Heart failure with preserved ejection fraction (HFpEF) has limited treatment options and remains a medical challenge. HFpEF is characterized by diastolic dysfunction with a normal ejection fraction. Previous findings have shown that inhibiting histone deacetylase 6 (HDAC6) alters the mechanisms contributing to dilated cardiomyopathy.
Several genetic studies in a range of model organisms have pointed to an important role for the B-cell lymphoma 2 (BCL2)-associated athanogene 3 (BAG3) gene in the maintenance of cardiac function.
