Walking distance at high altitude vs. sea level in pulmonary hypertension
Part of Heart & circulation, Lungs & breathing clinical trials.
This study compares how far people with pulmonary arterial hypertension (PAH) can walk in six minutes at high altitude versus at sea level. Understanding this difference may help doctors better tailor care for patients living at high altitudes.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old.
- You have been diagnosed with pulmonary arterial hypertension (PAH) and your condition is stable on your current medications.
- You live permanently at an altitude above 2,600 meters (about 8,530 feet).
- Your symptoms are mild to moderate (NYHA functional class I, II, or III).
- You have not traveled below 2,000 meters (about 6,560 feet) overnight in the past 4 weeks.
- You do not have severe lung disease, heavy smoking (more than 20 cigarettes a day), very low oxygen levels at rest, uncorrected heart defects, or significant other health problems.

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.
This study compares how well your lungs work when you are at high altitude (your home) versus when you visit sea level. It aims to understand how altitude affects people with pulmonary arterial hypertension, which is high blood pressure in the lungs.
This study compares how the heart and lungs respond at high altitude versus sea level in people with pulmonary arterial hypertension (PAH), a type of high blood pressure in the lungs. It may help doctors understand if living at high altitude affects symptoms and treatment.
This study compares how far healthy people can walk in six minutes when they are at high altitude versus at low altitude. It might help us learn how living at high altitudes affects fitness and exercise capacity.
This study looks at how the heart and lungs respond when people with pulmonary hypertension travel from low to high altitude. It may help doctors understand how to better care for patients living at high altitudes.
This study looks at how your heart rate changes when you travel from high altitude (about 2850 meters) down to sea level and back up again. It may help doctors understand if such travel is safe for people with pulmonary hypertension.
