Research Abstract

We demonstrated that patients with coronary artery disease had low levels of adiponectin. Low adiponectin levels were associated with poor prognosis in men, while a reduction in adiponectin concentration during hospitalization correlated with future cardiac events in women with acute myocardial infarction. Statin-use and necrotic core volume highly suggestive of coronary plaque vulnerability were closely associated with adiponectin levels. The flow pattern of ophthalmic artery representative of micro vessels was involved in the severity of coronary artery disease. Our studies clarified that adiponectin had an impact on macro- and micro-vascular injury and the increase of adiponectin levels may inhibit systemic atherosclerotic change.
