Adipocyte cytokines regulate glucose metabolism and insulin resistance and adiponectin is thought to have a protective effect against atherosclerosis. Studies have shown that adiponectin expression is decreased in obese subjects and those with metabolic syndrome or diabetes mellitus. The purpose of this study was to investigate the relationship between circulating adipocyte cytokine concentrations and angiographic coronary artery disease (CAD) progression in patients with chest pain. Patients with stable angina pectoris who underwent repeat coronary angiograms and had serum samples at the time of first catheterization between March 1999 and January 2004 were enrolled. A modified Gensini scoring system was used to define angiographic coronary artery progression between the index and follow-up angiograms. Those who had significant angiographic progression of coronary lesions were classified into the progression group (N=55). Those who did not have CAD progression were classified into the non-progression group (N=102). Univariate analysis showed that CAD progression was associated with male gender (93% vs. 78%, p=0.038), higher baseline total cholesterol (187+/-43 vs. 173+/-39 mg/dl, p=0.037) and higher baseline fasting blood glucose (128+/-57 vs. 110+/-40 mg/dl, p=0.037). Patients in the progression group had a significantly lower serum adiponectin level (14.3+/-7.9 vs. 18.9+/-13.2 mug/ml, p=0.007) than, but resistin (28.9+/-13.4 vs. 34.4+/-26.0 ng/ml, p=0.142) and leptin (7.4+/-4.6 vs. 7.7+/-6.5 ng/ml, p=0.675) levels similar to, those in the non-progression group. In a multivariate binary logistic regression model, male gender (odds ratio 4.283, p=0.015), higher serum cholesterol (odds ratio 1.010, p=0.032) and lower serum adiponectin (odds ratio 0.959, p=0.030) were all significant independent predictors of CAD progression. In conclusion, we found that a decreased circulating level of adiponectin is associated with angiographic CAD progression in patients with angina pectoris.
