This study uses a virtual reality pathfinding game to see how your brain activates after a stroke. It may help doctors understand how to improve recovery.
Chongqing, Chongqing MunicipalityAges 18–80 - NCT06703307Recruiting
Brain markers for stroke-related thinking changes
This study uses a special brain scanning technique (fNIRS) to look for markers that show how stroke affects thinking. Both people who have had a stroke and healthy volunteers can join.
Chongqing, Chongqing MunicipalityAges 18–80 - NCT06704048Recruiting
Heart rehab after endocarditis: quality of life study
This study looks at how a heart rehabilitation program affects quality of life and personal experiences in people who have been treated for infective endocarditis (a serious heart infection). It aims to find out if this type of rehab helps patients feel better and recover more fully.
Halmstad, Halland CountyAges 18–90 - NCT06704230Recruiting
Video goggles to reduce stress during awake neck artery surgery
This trial tests if wearing video goggles during carotid artery surgery can help reduce stress. You would stay awake during the procedure and watch calming videos to see if it makes the experience less stressful.
Augsburg, BavariaAges 18 years+ - NCT06705023RecruitingPhase 2
Fat-derived cell therapy for heart failure
This study tests whether taking a small amount of your own belly fat (through liposuction), processing it, and injecting the cells back into your heart can improve heart function in people with chronic heart failure due to blocked arteries. The trial is for patients whose heart pumps weakly (ejection fraction of 40% or less) and who are already on standard medications.

Genetic study of complex heart defects in unborn babies
This study looks at the genetic material in the fluid around the baby (amniotic fluid) and in the placenta to better understand complex heart defects in unborn babies. The goal is to find new clues that could help doctors care for these babies before and after birth.
BordeauxAges 18 years+ - NCT06705751Recruiting
Faster diagnosis of abnormal coronary artery origin
This study tests a new, faster way to diagnose an uncommon heart condition where one of the main arteries (the coronary artery) starts from the wrong place on the aorta. The goal is to help doctors find and treat it sooner.
