Exercise capacity correlates with PAH severity and prognosis. However, exercise contraindications and poor patient tolerance might limit its use in clinical practice. We identified that low P ET CO 2 during low‐intensity (FW) exercise is associated with PAH exercise capacity, providing predictive information for PAH risk stratification and prognostication.
