Acute decompensated heart failure is the fastest growing disease in the world and the leading cause of hospital admissions worldwide. Short term mortality and rehospitalization are extremely high (20-30% within 3-6 months) and there is no therapy available that improves clinical outcome in these patients. Empagliflozin is a selective inhibitor of sodium glucose co-transporter with diuretic and renal- protective properties. In patients with type 2 diabetes at high risk for cardiovascular events, empagliflozin reduced the risk of hospitalization for heart failure by 35%. Based on the promising pharmacological profile of empagliflozin in relation to the needs for treatment of acute decompensated heart failure, we hypothesize that empagliflozin exerts positive effects in acute decompensated heart failure, with or without diabetes,
