VEGFA and coronary artery disorder: In another clinical trial (Fei et al., 2018), patients with coronary artery disease (CAD) were divided into good coronary collateral circulation (CCC) formation group and poor CCC formation group, and the level of miR-503 in the plasma from good CCC or poor CCC group was lower compared with that from control subjects, and miR-503 was negatively correlated with CCC formation and VEGFA (Fei et al., 2018).
