- No recent initiation of pulmonary vasodilator in the last 60 days
- Pulmonary arterial hypertension by right heart catheterization (Mean PA pressure ≥ 20 mmHg with PVR>2 Wood units) with no evidence of heart failure with preserved ejection fraction (exercise PCWP <25 mm Hg).
- Symptomatic PAH patients with plan to undergo exercise RHC for reassessment of exertional symptoms
- Healthy Controls:
- Informed consent obtained before any trial-related activities. Trial-related activities are any procedures that are carried out as part of the trial, including activities to determine suitability for the trial.
- No known diagnosis of heart failure

- Wheelchair bound or orthopedic inability to exercise
- Chronic hypoxemia with inability to exercise without oxygen supplementation (PAH Subjects) or need for oxygen supplementation (Healthy Controls)
