Description preview
Heart failure (HF) with preserved ejection fraction (HFpEF) is a prevalent disorder; however, our treatment
options are limited. Studies show that endothelial cell (EC) dysfunction precedes the development of HFpEF and
is a key player in the pathogenesis of this disorder. Hexokinases (HK) catalyze glucose phosphorylation, and
one HK isoform (HK1)…
