Genomic, Proteomic, and Metabolic Comparisons of Small Animal Models of Heart Failure With Preserved Ejection Fraction: A Tale of Mice, Rats, and Cats.

Heart failure with preserved ejection fraction (HFpEF) remains a medical anomaly that baffles researchers and physicians alike. The overall phenotypical changes of diastolic function and left ventricular hypertrophy observed in HFpEF are definable; however, the metabolic and molecular alterations that ultimately produce these changes are not well established. Comorbidities such as obesity, hypertension, and diabetes, as well as general aging, play crucial roles in its development and progression.

The Role of Mitochondrial Dysfunction in Preeclampsia: Causative Factor or Collateral Damage?

Preeclampsia, new onset hypertension in pregnancy, affects ~5%-10% of the world's population. Preeclampsia is the leading cause of morbidity and mortality for both the mother and fetus. As of today, there is no cure for this disease except for delivery of the fetal-placental unit.
