Effects of sodium-glucose cotransporter-2 inhibitors in myocardial infarction patients: A systematic review and meta-analysis.

AIMS: Sodium-glucose cotransporter-2 (SGLT2) inhibitors are known to improve cardiovascular outcomes in individuals with heart failure (HF), type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD). However, their efficacy following myocardial infarction (MI) remains unclear.

MATERIALS AND

METHODS

A systematic search was conducted using PubMed, Embase, Cochrane Library, Web of Science and ClinicalTrials.gov. Primary outcomes included hospitalization for heart failure (HHF), cardiovascular (CV) death, a composite of HHF or CV death, all-cause death, major cardiovascular events (MACE), recurrent MI, severe arrhythmia, renal injury and stroke. Secondary outcomes targeted improvements in left ventricular ejection fraction (LVEF) and left ventricular end-diastolic volume (LVEDV).

RESULTS

Thirteen studies comprising 22 370 patients were included. Meta-analysis revealed that SGLT2 inhibitors reduced HHF (RR 0.69, 95% CI 0.61 to 0.78, p < 0.001), combined HHF or CV death (RR 0.87, 95% CI 0.77 to 0.99, p = 0.028), all-cause mortality (RR 0.82, 95% CI 0.73 to 0.93, p = 0.002), MACE (RR 0.68, 95% CI 0.53 to 0.88, p = 0.004), recurrent MI (RR 0.81, 95% CI 0.69 to 0.94, p = 0.007), severe arrhythmia (RR 0.54, 95% CI 0.34 to 0.85, p = 0.009) and renal injury (RR 0.68, 95% CI 0.53 to 0.87, p = 0.002). Improvement in LVEF (MD 3.96%, 95% CI 2.52 to 5.40; p < 0.001) and LVEDV (MD -5.52 mL, 95% CI -10.21 to -0.83; p = 0.021) was notably greater in the SGLT2 inhibitors group.

CONCLUSIONS

In post-MI patients, we first found that SGLT2 inhibitors significantly lowered the risk of HHF, combined CV death or HHF, all-cause death, MACE, recurrent MI, severe arrhythmias and renal injury. Additionally, SGLT2 inhibitors improved LVEF and LVEDV.
