A meta-analysis compared the benefit of heart failure therapy with SGLT2 inhibitors versus placebo in women and men showing a risk reduction for women.

Currently, SGLT2 inhibitors form part of the guideline-recommended standard-of-care in the treatment of heart failure with various ejection fractions, as they have demonstrated benefits in cardiac and renal protection, independent of HbA1c, blood pressure, weight, and kidney function [1,2]. In heart failure trials, women are mostly underrepresented leading to a lack of sex-specific cardiovascular (CV) outcome data [1,3]. To gain further insight into this matter, Dr Mounica Vorla (University of Louisville School of Medicine, KY, USA) and colleagues performed a meta-analysis of randomised, placebo-controlled trials that provided results stratified by sex [1]. Pooled risk ratios (RR) for the primary composite outcomes were determined using a random effects model that included data from 11 studies.

For women, this comparison of SGLT inhibition with placebo led to a pooled RR of 0.76 (95% CI 0.69–0.82; P<0.00001). For men, the pooled RR was 0.80 (95% CI 0.73–0.87; P<0.00001). Furthermore, the results of the meta-analysis observed reductions in all-cause and CV death, along with hospitalisation for heart failure. Of note, the study authors conceded some limitations to their analysis, including the lack of patient-level data and heterogeneity between the included trials.
