چکیده
BACKGROUND The aim of this study was to evaluate the relationship between postprandial glucose level and atherosclerosis in patients without diabetes and cardiovascular disease by determining carotid ultrasonographic variables and serum levels of 1,5-anhydroglucitol (1,5-AG). METHODS The subjects were 72 patients without diabetes and cardiovascular disease being treated for hypertension or dyslipidemia. The clinical characteristics of all subjects, including the serum level of 1,5-AG, which appears to be well suited for monitoring postprandial hyperglycemia, were evaluated after an overnight fast. The average intima-media thickness (IMT) and the average pulsatility index (PI) of the right and left common carotid arteries were determined with high-resolution ultrasonography and used as ultrasonographic variables. The subjects were divided into a lower 1,5-AG group (n = 36) and a higher 1,5-AG group (n = 36). We evaluated the relationship between clinical characteristics and ultrasonographic variables of the carotid artery in both groups. RESULTS The average PI in the Lower 1,5-AG group was significantly higher than that in the Higher 1,5-AG group, but the average IMT did not differ between the groups. Linear regression analysis, with the ultrasonographic variables as the dependent variables, with 1,5-AG as the independent variable, and adjusted for other clinical characteristics, showed significant correlation between 1,5-AG and the PI but not between 1,5-AG and IMT. CONCLUSION Our results suggest that postprandial hyperglycemia increases carotid artery stiffness, but not morphological change, in patients without diabetes or cardiovascular disease.

Carotid artery Intima-Media thickness and cardiovascular risk factors in chronic hemodialysis patients
Introduction: Common carotid artery intima-media thickness (CCA-IMT) correlates with cardiovascular mortality in patients under hemodialysis. In this investigation, we evaluated relationship between CCA-IMT with dependent and independent cardiovascular risk factors in chronic hemodialysis patients. Methods: In this cross-sectional study, 51 chronic hemodialysis patients, (31 males and 20 fema...
متن کاملCarotid Intima Media Thickness in Nondiabetic Hypertensive Nigerians: Role of Fasting and Postprandial Blood Glucose
Background/Aims. Carotid intima media thickness (CIMT) tracks atherosclerotic vascular disease. Hypertension and diabetes chiefly contribute to atherosclerosis with 75% of symptomatic cardiovascular disease cases having dysglycaemia even in normal cases. Hypothesising that postprandial hyperglycaemia contributes to cardiovascular morbidity, we sought to determine if any relationship existed bet...
متن کاملAssociation of circulating omentin-1 level with arterial stiffness and carotid plaque in type 2 diabetes
BACKGROUND Adipokines contribute directly to the atherosclerotic process, connecting metabolic disorders such as obesity and diabetes to cardiovascular disease. Omentin-1 is a recently discovered novel adipokine, so data about the relationship of this adipokine to vascular health in type 2 diabetes is limited. METHODS We enrolled 60 people with type 2 diabetes, with or without carotid plaque,...

Abstract Objective: Diabetes mellitus is the most common metabolic disease. One of the most common problems in diabetic patients is atherosclerotic cardiovascular disease which is induced by hyperlipidemia. Impaired lipid metabolism resulting from uncontrolled hyperglycemia has been implicated in cardiovascular complications in diabetic patients. Also, glycated hemoglobin (HbA1c) has been rega...
