Oxygen therapy for chronic heart failure
Part of Heart & circulation clinical trials.
This study tests whether adding hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber) to standard heart failure medications can improve symptoms and heart function for people with chronic heart failure and a weak heart pump.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have chronic heart failure with a weakened heart pumping ability (LVEF of 40% or less).
- You have had heart failure symptoms (like shortness of breath or fatigue) for at least 3 months.
- You are on a stable dose of all four standard heart failure medications (ARNI/ACEI/ARB, beta-blocker, MRA, and SGLT2 inhibitor) for at least 2 weeks.
- You have not had a heart attack, unstable angina, or been hospitalized for heart failure in the past few weeks.
- You do not have conditions like untreated collapsed lung, severe claustrophobia, active bleeding, or certain other medical issues that would make hyperbaric oxygen therapy unsafe.

This trial studies how well oxygen therapy works for people with long-term lung or heart conditions who have sudden breathing problems. It aims to find the best way to monitor breathing at home to improve care.
This trial studies a breathing-focused treatment to help people with HFpEF (a type of heart failure) feel and function better. It may help improve daily activity by addressing breathing limits that commonly come with this condition.
This study tests whether breathing high-flow oxygen through a nasal tube during exercise helps people with heart failure exercise longer and feel better. Researchers will compare how well patients do with and without this extra oxygen during cardiac rehabilitation.
This study tests whether two noninvasive breathing/oxygen treatments after cardiac surgery help improve heart function. It may benefit people with weak pumping function who are recovering in the hospital and can safely use these devices.
This trial tests whether pulmonary rehabilitation (supervised breathing and activity training) improves outcomes for adults who need high-flow oxygen. You may be eligible if your breathing and heart/vital signs are stable and your oxygen level is above a certain threshold.
This trial tests whether high-intensity resistance training in water can improve strength and function in people with chronic heart failure. It's designed for those who are stable on medication and not yet in a rehab program.
