Heart ultrasound with contrast during exercise to study lungs
This study uses a special ultrasound (echocardiography) with a contrast dye to see how blood flows through your lungs during exercise. It aims to help doctors better understand why patients get short of breath during activity.

Exercise heart MRI in heart failure with preserved pumping strength
This study uses a special exercise MRI to see how the heart works during activity in people with a type of heart failure where the heart's pumping strength is normal. It also includes people with shortness of breath from other causes and healthy volunteers to compare results.
Rochester, MinnesotaAges 18–80 - NCT07175428RecruitingPhase 2
Safety of a New Blood Thinner in AFib Patients

Give cancer tissue samples to help future cancer research
This study collects tissue or other cancer-related samples to help researchers better understand cancer and develop better tests or treatments. You can join if you are being evaluated for or treated for cancer, and you agree to let your samples be used for research.
Sacramento, CaliforniaAges 2 months+ - NCT04545502Recruiting
Study of aortic grafts and heart patches after aortic surgery
This study looks at how well certain aortic grafts and cardiovascular patches work after surgery. It may help by improving care for people who need these devices, and by collecting safety and outcome information over time.
Aurora, ColoradoAges 18 years+ - NCT07410117RecruitingPhase 3
Preventing blood clots in advanced solid tumor cancer
This trial tests a new drug called REGN7508 to see if it can prevent dangerous blood clots in people with advanced or metastatic solid tumors. People with a higher risk of clots (based on a simple score or tumor genetics) may qualify.
Hialeah, FloridaAges 18 years+ - NCT05335928RecruitingPhase 3
Abatacept for immune-therapy heart inflammation in hospitalized adults
This Phase 3 trial tests abatacept to treat myocarditis (inflammation of the heart muscle) caused by immune checkpoint cancer medicines. It may help patients recover faster and safely manage this serious side effect while they are in the hospital.
Los Angeles, CaliforniaAges 18 years+ - NCT07251179Recruiting
Understanding immune cells in autoimmune diseases and immune deficiencies
This study looks at immune cells in people with certain autoimmune diseases or immune deficiencies. The goal is to understand how these cells work, which may help improve future treatments.
StrasbourgAges 18–70 - NCT05976685Recruiting
Close the left atrial appendage after stroke despite blood thinners
This study tests whether closing a heart pouch called the left atrial appendage can prevent future strokes in people with atrial fibrillation who had an ischemic stroke even while taking blood thinners. It may help reduce stroke risk by blocking a common place where clotting can start.
BrugesAges 18 years+ - NCT07769814Recruiting
Better CT imaging for brain stent checkups
This study looks at whether a new type of CT scanner can take clearer pictures of stents in the brain. The goal is to help doctors see if the stent is working well after it's been placed.
Beijing, Beijing MunicipalityAges 5–90 - NCT07772570Recruiting
Studying blood markers in coronary artery disease
This study collects blood samples and images from patients with heart muscle damage or those undergoing coronary angiography. The goal is to find new biomarkers that could improve diagnosis and treatment of coronary artery disease.
OxfordAges 18–90 - NCT07773272Recruiting
Combined heart, kidney, and metabolic care after a heart attack
This study tests a new approach to managing heart, kidney, and metabolic health together after a heart attack or unstable angina. It aims to improve your recovery and reduce future risks.
Heerlen, LimburgAges 18 years+ - NCT05714839RecruitingPhase 1/Phase 2
Belantamab for multiple myeloma
This study tests the safety and effectiveness of the drug belantamab, alone or with other treatments, for people with multiple myeloma that has come back or stopped responding to previous treatments.
Bullhead City, ArizonaAges 18 years+ - NCT07218887RecruitingPhase 1/Phase 2
Gene therapy for BAG3-related heart failure
This study tests an experimental gene therapy called ALXN2350 for people with dilated cardiomyopathy caused by a specific genetic change in the BAG3 gene. It aims to see if the therapy can improve heart function and slow disease progression.
Birmingham, AlabamaAges 18–70 - NCT07232030Recruiting
Barostim device for heart failure treatment
This trial tests a device called Barostim, which is implanted under the skin to stimulate nerves that help control heart failure. It's for people with mild to moderate heart failure whose symptoms are not fully controlled by medications.
Mobile, AlabamaAges 18 years+ - NCT02061436Recruiting
Chronic total occlusion procedure registry
This study collects data from patients who are having a procedure to open a completely blocked coronary artery. It may help improve future treatments for this condition.
Phoenix, ArizonaAges Any age - NCT07470788Recruiting
Vesalius TMVr system for leaky heart valve (mitral regurgitation)
This study tests a new device called the Vesalius TMVr system to fix a leaky mitral valve without open-heart surgery. It's for people with severe mitral regurgitation who are not good candidates for surgery.
VancouverAges 19 years+ - NCT07773870Recruiting
Cold weather exposure and heart healing after stent placement
This study looks at how living or working in cold regions affects heart recovery after a stent procedure. Participants will have heart imaging at the start and again 6 months later to see if cold exposure impacts heart function.
Beijing, Please Select An Option BelowAges 18–80 - NCT07207811RecruitingPhase 3
Coramitug for heart failure caused by ATTR amyloidosis
This trial tests a new medicine called Coramitug for people with heart failure due to ATTR amyloidosis, a condition where abnormal proteins build up in the heart. The study aims to see if Coramitug can improve heart function and quality of life.

Stroke clot-busting drug before transfer for artery clearing
This trial tests whether giving a clot-busting drug (tenecteplase) before transferring you to a hospital that can do a procedure to remove the clot improves outcomes for people who had a stroke up to 24 hours earlier. You may qualify if you have a blockage in a large artery in the front of your brain and can still get the procedure.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07772817Recruiting
Chest-strap heart monitor for active people

Free healthy groceries to help lower blood pressure
This study gives people with high blood pressure free healthy groceries for 4 weeks to see if eating better can lower their blood pressure. It might help you get your blood pressure into a healthier range.
Boston, MassachusettsAges 18 years+ - NCT07772518Recruiting
Comparing two guidance methods for pulsed field ablation in atrial fibrillation
This trial compares two ways of guiding a procedure to treat atrial fibrillation (an irregular heartbeat). One uses special sound waves to see inside the heart, and the other uses electrical mapping. Both are used with the FARAPULSE system to deliver a type of energy called pulsed fields to fixed areas of the heart.
