Brief summary: Obesity is closely associated with an increased risk of cardiomyopathy because of the high metabolic activity of excessive fat while effective treatment of obesity-related cardiomyopathy is currently unsolved. Sodium-glucose cotransporter-2 inhibitors (SGLT2-i) are a class of diabetic medications. Besides improving glucose control, SGLT2-i has been shown to be able to reduce the bodyweight as well as the mortality and hospitalization rates for heart failure and cardiovascular disease in the type 2 diabetes patients. It has been proposed that the heart protection by SGLT2-i might be caused by modulating the production of adipokine and cytokine. The investigators will enrolled 40 patients (diabetes mellitus with BMI\>27 Kg/m2) from obesity weight-reduction clinics: 1) 20 patients treated with SGLT2-i (CANA) and regular weight-reduction plan; 2) 20 patients with regular weight reduction plan, without CANA, for 4 weeks. The investigators will compare the variation of Fibroblast growth factor-21 (FGF21) related proteins and RNA between these 2 groups of subjects. The investigators will arrange cardiac ultrasound, hepatic MRI and fibroscan, body composition dual energy x-ray absorptiometry to evaluate the possible mechanisms underlying the liver and heart modification process, as a scientific basis for precision medicine in the future. Conclusions: SGLT2-i treatment may increase the concentration of FGF21, either in the liver or heart, thus to protect the high-fat diet induced obesity associated heart dysfunction by activating FGF21 downstream protein expression.

Detailed description: The investigators will enrolled 40 diabetes mellitus with BMI\>27 Kg/m2 patients from obesity weight-reduction clinics and will compare the variation of FGF21 related proteins between these 2 groups of subjects. Serial examinations will evaluate the possible mechanisms underlying the protective mechanism. This investigation expect that SGLT2-inhibitor can increase the concentration of FGF21 in the heart by increasing FGF21 in the liver, thereby modifying associated protein expressions and ultimately improving cardiac function and patient outcomes.
