This study uses a smartphone app to test how different beta blocker doses work best for you. It's for older adults with stable heart failure who want to fine-tune their treatment.
New York, New YorkAges 65 years+ - NCT07243119Enrolling by invitationPhase 4
Heart failure study with adenosine scans to predict recovery
This trial tests whether high-dose adenosine during a heart scan can better predict how well your heart muscle might recover, compared to standard dosing. The information could help doctors personalize treatment for people newly diagnosed with heart failure and a low ejection fraction.
HerningAges 18–100 - NCT07242326Enrolling by invitation
Blood Thinner Dose Check for Older Adults With AFib
This study looks at whether older adults with atrial fibrillation are taking the right dose of their blood thinner medicine. It aims to improve how doctors prescribe these medications in primary care.

TAVR outcomes for small aortic valves in Asian patients
This study looks at how well a minimally invasive heart valve replacement (TAVR) works for Asian patients with a small aortic valve opening. It aims to understand what affects the results.
Hong Kong, ShatinAges Any age - NCT07236398Enrolling by invitation
Modified left atrial maze procedure for atrial fibrillation
This trial tests a modified maze procedure to treat atrial fibrillation during heart surgery. It may help patients with AFib who are already scheduled for cardiac surgery.

Blood sugar levels in children with Long QT syndrome on beta-blockers
This study looks at how often low blood sugar (hypoglycemia) happens in young children with Long QT syndrome who take beta-blocker medicine. It may help doctors understand if these children need extra monitoring.
HelsinkiAges Up to 7 years - NCT07217366Enrolling by invitation
Speech-to-text tool for heart failure patients
This study tests a speech-to-text tool to help people with heart failure report their symptoms and health information more easily. It aims to see if using voice instead of typing can improve data collection.

Study of HuL001 for multiple myeloma that has come back or not responded
This trial tests a new drug called HuL001 combined with lenalidomide and dexamethasone for people with multiple myeloma that has returned or stopped responding to at least three prior treatments. It aims to see if this combination can help when other options have failed.
TaipeiAges 18 years+ - NCT07209527Enrolling by invitationEarly Phase 1
Truway diagnostic tools in primary care

Vision test study for macular eye disorders
This study uses a special vision test called microperimetry to track how well the macula (the center of the retina) works in people with certain eye conditions like geographic atrophy or diabetic eye disease. Healthy volunteers are also needed for comparison. The goal is to understand how these conditions affect retinal function over time.
