ABSTRACT

BACKGROUND: Recent trials demonstrated the clinical efficacy of sodium-glucose cotransporter-2 inhibitors (SGLT2i) in patients with heart failure (HF), regardless of the presence or absence of type 2 diabetes. These data may allow the use of this innovative drug class in clinical routine for treating these patients.

STUDY QUESTION: We aimed at further clarifying the role of SGLT2i in patients with diagnosis of HF, capitalizing on pooled sample size and heightened power for clinically relevant safety and efficacy outcomes.

DATA SOURCES: We conducted a systematic search of PubMed, reference lists of relevant articles, and Medline database from inception until March 1, 2021.

STUDY DESIGN: This meta-analysis was completed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched for randomized trials that evaluated the cardiovascular effects of SGLT2i in patients with HF. Three investigators independently assessed study eligibility, extracted the data, and assessed risk of bias. Hazard ratios and 95% confidence intervals (CIs) were pooled and meta-analyzed using a random-effect model. Numbers needed to treat (NNT) with the relative 95% CIs were also calculated. The primary outcome was a composite of HF hospitalization or an urgent visit for worsening HF and cardiovascular death.

RESULTS: Three trials were included in the study. Overall, treatment with SGLT2i was associated with a lower risk of the primary composite outcome [hazard ratios 0.73, 95% CI (0.67-0.80), NNT = 11.3]. Similarly, there was a significantly reduced risk of cardiovascular death, all-cause death, HF hospitalization and need for urgent treatment for HF, and HF hospitalization.

CONCLUSIONS: Therefore, the available evidence supports the routine use of these drugs as standard-of-care, also given the highly favorable NNTs.
