SingaporeAges 21–79 - NCT06756009Recruiting
Eye scans to check liver disease and transplant outlook
This study uses advanced eye scans to see if your eyes can give clues about your chronic liver disease and how well you might do after a liver transplant. If you have advanced liver disease or cirrhosis, and are maybe waiting for a transplant, you may join.
Guangzhou, GuangdongAges 18 years+ - NCT04843371Recruiting
Using wearable data to predict heart pump strength
This trial tests whether a wearable device (Biostrap) can help predict how strongly your heart pumps, using echocardiogram (heart ultrasound) results. It may help doctors better estimate heart function from simpler measurements.
New Orleans, LouisianaAges 18–120 - NCT04895995Recruiting
Digital CBT program for anxiety after heart or stroke events
This trial tests a scalable online “CBT” program (a structured talking-therapy approach) to reduce generalized anxiety and related health behaviors in people after a recent heart or stroke problem. If you qualify, it may help you learn tools to manage anxiety and health routines in a convenient digital format.
Boston, MassachusettsAges 18 years+ - NCT05916287Recruiting
STANISLAS cohort follow-up visit for heart and kidney health
This study is a follow-up visit for people who joined the STANISLAS family health cohort. Researchers look at how genes and environment may affect heart and kidney (kidneys) health over time.
Vandœuvre-lès-Nancy, LorraineAges Any age - NCT06212479Recruiting
Whole-body MRI for Preventive Health Screening
This study uses whole-body MRI to see if it can find health issues early in people without symptoms. The goal is to learn if this scan can help predict clinically important conditions in routine preventive care.
Watertown, MassachusettsAges 18 years+ - NCT06476470Recruiting
Taiwan ILD registry for understanding lung disease

BariAges 25–85 - NCT06330480Enrolling by invitation
Screening for heart rhythm and kidney disease at home
This study is testing whether screening people at home can catch early signs of an irregular heartbeat (atrial fibrillation) and kidney disease. If you're in the right age group and live in one of the selected regions, you could join and help researchers learn more about spotting these conditions early.
AmsterdamAges 50–75 - NCT05951764Recruiting
Checking risk prediction for heart and brain conditions
This study builds or tests computer models that predict risk for heart (cardiovascular) and thinking/memory (neurocognitive) problems using information from people in the general population. It may help improve early detection and planning for care.
ParisAges 45 years+ - NCT07735403Recruiting
Contactless heart and breathing monitor test
This trial tests a device called Dozee that can check your heart rate and breathing without touching you. If you help, you will be monitored while resting in a bed or chair to see if the device works as well as standard monitors.
