Music during nursing care for stroke patients in the ICU
This trial studies if listening to music during a bed bath can improve comfort for stroke patients in the intensive care unit. It aims to make nursing care more relaxing and less stressful.
ParisAges 18 years+ - NCT07314138Recruiting
Comparing two minimally invasive heart bypass surgeries for three-vessel disease
This trial compares two types of heart bypass surgery for people with blockages in three main heart arteries. It tests a hybrid approach that combines a small incision bypass with a stent, versus a standard off-pump bypass. This may mean less recovery time for some patients.
Leuven, Vlaams BrabantAges 18–85 - NCT07315178Recruiting
Digital twin study for chronic aortic dissection
This study is creating a digital twin model to predict how chronic thoracic aortic dissection progresses. If you have a type A or type B aortic dissection, this study may help researchers better understand your condition without additional stress or invasive procedures.
DijonAges 18 years+ - NCT07307183Recruiting
Predicting foot ulcers risk in diabetes
This study is developing a tool to predict your risk of getting foot ulcers if you have diabetes. By analyzing medical records, the researchers hope to identify people who need extra prevention and care.
JonseredAges 18 years+ - NCT07309523Recruiting
Heart muscle strength in heart failure and diabetes
This study looks at how heart muscle strength changes in people with heart failure and/or diabetes. Researchers will use a pacemaker to safely measure tiny changes in heart function.
Leeds, West YorkshireAges 18 years+ - NCT07309497Recruiting
Geriatric Assessment for Older Adults Before CAR-T or Bispecific Therapy
This trial studies how a simple geriatric assessment (a check-up for older adults) can help predict side effects and outcomes in patients aged 65+ who are about to receive CAR-T cell therapy or bispecific antibody treatment.
BernAges 65 years+ - NCT07313657Recruiting
Heart health and well-being support study
This study tests a web tool designed to improve mental well-being for adults with heart failure. If you have heart disease or take certain heart medications, you may help shape better care for yourself and others.
Cornwall, OntarioAges 40 years+ - NCT07307989RecruitingPhase 2
Statin plus ezetimibe vs. statin alone after stroke
This trial compares two treatments for people who recently had a stroke or TIA and have high cholesterol with artery plaque. Some participants will get a combination of two cholesterol-lowering medicines (statin and ezetimibe), while others will get only a statin.
PoziAges 20–100 - NCT07311044Recruiting
Heart health and voice study at Mayo Clinic
This study at Mayo Clinic looks at how heart and lung blood pressure (cardiovascular/pulmonary hypertension) might relate to voice characteristics. Researchers will use voice recordings from people having routine echocardiograms to see if voice changes can help detect heart problems earlier.
Rochester, MinnesotaAges 18 years+ - NCT07310849Recruiting
Digital health support for older adults with diabetes
This study tests a digital care program using the LINE messaging app to help older adults with diabetes and other chronic conditions manage their health. It may be a good fit if you are 50 or older, have type 2 diabetes plus another condition like high blood pressure, and are comfortable using a smartphone.
New Taipei City, Wugu DistrictAges 50 years+ - NCT07309718Recruiting
Stroke Risk Assessment for Brain Artery Narrowing
This study looks at a new way to measure stroke risk in people with a specific type of brain artery narrowing (atherosclerosis) in the front part of the brain. You might participate if you have this condition and are willing to have imaging tests and take standard medicines.
Beijing, Xicheng DistrictAges 18–80 - NCT07312318Recruiting
AI predicts heart artery changes after stenting
This study uses artificial intelligence to predict how heart arteries might change after a stent procedure (PCI). Researchers will collect blood samples and medical data to develop a tool that could help doctors make better treatment decisions.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06829212Recruiting

Shanghai, Shanghai MunicipalityAges 18–80 - NCT02798731Recruiting
Testing blood vessel function after a heart transplant
This trial measures how well tiny blood vessels in the heart are working in people who have had a heart transplant. It may help doctors understand transplant-related circulation problems and guide future care.
SeoulAges 18–85 - NCT06874465Recruiting
Aortic valve replacement study for severe stenosis
