BackgroundThe association between serum adiponectin levels and coronary atherosclerosis plaque characteristics in asymptomatic populations is unclear.ObjectivesTo examine the predictive value of serum adiponectin levels for coronary high risk plaques as detected by computed tomography angiography (CTA).MethodsThis was a cross-sectional study. All patients were divided into high risk plaque group and non high risk plaque group. The FRS was calculated for each patient. CTA was performed for each patient. Adiponectin levels were measured by flow fluorescence immunmicrobead assay (FFIA). Receiver-operating characteristic (ROC) curves and multivariate analysis was used to determine the predictive value of adiponectin for high risk plaques.ResultsThe high risk plaque group showed lower adiponectin levels than non high risk plaque group (median, 7.27 vs. 8.51 μg/ml, P = 0.003). The multivariate analysis showed that age (OR = 2.62, 95%CI: 1.51–4.56, P = 0.001), hyperlipidemia (OR = 1.89, 95%CI: 1.07–3.36, P = 0.029), high-density lipoprotein cholesterol (HDL-C) (OR = 0.46, 95%CI: 0.24–0.87, P = 0.02), the ratio of total cholesterol to high-density lipoproteincholesterol (TC/HDL-C) (OR = 0.69, 95%CI: 0.50–0.94, P = 0.02), apolipoprotein B (apoB) (OR = 3.08, 95%CI: 1.50–6.32, P = 0.002), and adiponectin (OR = 0.37, 95%CI: 0.19–0.74, P = 0.005) were independently associated with the presence of high risk plaques. AUC of the multivariate model for high-risk plaques was 0.728 (95%CI: 0.627–0.783). Sensitivity was 74.9%, specificity was 60.2%, the positive predictive value was 65.3%, and the negative predictive value was 70.6%.ConclusionsDecreased adiponectin levels were associated with the presence of high-risk plaques in asymptomatic populations at low to intermediate FRS. Adiponectin can play an important role in plaque screening before coronary CTA.
