SGLT2 inhibitors improve heart failure outcomes through mechanisms independent of glucose lowering, including natriuresis, osmotic diuresis, reduced plasma volume, and improved myocardial energetics via ketone utilization.

SGLT2 inhibitors help the heart by making it work more efficiently. They help remove excess fluid and sodium, reducing strain on the heart, and shift the heart's fuel source to ketones, which are more energy-efficient. This happens regardless of blood sugar levels.

While the exact mechanism by which empagliflozin may impact HF outcomes is not understood, several effects of SGLT2 inhibitors may be of benefit... SGLT2 inhibitors induce osmotic diuresis and natriuresis... The elevated level of beta hydroxybutyrate seen with SGLT2 inhibitors results in a shift in fuel supply... towards the more energy-efficient ketones.
