title: [Plasma level of adiponectin in coronary heart disease patients combined with abnormal glucose metabolism].
abstract: OBJECTIVE
  To examine the plasma adiponectin concentration in coronary heart disease (CHD) patients combined with abnormal glucose metabolism, and to explore the clinical significance of adiponectin.
  
  
  METHODS
  Eighty-seven hospitalized CHD patients confirmed by coronary angiography from August 2009 to April 2010 at Xiangya Hospital were enrolled and divided into 3 groups according to their glucose metabolic state: 31 patients were selected as a simple CHD group, 28 were selected as a CHD combined with impaired glucose tolerance group (CHD+IGT group), and the other 28 as a CHD combined with diabetes mellitus group (CHD+DM group). The 31 healthy subjects who got health checkup at the same time were enrolled as a normal control group (NC group). Plasma adiponectin was measured by enzyme linked immunosorbent assay. The height, weight,waistline and blood pressure of all the subjects were checked, and the fasting blood glucose (FBG), insulin, lipids, high-sensitivity C-reactive protein (hs-CRP), free fatty acids (FFA), the liver function and the renal function were checked as well. The body mass index and the homeostasis model were assessed for insulin resistance.
  
  
  RESULTS
  1) Plasma adiponectin in the CHD group, the CHD+IGT group, and the CHD+DM group was all lower than that in the NC group (P<0.05); 2) Compared with the CHD group, the plasma adiponectin in the CHD+DM group was the lowest, followed by the CHD+IGT group, and there was significant difference in the 3 groups (P<0.05); 3) Plasma adiponectin level was positively related with the high density lipoprotein cholesterol-C (HDL-C) (r=0.483, P<0.01), while it was negatively related with the hs-CRP and Gensini score (r=-0.489, P<0.05;r=-0.252, P<0.05).
  
  
  CONCLUSIONS
  Plasma adiponectin concentration is reduced in the CHD patients, and significantly reduced in CHD patients combined with abnormal glucose metabolism. Plasma adiponectin concentration decreases significantly with the severity of abnormal glucose metabolism. CHD and the abnormal glucose metabolism are important influence factors for plasma adiponectin. That plasma adiponectin level significantly decreases may be the superimposed results of CHD and abnormal glucose metabolism. Plasma adiponectin combined with HDL-C, hs-CRP and Gensini score may provide the reference in the judgement of the severity of CHD patients with abnormal glucose metabolism.
