Coagulation of Middle Meningeal Artery During Brain Bleed Surgery
This trial tests a new technique during surgery for chronic subdural haematoma (bleeding between the brain and skull) where doctors use heat or special tools to seal a blood vessel (the middle meningeal artery) to help prevent the bleed from returning. The goal is to see if this addition to standard surgery is safe and feasible.

Boston, MassachusettsAges 10–35 - NCT07550777Recruiting
Heart Health and Eye Injections Study
This study looks at how repeated eye injections of a drug called bevacizumab affect chemicals in your blood that relate to heart health and inflammation. Researchers want to understand if these eye injections might impact your cardiovascular risk.
Erzurum, ErzurumAges 50–80 - NCT07546656Recruiting
Using Vein Size to Predict Fluid Response in ICU Patients
This study tests whether measuring the size of a vein in your groin using ultrasound can help doctors decide if you need more fluids when you're critically ill in the ICU. The goal is to improve how doctors manage fluid treatment for patients on breathing machines.
Istanbul, IstanbulAges 18 years+ - NCT07547345Recruiting
Community blood pressure help for adults
This pilot study aims to improve access to blood pressure management in community settings. If you have elevated blood pressure readings, this trial may help connect you with resources and support to manage your health.
Chicago, IllinoisAges 18 years+ - NCT07547007Recruiting
Exercise Program to Improve Life Quality After Myeloma Treatment
This study tests whether a 6-month personalized exercise program—done partly at home and partly at a center—can improve quality of life for patients with multiple myeloma (a blood cancer) who are receiving ongoing chemotherapy or targeted drugs. The program is tailored to your abilities and fits into your regular hospital visits.
AnnecyAges 61 years+ - NCT07550036Recruiting
Women-Focused Cardiac Rehabilitation Education Study
This study tests a specialized education program designed for women recovering from heart problems. The goal is to improve how women understand and manage their heart health during rehabilitation.
Barrie, OntarioAges 18 years+ - NCT07549477Recruiting
Heart imaging study for cancer patients with catheter clots
This study uses a special heart imaging test (cardiac MRI) to look for and understand blood clots that may form around central catheters (tubes placed in veins) in people with cancer. The imaging helps doctors see if clots are present and what type they are, which could improve how they care for cancer patients.
Basking Ridge, New JerseyAges 18 years+ - NCT07551011Recruiting
Behavior Change Program for Pregnant Women With Diabetes and High Blood Pressure
This study tests whether a behavior-change toolkit—including guidance on diet, exercise, and stress management—can help pregnant women manage both gestational diabetes (high blood sugar during pregnancy) and pregnancy-related high blood pressure. The goal is to improve health outcomes for you and your baby.
Lahore, Punjab ProvinceAges 15–49 - NCT07545512Recruiting
Finding heart attack risk markers in moderate heart weakness
This study helps doctors identify which heart attack survivors with moderate heart weakness are at highest risk of sudden cardiac death. Researchers will collect health information and heart imaging over 5 years to find early warning signs.
AmiensAges 18–80 - NCT07547098Recruiting
Heart, Kidney, and Metabolism Health Long-Term Study
This research study tracks patients with heart disease, kidney disease, or metabolic conditions (like diabetes) over time to understand how these conditions connect and affect long-term health. By collecting medical records and health information, researchers aim to predict outcomes and improve care.
Fuzhou, FujianAges 18–80 - NCT07545473Recruiting
Eye Imaging to Detect Brain Disease Markers
This study uses a special camera to photograph the back of your eye in detail. Researchers believe changes in the eye may reflect brain diseases like Alzheimer's or Parkinson's, and this imaging could help detect these conditions earlier.
Melbourne, VictoriaAges 30 years+ - NCT07546864Recruiting
Mirror Therapy vs. Daily Activity Training After Stroke
This study compares two rehabilitation approaches—mirror therapy (using a mirror to help retrain your affected side) and cognitive orientation to daily tasks—for people recovering from stroke. The goal is to see which method helps improve arm, hand, and leg function better.

PET scan study of aorta inflammation in aneurysm patients
This research uses a special imaging scan (PET/CT) to take detailed pictures of inflammation in the aorta (the main blood vessel from your heart). Researchers want to understand why some people develop bulges in their aorta called aneurysms. If you have an aneurysm or are a healthy volunteer, this study may help improve how doctors detect and treat this condition.
