Does impaired mitochondrial biogenesis precede heart failure in right ventricular hypertrophy in congenital heart disease?
Impaired mtDNA replication causes early and progressive depletion of mtDNA in the RV of the patients with congenital heart disease during the transition from hypertrophy to failure. Decreased mtDNA content probably is a sensitive marker of mitochondrial injury in this patient population.
In obese, nondiabetic, hypertensive people, left ventricular mass is associated with circulating glucose and insulin levels.
