We found that rs4244285 G>A polymorphism of the CYP2C19 gene was associated with the risk of HALT in the overdominant model (OR 4.00 [1.15-13.97], P = 0.02 for GA vs. GG+AA) adjusted by sex and the presence of pre-TAVR AF.
Eighty patients who were complicated with atrial fibrillation and treated with clopidogrel antiplatelet therapy after PCI in Meizhou Hospital Affiliated to Zhongshan University from September 2015 to January 2017 were selected, and divided into two groups according to the CYP2C19 genotype: extensive metabolism (EM) group and poor metabolism (PM) group.
This study aimed to determine the impact of CYP2C19 gene polymorphism on warfarin maintenance doses in patients with non-valvular atrial fibrillation for the progress in overcoming obstacles facing warfarin pharmacogenetics.
The aim of this study was to evaluate the association between CYP2C9*2, CYP2C9*3, VKORC1, CYP4F2*3, ABCB1 C3435T, APOE, CYP2C19*2 and CYP2C19*17 gene polymorphisms and treatment safety in 128 patients diagnosed with atrial fibrillation or venous thromboembolism during the initial first seven months of acenocoumarol therapy.
