Abstract
ObjectiveTo investigate the relations of circulating adhesion molecule vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) with carotid artery elasticity in patients with impaired glucose regulation (IGR). MethodsA total of 208 subjects were enrolled from January 2013 to March 2014. One hundred forty-eight were IGR patients, and 60 had normal glucose tolerance (NGT). Carotid intima-media thickness (IMT), carotid artery pressure-strain elasticity coefficient (Eρ), stiffness (β), arterial compliance (AC), and pulse wave velocity (PWVβ), as well as blood pressure, body mass index, blood glucose, blood lipids, insulin resistance index, VCAM-1, and ICAM-1 were measured and compared between IGR and NGT patients. ResultsEρ, β and PWVβ were significantly higher in the IGR group than in the NGT group (P<0.05), but the IMT showed no significant difference (P>0.05). VCAM-1 and ICAM-1 were significantly higher in the IGR group than in the NGT group (P<0.05). VCAM-1 and ICAM-1 were positively correlated with Eρ, β, and PWVβ and negatively correlated with AC in IGR patients. ConclusionsChanges in carotid artery elasticity and endothelial dysfunction are found in patients with IGR. Early comprehensive intervention should be performed in such IGR populations.
