Blood pressure during surgery and recovery after Whipple procedure
This trial looks at how low blood pressure during a Whipple procedure (pancreaticoduodenectomy) affects lactate levels after surgery, which is a marker of how well your body is recovering. It helps doctors understand how to manage blood pressure to improve outcomes.

Study of sex chromosome disorders in fetuses and children
This study looks at the genetic and physical health of babies and children who have a sex chromosome disorder (like having an extra or missing X or Y chromosome). It also compares them to children without these conditions. The goal is to learn more about how these disorders affect development.

Heart MRI study for early heart failure with preserved pump function
This trial uses advanced MRI scans to study early signs of heart failure in people whose heart pumps normally but who have risk factors like diabetes, high blood pressure, or obesity. It aims to improve detection and understanding of this condition.
Ages Any age - NCT07336290Enrolling by invitation
One-stop MRI for hypertrophic cardiomyopathy
This study uses a single, advanced heart MRI to get a complete picture of hypertrophic cardiomyopathy—a condition where the heart muscle is thickened. It aims to make diagnosis and treatment planning faster and easier for patients.
Ages Any age - NCT07332897Enrolling by invitation
Neck exercises plus motor relearning after stroke
This study tests whether adding neck stabilization exercises to a standard motor relearning program helps people who have had a recent stroke improve their movement and function better than the motor program alone.
Lahore, Punjab ProvinceAges 35–65 - NCT07330882Enrolling by invitation
Heart health app study for coronary disease
This study tests a smartphone app to help people with coronary heart disease manage their health. You may be eligible if you have been diagnosed with coronary heart disease, can use a smartphone, and have no serious health issues that would limit exercise.
BengbuAges 18–80 - NCT07325968Enrolling by invitation
Heart MRI Study for Myocarditis and Heart Inflammation
This study uses a special heart MRI to look closely at inflammation in the heart muscle. It helps doctors better understand and treat myocarditis and inflammatory cardiomyopathy.
Ages Any age - NCT07323667Enrolling by invitation
Study of a first responder system for cardiac arrest in Zug
This trial is studying a new system where trained volunteers respond quickly to help people whose heart stops outside of a hospital in Zug, Switzerland. The goal is to see if this system improves survival and recovery.
Zug, Canton of ZugAges 18 years+ - NCT07320677Enrolling by invitation
Finding Heart Failure in People Taking Water Pills
This study is for people who take a type of water pill called a loop diuretic, but do not yet have a diagnosis of heart failure. The study will check a blood test to see if undiagnosed heart failure might be present.
Saint HelierAges 18 years+ - NCT07317882Enrolling by invitation
Video education program for heart failure
This trial will test a remote education program for people with heart failure. You'll get video calls and learning materials to help manage your condition from home.
Cadiz, CádizAges 18 years+ - NCT07316075Enrolling by invitation
Heart and metabolic health in silent pheochromocytoma or paraganglioma
This study looks at heart and metabolic health in people who have pheochromocytomas or paragangliomas that do not produce extra hormones. It aims to understand whether these 'silent' tumors affect cardiovascular and metabolic health, and how they compare to other cases.
AthensAges 18 years+ - NCT07312136Enrolling by invitation
Liver health follow-up in type 2 diabetes
This study follows up on people who already joined the EPSONIP trial to check how their liver health (MASLD) has changed over time. It uses MRI to look at the liver and does not test any new medicine.
Linköping, Östergötland CountyAges 18 years+ - NCT07307924Enrolling by invitation
Can motivational talks help with high blood pressure?
This study tests whether talking with a health coach (motivational interviewing) can help people with high blood pressure better understand their condition, feel more confident managing it, and stick with their treatment. It focuses on people living in semi-rural areas.
