Correlation between Serum Level of Adiponectin and Severity of Coronary Artery Atherosclerosis

Objectives To investigate the correlation between serum level of adiponectin and severity of coronary artery atherosclerosis. Methods Coronary angiographies were performed and serum levels of adiponectin were measured in 88 patients with suspected coronary heart disease （CHD）. Patients were divided into groups according to the coronary angiographies and Gensini＇s scores of coronary artery atherosclerosis. The serum levels of adiponectin were compared in different groups, and multiple regressions were used to analyze the correlation factors of adiponectin. Results （1）Serum adiponectin concentration in CHD group [ 7. 1 mg/L （2.4 - 21.1 mg/L） ] was decreased as compared with that in control group [ 11.6 mg/L （4.4 - 28.2 mg/L ）, P 〈 0. 01 ] ; （2）The serum levels of adiponectin fell while the Gensini＇ s scores of coronary artery atherosclerosis increased （P 〈 0. 05, P 〈 0. 01 ） ; （3）Serum level of adiponectin was positively correlated with the high-density lipoprotein cholesterol, while negatively correlated with the Gensini＇ s score of coronary artery atherosclerosis and triglyceride （P 〈 0. 01 ）. Conclusions Serum adiponectin concentration was decreased in patients with CHD. Low serum levels of adiponectin reflected the severity of coronary artery atherosclerosis. Adiponectin was a protective factor of cardiovascular system.
