Plasma apoCIII, hs-CRP and TNF-α levels in the CHD subgroups with AMI, unstable angina, and stable angina were increased compared to those in the healthy control group (P < 0.01), with significant differences also identified between each pair of subgroups with AMI, unstable angina, and stable angina (P < 0.01) (Fig. 3). This evidence concerns the gene APOC3 and angina pectoris.
