Heart rate changes during altitude travel in pulmonary hypertension
Part of Heart & circulation, Lungs & breathing clinical trials.
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.
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 (like Quito).
- You have been diagnosed with pulmonary arterial hypertension (PAH) and are stable on your current treatment.
- You are in NYHA functional class I to III (able to do daily activities with mild or no symptoms).
- You have not traveled to altitudes below 2000 meters in the past 4 weeks.
- You do not have severe lung disease, severe smoking (more than 20 cigarettes a day), or low oxygen levels at rest.
- You do not have uncorrected heart defects or significant anemia.
