Objective: Besides its major role in the regulation of food intake and energy expenditure, leptin is involved in the pathogenesis of obesity-associated atherosclerosis. However, the clinical association between leptin and arterial stiffness, a surrogate marker for cardiovascular disease, has not been fully elucidated. This study aimed to investigate the association between the plasma leptin level and arterial stiffness in patients with type 2 diabetes.
Methods: Three hundred eighteen patients with type 2 diabetes, of which 155 were overweight (body mass index ≥ 25 kg/m2), were included in this study. Fasting plasma leptin levels were measured by enzyme-linked immunosorbent assay. Stiffness of the common carotid artery was evaluated by ultrasonography using Peterson’s elastic modulus (Ep) and arterial compliance (AC). A.. View More»
