Key result
SGLT2 inhibitors reduce HF hospitalizations and CV death with less hemodynamic compromise than loop diuretics.
Why the study?
SGLT2 inhibitors have redefined heart failure treatment, but the therapeutic balance and integration with loop diuretics require clarification.
Do SGLT2 inhibitors reduce hospitalizations and cardiovascular mortality and improve cardiorenal balance compared to or in combination with loop diuretics in patients with heart failure?
Do SGLT2 inhibitors reduce hospitalizations and cardiovascular mortality and improve cardiorenal balance compared to or in combination with loop diuretics in patients with heart failure?
SGLT2 inhibitors provide cardiorenal protection and may reduce chronic loop diuretic requirements in heart failure patients, supporting their early and integrated use as a cornerstone of therapy.

Supports integrating SGLT2 inhibitors with loop diuretics in HF; extends RCT evidence to cardiorenal strategies.
Sodium-glucose cotransporter-2 inhibitors (SGLT2i) have redefined the therapeutic landscape of heart failure (HF), both with reduced (HFrEF) and preserved (HFpEF) ejection fraction. Historically, treatment has relied on diuretics to relieve congestion, with limited prognostic impact and dose-related adverse effects. SGLT2i, originally developed for type 2 diabetes mellitus, have demonstrated in randomized trials a significant reduction in hospitalizations and cardiovascular mortality, with benefits extending to non-diabetic patients. SGLT2 inhibitorsTheir mechanism combines moderate osmotic natriuresis, selective reduction of extracellular volume, renal protection, and minimal neurohormonal activation. In contrast to loop diuretics, which induce rapid volume depletion and RAAS activation, SGLT2i stabilize sodium-water balance without significant hemodynamic compromise. In clinical practice, their combination with diuretics requires careful titration to prevent hypovolemia, hypotension, and renal dysfunction, especially in frail elderly patients. Evidence suggests that SGLT2i may reduce chronic diuretic requirements, improve renal function, and provide additional cardiovascular protection. These findings support their early and integrated use, positioning SGLT2i as a cornerstone in the contemporary management of heart failure.

(1) et al. (2025) conducted a review in Heart failure. SGLT2 inhibitors vs. Loop diuretics was evaluated. SGLT2 inhibitors reduce hospitalizations and cardiovascular mortality in heart failure and provide cardiorenal protection without the significant hemodynamic compromise of loop diuretics.
