Abstract
Background Sodium-glucose co-transporter 2 (SGLT2) inhibitor which is a type of drug used for the treatment of diabetes mellitus, has been reported by many trials that it could be beneficial for patients with established heart failure. A meta-analysis on this subject could obtain more reliable estimates of the efficacy and safety outcomes. Methods A systematic review and meta-analysis of randomized, placebo-controlled trials of SGLT2 inhibitor in patients with heart failure was conducted. We searched PubMed, Cochrane Library, and Web of Science for trials published from inception to March, 2018. PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) was used to conduct the review. For quality assessment of included studies. The methodological quality of the included trials was assessed using the Cochrane tool for assessing randomized clinical trials (RCT). Efficacy outcomes included hospitalization for heart failure and all-cause death. Safety outcomes consisted of serious adverse event (SAE) and volume depletion. Results We included data from 5 identified studies and 8775 patients (aged 64.9, female 29.8%). A total of 3930 (44.8%) patients were known to have diabetes mellitus. Compared with placebo, SGLT2 inhibitor decrease the incidence of hospitalization for heart failure (RR 0.692; 95%CI, 0.611-0.784 P<0.001), and all-cause death (RR 0.824; 95%CI, 0.736-0.922 P=0.001). The incidence of SAE in patients with a treatment of SGLT2 inhibitor was low (RR 0.869; 95%CI, 0.779-0.970 P=0.012). SGLT2 inhibitor didn’t increase the incidence of volume depletion (RR1.165, 95%CI, 0.977-1.390 P=0.089). Conclusion Our results confirm that SGLT2 inhibitor is effective and safe for patients with heart failure regardless of presence of diabetes mellitus.
