Sodium-glucose cotransporter 2 (SGLT2) inhibitors have been shown to prevent heart failure and reduce cardiovascular death in patients with type 2 diabetes (T2DM) and cardiovascular disease (CVD). Whether or not SGLT2 inhibitors improve indices of cardiorespiratory fitness (CRF), an independent predictor of mortality in patients with CVD, remains unknown. We evaluated the effects of empagliflozin on indices of CRF in patients with T2DM. Twenty patients with T2DM received either empagliflozin 10 mg or usual care. Baseline and 3- to 6-month post-treatment measurements of CRF were evaluated using cardiopulmonary exercise testing on a cycle ergometer. Treatment with empagliflozin led to an increased peak oxygen consumption (VO2), reduction in VE/VCO2 slope, and improvement in heart rate recovery. Our results suggest that SGLT2 inhibitors may improve markers of CRF in patients with T2DM. This may help provide important clues into the mechanism of benefit of SGLT2 inhibitors in clinical trials and provide a translational framework for the ongoing large studies of SGLT2 inhibitors in the treatment of heart failure.
