Patients with type 2 diabetes mellitus (DM) have higher risk of major cardiovascular events (MACE) and renal disfunction. The Sodium-glucose cotransporter-2 inhibitors (iSGLT2) reduces hyperglycemia in patients with type 2 DM and have multiple metabolic effects, lowering primary composite cardiovascular outcomes and progression to renal failure. 25% of patients with Stable Ischemic Heart Disease (SIHD) undergoing PCI are diabetics being one of the most prevalent and important risk factors for the development of contrast induced nephropathy (CIN). The occurence of CIN is associated with higher rates of death, loss of renal function, necessity of dialysis and increase of health care costs. In this pilot study we sought to evaluate if the iSGLT2 would prevent periprocedural complications - such as periprocedural CIN and MI - in type 2 DM patients undergoing PCI through the assessment of renal and myocardial biomarkers

• Prospective, unblinded, randomized (1:1), single-center pilot study of 40 patients allocated to one of the treatment arms (OMT + empaglifozin or OMT). Strategies to reduce Contrast-induced acute kidney injury will be used in both study arms
• The study population will be composed of patients with type II diabetes mellitus and coronary artery disease (CAD) suitable for PCI of one or more coronary vessels
• After discharge, all subjects will be clinically followed-up during hospitalization and for 30 days after PCI.
• Unless contra-indicated, all patients will receive intravenous hydration during 12 hours pre- and 12 hours post-PCI. Saline (NaCl 0.9%) infusion is recommended at a dose of 1 ml / kg body weight per hour and reduced to 0.5 ml/kg/h for those at high risk of volume overload (e.g. reduced left ventricular function or overt heart failure). All nephrotoxic drugs will be suspended at least 24 hours before the procedure.
• Operators will be strongly recommended to follow strict strategies to reduce the total volume of contrast for all patients
• All percutaneous procedures will be performed using non-ionic, low-osmolar or iso-osmolar, iodine-based contrast media
• The study groups will be compared according to the intention-to-treat principle. Categorical variables will be compared by Fisher's exact testing and continuous variables by Student's T testing. Time-dependent events will be estimated by the Kaplan-Meier method and compared by Hazards Cox modeling or log-rank test
