Matrix metalloproteinase(MMP)-22 and-29 and pro-inflammatory cytokine interleukin-18(IL18) are present in human hearts. IL18 may regulate MMP-22 and-29 expression, which may correlate with CHD progression. Methods and results: Immunoblot analysis showed that IL18 induced MMP-22 expression in human aortic smooth muscle cells. The Mann Whitney test from a prospective study of 194 CHD patients and 68 non-CHD controls demonstrated higher plasma levels of IL18, MMP-22 and-29 in CHD patients than in the controls. A logistic regression test suggested that plasma IL18(odds ratio(OR)=1.131, P=0.007), MMP-22(OR=1.213, P=0.040), and MMP-29(OR=1.198, P=0.033) were independent risk factors of CHD. Pearson's correlation test showed that IL18(coefficient(r)=0.214, P=0.045; r=0.246, P=0.031) and MMP-22(r=0.273, P=0.006; r=0.286, P=0.012) were associated with the Gensini score before and after adjusting for potential confounding factors. The multivariate Pearson's correlation test showed that plasma MMP-22 levels correlated positively with high-sensitive-C-reactive protein(hs-CRP)(r=0.167, P=0.023), and MMP-29 levels correlated negatively with triglyceride(r=-0.169, P=0.018). Spearman's correlation test indicated that plasma IL18 levels associated positively with plasma MMP-22(r=0.845, P<0.001) and MMP-29(r=0.548, P<0.001). Conclusions: Our observations suggest that IL18, MMP-22 and-29 serve as biomarkers and independent risk factors of CHD. Increased systemic IL18 in CHD patients may contribute to elevated plasma MMP-22 and-29 levels in these patients.展开更多
