A Systematic Review and Meta-Analysis of the Efficacy and Safety of Sodium-Glucose Cotransporter-2 Inhibitor in Patients Using Left Ventricular Assist Devices.

Sodium-glucose cotransporter-2 inhibitors (SGLT2-i) have been shown to reduce risks of clinical events in patients with heart failure (HF). However, data on the use of SGLT2-i in patients with left ventricular assist devices (LVADs) are scarce. We thought to assess the efficacy and safety of SGLT2-i in patients with LVADs. A systematic search was conducted in PubMed, Scopus, Web of Science, Embase, and Cochrane from inception to November 2024. We used all relevant words for "SGLT2-i" and "LVAD" to search in databases, and we included studies and published abstracts in peer-reviewed journals of studies that assessed SGLT2-i in patients with LVAD. Four studies and seven abstracts totaling 228 patients using SGLT2-i were included. Empagliflozin, Dapagliflozin, and Canagliflozin were the used SGLT2-i across the included studies. Pooled analysis showed that SGLT2-i significantly improved ejection fraction (EF) (Mean= 4.2, 95% CI [1.22, 7.19]) and hemoglobin A1c (HbA1c) (Mean = -0.44, 95% CI [-0.79, -0.09]) from baseline. However, no significant changes in B-type natriuretic peptide (BNP), or glomerular filtration rate (GFR) were noticed. Other outcomes of interest not included in the meta-analysis did not show significant changes, such as cardiac index (CI), left ventricular end-systolic diameter (LVESD), left ventricular end-diastolic diameter (LVEDD), mean arterial pressure (MAP), or mean pulmonary artery pressure (MPAP). The pooled percentage of people with driveline infection was 9%, 95% CI (3, 19). SGLT2-i effectively improves EF and HbA1c in patients using LVAD. Further adequately powered randomized studies are warranted to ascertain its clinical efficacy and safety in that unique population.
