Great progress has been made in the treatment of heart failure with sodium-dependent glucose transporter 2 inhibitor (SGLT2i) in the recent years. The outcome studies in the field of cardiovascular diseases have opened the door for SGLT2i to improve cardiovascular prognosis. DAPA-HF, EMPEROR-Reduced, SOLOIST-WHF and other pivotal trials have extended the indications of SGLT2i to heart failure with reduced ejection fraction. The clinical studies on the management of heart failure with preserved ejection fraction with SGLT2i are also in progress. It is believed that there will be more evidence to support the benefits of SGLT2i for patients with heart failure in the future.
