Study on heart function drugs for liver cirrhosis patients
This trial tests two heart medications, carvedilol and empagliflozin, to see if they improve heart function in people with cirrhosis (liver scarring). It might help those who have early signs of heart stiffness but normal pumping strength.
ChandigarhAges 18–65 - NCT07316855Recruiting
Iron-based covered stent for aortic narrowing
This trial tests a new type of stent made from iron that slowly dissolves in the body. It is designed to treat narrowing of the aorta (CoA) or narrowing that happens after CoA surgery. The goal is to see if the stent is safe and works well over one year.
Zhengzhou, HenanAges 1–60 - NCT07321964Recruiting
Digital yoga for quality of life with atrial fibrillation
This trial tests if a digital yoga program can improve quality of life, blood pressure, and heart rate in people with atrial fibrillation. It offers a convenient way to practice yoga from home using a smartphone or tablet.
HerlevAges Any age - NCT07317323Recruiting
Norwegian study on spontaneous coronary artery dissection
This trial is for people who have had a spontaneous coronary artery dissection (SCAD), a tear in a heart artery. It aims to learn more about this condition and how to treat it.
BergenAges 18 years+ - NCT07319039Recruiting
Brain scan study of breathlessness in cancer, COPD, and heart failure
This study uses a brain scan (fMRI) to learn how the brain processes shortness of breath in people with advanced heart failure, COPD, or lung cancer. It aims to help doctors better understand and treat breathlessness.
Geneva, Canton of GenevaAges 18 years+ - NCT07315997Recruiting
Heart health study for people with rheumatoid arthritis
This study looks at whether calcium in the heart arteries and a blood test (troponin) can help predict heart disease risk in people with rheumatoid arthritis. It may help doctors better prevent heart attacks and strokes.
Boston, MassachusettsAges 35–79 - NCT04750616RecruitingPhase 2
NAD+ for heart injury prevention around non-emergency surgery
This Phase 2 trial studies whether adding NAD+ can reduce heart muscle injury around scheduled heart surgery. It may help protect the heart (and possibly kidneys) in people considered higher risk for complications.
San Francisco, CaliforniaAges 18 years+ - NCT06586021Recruiting
Aortoseal device for sealing stent-grafts in belly aneurysms
This trial tests a new device called Aortoseal™ that is used during a stent-graft procedure to help secure the graft to the artery wall. It may improve the seal and help prevent the graft from slipping.
Norfolk, VirginiaAges 18 years+ - NCT06823570Recruiting
