Iron supplements and the immune system in HHT
This study looks at how iron supplements affect the immune system in people with HHT (a genetic condition that causes bleeding from abnormal blood vessels). You may be placed in one of three groups depending on your iron and ferritin levels.
Bron, RhoneAges 18–99 - NCT07111884Recruiting

BerlinAges 18 years+ - NCT07112183RecruitingPhase 4
Treprostinil study for Raynaud's attacks
This trial tests a medication called treprostinil to see if it can help people who have frequent Raynaud's attacks. It is for patients with primary or secondary Raynaud's (related to conditions like scleroderma or lupus) who still have attacks despite current treatments.
Boston, MassachusettsAges 18 years+ - NCT07112391Recruiting
Pressure volume loop study for valve disease
This trial uses a special heart test called pressure volume loop assessment to better understand how well your heart pumps when you have severe valve disease. It aims to find patterns that may help doctors treat you more effectively. You may join if you have certain types of severe heart valve problems.
Nantes, Loire AtlantiqueAges 18 years+ - NCT07112820Recruiting
Heart imaging test for chest pain without ST elevation
This trial tests if a heart imaging scan (myocardial perfusion) can help doctors better diagnose heart attacks or other conditions in people who come to the hospital with chest pain but without ST elevation on their ECG. It aims to see if the scan adds valuable information before heart catheterization.
Paris, Ilede FranceAges 18 years+ - NCT07112911Recruiting
Electrical stimulation with robot for arm recovery after stroke
This trial tests if combining two types of electrical stimulation with a robotic device can help improve arm movement in people who had a stroke at least 6 months ago. It may be a good option if you have some movement in your arm but not full strength.
Hong KongAges 25–70 - NCT07112924Recruiting
CCM Heart Device Registry Study
This registry study follows patients who have or will get a CCM device to see how well it works and how safe it is over time. It helps doctors learn more about improving heart function in people with heart failure.
Mesa, ArizonaAges 18 years+ - NCT07113067RecruitingPhase 1/Phase 2
Accelerated rTMS for Stroke Apathy
This study tests a non-invasive brain stimulation treatment called rTMS to see if it can help reduce apathy (lack of motivation) after a stroke. You would receive either real rTMS or a sham (fake) treatment over several sessions.
Charleston, South CarolinaAges 40 years+ - NCT07113041Recruiting
Brain stimulation and robot balance training after stroke
This study tests if adding a gentle brain stimulation (TMS) to robot-assisted balance training helps improve balance after a stroke. It is for people who had a stroke at least 6 months ago and still have trouble with balance.
West Orange, New JerseyAges 18–75 - NCT07113769Recruiting
Biomarkers and platelets in CPR patients
This trial is studying the blood biomarkers and platelet characteristics in patients who receive CPR and are then placed on a heart-lung bypass machine (ECPR). It aims to understand how these biological markers relate to patient outcomes.
Zhengzhou, HenanAges 18 years+ - NCT07113990Recruiting
Electroacupuncture and brain stimulation for stroke recovery
This trial tests whether combining two therapies—electroacupuncture (needles with mild electric current) and rTMS (a magnetic pulse to the brain)—can help you regain movement after a stroke. It is designed for people who had their first stroke less than 6 months ago and are still working on motor recovery.
Fuzhou, FujianAges 40–75 - NCT07114393Recruiting
Better imaging to guide complex heart artery procedures
This study looks at whether using advanced imaging inside the heart arteries during complex procedures leads to better outcomes compared to current standard practice. If you have had a complex angioplasty (PCI) and your data is in a national heart registry, you may be included.
Eindhoven, North BrabantAges 18 years+ - NCT07114510Recruiting
Best breathing methods during cardiac arrest
This trial compares different ways to give breaths using a breathing tube during CPR to find the best approach for people having a cardiac arrest in the hospital.
Orange, CaliforniaAges 9 months–18 years - NCT07115108Recruiting

This study tests a special high-energy formula for babies with congenital heart disease who are at nutritional risk. It aims to see if this feeding helps them grow and develop better before and after heart surgery.
Shanghai, Shanghai MunicipalityAges birth–6 months - NCT07115511Recruiting
Surgical rescue after failed clot removal for stroke
This trial tests a surgical rescue treatment for people who have had a major stroke from a large artery blockage, but the standard clot removal procedure (thrombectomy) did not fully open the artery. The goal is to see if combining surgery with the earlier procedure can improve outcomes.
Tianjin, Tianjin MunicipalityAges 18–75 - NCT07116083Recruiting
Study of a new way to check branch blockages after stent placement
This trial looks at a new method called µQFR to check if there are any significant blockages in the side branches of heart arteries after a single stent has been placed. It aims to see if this method can help doctors decide if more treatment is needed.
