Mechanical dysfunction may drive RV inefficiency in IPAH; hypothesis-generating and should not yet change practice.
Is right ventricular failure in idiopathic pulmonary arterial hypertension associated with inefficient myocardial oxygen utilization?
Reduced mechanical efficiency in right ventricular failure secondary to idiopathic pulmonary arterial hypertension is driven by mechanical dysfunction rather than a metabolic shift.
Wong et al. (2011) studied this question.
