This trial tests a combined heart and brain rehabilitation program for young people with moderate to complex congenital heart disease. The goal is to improve both heart health and thinking skills, such as memory and attention.
BrusselsAges 8–25 - NCT05647213RecruitingPhase 1
Skin biopsy study of stem-cell therapy for congenital heart disease
This early study takes a small skin sample to make a personalized type of heart stem cells in the future. It is testing whether this approach is safe and feasible for people with complex single-chamber congenital heart disease and advanced heart failure.
Rochester, MinnesotaAges 18–40 - 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 - NCT05604131RecruitingPhase 2
Deferiprone after heart attack: a heart MRI study
This study tests if the drug deferiprone, given after a heart attack, can reduce heart damage. It uses heart MRI to see if the drug helps recovery.
Indianapolis, IndianaAges 18 years+ - NCT05593055RecruitingPhase 4
Test a heart and blood-pressure therapy in people with hypertension
This study looks at how mineralocorticoid-related hormone signaling affects small heart blood vessels and how efficiently the heart works in people with high blood pressure. It may help doctors understand which treatments could improve heart function in hypertension.
Boston, MassachusettsAges 18–75 - 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+ - NCT05573633Recruiting
Smartwatch test to detect irregular heartbeats after heart surgery
This study checks whether a smartwatch can spot an irregular heartbeat called atrial fibrillation soon after on-pump heart surgery. If the smartwatch works well, it could help clinicians find the problem earlier after surgery.
AmiensAges 18 years+ - NCT05585125RecruitingPhase 4
Testing an informed approach for older adults with HFpEF
This study looks at an “informed” approach to help manage HFpEF (a type of heart failure) in people age 65 and older. It checks whether a structured plan and monitoring are practical and safe for you over time.
New York, New YorkAges 65 years+ - NCT05568069Recruiting
Study of defibrillator implants for non-ischemic weak heart
This study looks at whether implantable defibrillators can reduce dangerous heart rhythms in people with non-ischemic cardiomyopathy (heart weakness not caused by blocked heart arteries), a heart scar, and very low pumping strength despite best treatment. It compares different approaches to choosing which patients should receive these devices.
High Wycombe, BuckinghamshireAges 18 years+ - NCT05560958Recruiting
Heart procedure study for specific BIOTRONIK EP products
This study collects real-world follow-up information after certain heart procedures that use specific BIOTRONIK equipment. It may help confirm how well these devices work in everyday care and improve future recommendations.
Bernau bei Berlin, BrandenburgAges 18 years+ - NCT04982419RecruitingPhase 2/Phase 3
Remote arm treatment to protect heart and kidneys in heart failure
This trial tests whether a simple “arm cuff” treatment done before a heart artery procedure can help protect the kidneys and the heart in people with congestive heart failure. If it works, it may lower the chance of kidney injury around the time of the scan/stent procedure.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT05510167Recruiting
How quitting alcohol affects heart rhythm after ablation
This study looks at whether stopping alcohol after a heart procedure called catheter ablation helps prevent irregular heartbeats from coming back and improves your thinking and quality of life.
Austin, TexasAges 18–85 - NCT05547607Recruiting
Study of heart valve infection signs on heart scans
This study looks at clinical symptoms and test findings to better understand heart valve infection (endocarditis) in adults. It may help doctors recognize the condition sooner and interpret echocardiography results more accurately.
Cona, FerraraAges 18 years+ - NCT05545176Recruiting
Testing rules for stopping resuscitation after out-of-hospital arrests
This trial studies and checks decision rules doctors can use to decide when to stop CPR in patients who have an out-of-hospital cardiac arrest. It may help make those decisions more consistent and safer across Asian countries.
TaipeiAges 18 years+ - NCT05493605Recruiting
MRI study of heart involvement in Wilson disease
This study looks at whether Wilson disease affects the heart, using MRI scans (and possibly contrast dye). Your results may help doctors better understand cardiac (heart) involvement and how it progresses in Wilson disease.
ParisAges 18 years+ - NCT05487612Recruiting
MiECC heart-lung machine vs standard bypass during heart surgery
This trial compares a newer heart-lung machine setup (MiECC) with the usual bypass technique during certain heart operations. It may help see whether MiECC changes outcomes like the need for blood transfusions or recovery after surgery.
TorontoAges 18–85 - NCT05423158Recruiting
Virtual coaching to help veterans attend cardiac rehab
This study tests if virtual coaching can help more veterans attend cardiac rehabilitation at home. It is for veterans with heart conditions who have been referred to home-based cardiac rehab.
San Francisco, CaliforniaAges 21 years+ - NCT05439031RecruitingPhase 2
Stereotactic radiation to reduce recurrent dangerous heart rhythm episodes
This Phase 2 study tests a precise form of radiation therapy to control recurrent ventricular tachycardia (VT), a dangerous fast heart rhythm. It may help people whose VT keeps coming back despite heart medicines and/or ablation, especially when ablation is not possible.
Amsterdam, North HollandAges 18 years+ - NCT05447559RecruitingPhase 4
Testing how long to give antibiotics after heart surgery
This study looks at how long patients should receive an antibiotic after certain types of heart surgery, to help prevent infections. It may help find the best “duration” of antibiotic prophylaxis after surgery through the breastbone (median sternotomy).
Dallas, TexasAges 18 years+ - NCT05450328RecruitingPhase 2
Breathing medicine to help heart-lung machine separation after surgery
This Phase 2 trial tests whether inhaled medicines (milrinone and epoprostenol) can make it easier to separate from the heart-lung machine during cardiac surgery. It may help reduce the risk of a difficult transition off the machine for the right patients.
Montreal, QuebecAges 18 years+ - NCT05443321Enrolling by invitation
Health information sharing during hospital transfers
This trial studies whether sharing patients’ health information between hospitals during transfers can improve outcomes. You may be included if you are moved from a specific partner hospital to Brigham and Women’s Hospital and admitted to certain hospital units.
Boston, MassachusettsAges 18 years+ - NCT05423665Recruiting
Ultrasound check to spot early growth problems in twin pregnancies
