The study aims to enroll patients with type 2 diabetes with poor glycemic control, and with coronary artery disease not requiring revascularization, who have already undergone, under routine cardiological assessment, a positron emission tomography (PET) 13NH3 scan in order to assess the cardiovascular function. Thus, the study aims to assess whether the improvement in cardiac metabolism obtained with dapagliflozin is greater than that obtained with normal clinical practice (according to Standards of Care).
