CYP2C19 and ischemic stroke: In this study, our objective was to evaluate the expression of selected platelet miRNAs (miR-126-3p, miR-19a-3p, miR-19b-3p, miR-22-3p, miR-185-5p) in patients with ischemic stroke who receive clopidogrel according to their genotypic status of CYP2C19 (*1/*1, *1/*2, *2/*2).
