Diaphragm stimulation for heart failure
Part of Heart & circulation clinical trials.
This trial tests a device that stimulates your diaphragm (the muscle that helps you breathe) while you have heart failure. It may help improve your breathing and heart function. The study is for people with moderate heart failure symptoms whose heart pumps less blood than normal.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your heart failure symptoms are moderate (class II or III) and you are on the best medications for your condition.
- Your heart's electrical signal (QRS) is normal or only slightly widened (130 ms or less).
- Your heart's pumping ability (ejection fraction) is 40% or less.
- You can walk between 200 and 500 meters in 6 minutes.
- Your blood tests for heart strain (NT-proBNP) are above certain levels.
- You have not had a heart attack, stroke, or certain heart procedures in the last 3 months.
- Your heart rhythm is stable and you do not have serious arrhythmias or a pacemaker you use regularly.
- You do not have severe lung disease, diaphragm paralysis, or other major health issues.

This trial tests a device that helps stimulate the diaphragm to improve breathing in patients who need a ventilator. It's for people with new breathing problems who have been in the ICU on a ventilator for less than 4 days.
This study tests whether using two implanted devices (CardioMems and BaroStim) can improve heart function and symptoms in people with advanced heart failure. It aims to help patients who are already on standard medications get even better results.
This trial tests a procedure called pulmonary artery denervation (using a catheter to treat nerves in the lung's blood vessels) for people with heart failure who still have a preserved ejection fraction (their heart squeezes normally but doesn't fill properly). The procedure aims to reduce pressure in the lungs and improve symptoms like shortness of breath. Participants must be on stable heart failure medications and have elevated BNP levels, among other requirements.
This trial tests whether a special pacing pattern can strengthen your heart's pumping ability. You may qualify if you have heart failure with a low ejection fraction and already have a pacemaker or defibrillator with an atrial lead.
This trial is testing a new way to pace the diaphragm using a special vein in your chest, done at the same time as a standard CRT device implant for heart failure. It aims to see if this approach is safe and works well for helping you breathe.
This study tests whether a CardioPulmonary Management (CPM) system device used at home is safe and can improve outcomes for people with chronic heart failure. It may help manage symptoms and reduce complications, especially for higher-risk patients.
