Liu Y, et al. - A comparative scrutiny was carried out of the effects of Liraglutide and Metformin alone or combined treatment on the cardiac function in type 2 diabetes mellitus (T2DM) patients complicated with coronary artery disease (CAD). Owing to the similar glycemic control, the Liraglutide (1.2 mg/d) monotherapy exhibited better effects than either Metformin alone or the combination of Liraglutide and Metformin on lipid metabolism and cardiovascular function.
