RESUMO
Concentrations of tumor necrosis factor, interleukin 1- and its receptor antagonist, IL-6, IL-8, IL-18, IL-2, ligand of CD40 receptor (CD40L), high sensitive C-reactive protein (hsCRP), monocyte chemotactic protein -1, endothelial monocyte activating protein II, adhesive molecules (sICAM-1 and sVCAM-1), matrix metalloproteinase (MMP-3, MMP-7, MMP-9), tissue inhibitor of metalloproteinase (TIMP-1) and endothelin-1 were studied in blood and in coronary artery intima/media of men with coronary atherosclerosis without acute coronary syndrome. Blood levels of hsCRP, IL-8, IL-6 and CD40L were higher, while blood levels of sVCAM and TIMP-1 were lower in men with prevalence of unstable atherosclerotic plaques compared to men with prevalence of stable atherosclerotic plaques in coronary arteries. Blood levels of hsCRP, IL-6 and IL-8 correlated with characteristics of coronary artery atherosclerotic plaques instability. Correlation between hsCRP blood level and hsCRP concentration in coronary artery intima/media material was also revealed.
