Changes in proinflammatory cytokine and destructive metalloproteinase levels during formation of unstable atherosclerotic plaque

We studied men with coronary atherosclerosis without acute coronary syndrome and determined typical valuable parameters of inflammatory (tumor necrotic factor, antagonist of receptor to interleukin [IL] 1, IL 6, IL 8, monocytes chemotactic protein 1, endothelial monocytes activating protein II), and destructive (matrix metalloproteinase [MMP] 3, MMP 7, MMP 9, tissue inhibitor of metalloproteinase) processes at consecutive stages of formation of coronary atherosclerotic plaque: "normal intimal tissue --> lipid stain --> early stable plaque --> unstable vulnerable plaque <--> stable plaque with fibrosis", and in 3 types of unstable plaques (lipid type, inflammatory erosive type, necrotic type).
