Efficacy and Safety of SGLT-2 Inhibitors in Acute Myocardial Infarction: A Systematic Review and Meta-Analysis

Since there is no specific recommendation of sodium-glucose cotransporter-2 (SGLT-2) inhibitors in acute myocardial infarction (MI), this systematic review and meta-analysis was performed to address this lack of evidence. Scopus, Embase, PubMed, Web of Sciences, and Cochrane Library were searched from inception until May 30, 2024. We used both random and fixed-effects models for data analyses. Odds ratio (OR) and standard means difference (SMD) were performed for binary and continuous variables, respectively. Nine studies including five randomized clinical trials (RCTs) and four observational studies including 15,595 individuals with acute MI were entered. Overall, SGLT-2 inhibitors are significantly associated with a reduction of hospitalization for heart failure (OR, 0.78; 95% CI, 0.63 to 0.97; P =  .02; I² = 0%) and all-cause mortality (OR, 0.55; 95% CI, 0.38 to 0.81; P =  .002; I² = 0%) based on the RCTs and observational studies, respectively. SGLT-2 inhibitors also significantly improved the left ventricular ejection fraction (SMD, 0.36; 95% CI, 0.02 to 0.70; P =  .04; I² = 62%) among RCTs. Further evaluation of these drugs also revealed an acceptable safety profile without any major adverse events. In conclusion, although SGLT-2 inhibitors may have some clinical benefits among acute MI individuals, further RCTs are still needed to provide robust evidence regarding the use of SGLT-2 inhibitors in this setting.
