinical trials over the years, however, some patients have presented ischemic events such as thrombosis on stent or myocardial infarction despite a well-conducted treatment. This clopidogrel non-responsiveness is probably multifactorial; several genetic and non genetic factors may contribute to impaired platelet inhibition by clopidogrel. In this regard, it is meaningful to determine genetic polymorphisms contributing to the variability of clopidogrel response in patients with Coronary Artery Therefore, the goal of this study is to determine the impact of the polymorphisms, affecting CYP2C19, PON, ABCB1, ITGB3 and P2RY12 genes, on the response to clopidogrel in patients with CAD.Disease (CAD). In fact, the recognition of these factors might predict the exposure to the risk of thrombosis and cardiovascular death in these patients.
