A smarter way to manage hard-to-control high blood pressure
This trial uses a special blood pressure monitor (CART BP Pro) to help guide treatment for people whose blood pressure stays high despite standard care. You may qualify if your blood pressure is still too high even with medication.
AnsanAges 19 years+ - NCT07466056Recruiting
Wearable heart monitor test for hospital patients
This trial tests a new, soft, wearable monitor that tracks your heart and body signs without wires or sticky pads. It aims to see if this device can help doctors diagnose and treat heart disease more comfortably.
Beijing, ChinaAges 18–85 - NCT07466108Recruiting
IV paracetamol during emergency abdominal surgery
This trial tests whether giving paracetamol (Tylenol) through a vein during emergency belly surgery helps keep your blood pressure and heart rate stable. It may be an option for adults who are not critically unstable or have certain serious heart conditions.
Cairo, Cairo GovernorateAges 21–65 - NCT07467187Recruiting

This trial tests whether doing arm exercises at home with a therapist over video can help stroke survivors who have moderate to severe arm problems. It is designed for people who are not already getting outpatient arm therapy.
Edmonton, AlbertaAges 18–80 - NCT07467915Recruiting
Combined mirror therapy and soft robotic glove for hand recovery after stroke
This trial tests if using a soft robotic glove together with mirror therapy can help improve hand and arm movement in people recovering from a stroke. You would wear the glove on your affected hand while looking in a mirror at your unaffected hand, which may help retrain your brain.
Baghdad, BabylonAges 18–70 - NCT07468032Recruiting
Brain stimulation study for stroke patients and healthy volunteers
This study uses brain stimulation (TMS) combined with EEG to understand how the brain controls movement speed after a stroke. It compares healthy volunteers to stroke survivors whose movement has slowed due to network problems, not direct damage to key brain regions.
Amiens, PicardieAges 18 years+ - NCT07468058Recruiting
Diabetic eye disease study in Da Nang
This study looks at how common diabetic retinopathy is and what factors increase the risk. It may help find better ways to prevent vision loss in people with diabetes.
Da NangAges 18 years+ - NCT07468461Recruiting
Camptodactyly-arthropathy-coxa vara-pericarditis (CACP) syndrome study
This study looks at children with CACP syndrome, a rare genetic condition, to learn more about how the condition affects the body over time.
BariAges Up to 18 years - NCT07469163RecruitingPhase 1
Walking on a split-belt treadmill after stroke
This study tests different amounts of walking on a special treadmill that moves each leg at a different speed. It may help people recovering from a first stroke to improve their walking.
Calgary, AlbertaAges 18 years+ - NCT07469371Recruiting
CT-FFR guided heart treatment for severe aortic stenosis
This trial tests whether using a special CT scan (CT-FFR) to guide treatment improves outcomes for people with severe aortic stenosis (a narrowed heart valve). It may help doctors decide between valve replacement surgery or a less invasive procedure.
Kunming, YunnanAges 18 years+ - NCT07469397Recruiting
Study of bleeding after sheath removal in heart ICU
This study looks at what affects bleeding after removing a tube from an artery in the groin (femoral sheath) and how long people need to lie flat. It is for patients in a cardiac ICU who are having the sheath removed.
TaipeiAges 20 years+ - NCT07469943Recruiting
Diabetes drug after heart attack
This study tests whether a diabetes medication can improve artery health and heart function after a heart attack. It is for people who have had a STEMI and also have diabetes or a weakened heart pump.
Athens, Rimini1/HaidariAges 18–80 - NCT07470320Recruiting
Placenta study in healthy and complicated pregnancies
This study looks at how the placenta works in healthy pregnancies and in pregnancies with conditions like pre-eclampsia, gestational diabetes, or fetal growth restriction. It may help find new ways to detect or treat these problems.
OxfordAges 18 years+ - NCT07470580Recruiting
Heat treatment vs surgery for adrenal gland tumor
This study compares two treatments for a certain type of adrenal gland tumor (Conn's adenoma) that causes high blood pressure. One is a heat-based procedure called radiofrequency ablation and the other is surgery to remove the tumor. The goal is to see which is better at controlling blood pressure.
ToulouseAges 18 years+ - NCT07471919Recruiting
Robot vs. visual feedback balance training after stroke
This study compares two types of therapy—robot-assisted walking training and balance training using visual feedback—to see which helps improve walking and balance after a stroke. You may join if you had an ischemic or hemorrhagic stroke, can walk with some help, and have no major communication or vision problems.
BoluAges 21–85 - NCT07472049Recruiting
Imaging plaque activity in peripheral artery disease
This trial studies plaque activity in leg arteries using a new imaging method to understand artery disease better. It may help people with peripheral artery disease get more targeted treatment.
Edinburgh, MidlothianAges 18 years+ - NCT07472660Recruiting
Web-based prevention program after heart failure hospitalization
This trial tests a web-based prevention program for people recently hospitalized with heart failure (with low pumping ability). The goal is to help you stay healthier and avoid another hospital stay.
BremenAges 18–80 - NCT07473102RecruitingEarly Phase 1
PET scan for abdominal aortic aneurysm
This study uses a special PET scan to look for signs of inflammation in abdominal aortic aneurysms (AAA). It may help doctors understand which aneurysms are at risk of growing or rupturing.
St Louis, MissouriAges 18 years+ - NCT07474935Recruiting
Real-world stroke treatment device registry
This trial collects information about the use of a specific stroke treatment device in real-world medical practice. It helps researchers see how well this device works for a wide range of patients, not just those in strict study conditions.
BrestAges Any age - NCT07476040Recruiting
