Metabolic syndrome and recovery after colorectal cancer surgery
This trial studies how metabolic syndrome (a mix of high blood pressure, diabetes, and other factors) changes after colorectal cancer surgery. It aims to understand why some people's metabolic syndrome gets better after their tumor is removed, which could lead to better treatments.
Chongqing, Chongqing MunicipalityAges 18 years+ - NCT06708000Enrolling by invitationPhase 3
Personalized testing for new chest pain
This trial compares a personalized evaluation approach to standard care for people with new chest pain who might have heart disease. It aims to see if tailoring tests can improve diagnosis and outcomes.

Mechanical thrombectomy for stroke in the Middle East and North Africa
This study collects information from people who had a stroke from a blocked brain artery and were treated with mechanical thrombectomy (a procedure to remove the clot). The goal is to understand how well this treatment works in the Middle East and North Africa.
Alexandria, Alexandria GovernorateAges Any age - NCT06697509Enrolling by invitation
Better heart scar detection with MRI
This study tests a new way to use heart MRI to find scarring (fibrosis) in the heart muscle. It may help doctors detect heart damage more accurately.
Lørenskog, NorgeAges 18 years+ - NCT06697418Enrolling by invitation
Physical activity and heart health in peritoneal dialysis patients
This study uses a wrist-worn device to see how daily physical activity affects heart health and other outcomes for people on peritoneal dialysis. If you are on PD, can walk on your own, and are willing to wear a tracker, you may be able to join.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06696911Enrolling by invitation

This trial tests if combining mental practice of movements (motor imagery) with core-strengthening exercises helps improve balance and sleep in people who had a stroke 6 months to 2 years ago.
Lahore, Punjab ProvinceAges 40–65 - NCT06690684Enrolling by invitation
Finding new blood markers for heart disease
This study is looking for people who have had a heart attack or have heart failure to discover new markers in your blood that could help doctors better understand and treat heart disease. By collecting samples and health data, researchers hope to find clues that improve care for future patients.
Shanghai, Jing 'an DistrictAges 30 years+ - NCT06688162Enrolling by invitation
Minimally invasive surgery for small brain bleeds
This trial tests a less invasive surgery to remove small blood clots (20–30 ml) in the basal ganglia, a deep part of the brain. It may help people who are awake but have a reduced level of consciousness after a recent brain bleed.
BeijingAges 18–80 - NCT06687044Enrolling by invitation
Sleep therapy for better pregnancy outcomes
This study tests whether a sleep improvement therapy can help pregnant women (with one or two babies) by improving their sleep and pregnancy outcomes. It's for women who are early in their pregnancy and having sleep problems but are otherwise healthy.
Shenyang, LiaoningAges 18–45 - NCT06683872Enrolling by invitation
CT heart modeling for hypertrophic obstructive cardiomyopathy
This trial uses a special CT scan to create a 3D model of your heart's blood flow. It aims to see if this model can help doctors better predict how well treatments work for people with a thick heart muscle that blocks blood flow.
Hangzhou, ZhejiangAges 18–70 - NCT06679946Enrolling by invitationPhase 3
Study of Vutrisiran for heart condition from TTR amyloidosis
This study tests a drug called vutrisiran for people with a condition called transthyretin amyloidosis that affects the heart. It is for patients who have already been in certain earlier studies of patisiran or vutrisiran.
Phoenix, ArizonaAges 18 years+ - NCT06679517Enrolling by invitation
Long-term follow-up for severe aortic stenosis patients considered for TAVI
This study follows patients with severe aortic stenosis (a heart valve condition) who are being evaluated for a keyhole procedure called TAVI. It aims to understand their long-term outcomes after the standard evaluation process.
FerraraAges 18 years+ - NCT06663566Enrolling by invitation
FAPI imaging for right heart function in tricuspid valve leak
This trial uses a special type of PET scan called FAPI to look at how well the right side of your heart is working when you have a leaky tricuspid valve. It may help doctors better understand and manage right heart strain caused by too much blood flow.
Beijing, Beijing MunicipalityAges 18–90 - NCT06659900Enrolling by invitation
