Study of a new heart valve for aortic stenosis
This study is testing a new type of heart valve (Navitor or Navitor Vision) for people with aortic stenosis. The valve is placed without open-heart surgery, and the goal is to see how well it works in a real-world setting. If you've already been recommended for this procedure by your heart team, you may be able to join.
San Donato Milanese, LombardyAges 18 years+ - NCT07353775Recruiting
Heart procedure using imaging and pulsed energy
This trial uses a special imaging tool inside the heart to guide a new type of energy (pulsed field) to treat a specific area in the heart that can cause atrial fibrillation (an irregular heartbeat). It may help people with paroxysmal or persistent atrial fibrillation who need a procedure called CTI ablation.
BeijingAges 18 years+ - NCT07356687Recruiting
Transcranial magnetic stimulation with walking training for stroke recovery
This trial studies whether combining brain stimulation (rTMS) with walking and thinking exercises helps improve walking and memory after a stroke. It is for people who had a stroke at least 6 months ago and can walk on their own for at least 1 minute.
Hong Kong, HongKongAges 50 years+ - NCT07353905Recruiting
Ultrasound guidance for leg artery treatment
This trial tests whether using a special ultrasound probe inside the artery (intravascular ultrasound) helps doctors better treat blocked leg arteries. It may lead to more effective procedures for patients with leg pain or wounds due to poor blood flow.
Dallas, TexasAges 18 years+ - NCT07355192Recruiting
Group singing for heart health
This study tests whether singing in a group can improve heart health in people with a history of coronary artery disease. If you join, you'll sing with others and see if it helps your heart function.
Milwaukee, WisconsinAges 55–89 - NCT06849505Recruiting
Brain stimulation with movement training for stroke recovery
This trial tests if combining transcranial magnetic stimulation (TMS) with arm and hand exercises helps people recover upper limb function after a first stroke. It is for adults who can follow instructions and have no metal in their head or a pacemaker.
Shanghai, Shanghai MunicipalityAges 20–80 - NCT06010563Recruiting
Study of a new heart valve for severe pulmonary valve leakage
This study tests a new less-invasive heart valve (VenusP-Valve) for people whose own pulmonary valve is leaking severely. If you qualify, you could get the new valve without open-heart surgery.
Irvine, CaliforniaAges 12 years+ - NCT06633146Recruiting
Stroke rehab in nature settings
This trial tests if stroke recovery exercises in natural environments can help improve your rehabilitation. It is for people who have had a recent stroke.
LahtiAges 18 years+ - NCT06774014Recruiting
Heart failure and diabetes: cell study
This study looks at how cells talk to each other in people who have both diabetes and heart failure. It may help doctors understand these conditions better.
Leeds, West YorkshireAges 18 years+ - NCT06852079RecruitingPhase 3
Testing a herbal pill for mild to moderate high blood pressure
This study tests if a traditional herbal pill called Qurs e Fishar can safely lower blood pressure in adults with mild to moderate hypertension. It may be an option for people looking for natural treatments.
Karachi, SindhAges 30–60 - NCT05134246Recruiting
Stent or procedure for narrowed carotid artery after neck radiation
This trial studies a carotid artery procedure (revascularization) to treat a major narrowing in the neck artery that happened after you had radiation for head or neck cancer. It may help prevent stroke risk by improving blood flow to the brain.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06851949RecruitingPhase 2
Vsling device for ventricular repair in heart failure
This trial tests a new device called Vsling, which is placed inside the heart to help reshape the main pumping chamber (left ventricle) in people with heart failure. It may improve your heart's strength and reduce symptoms like shortness of breath.
Be’er Ya‘aqovAges 18 years+ - NCT04119791Recruiting
Study whether wild rice improves heart health
This study looks at whether eating wild rice can improve cardiovascular (heart and blood vessel) health. It is testing this in generally healthy adults who fit specific health and lifestyle criteria.
Winnipeg, ManitobaAges 20–40 - NCT06162247Recruiting
Registry study for heart patients in intensive care
This study tracks patients with sudden heart problems admitted to a special heart intensive care unit. It helps doctors learn more about these conditions to improve future care.
NaplesAges 18 years+ - NCT06381427Recruiting
Improving care for older heart patients before surgery
This trial studies whether special care planning before non-cardiac surgery can improve outcomes for older adults with signs of heart stress. If you are 65 or older and scheduled for a moderate- to high-risk surgery, you may be able to join.
GiessenAges 65 years+ - NCT06707220Recruiting
Türkiye heart failure registry
This trial is a heart failure registry that collects information from people with heart failure across Turkey. By joining, researchers can learn more about the condition and how to treat it better.
Ankara, AnkaraAges 18 years+ - NCT06718179RecruitingPhase 4
Short vs. 12-month prasugrel and aspirin after a heart attack with a stent
This trial compares taking a shorter course of prasugrel (a blood thinner) plus aspirin after a heart attack versus the standard 12-month course. It aims to see if a shorter duration is just as effective and safer for people who got a specific type of stent (everolimus-eluting).
AalborgAges 18 years+ - NCT06854978Recruiting
Video game arm rehab at home for stroke recovery
This study tests a home-based video game program designed to help people with stroke improve arm and hand movement. If you have some movement in your affected arm and can use a computer, this trial may help you regain function through engaging, game-like exercises.
West Orange, New JerseyAges 20–80 - NCT06853951RecruitingPhase 3
