Testing a smartwatch to record heart rhythms
This study is testing whether a connected watch (like a smartwatch) can accurately record your heart's electrical activity (an ECG) during a hospital stay or clinic visit. If it works well, it could make checking your heart easier and more convenient.
PessacAges Any age - NCT06272578Recruiting
Heart and kidney health study for chronic disease patients
This study checks how heart and kidney health are related in people with kidney disease, diabetes, high blood pressure, or high cholesterol. It is a single visit with tests to see if certain heart problems are common in these conditions.
Wedding, State of BerlinAges 18 years+ - NCT06273293Recruiting
Post-stent blood flow test with nitroglycerin for multivessel patients
This study tests a new way to measure blood flow after placing a stent, using a very thin wire with a camera. It helps doctors decide if the stent is working well without needing extra medication like adenosine—just a tiny dose of nitroglycerin. You may qualify if you have blockages in two or more heart arteries and are already scheduled for a stent procedure.
AlicanteAges 18 years+ - NCT06273475Recruiting
Robot-assisted training vs standard training for stroke recovery

Medication management service for diabetes and high blood pressure
This study tests a medication management service for people with type 2 diabetes and/or high blood pressure who take many medications. It aims to help you better manage your medicines and avoid urgent medical visits.
Hong KongAges 18 years+ - NCT06274697Recruiting
Testing a magnetic sensor for artery blood flow
This study tests a new magnetic sensor that measures blood flow in your arteries, comparing it to the standard method. It takes place in the heart-lung unit at Montpellier University Hospital, and aims to see if the sensor is accurate for people with or without leg artery disease.

Prevention program for heart and artery disease
This study tests a prevention program for people who have already had a heart event, stroke, or leg artery blockage. It is designed to help reduce the risk of future heart problems.
Canicattì, AGAges 18 years+ - NCT06275386Recruiting
Drug-coated balloon for chronic heart artery blockages
This trial tests whether a special balloon coated with medicine (drug-coated balloon) can safely open a completely blocked heart artery, instead of using a permanent stent. It may be an option for people who have chronic chest pain or shortness of breath due to a long-standing blockage.
Warsaw, Masovian VoivodeshipAges 18 years+ - NCT06275399Recruiting
Study of plaque and platelets in narrowed heart arteries
This study looks at how plaque buildup and blood platelets interact in partially blocked heart arteries. It might help find better ways to treat people with chronic coronary syndrome.
Warsaw, Masovian VoivodeshipAges 18 years+ - NCT06275503Recruiting
Stroke Prevention Through Improved AFib Screening
This study tests a new way to find hidden atrial fibrillation (an irregular heartbeat) in people aged 75-76 in the Värmland region. If caught early, treatment can help prevent strokes.
StockholmAges 75–76 - NCT06275516Recruiting
Virtual Reality with Sights, Sounds, and Touch for Stroke Recovery
This study tests whether a special virtual reality program that uses sights, sounds, and touch can help people who have had a stroke move their leg better. You might qualify if you had a first stroke, have trouble moving your leg, and can walk a little bit with help.
Chongqing, Chongqing MunicipalityAges 18–85 - NCT06276374Recruiting
Dual antiplatelet therapy after carotid artery stenting for high bleeding risk
This trial tests if taking two blood thinners (dual antiplatelet therapy) after a carotid artery stenting procedure is safe and effective for patients who have a higher risk of bleeding. It focuses on people with significant blockages in the neck arteries who are also at increased risk for serious bleeding or brain bleeds.
SeoulAges 19 years+ - NCT06277362Recruiting
New Leg-Saving Treatment for Critical Limb Ischemia
This study tests a new way to restore blood flow to the leg in people who have wounds or dead tissue on their foot and have run out of other treatment options. It's for those who have already tried angioplasty twice without success or have severely hardened small arteries.
Ancona, AnconaAges 18 years+ - NCT06277297Recruiting
Heart MRI study for Takotsubo syndrome patients
This study uses MRI to learn more about Takotsubo syndrome (a temporary heart condition often triggered by stress). If you have been diagnosed with Takotsubo and have had certain heart tests, you may be able to join.
Cagliari, ItalyAges 18 years+ - NCT06278259Recruiting

Cairo, DokkiAges 65–75 - NCT06277427Recruiting
CAR-T cell therapy for refractory vasculitis and lupus nephritis
This trial tests a new type of cell therapy called CAR-T cells that target BCMA (a protein on certain immune cells) for people with two autoimmune diseases: ANCA-associated vasculitis and lupus nephritis. It is for patients whose disease has not responded to standard treatments or has come back after initial improvement.
Wuhan, HubeiAges 18–70 - NCT06278844Recruiting
