Sodium-glucose co-transporter 2 inhibitors-the first successful treatment for heart failure with preserved ejection fraction?

Out with the Old and In with the New: Primary Care Management of Heart Failure with Preserved Ejection Fraction

Primary care plays an integral role in the management of complex, chronic disease states such as heart failure. However, there is a disconnect between the characteristics of those recruited into clinical trials and those managed in the real world, which means the contribution and consideration of primary care in current guidelines is suboptimal. In this article, the authors explore key issues in the diagnosis and management of heart failure that need to be addressed from a primary care perspective. This article focuses on the issue of heart failure with preserved ejection fraction and the integration of new clinical epidemiology and trial evidence into clinical practice. In response, the authors advocate for dedicated guidelines for the primary care management of heart failure, the development of strategies to facilitate communications between health professionals in acute and community care and a renewed focus on researching optimal models of heart failure care in the community.

Sodium-Glucose Cotransporter-2 Inhibitor Use is Associated with a Reduced Risk of Heart Failure Hospitalization in Patients with Heart Failure with Preserved Ejection Fraction and Type 2 Diabetes Mellitus: A Real-World Study on a Diverse Urban Population

BACKGROUND

Limited evidence-based therapies exist for the management of heart failure with preserved ejection fraction (HFpEF). Sodium-glucose cotransporter-2 inhibitor (SGLT2i) use in patients with systolic heart failure (HFrEF) and type-2-diabetes mellitus (T2DM) is associated with improved cardiovascular (CV) and renal outcomes.

OBJECTIVE

We sought to examine whether there is an association of SGLT2i use with improved CV outcomes in patients with HFpEF.

PATIENTS AND METHODS

We conducted a single-center, retrospective review of patients with HFpEF and T2DM. The cohort was divided into two groups based on prescription of a SGLT2i or sitagliptin. The primary outcome was heart failure hospitalization (HFH); secondary outcomes were all-cause hospitalization and acute kidney injury (AKI).

RESULTS

After propensity score matching, there were 250 patients (89 in the SGLT2i group, 161 in the sitagliptin group), with a mean follow-up of 295 days. Univariate Cox regression analysis showed that the SGLT2i group had a reduced risk of HFH versus the sitagliptin group (hazard ratio (HR) 0.13; 95% confidence interval (CI) (0.05-0.36); p < 0.001). The SGLT2i group had a decreased risk of all-cause hospitalization (HR 0.48; 95% CI (0.33-0.70); p < 0.001) and SGLT2i had a lower risk of AKI (HR 0.39; 95% CI (0.20-0.74); p = 0.004).

CONCLUSIONS

The use of SGLT2is is associated with a reduced incidence of HFH and AKI in patients with HFpEF and T2DM.
