Testing a drug to prevent kidney injury after heart surgery
This study tests a new medicine, BX-001N, to see if it can prevent kidney damage during and after heart surgery for aortic disease. It is for people with moderate kidney problems who are having planned surgery that stops the heart briefly.
DaeguAges 19–90 - NCT07674004Recruiting
Testing a new flow diverter for brain aneurysms
This trial tests a special metal mesh tube, called a flow diverter, to treat unruptured brain aneurysms. The goal is to see how safe and effective it is for preventing strokes.
Zhengzhou, HenanAges 18–75 - NCT07531602Enrolling by invitation
How breathing pressure affects heart function during surgery
This study observes how different levels of breathing support during heart surgery affect your heart's function. Researchers will use ultrasound and monitoring tools already planned for your surgery to see how small changes in breathing pressure impact your heart's performance.
Boston, MassachusettsAges 18 years+ - NCT07526987RecruitingPhase 3
Minocycline to Help Recovery After Acute Stroke Treatment
This study tests whether an antibiotic called minocycline, given alongside standard stroke treatment (clot-busting medication), can help reduce brain damage and improve recovery. You would receive minocycline around the time of your clot-busting treatment.
Liaocheng, ShandongAges 18–80 - NCT07518251Recruiting
Bypass Techniques for Complex Aortic Aneurysm Surgery
This trial compares two different surgical approaches to repair a life-threatening tear or bulge in the large artery that carries blood from the heart (aorta). The study will help doctors determine which technique is safer and works better for patients needing this complex surgery.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07346222Recruiting
San Matteo endocarditis patient study
This study looks at patients diagnosed with infective endocarditis (a serious infection of the heart's inner lining) to learn more about the condition and improve care. If you have been diagnosed with infective endocarditis at a specific hospital, you may be able to join.
Pavia, LombardyAges 18 years+ - 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+ - NCT07347691Recruiting
AI predicts atrial fibrillation after stroke of unknown cause
This trial uses an artificial intelligence (AI) program to see if it can predict which patients who had a stroke from an unknown cause might develop atrial fibrillation (an irregular heart rhythm). If you have a small heart monitor already implanted, the AI will analyze your ECGs to find early signs of AFib, which could help prevent future strokes.
AnsanAges 30 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+ - NCT07348458Recruiting
Kidney protective jacket trial
This trial tests a special jacket designed to protect a donor kidney before transplant. It may help the kidney work better after surgery.
Westmead, New South WalesAges 18 years+ - NCT07349004Recruiting
Migraine with aura and PFO study
This study looks at the link between migraine with aura and a small hole in the heart called PFO. It may help researchers understand what causes migraines in some people.
Bologna, BOAges 18 years+ - NCT07349030Recruiting
Fall risk intervention for stroke patients in rehab
This trial tests a program to help stroke patients in inpatient rehab reduce their risk of falling. It uses a stepping and obstacle test to identify who is at risk and then provides an intervention to improve balance and mobility.
Boston, MassachusettsAges 45–85 - 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 - NCT07349875RecruitingPhase 4
Colchicine for non-severe coronary plaque: a trial
This trial tests if the anti-inflammatory drug colchicine can help people with non-severe coronary artery plaque seen on a CT scan. It may be an option if you have stable chest pain or related symptoms and your heart arteries are partly blocked but not severely.
NanjingAges 18 years+ - NCT07350460Recruiting
Comparing two pain blocks for hemorrhoid surgery
This study tests two types of numbing injections (a pudendal block and a sacral ESP block) to see which works better for pain after hemorrhoid surgery. If you're scheduled for this surgery, you might qualify to help find a better way to manage pain.
BellinzonaAges 18–80 - 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+ - NCT07350759Recruiting
Using a wearable to detect heart failure worsening
This study tests if a wearable device can spot early signs of heart failure getting worse. If you already use a heart monitor and have stable readings, you may help show how a non-invasive wearable could alert you sooner.
Tampa, FloridaAges 18 years+ - NCT07351422Recruiting
A survey on Takayasu arteritis care in the UK
This UK-based study uses a questionnaire to learn about how people with Takayasu arteritis (a rare type of vasculitis) are treated and what they think about their care. If you have TAK, your answers can help doctors understand how to better manage this condition.
EdinburghAges 18 years+ - 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+ - 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.

TaipeiAges 18–95 - NCT07352111Recruiting
Heart risk in those with family history of heart attack

MilanAges 40–70 - NCT07352358RecruitingPhase 4
Blood thinners plus batroxobin for brain vein clots
This trial tests whether adding a medication called batroxobin to standard blood thinners can help treat blood clots in the veins of the brain better than blood thinners alone. It is for people who have been diagnosed in the last month and are not at high risk for bleeding.
Beijing, Beijing MunicipalityAges 18–80 - NCT07352800RecruitingPhase 2
Study of APAC for peripheral artery disease and severe leg ischemia
This trial tests a new drug called APAC to see if it safely prevents blood clots and improves blood flow in people with narrowed leg arteries. It may help those with severe symptoms like pain at rest or non-healing wounds, or those with claudication (leg pain when walking).
