Single Administration of α-Glucosidase Inhibitors on Endothelial Function and Incretin Secretion in Diabetic Patients With Coronary Artery Disease – Juntendo University Trial: Effects of Miglitol on Endothelial Vascular Reactivity in Type 2 Diabetic Patients With Coronary Heart Disease (J-MACH) –

摘要

Background: ?Post-prandial hyperglycemia, hyperlipidemia, and endothelial dysfunction play an important role in the pathogenesis of atherosclerosis. Improvement in post-prandial hyperglycemia on α-glucosidase inhibitors (α-GIs) is associated with a risk reduction of cardiovascular diseases, but the post-prandial effects of α-GIs on endothelial function and incretin secretion in type 2 diabetic patients with coronary artery disease (CAD) remain unclear. Methods and Results: ?The post-prandial effects of a single administration of miglitol and voglibose on endothelial function and changing levels of glucose, insulin, lipids, glucagon-like peptide (GLP)-1, and gastric inhibitory polypeptide (GIP) were compared after a standard meal loading in 11 diabetic patients with CAD, using a placebo-controlled cross-over design. The changing levels of glucose, insulin and triglycerides at 60?min were significantly lower in the miglitol group than in the voglibose and placebo groups (all P
