Eye disease health data study in Germany
This study looks at health records in Germany to understand how many people have certain eye conditions like age-related macular degeneration, diabetic macular edema, or retinal vein occlusion. It also tests new ways to use this information for research.
LeverkusenAges 18 years+ - NCT07308704Recruiting
Using AI to spot heart muscle disease on echocardiograms
This study at Mayo Clinic is testing an artificial intelligence (AI) tool that analyzes echocardiograms (ultrasound of the heart) to find early signs of four types of heart muscle disease. If the AI flags a high-risk pattern, doctors can learn whether acting on that alert helps catch the condition sooner.
Rochester, MinnesotaAges 18 years+ - NCT07309029Recruiting
ECMO support during high-risk TAVR heart valve procedure
This trial tests whether placing patients on ECMO (a heart-lung support machine) before a high-risk TAVR valve replacement can improve safety and outcomes. It is for people who are at very high risk due to low blood pressure, severe heart or lung problems, or complex valve anatomy.
Detroit, MichiganAges 18–100 - 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+ - 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+ - 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 - NCT07310693Recruiting
Validating a score to find hidden cancer in blood clot patients
This study tests how well a scoring system (CLOVER) can detect undiagnosed cancer in people who have had a blood clot (deep vein thrombosis or pulmonary embolism). Researchers want to see if the score can predict hidden cancer, which may lead to earlier treatment.
Barcelona, BarcelonaAges 18 years+ - 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+ - NCT07311135Recruiting
Smartwatch Oxygen Accuracy in Pulmonary Hypertension
This study tests how well a smartwatch measures oxygen levels in people with pulmonary hypertension during a 6-minute walk. It could help find a simpler way to check oxygen at home.
GlasgowAges 18 years+ - NCT07311343RecruitingPhase 4
Mouth care and antibiotics to prevent pneumonia after brain bleed
This trial tests whether a special mouth rinse and preventive antibiotics can lower the risk of pneumonia after a brain bleed (intracerebral hemorrhage). If you've had a small bleed in the upper part of the brain and are at risk for pneumonia, this study may help.
Beijing, Beijing MunicipalityAges 18–80 - NCT07312188RecruitingPhase 2
F182112 for relapsed or refractory multiple myeloma
This trial tests a new drug, F182112, for people whose multiple myeloma came back or didn't respond to prior treatments that included lenalidomide and a proteasome inhibitor. It may help if your disease has active signs like high protein levels.
TianjinAges 18 years+ - 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+ - NCT07313163Recruiting
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+ - NCT07313410Recruiting
Near-infrared light study for better understanding of PAD
This study uses near-infrared light to learn more about peripheral artery disease (PAD) in adults. It aims to help doctors better understand how PAD affects the body.
Arlington, TexasAges 18 years+ - NCT07313475Recruiting
Testing a new tool to detect lupus anticoagulant
This trial checks if a new method (Cryocheck HexLA Integrated TCA) can accurately find lupus anticoagulant in blood samples. Your leftover blood from regular tests may be used, and it requires no extra visits.
StrasbourgAges 18 years+ - NCT07313501Recruiting

A study of a liquid gel for brain AVM treatment
This trial tests a liquid embolic agent (a gel-like material) injected into the blood vessels of a brain arteriovenous malformation (AVM) to block abnormal blood flow. It’s for people aged 18 to 80 with certain types of AVMs that doctors think can be treated this way.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT07314008Recruiting
Comparing pacing methods for slow heartbeat with long AV delay
This trial tests two types of heart pacing to see which works better for people with a slow heartbeat from sinus node issues and a long delay between the upper and lower heart chambers (PR interval over 200 ms). The goal is to find the best way to pace the heart while keeping unnecessary pacing minimal.
