Heart function study for high-altitude pulmonary edema survivors
Part of Genetic & congenital, Heart & circulation, Lungs & breathing clinical trials.
This study looks at how a common heart feature, called a patent foramen ovale (a small flap between the upper chambers), affects the heart's response to low oxygen, such as at high altitudes. Participation may help researchers understand why some people develop fluid in the lungs at high altitude and could lead to better prevention or treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 59 years old.
- You have had a medically diagnosed episode of high-altitude pulmonary edema (fluid in the lungs at high altitude).
- You do not have other heart or blood vessel defects.
- You are physically active and able to do endurance exercise like jogging or cycling.
- You are not taking heart or lung medications, blood thinners, or aspirin.
- You have not had anemia, iron deficiency, or iron supplements in the last 60 days, and you are not pregnant.
- You have not been recently ill (like a cold) in the last 4 weeks.

This trial tests whether high-flow oxygen (delivered through a special nasal tube) works better than standard oxygen therapy for a condition called high-altitude pulmonary edema (HAPE)—fluid buildup in the lungs caused by rapid ascent to high altitude. The study aims to see which approach helps patients breathe better and recover faster.
This study looks at how the right side of the heart responds to low oxygen levels in people who have had high altitude pulmonary edema (HAPE) in the past. It will help researchers better understand right heart function.
This study tests how your heart’s right ventricle handles low oxygen (like at high altitude) in healthy adults. You will be exposed to a low-oxygen environment for a short time to see how your heart responds.
This study is for people living at high altitudes (above 2,500 meters) to understand how the pressure in the arteries of the lungs changes over time and how it affects health. It may help doctors predict and manage heart and lung problems that can occur in high-altitude residents.
This study tests how your heart's right ventricle adapts when you breathe lower-oxygen air (like at high altitude). If you have well-controlled asthma, researchers want to see if your heart handles the challenge differently.
This study looks at how exposure to high altitude changes measurements related to your heart and breathing. It may help scientists better understand health effects of altitude so they can improve safety and care.
