Hybrid or catheter ablation for atrial fibrillation in hypertrophic heart
This trial compares two procedures to treat atrial fibrillation (an irregular heartbeat) in people who also have hypertrophic cardiomyopathy (thickened heart muscle). It looks at whether the hybrid approach or a catheter-based approach works better for controlling symptoms and heart rhythm.
BeijingAges 18 years+ - NCT06560047Recruiting
Early catheter ablation for atrial fibrillation with heart failure
This trial tests whether early catheter ablation (a procedure to fix irregular heartbeats) helps people who have both heart failure and atrial fibrillation. It looks at how this treatment affects your heart function and quality of life.
AalborgAges 18–80 - NCT07758894Recruiting
Breathing without a breathing tube during heart transplant surgery
This study tests whether heart transplant surgery can be done while the patient is awake and breathing on their own, instead of using a breathing tube. If successful, it may lead to faster recovery and fewer complications.
Guangzhou, GuangdongAges 18 years+ - NCT07764510Enrolling by invitation
Heart-to-heart support for teens with congenital heart disease
This study tests a support program designed to help teens with congenital heart disease feel better and manage their health. It may improve emotional well-being and heart health.
Columbus, OhioAges 12–18 - NCT07764094Recruiting
Balloon treatment for blocked heart arteries
This trial tests how the way a drug-coated balloon is used during a heart procedure affects outcomes for people with stable heart disease or unstable angina. It may help doctors find the best technique to keep arteries open.
Chuzhou, AnhuiAges 18–80 - NCT07758582Recruiting
Artificial intelligence for detecting diabetic retinopathy from eye photos
This study tests an AI system that automatically detects signs of diabetic retinopathy from eye photos. It aims to see if the AI can accurately identify these signs to help with early detection.
AlexandroupoliAges 18 years+ - NCT07759791Recruiting
Life coaching after stroke to rejoin valued activities
This trial tests a coaching program that helps people who have had a stroke get back into activities they value, like hobbies or social outings. It may help you feel more connected and improve your quality of life.
Kingston, OntarioAges 18 years+ - NCT07764588Recruiting
Immune cell study after a heart attack
This study looks at how immune cells change in the first few hours after a severe heart attack (STEMI) and how that relates to early scar healing. It may help doctors understand why some patients heal better than others.
ShanghaiAges 18–80 - NCT07763340Recruiting
Photon-counting ct heart scan for people with coronary stents
This study tests a new type of CT scan that takes very detailed pictures of the heart and stents. It may help doctors see whether stents remain open and guide future care.
Beijing, Beijing MunicipalityAges 18–100 - NCT07761910RecruitingPhase 2
Study of heart effects of radiation therapy using PET-CT for stage III lung cancer
This study looks at whether PET-CT scans can help detect heart damage caused by radiation therapy in patients with stage III lung cancer. If you're getting chemotherapy and radiation together, you may participate to help doctors find ways to reduce heart risks.
Indianapolis, IndianaAges 18 years+ - NCT07762677Recruiting
CT scan using new technology to check head vein stents
This study tests a new type of CT scanner that gives clearer pictures of the stent in the vein in your head after it has been placed. The goal is to see if this new scanner helps doctors see the stent better and spot any problems more easily.
Beijing, Beijing MunicipalityAges 18–90 - NCT07761728Enrolling by invitation
Comparing two heart PET scan tracers
This study compares two types of radioactive tracers used during heart PET scans to see if one is better at detecting blocked arteries. Participation involves receiving one of the tracers during your routine scan and may help improve heart disease diagnosis.
Los Angeles, CaliforniaAges 18 years+ - NCT07759635Recruiting
Effects of Plan B on heart health in young women
This study looks at how the emergency contraceptive Plan B (levonorgestrel) affects heart and blood vessel health in young, naturally cycling women. Participants will take the medication and have their cardiovascular health measured over a short period.
Hamilton, OntarioAges 18–35 - NCT07766135Recruiting
Liver and blood clotting in heart amyloidosis
This study looks at how the liver and blood clotting are affected in people with a type of heart disease called transthyretin amyloidosis. It may help doctors better understand and manage this condition.
Messina, SicilyAges 18 years+ - NCT07762664Recruiting
Photon-counting CT versus regular CT for evaluating carotid artery narrowing before stenting
This study compares two types of CT scans to evaluate the arteries in your neck before you have a stent placed. The newer photon-counting CT may provide more detailed images, which could help your doctor plan the procedure more precisely.
Beijing, Beijing MunicipalityAges 10–90 - NCT07764900Recruiting
Embolization for varicocele
This study tests a minimally invasive procedure to treat varicocele, which is an enlargement of veins in the scrotum that can cause pain or affect fertility. The procedure blocks the abnormal veins to improve symptoms and potentially fertility.
