Carotid stenosis

This study tests a stent (Carotid WALLSTENT) used with a special brain protection system (ENROUTE NPS) in 60 Chinese patients with narrowed carotid arteries. The goal is to see if the combination can be safely delivered to prevent strokes. Patients must have significant artery na…

This study tests whether secukinumab, a drug that blocks inflammation, can reduce the risk of major heart problems and kidney decline in people with cardiorenal metabolic syndrome and hardened arteries. About 100 adults will receive either secukinumab injections plus standard car…

This trial tests whether using a balloon guide catheter along with a filter can better protect the brain during carotid artery stenting. People with narrowed neck arteries (carotid stenosis) who need stenting are randomly assigned to get either the balloon-plus-filter combo or a …

This study tests whether a personalized weaning strategy can help adults with chronic heart, brain, or lung conditions leave ventilators earlier. The strategy tailors care based on the main reason a patient struggles to breathe on their own, such as heart or muscle problems. Rese…

This study tests whether adding alirocumab (a cholesterol-lowering injection) to standard statin therapy can reduce bleeding inside fatty plaques in the carotid artery. About 280 people with a recent mini-stroke or stroke due to a 50-69% blocked neck artery will receive either al…

This study tests whether using a balloon guide catheter during carotid artery stenting can prevent small particles from traveling to the brain and causing strokes. About 126 people with narrowed neck arteries will be randomly assigned to receive the balloon protection or standard…

This study tests a community-based exercise program for people aged 50 and older who have at least two chronic conditions, such as heart disease, diabetes, arthritis, or obesity. The program is designed to improve muscle strength, heart and lung fitness, and overall well-being. R…

This study tests a new type of catheter (a thin tube) designed to make carotid artery stenting easier and safer when done through the wrist. About 204 people with blocked neck arteries will be randomly assigned to get the new catheter or a standard one. The main goal is to see if…

This study tests a new device called SwitchGuard NPS that is designed to catch loose debris and protect the brain during a procedure to open narrowed neck arteries. About 103 people with carotid artery stenosis who are at high risk for standard surgery will receive the device alo…

This study tests a new 3D ultrasound imaging method to map blood vessels in the heart and brain of people with atherosclerosis who are scheduled for carotid surgery. The goal is to see if this non-invasive, radiation-free technique can detect blockages and incomplete vessel netwo…

This study tests whether adding the drug dexmedetomidine during carotid artery surgery helps keep blood pressure more stable. About 44 adults having this surgery will be randomly assigned to receive either standard anesthesia alone or standard anesthesia plus dexmedetomidine. The…

This large registry study will follow over 2,700 postmenopausal women aged 45-75 who use newer forms of hormone replacement therapy (creams, gels, sprays). The goal is to see if these modern delivery methods lower the risk of heart attacks, strokes, and other cardiovascular event…

This study looks at two common anesthetics used during carotid artery surgery to see which one better protects the brain from small areas of damage. About 160 adults having planned carotid surgery will get either an intravenous or inhaled anesthetic. Researchers will compare brai…

This study compares two ways to perform brain angiography: accessing an artery through the wrist (transradial) versus the groin (transfemoral). Over 2,400 people needing this imaging test will be randomly assigned to one method. Researchers will measure success rates, complicatio…

This study aims to develop a new EEG-based technique to detect 'cognitive-motor dissociation'—where a patient is aware but cannot move. Researchers will stimulate the median nerve (in the wrist) and analyze brain signals in 50 comatose ICU patients. The goal is to identify those …

This study will look at brain scans (MRI/CT) and symptoms of over 1,100 people with cerebrovascular disease. The goal is to find patterns linking specific scan findings to different types of the disease. This could help doctors diagnose and treat these conditions more accurately …

This study looks at a protein called GARP in artery plaques from 200 patients having surgery to clear blocked arteries. The goal is to understand how GARP, which is found on platelets and immune cells, might be involved in the inflammation that causes heart attacks and strokes. N…

This study aims to discover new reasons why blood clots form in people with heart disease, diabetes, and other illnesses. Researchers will analyze blood samples from 200 patients with narrowed neck arteries to look for markers of cell damage and clotting factors. The goal is to f…
