Filter by:Vagal Nerve Stimulation is a novel proven therapy for patients with chronic ischemic stroke. The primary objective of this registry is to assess the safety of vagal nerve stimulation for stroke recovery through monitoring the occurrence of serious adverse events associated with the surgical procedure or subsequent paired rehabilitation protocol. This registry will monitor patients undergoing VNS for stroke recovery in the Mount Sinai Health System and collect clinical and procedural details, objective outcomes, and patient-reported outcomes associated with vagal nerve stimulation for stroke recovery.
This is a single-arm post-market study of up to 150 participants, using up to 50 mobile therapists to conduct up to 36-hours at-home therapy. The study will assess at-home therapy implementation instead of an in-clinic therapy implementation for patients who are commercially implanted with the Vivistim System. Patients will be consented for eligibility if appropriate to be implanted with the Vivistim System per the indications for use (The MicroTransponder® Vivistim® Paired VNS™ System is intended to be used to stimulate the vagus nerve during rehabilitation therapy in order to reduce upper extremity motor deficits and improve motor function in chronic ischemic stroke patients with moderate to severe arm impairment.). Study participation includes receiving rehabilitation therapy paired with VNS, provided at the patient's home by a therapist, along with self-activated VNS. All subjects will be commercially implanted with the Vivistim System® after an ischemic stroke prior to Study treatment, although they may be consented prior to implant. It should be noted that the implant surgery is not part of the study.
Objectives: Cerebral small vessel disease (SVD) is a common disease in patients with ischemic stroke and the most common cause of vascular dementia. Blood pressure (BP)-lowering is generally considered neuroprotective. Nevertheless, in patients with severe SVD burden, the optimal BP target is uncertain. Hypothesis: BP-lowering to a systolic BP of 120-129mmHg in ischemic stroke patients with severe SVD is not associated with impaired cerebral perfusion, nor does it associate with worsening of structural connectivity and cognitive function. Design and subjects: One-year trial where patients aged ≥50 with a history of ischaemic stroke and severe cerebral SVD will be randomised (1:1) to a systolic BP target of 120-129mmHg versus 130-140mmHg. Study instruments: At baseline and one-year, all subjects will receive a brain magnetic resonance imaging (MRI) to evaluate their cerebral blood flow (CBF) and white matter integrity. They will also receive neuropsychological batteries to evaluate cognitive functioning. In addition, subjects will receive home BP monitoring with periodic medication changes prescribed by medical doctor to ensure the target BP is achieved. Main outcome measures: Primary end-point is the change in CBF. Secondary end-points include changes in structural connectivity and cognitive performance.
This phase II clinical study is designed to evaluate the safety and efficacy of LT3001 in the treatment of acute ischemic stroke
Researchers are looking for a better way to prevent an ischemic stroke which occurs when a blood clot travelled to the brain in people who within the last 72 hours had: - an acute stroke due to a blood clot that formed outside the heart (acute non-cardioembolic ischemic stroke), or - TIA/mini-stroke with a high risk of turning into a stroke (high-risk transient ischemic attack), and who are planned to receive standard of care therapy. Acute ischemic strokes or TIA/mini-stroke result from a blocked or reduced blood flow to a part of the brain. They are caused by blood clots that travel to the brain and block the vessels that supply it. If these blood clots form elsewhere than in the heart, the stroke is called non-cardioembolic. People who already had a non-cardioembolic stroke are more likely to have another stroke. This is why they are treated preventively with an antiplatelet therapy, the current standard of care. Antiplatelet medicines prevent platelets, components of blood clotting, from clumping together. Anticoagulants are another type of medicine that prevents blood clots from forming by interfering with a process known as coagulation (or blood clotting). The study treatment asundexian is a new type of anticoagulant currently under development to provide further treatment options. Asundexian aims to further improve the standard of care without increasing the risk of bleeding. The main purpose of this study is to learn whether asundexian works better than placebo at reducing ischemic strokes in participants who recently had a non-cardioembolic ischemic stroke or TIA/mini-stroke when given in addition to standard antiplatelet therapy. A placebo is a treatment that looks like a medicine but does not have any medicine in it. Another aim is to compare the occurrence of major bleeding events during the study between the asundexian and the placebo group. Major bleedings have a serious or even life-threatening impact on a person's health. Dependent on the treatment group, the participants will either take asundexian or placebo once a day for at least 3 months up to 31 months. Approximately every 3 months during the treatment period, either a phone call or a visit to the study site is scheduled on an alternating basis. In addition, one visit before and up to two visits after the treatment period are planned. During the study, the study team will: - Check vital signs such as blood pressure and heart rate - Examine the participants' heart health using an electrocardiogram (ECG) - Take blood samples - Ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments. In addition, the participants will be asked to complete a questionnaire on quality of life at certain time points during the study.
The aim of this study is to analyze the relationship between the blood biomarker GDF-15 and heart damage after stroke. It is being conducted in France, in the Neurology Department of the Dijon University Hospital (Burgundy). The research is interventional because a biological blood test will be performed, as well as a heart rhythm recording and several cardiac echograms during the hospitalization of the participants and during the follow-up consultation scheduled 4 to 6 months after the stroke. A total of 130 stroke patients will participate in this study. Participation includes 4 visits: - Inclusion visit (within 24 hours of the first stroke symptoms) - visit 1 (within 24 to 72 hours of stroke) - visit 2 (within 48 hours of visit 1) - Visit 3 (approximately 4-6 months post-stroke)
The goal of this clinical trial is to investigate the use of DECT (Dual-Energy Computed Tomography) in patients with acute ischemic stroke who receive an intervention (thrombolysis or thrombectomy). The main questions to answer are: 1. Can DECT more accurately differentiate hyperdensities as intracranial haemorrhage (ICH) or contrast extravasation compared with single-energy CT (SECT)?. 2. Will DECT lead to better care for patients with AIS who receive intervention and have post-procedural hyperdensities? Patients who receive intervention for acute ischemic stroke (AIS) receive a SECT at 24 hours as standard of care to determine if ICH is present. In the current study, a DECT will be done in addition to the SECT. Followup imaging (SECT or MRI) will be done at 72 hours to determine if the hyperdensity was indeed ICH. The accuracy of DECT for differentiating ICH from contrast extravasation will be compared.
The goal is to pilot test a highly accessible, web-based, pragmatic, scalable intervention to overcome ongoing problems with high stakes decision-making by surrogate decision-makers of patients in ICUs with severe acute brain injury (SABI), including those with moderate-severe traumatic brain injury, large hemispheric acute ischemic stroke and intracerebral hemorrhage.
