AmiensAges 18 years+ - NCT07347925Recruiting
Study of heart failure medicine before hospital
This trial tests if a specific heart failure pill, started before hospital care, helps improve short-term outcomes in people with weak heart muscles. It is for patients with a low pumping ability of the heart.
Al MansurahAges 18 years+ - NCT07351838Recruiting
Heart MRI for risk screening in early cardiomyopathy
This study uses heart MRI to find people with early signs of heart muscle disease who still have normal-sized heart chambers. It aims to better predict who is at risk so they can get earlier care.
BeijingAges 16 years+ - NCT07344701Recruiting
Screening for diabetes and heart disease risk in Ascoli Piceno
This study screens people in Ascoli Piceno for early signs of diabetes and heart disease and offers prevention steps. It's for people turning 50 in 2026 who haven't already had both diabetes and a major heart problem.
Ascoli Piceno, Ascoli PicenoAges 50–50 - NCT07351786Recruiting
Newer diabetes drugs and eye protection study
This trial is looking at whether newer diabetes drugs (like SGLT2 inhibitors and DPP-4 inhibitors) can help protect the eyes of people with long-standing type 2 diabetes. The study focuses on preventing or slowing diabetic retinopathy, a common eye complication.
AlexandriaAges 25 years+ - NCT07343661Enrolling by invitationPhase 4
Mepolizumab study for asthma or EGPA
This trial tests how well mepolizumab works for people with asthma or a related condition called EGPA, and looks for markers in the blood that may predict organ damage or treatment response.
Cagliari, CagliariAges 18 years+ - NCT07351656Recruiting
AI heart checks for young adults, adults, and pregnant women
This study uses artificial intelligence (AI) to look at heart signals (electrocardiography or ECG) and ultrasound images of the heart to check for heart disease. It aims to better understand heart health in different groups of people.
Rochester, MinnesotaAges 18 years+ - NCT07352111Recruiting
Heart risk in those with family history of heart attack
This study looks at people who have a family history of heart disease but no known heart problems or symptoms. It aims to understand if hidden plaque buildup in the arteries may be present.
MilanAges 40–70 - NCT07349277Recruiting
Predicting preeclampsia with blood tests in pregnancy
This study tests if certain blood markers can help diagnose and monitor preeclampsia. It aims to improve how this serious pregnancy condition is detected and treated.
Nasiriyah, Dhi QarAges 18–45 - NCT07345533Recruiting
Heart Failure Monitoring with a Chest Sensor
This study tests a small chest sensor that tracks your heart activity while you're in the hospital. It may help doctors better manage heart failure and prevent future crises.
CaenAges 18–90 - NCT07350564Recruiting
Comparing tight vs. usual blood pressure control after stroke clot removal
This trial tests whether keeping blood pressure very tightly controlled after a stroke clot removal (thrombectomy) is better than standard care. It may help people who have had an acute stroke from a large brain artery blockage and still have high blood pressure after the procedure.
Suzhou, JiangsuAges 18 years+ - NCT07351825Recruiting
Heart MRI study for people with ischemic heart disease
This study uses heart MRI scans to find markers that predict outcomes in people with ischemic heart disease, including those who have had a heart attack. It may help doctors better understand your condition and guide future care.
Beijing, Beijing MunicipalityAges Any age - NCT07347587Recruiting
Finding the right blocked artery in stroke using CT scans
This study looks at how well different CT scans can identify which artery is blocked in people having a stroke. It may help doctors choose the best treatment faster.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07345702Recruiting
Endovascular therapy for large core posterior stroke
This trial tests endovascular therapy (a procedure to remove a clot through a tube in an artery) versus medical management for people with a severe stroke due to a blockage in the back part of the brain (basilar artery) and a large area of brain damage. The goal is to see if the procedure improves outcomes compared to medication alone.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07343674Recruiting
