Reversing endothelial dysfunction with empagliflozin to improve cardiomyocyte function in cardiorenal syndrome.

Sodium-glucose cotransporter 2 inhibitors offer cardiovascular and renal benefits in patients with chronic kidney disease through not yet clearly defined mechanisms. Juni et al. showed that sodium-glucose cotransporter 2 inhibitor empagliflozin exposure in vitro can restore cardiomyocyte function by counteracting harmful effects of uremic serum on the endothelium-cardiomyocyte crosstalk between endothelial cells and cardiomyocytes. The author's findings improved our understanding of cardiovascular impairment in chronic kidney disease and provided new perspectives for the beneficial effects of sodium-glucose cotransporter 2 inhibitor therapy.
