Key result
Endothelial SIRT3 deficiency drives HFpEF by altering metabolism and promoting microvascular rarefaction.
Why the study?
Despite its rising prevalence, the pathophysiology of HFpEF remains poorly understood and its optimal treatment remains undefined.
SIRT3-mediated endothelial metabolism and coronary microvascular rarefaction are highlighted as major contributors to the pathophysiology of HFpEF.

Endothelial SIRT3 may drive HFpEF microvascular pathology; leaves open whether targeting it alters clinical outcomes.
Zeng et al. (2019) conducted a review in Heart Failure With Preserved Ejection Fraction (HFpEF). SIRT3 deficiency in endothelial cells alters glycolytic metabolism and promotes microvascular rarefaction, contributing to the development of heart failure with preserved ejection fraction.
