Cerebral artery stenosis

This phase 3 trial is testing whether giving a clot-busting drug before mechanical thrombectomy (a procedure to physically remove a blood clot) improves outcomes for people with severe strokes caused by large vessel occlusion. Participants are randomly assigned to receive tenecte…

This pilot study tests whether giving semaglutide (Ozempic) to 100 stroke patients who had a clot-removal procedure can improve recovery. Patients are randomly assigned to receive weekly injections for 12 weeks or no drug. The main goal is to see if a larger, definitive trial is …

This trial compares a procedure to reopen blocked brain arteries (using balloons and stents) against standard medical therapy in people with chronic blockages. The goal is to see if the procedure reduces the risk of stroke or death within a year. Participants have had symptoms fr…

This phase 3 trial tests whether a new emergency stroke unit, equipped with a hybrid CT and X-ray machine (NeuAngio-CT), can speed up clot removal in people having a severe stroke. About 232 adults aged 18-60 with acute ischemic stroke will be randomly assigned to either the new …

This study compares two ways to remove blood clots from the brain during a stroke. About 500 adults who have a stroke from a large blocked artery will be randomly assigned to one of two standard techniques: a cyclic 'plunger' method or a steady suction method. The goal is to see …

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 giving a drug called tirofiban directly into the artery right after a clot is removed can help people recover better from a severe stroke. About 344 adults who had a large-vessel blockage stroke will be randomly assigned to receive the drug or not. The ma…

This study tests a special balloon coated with medicine to open narrowed arteries in the brain and prevent strokes. About 264 people with severe artery narrowing will be treated and followed for 12 months. The goal is to see if the balloon is safe and keeps arteries open better t…

This study tests whether cooling the head (using a special cap) during emergency stroke treatment can reduce the amount of brain tissue that dies. About 182 adults having a major stroke and undergoing a clot-removal procedure will be randomly assigned to receive either standard c…

This study compares two approaches for people who have had a stroke or mini-stroke due to a blocked brain artery that hasn't opened on its own. One group gets a procedure to reopen the artery plus medication, while the other gets medication alone. The goal is to see which approac…

This study tests whether giving a clot-busting drug called tenecteplase directly into the brain artery can help stroke patients who still have blocked blood flow after a standard clot removal procedure. About 344 adults with a major stroke will be randomly assigned to receive eit…

This study tests whether sending people with suspected severe stroke directly to the angiography suite (instead of first getting a CT or MRI) can speed up treatment and improve recovery. About 568 adults with stroke symptoms within 6 hours will be randomly assigned to the direct …

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 phase 3 trial tests whether giving a clot-busting drug called rhPro-UK before a mechanical clot removal procedure improves recovery for people with severe stroke. About 820 participants who had a stroke 4.5 to 24 hours earlier will receive either the drug or a placebo, follo…

This Phase 2 trial tests whether giving human albumin directly into the artery supplying the brain, right after a clot is removed, can improve recovery in people with severe stroke. About 306 participants will be randomly assigned to receive either standard clot removal alone or …

This study tests whether giving a clot-busting drug directly into the brain artery, plus possibly removing the clot with a device, helps people with medium-sized stroke clots. About 614 participants who cannot receive standard IV clot-busters will be randomly assigned to either t…

This study tests whether giving a protein called albumin directly into the artery during a stroke procedure can reduce brain damage. Sixty adults with a severe stroke will receive either standard treatment alone or standard treatment plus albumin. The goal is to see if albumin he…

This study tests a new balloon microcatheter in 56 people with severely narrowed brain arteries (70% or more blockage). The device can both widen the artery and deliver other treatments. Researchers will check if it works safely and effectively, tracking complications like stroke…

This study tests whether the clot-busting drug tenecteplase can improve recovery in people who have a major stroke caused by a large blocked artery, but who cannot have a procedure to remove the clot. The trial includes 794 adults who arrive at the hospital 4.5 to 24 hours after …

This study will test a new rapid blood test that can be done at the bedside to help doctors quickly tell if a child is having a stroke. About 250 children with stroke symptoms will give a small blood sample, and the test's accuracy will be compared to standard brain scans. The go…

This study looks at whether inflammation levels differ on either side of a blood clot in the brain during a stroke treatment called mechanical thrombectomy. Researchers will compare blood samples taken from before and after the clot to see if the difference is linked to how well …

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 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 will analyze eye and brain scans from over 200,000 people to see if eye images can predict brain diseases like small vessel disease and other health problems. Researchers will build computer models to map eye features to brain structure and disease diagnoses. No treatm…

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 whether lying flat (0 degrees) or with the head raised (30 degrees or more) after a stroke clot removal procedure helps people recover better. About 2240 adults who had a stroke from a large blood vessel blockage will be randomly assigned to one of the two hea…

This study looks at 958 people having a severe stroke to find out if general anesthesia (being fully asleep) or procedural sedation (being drowsy but breathing on your own) leads to better recovery after a procedure to remove a blood clot from the brain. Participants will be rand…
