Peripheral and coronary endothelial dysfunction in type 2 diabetic patients may be influenced by therapeutics. Using Radial flow monitoring and myocardial perfusion magnetic resonance imaging, we designed a controlled randomized double blind study to test the hypothesis that endothelial dysfunction will be reversed following 3 months of Metformin administration vs gliclazide. 30 patients will be included.
