ABSTRACT
<p><b>OBJECTIVE</b>To investigate the relationship between insulin resistance and carotid atherosclerosis in patients with potential hyperglycemia.</p><p><b>METHODS</b>A total of 221 patients were recruited among those with potential hyperglycemia. All participants underwent physical examination, medical history interview, and 75 g oral glucose tolerance test. Venous blood was sampled for measurement of insulin and cholesterol levels. The intima-media thickness (IMT) in bilateral common carotid arteries was observed by B-mode ultrasound. Insulin resistance index was calculated by homeostasis model assessment (HOMA-IR). Subjects were stratified in quintiles according to HOMA-IR values. Risk factors and atherosclerotic parameters were analyzed.</p><p><b>RESULTS</b>With HOMA-IR value increase, incidence of impaired glucose tolerance, diabetes mellitus, hypertension, and coronary artery disease increased, the levels of triglyceride (TG), low density lipoprotein cholesterol (LDL-C), fasting plasma glucose, 2 hour plasma glucose, and fasting insulin increased as well, while the level of high density lipoprotein cholesterol (HDL-C) decreased. Meanwhile, all atherosclerotic parameters increased. Multivariate regression analysis showed that TG, total cholesterol, HDL-C, LDL-C levels, and ln(HOMA-IR) were related to IMT, hence were risk factors for IMT increase.</p><p><b>CONCLUSION</b>Insulin resistance is implicated in atherogenesis.</p>
