Exercise hemodynamics predict pulmonary arterial hypertension in BMPR2 mutation carriers

Exercise hemodynamics are recommended for early detection of pulmonary arterial hypertension (PAH) and have been suggested to be predictive of future development of PAH in high-risk populations such as bone morphogenetic protein receptor type 2 (BMPR2) mutation carriers. However, the optimal exercise hemodynamic screening parameter remains to be determined. Recent data suggest that pulmonary vascular distensibility coefficient (α) may serve as a useful parameter for early detection of PAH.
