The important clinical indicators of CAD include CRP, IL-6, lipid index (TG, TC, LDL-C, HDL-C), FMD, fibrinogen, TNF-α, etc. Therefore, systemic inflammation index (CRP, IL-6), endothelial function index (FMD), and lipid metabolism index (TG, TC, LDL-C, HDL-C) have served as outcome indicators in this study. The gene discussed is IL6; the disease is coronary artery disorder.
