简要总结
The purpose of this research study is to find out more about the drug treprostinil via inhaler and the mechanisms of why patients with pulmonary arterial hypertension related to Interstitial Lung disease (PAH-ILD) have limitations during exercise. The investigator is studying treprostinil's effect on patients with PAH-ILD during exercise and its effect on their quality of life after using it for 3 months.

结局指标
主要结局
Cardiac Output Reserve (Qc)
时间窗: Baseline, approximately 35 minutes
Cardiac output reserve (Qc) is the difference between the heart's maximum output during exercise and its resting output. This was measured using the direct Fick method (L/min).
次要结局
- Ventilatory Efficiency (VE/VCO2)(Baseline, approximately 35 minutes)
- Resting Pulmonary Vascular Resistance(Baseline; after 30 minutes of rest)
- Exercise Pulmonary Vascular Resistance(Baseline; approximately 35 minutes)
- Resting Pulmonary Artery Pressure(Baseline; after 30 minutes of rest)
- New York Heart Association (NYHA) Functional Class(Baseline, 3-months)
- Exercise Pulmonary Artery Pressure(Baseline; approximately 35 minutes)
- Resting Right Atrial Pressure(Baseline; after 30 minutes of rest)
- Exercise Right Atrial Pressure(Baseline; approximately 35 minutes)
