Association of circulating matrix metalloproteinase-1, but not adiponectin, with advanced coronary artery disease.

Objective: Recent evidence suggests that high tissue matrix metalloproteinase-1 (MMP-1) and low adiponectin may serve as biomarkers of atherosclerosis. Results on the associations of circulating MMP-1 and adiponectin concentrations are scarce. We hypothesized that patients with multivessel coronary artery disease (CAD) have elevated high-sensitivity C-reactive protein (hs-CRP), MMP-1 but low adiponectin levels, and concomitant measurements of these biomarkers could improve predictive strength for advanced CAD.
