Recruiting studies
- NCT05723679Recruiting
Breathing-targeted program to improve function in HFpEF
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.
Dallas, TexasAges 55–90 - NCT05685303Recruiting
Testing a treatment for heart failure symptoms with normal pumping ability
This study is looking at a new treatment for people with heart failure where the heart’s pumping strength is not reduced much (HFpEF or HFmrEF), but pressure inside the heart is high during exercise. It may help relieve symptoms in people who still feel unwell during normal activity despite stable standard treatment.
Phoenix, ArizonaAges 40 years+ - NCT05700617RecruitingEarly Phase 1
Testing cardiac pumping strength in cardiogenic shock
This early study looks at how well the heart is pumping in people with cardiogenic shock, using measurements taken during a right-heart catheter (a small pressure-monitoring test). It may help doctors better assess heart function and guide next-step treatments like LVAD, heart transplant, or valve surgery.
Chicago, IllinoisAges 18 years+ - NCT05650307Recruiting
Heart and metabolic scan study of weight and rehabilitation
This study uses detailed heart scans and information about metabolism (how your body uses energy) to understand how metabolic treatments and heart rehabilitation may affect your health. You may qualify either as someone undergoing bariatric (weight-loss) care or as part of a heart rehabilitation group—or as a healthy comparison group.
Cleveland, OhioAges 18 years+ - NCT05672836RecruitingPhase 4
Enavogliflozin after TAVR for heart narrowing with mild heart weakness
This trial tests enavogliflozin (a diabetes medication that may help the heart) in people who have had a TAVR procedure for severe aortic stenosis. It looks at whether the medicine can improve outcomes for people with symptoms and mildly reduced or preserved pumping function.
Bucheon-siAges 19 years+ - NCT05604430Enrolling by invitation
Study of pre-hospital breathing support with a specific ventilator
This study looks at breathing support given outside the hospital using a particular ZOLL ventilator model and software version. If you were treated with the right equipment, the team will use the ventilator’s recorded data to evaluate how ventilation was delivered.
Hartford, ConnecticutAges Any age - NCT05628779Enrolling by invitation
Clip procedure to repair a leaking tricuspid valve
This trial studies a minimally invasive “edge-to-edge” clip procedure to reduce severe leakage of the tricuspid valve. It’s for people who still feel unwell despite standard treatments and may be too high-risk for open-heart surgery.
AmsterdamAges 18 years+ - NCT05585411Recruiting
Pacemaker type test to reduce heart worsening and death risk
This study compares two pacemaker pacing strategies—left-sided “bundle branch area” pacing versus right-sided ventricular pacing. It aims to see which approach better prevents heart failure getting worse and reduces abnormal timing between heart chambers over time.
Bucheon-siAges 19 years+ - NCT05548413Recruiting
Helping heart failure patients take meds with family support
This study tests whether family-focused coaching and easy-to-read materials can improve heart failure medication adherence. It also uses an electronic pillbox to track how consistently you take your meds, with your care partner involved.
Lexington, KentuckyAges 18 years+ - NCT05427370Recruiting
Compare bypass or stent treatment in weak heart patients
This study compares two ways to restore blood flow to the heart—bypass surgery (CABG) or stent procedure (PCI)—in people with a weak pumping heart. It looks at which approach works best when the heart muscle is not pumping well and there are multiple blocked heart arteries.
Los Angeles, CaliforniaAges 18 years+ - NCT05434819Recruiting
Ablation study during heart surgery for atrial fibrillation
This trial looks at whether a special heart rhythm treatment called “ablation” works well when done during certain heart operations. It may help reduce atrial fibrillation (AF) symptoms or future abnormal rhythm episodes for people who are already having surgery.
Hamilton, OntarioAges 18 years+ - NCT05388019Enrolling by invitation
VAD clinic visit study for new and returning patients
This trial looks at how well a specialized, multidisciplinary clinic works for people who have a ventricular assist device (VAD) and compares new VAD patients with those who have already had standard follow-up visits. It may help improve how care and check-ins are organized after your VAD is implanted.
Boston, MassachusettsAges 18 years+ - NCT05370014Recruiting
Partner support program for chronic health conditions
This study tests a program that helps patients with chronic health conditions and their care partners work together to improve their health and well-being. If you live in a rural or underserved area in South Carolina and have a condition like diabetes or high blood pressure, you and your support person might be able to join.
Columbia, South CarolinaAges 18 years+ - NCT05373940Recruiting
ICD placement to prevent sudden heart death in people over 70
This study looks at placing an ICD, a device that can stop dangerous heart rhythms, to help prevent sudden cardiac death. It is for people over 70 with specific heart function and heart failure symptoms.
Aix-en-ProvenceAges 70 years+ - NCT05376254Recruiting
3D heart scan study during LVAD implantation
This study uses special 3D heart imaging to better measure right-heart function during LVAD surgery. It may help doctors understand how the right side of the heart responds when a mechanical pump is put in.
Edmonton, AlbertaAges 16 years+ - NCT05279742Enrolling by invitationPhase 1/Phase 2
Study drug to boost a hormone system in HFpEF
This early-phase trial tests a treatment that aims to improve the “natriuretic peptide” hormone system in people with HFpEF (heart failure with preserved pumping strength). It may help reduce symptoms and improve heart and fluid pressure behavior, especially in certain related conditions like kidney disease.
Rochester, MinnesotaAges 18 years+ - NCT05230745Recruiting
Test device for heart failure safety and how well it works
This trial studies whether the ContraBand device can be safely placed in people with long-term, symptomatic heart failure and reduced heart pumping. It also looks at whether the approach is practical and tolerable, and gathers early safety information.
AalstAges 18–85 - NCT05230732Recruiting
