Plasma apoCIII, hs-CRP and TNF-α levels in the CHD subgroups with mild, moderate, and severe stenosis were enhanced compared to those in the healthy control group (P < 0.01), while there were no significant differences between each pair of subgroups with severe, moderate, and mild stenosis (P > 0.05) (Fig. 2). This evidence concerns the gene APOC3 and coronary artery disorder.
