Adding abdominal CT to standard lung cancer screening
This study adds an optional CT scan of the belly to the usual lung cancer screening in certain areas of England. It aims to see if this extra scan helps find more health issues early.
HullAges 55–70 - NCT07171242Recruiting
Stroke patient registry study
This study is a registry that collects information from people who have had an ischemic stroke (a type of stroke caused by a blocked blood vessel in the brain). By tracking this information, researchers hope to better understand the condition and improve care for future patients.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07171463Recruiting
New ablation for paroxysmal atrial fibrillation
This trial tests a new treatment that uses two types of energy (pulsed field and radiofrequency) to fix the heart's electrical signals in people with paroxysmal atrial fibrillation (AFib that comes and goes). It aims to be more effective and safer than standard ablation alone.
Rzeszów, Podkarpackie VoivodeshipAges 18 years+ - NCT07171905RecruitingPhase 2
Study of a new imaging agent for Von Hippel-Lindau disease
This trial tests a special imaging agent that targets a protein found in tumors related to Von Hippel-Lindau (VHL) disease. It may help doctors better detect and monitor these tumors.
Milan, ItaliaAges 18 years+ - NCT07172477Recruiting
Early study of the Pivot Extend system for leaky tricuspid valve
This trial tests a new device (Pivot Extend) to fix a severe leak in your tricuspid heart valve. It is for people who still have symptoms like shortness of breath or fatigue despite taking medicine.
Macquarie Park, New South WalesAges 18 years+ - NCT07172464Recruiting
Study of a new device to close a hole in the heart after a stroke
This trial tests a new device to close a PFO (a small hole between the upper chambers of the heart) in people who have had a stroke caused by a blood clot. The goal is to prevent future strokes by blocking the hole.
Los Angeles, CaliforniaAges 18–65 - NCT07172789Recruiting
Head down position before clot removal for large stroke
This trial tests whether a specific head-down position before a clot removal procedure improves outcomes for people with a large vessel occlusion stroke. It is for patients who have a confirmed blockage and can wait a short time before the procedure.
Shenyang, None SelectedAges 18 years+ - NCT07172893RecruitingPhase 4
Dermabind TL for diabetic foot ulcers
This trial tests a new wound dressing called DermaBind TL for people with diabetic foot ulcers. It aims to see if the dressing helps heal these wounds, which can be hard to treat.
DeLand, FloridaAges 18–80 - NCT07173062Recruiting
Algae supplement for heart health and gut bacteria
This study tests whether a supplement made from algae can help improve markers of heart health and affect the bacteria in your gut. It is for people age 50 and older who already have a condition like heart disease, kidney disease, or diabetes.
PortoAges 50 years+ - NCT07173426Recruiting
Using bioimpedance to guide fluid therapy in heart failure
This study tests a new way to manage fluid buildup in patients hospitalized with worsening heart failure. It uses a simple, non-invasive tool (‘bioimpedance’) to help doctors better balance your fluids, which could help you feel better and recover faster.
Basildon, EssexAges 18 years+ - NCT07173855RecruitingPhase 4
Magnesium replacement in ICU patients
This trial tests whether giving magnesium as part of a standard hospital protocol can lower the risk of irregular heartbeat and improve survival in patients admitted to the intensive care unit.
Ajax, OntarioAges 16 years+ - NCT07174206Recruiting
Smartwatch monitoring for heart patients
This trial tests a smartwatch tool to track heart rhythm and detect problems in people with heart disease. It may help find irregular heartbeats early during routine checkups.
São Paulo, São PauloAges 22 years+ - NCT07174362Recruiting
Heart failure study for newly diagnosed patients
This study is tracking people who were recently diagnosed with heart failure and have a weakened heart pumping function (less than 50%). It aims to learn more about the condition and improve care.
Basildon, EssexAges 18 years+ - NCT07174505Recruiting
Study of the CONDA Stent Retriever for stroke patients
This trial tests a device called the CONDA Stent Retriever to remove blood clots in people having a severe stroke caused by a blockage in a large brain artery. It may help if you can be treated within 24 hours of symptoms starting and meet specific brain scan and health criteria.
BudapestAges 18–85 - NCT07174622Recruiting
Long-term results for renal denervation study
This study tracks patients who have uncontrolled high blood pressure and are on a steady medication plan. It checks how kidney nerve treatment (renal denervation) works in real life over time.
Boston, MassachusettsAges 18 years+ - NCT07174986RecruitingPhase 2/Phase 3
Double defibrillation for out-of-hospital cardiac arrest
This trial tests whether giving two shocks in a row (instead of one) helps restart the heart in people who have a cardiac arrest outside the hospital and need a defibrillator.
AmsterdamAges 18 years+ - NCT07175519Recruiting
Safety of devices used to treat aneurysms
This study looks at how safe and effective different devices are when used to repair aneurysms through a minimally invasive procedure called endovascular treatment. It may help doctors choose the best treatment for you.
LondonAges Any age - NCT07175532Recruiting
Registry for mitral stenosis balloon treatment
This study tracks patients with a heart valve condition called mitral stenosis who are getting a procedure called percutaneous mitral balloon commissurotomy, or PMBC. It aims to see how well the procedure helps improve their symptoms and health over time.
SeoulAges 18–89 - NCT07176260Recruiting
Blood cell function and stress in pulmonary hypertension
This study looks at how blood cells work and handle stress in people with certain types of pulmonary hypertension. By understanding these processes, doctors hope to improve diagnosis and treatment.
Strasbourg, Bas-RhinAges 18 years+ - NCT07176507Recruiting
Study of multiple and mixed heart valve disease
