Sleep apnea and heart balance in pulmonary hypertension
Part of Brain & nervous system, Heart & circulation, Lungs & breathing clinical trials.
This study looks at how sleep-related breathing issues affect heart rate control in people with pulmonary hypertension. It uses a sleep study device to measure oxygen levels and heart rhythm over several nights.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older
- You have a type of pulmonary hypertension called precapillary PH, confirmed by a heart catheterization
- Your doctor has recommended you start a vasodilator medicine for your PH
- You are not using a breathing machine at night (non-invasive ventilation)
- You do not have scleroderma, Eisenmenger syndrome, or a neurodegenerative disease
- You do not have a pacemaker or untreated heart rhythm problems

This trial uses special ultrasound imaging to look at how well the heart works in people newly diagnosed with pulmonary arterial hypertension (PAH). It aims to understand heart changes before and after starting PAH treatment.
This study looks at how sleep apnea affects your heart and blood vessels over time. It uses a sleep study and heart tests to see if certain measurements can predict heart health changes.
This study uses an echocardiogram (heart ultrasound) to check for high blood pressure in the lungs (pulmonary hypertension) in people with obstructive sleep apnea. It may help find hidden heart strain in sleep apnea patients.
This study is looking at a specific sleep-related condition (obstructive sleep apnea) in adults whose blood pressure is not high, and how their blood pressure rhythm changes over the day. If you have sleep apnea, participating could help researchers understand patterns that may affect long-term health.
This study looks at timing mismatches (“dysynchrony”) in the heart and lungs in people with pulmonary hypertension. It may help researchers understand what causes symptoms and how the timing affects heart function.
This study tests whether using CPAP (a breathing machine) for obstructive sleep apnea can improve blood pressure and heartbeat timing. You’ll have blood pressure checked at the start and again after 6 months, along with a sleep evaluation to confirm eligibility.
