IMPORTANCE Sodium-glucose cotransporter-2 inhibitors (SGLT2i) improve outcomes in patients with heart failure and a reduced ejection fraction (HFrEF). The association with cardiac remodeling has not been investigated. OBJECTIVE To investigate the outcome of the SGLT2i empagliflozin, compared with placebo, on cardiac remodeling in patients with HFrEF. DESIGN, SETTING, AND PARTICIPANTSThis exploratory post hoc analysis included participants with stable HFrEF and ejection fractions of 40% or less, who were randomly enrolled in an investigator-initiated, multicenter, double-blind, placebo-controlled randomized clinical trial
