OBJECTIVE: To evaluate the role of sodium-glucose cotransporter-2 (SGLT2) inhibitors in patients with heart failure with preserved ejection fraction (HFpEF).

DATA SOURCES: A literature search of PubMed, the Cochrane Library, and Google Scholar databases (January 2015 to June 20, 2023) was performed with keywords: sodium-glucose co-transporter 2 inhibitors OR SGLT2 inhibitors OR bexagliflozin OR canagliflozin OR dapagliflozin OR empagliflozin OR ertugliflozin OR sotagliflozin AND heart failure OR heart failure with preserved ejection fraction, and terms related to CV outcomes including cardiovascular death, hospitalization, hospitalization for heart failure, mortality, death, and major adverse cardiovascular event (MACE).

STUDY SELECTION AND DATA EXTRACTION: The reference list from retrieved articles as well as relevant review articles was considered. Pivotal randomized controlled trials and meta-analyses with a primary or secondary end point of CV death or heart failure hospitalization were included. Studies conducted solely in a diabetic patient population were excluded.

DATA SYNTHESIS: Dapagliflozin and empagliflozin, in a broad population of heart failure patients including, HFrEF, HFmrEF, HFpEF, and without diabetes, have shown consistent improvement in the combined outcome of CV death and hospitalization for heart failure (HR 0.80, 95% CI 0.73-0.87) and in the reduction of heart failure hospitalizations (HR 0.74, 95% CI 0.67-0.83). In patients with HFpEF, cardiovascular mortality was not demonstrated (HR 0.88, 95% CI 0.77-1.00). Rates of adverse events were low.

RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: Patients with HFpEF and NYHA class II-III with frequent symptoms or hospitalizations for heart failure derive the most benefit from SGLT2 inhibitors with an overall goal of a reduction in heart failure hospitalizations.

CONCLUSIONS: The treatment of HFpEF has made progress, but there is still work to be done. Now, SGLT2 inhibitor therapy can be used to further help with symptom control and reduce overall hospitalizations for heart failure.
