Abstract

The aim of this study was to investigate the effects of SGLT2 inhibitors (SGLT2i) on patients with heart failure (HF) and reduced ejection fraction, with or without diabetes. A systematic review of randomized controlled trials (RCTs) was conducted, comparing SGLT2i to a placebo for HF patients. Relevant studies from PubMed, Web of Science, and EMBASE were searched from inception to July 2021, without any language restrictions. The pooled effect was estimated using the odds ratio (OR) and 95% confidence interval (CI). Depending on the heterogeneity test results, either random effects or fixed effects models were selected to estimate the pooled effects. Sensitivity analysis was conducted by gradually removing each study to evaluate the results' stability. A total of 5 RCT studies were included in the analysis. The fixed‑effects model demonstrated that the patients in the SGLT2i group had a lower risk of hospitalization for HF/cardiovascular death (OR=0.72; 95% CI, 0.67‑0.78), P<0.0001; I2=0.0%, P=0.966), cardiovascular death (OR=0.84, 95% CI (0.77, 0.93), P<0.0001; I2=0.0%, P=0.633), hospitalization for HF (OR=0.69, 95% CI (0.63, 0.75), P<0.0001; I2=0.0%, P=0.933), and all‑cause mortality (OR=0.79, 95% CI (0.71, 0.89), P<0.0001; I2=3.3%, P=0.376) compared to the placebo group. Sensitivity analysis showed that the pooled effect value remained stable within the corresponding range, even after each study was gradually removed. In conclusion, SGLT2i can reduce the risk of HF hospitalization, cardiovascular death, and all‑cause mortality in patients with HF and a reduced ejection fraction, regardless of the presence or absence of diabetes.
