Right ventricular pressure overload alters cardiac lipid composition

Right ventricular (RV) failure due to pressure load is an important determinant of clinical outcome in pulmonary hypertension, congenital heart disease and left ventricular failure. The last decades it has become clear that metabolic dysregulation is associated with the development of RV-failure. However, underlying mechanisms remain to be unraveled. Recently, disruption of intracardiac lipid content has been suggested as potential inducer of RV failure. In the present study, we used a rat model of RV-dysfunction and aimed to obtain insight in temporal changes in RV-function, -remodelling and -metabolism and relate this to RV lipid content.
