SGLT2 Inhibitors in Diabetic Patients With Cardiovascular Disease or at High Cardiovascular Risk: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
Abstract
Objective: To investigate the effect of sodium-glucose cotransporter-2 inhibitors (SGLT2i) in patients with diabetes with cardiovascular disease (CVD) or at high cardiovascular risk.
Design: Systematic review and meta-analysis of randomized controlled trials (RCTs).
Data sources: Pubmed, Embase, the Cochrane Library, and ClinicalTrial.gov from their inception to August 28, 2021.
Review methods: Randomized control trials (RCTs) assess the effects of SGLT2i in patients with diabetes with cardiovascular disease or at high cardiovascular risk. Primary outcomes included the composite outcome of cardiovascular death (CV death) and hospitalization for heart failure (HHF), HHF, and renal composite outcomes. Secondary outcomes included major adverse cardiovascular events (MACE), CV death, all-cause mortality, and change from the baseline in HbA1c. Additionally, we assessed the effects of treatment in prespecified subgroups on the combined risk of primary and secondary outcomes. These subgroups were based on history of heart failure (HF), estimated glomerular filtration rate (eGFR) levels, and history of hypertension (HTN). A meta-analysis was carried out by using fixed effect models to calculate hazard ratio (HR) or mean difference (MD) between the SGLT2i administrated groups and the control groups.
Results: Four major studies (n = 42,568) were included. Primary outcomes showed that SGLT2i was associated with significantly lower risk of CV death/HHF (HR, 0.90; 95% confidence…
