The goal of this study is to better understand the effects of a sodium-glucose transport protein 2 inhibitor, dapagliflozin, added on to standard of care on heart and lung function and circulating metabolites (substances created when our bodies break down food, drugs, or its own tissues) in patients with chronic kidney disease.

Evidence of subclinical heart failure with preserved ejection fraction at their pre-exercise echocardiogram (defined as meeting 3/5 of the American Society of Echocardiography (ASE) criteria for diastolic dysfunction [septal e'<7 cm/wc, average E/e' ratio>14, left atrial volume index >34 mL/m2, and peak TR velocity >2.8 m/sec] or absolute left ventricular longitudinal strain < 18%, left atrial reservoir strain (LARS) < 25% on 2d speckle tracking echocardiography), lack of augmentation of LVLS or LARS during exercise, or peak VO2 Females: ≤ 18 mL/kg/min, peak VO2 Males: ≤ 20 mL/kg/min on cardiopulmonary exercise testing.
