Walking distance at sea level vs high altitude in pulmonary hypertension
Part of Lungs & breathing clinical trials.
This study compares how far you can walk in six minutes at sea level versus at high altitude (where you live) after returning to high altitude. The goal is to see if being at high altitude affects your exercise capacity, which may help guide future care.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old.
- You live permanently at an altitude above 2600 meters (about 8500 feet).
- You have been diagnosed with pulmonary arterial hypertension (PAH), a condition that causes high blood pressure in the lungs.
- Your PAH is stable on your current treatment.
- You have mild to moderate symptoms (NYHA class I to III), meaning you can still do some daily activities without severe breathlessness.
- You have not stayed overnight at altitudes below 2000 meters (about 6500 feet) in the past 4 weeks.
