Filter by:First prospective, single-arm, multicentre study to evaluate the safety and efficacy of the overall stroke thrombectomy system: INEDIT, INDEEP and INTERCEPT in patients with acute ischemic stroke.
The objective of the study is to assess brain tissue perfusion by contrast-enhanced ultrasound perfusion imaging (PerCEUS) in acute brain injuries. More precisely, it aims : - to evaluate the heterogeneity of brain perfusion and thus diagnose brain tissue hypoperfusion with contrast-enhanced ultrasound. - to correlate contrast-enhanced ultrasound with perfusion measurements by usual multimodal monitoring.
The investigator aims to find a correlation between brain structure and activity and spontaneous recovery of motor function following brain ischemic stroke by Analysis of MRI scans. The research includes stroke patients and healthy patients (control group).
Posterior circulation stroke accounts for 20% of all ischemic stroke. Approximately one quarter of posterior circulation strokes are due to stenosis in the vertebral artery and basilar artery. Two previous randomized controlled trials focusing on vertebral artery stenting, the Vertebral Artery Stenting Trial (VAST) and the Vertebral Artery Ischaemia Stenting Trial (VIST) were underpowered because they failed to reach target recruitment, and both the trials found no difference in risk of the primary outcome between the stenting group and medical group. The drug-eluting stenting versus medical therapy alone for patients with extracranial vertebral artery stenosis (VISTA) trial, is a government-funded, prospective, multicenter, randomized controlled trial. It will recruit patients with 3 months stroke or TIA caused by 70-99% stenosis of extracranial vertebral artery (V1-2 segments). Only high-volume center with a proven track record will enroll patients. Patients will be randomized (1:1) to best medical treatment alone or medical treatment plus stenting. Primary outcome is a composite of any fatal or non-fatal stroke within 30 days after randomization, or ischemic stroke in the territory of the target artery beyond 30 days to 1 year. The VISTA trial will be conducted in 30 sites in China and aims to have a sample size of 472 subjects (stenting, 236; medical treatment, 236). Recruitment is expected to be finished by Sep, 2025. Patients will be followed for 1 year at first stage. Long-term follow-ups till 3 years or longer is also preplanned. The first stage of the trial is scheduled to complete in 2027.
The aim of this study is to evaluate the effect of early rehabilitation treatment by electroencephalographic neurofeedback on upper limb motor function after stroke. Researchers will compare : Interventional group: electroencephalographic neurofeedback + traditional reference rehabilitation programme Control group: SHAM electroencephalographic neurofeedback + traditional reference rehabilitation programme
High-intensity statins are recommended for secondary prevention of stroke in patients with atherosclerotic ischemic stroke. According to the guidelines of the American Heart Association and the American Stroke Society, high-intensity or high-dose statins are recommended for high-risk groups of atherosclerotic cardiovascular disease (ASCVD). Statin therapy is recommended even if it is less than 100 mg/dL. The 2016 ESC/EAS and 2017 AACE guidelines include ischemic stroke and transient cerebral ischemic attacks caused by atherosclerosis in ASCVD, classifying them as ultra-high-risk groups, and recommending LDL cholesterol of less than 70 mg/dL as a treatment goal. The recently published guidelines for dyslipidemia in Korea also recommend that the target level of LDL cholesterol in patients with atherosclerotic ischemic stroke and transient ischemic attack be reduced to less than 70 mg/dL or 50% or more from the baseline. According to a previous study on the efficacy and safety of high-intensity rosuvastatin in patients with ischemic stroke, it is not clear whether the use of rosuvastatin 20 mg prevents recurrence of cerebral infarction in the acute stage, but it is safe and effective for hemorrhagic conversion of cerebral infarction. In addition, the results were shown when rosuvastatin and ezetimibe were combined in patients with high cardiovascular risk, LDL cholesterol and total cholesterol decreased more in the combined group than in the single agent group. In a study comparing the group whose LDL cholesterol target was reduced to 70 mg/dL or less after stroke and the group maintained at 90-110 mg/dL, the group whose LDL cholesterol was controlled to 70 mg/dL or less It was confirmed that the incidence of cardiovascular disease was reduced. Existing studies aimed at general high-risk groups, not specific disease groups, and as in this study, studies were not conducted on a single disease group called acute stroke. In addition, there are only limited studies on the effectiveness and safety of diseases that occur mainly in the elderly, such as acute stroke. Therefore, there are currently no studies on the clinical efficacy and safety of high-intensity rosuvastatin and ezetimibe combination therapy for patients with acute cerebral infarction.
The goal of this interventional study is to learn about the clinical outcomes of acute ischemic stroke treated with mechanical thrombectomy resulting in a selective ischemia of the basal ganglia. The main question it aims to answer is: • defining the prevalence and clinical features of possible cognitive, motor and sleep disfuncions occuring after acute ischemic stroke treated with thrombectomy Participants will be tested for cognitive, movement and sleep disorders in the acute phase and successively in the long term follow-up.
Evidence suggests that oxytocin has a neuroprotective role on a systemic and cellular level in the context of acute ischemic stroke (AIS). The investigators therefore hypothesize that high levels of circulating oxytocin measured within the first 72 hours after symptom onset are associated with lower mortality and favorable outcome in acute ischemic stroke.
Introduction Remote cerebral hemorrhage following reperfusion treatment in ischemic stroke is rare (1.3-3.7% of all treated strokes) and is associated with worse functional and vital prognosis. Multicenter observational studies suggest that amyloid angiopathy may be one of the main risk factors for remote hemorrhage. Currently, it is unknown what happens to those patients with remote hemorrhage beyond 3 months of follow-up in terms of risk/benefit balance when receiving antiplatelet or anticoagulant therapy, as well as from a cognitive point of view. Considering an analogy with amyloid angiopathy, the hypothesis is that those patients with remote hemorrhage have a higher risk of intracranial hemorrhage during follow-up when receiving stroke secondary prevention, and will also present greater cognitive deterioration during long-term follow-up. Main Objectives - To explore the frequency and risk factors for intracranial hemorrhage during follow-up of patients with remote cerebral hemorrhage. - To explore the frequency and progression of cognitive deterioration during follow-up in patients with remote cerebral hemorrhage. Methodology Observational, prospective, multicenter registry with a population-based case-control design of consecutive patients with remote hemorrhage following reperfusion therapy in acute ischemic stroke. Inclusion criteria: Diagnosis of ischemic stroke with age greater than or equal to 18 years who has remote cerebral hemorrhage after receiving reperfusion therapy in the acute phase. Exclusion criteria: Lack of basic data (age, sex, neuroimaging data) or telephone for follow-up. The cases will be those patients with remote hemorrhage. For each case included, 4 consecutive controls will be included (2 with local parenchymal hemorrhagic transformation and 2 without hemorrhagic transformation). The data will be filled out within the (Codi Ictus de CATalunya) CICAT registry form (currently mandatory in all stroke centers in Catalonia) to which additional variables will be added. Telephone follow-up will be conducted at 3, 12, and 24 months. Main study variable: - Any type of spontaneous or traumatic intracranial hemorrhage during a 24-month follow-up. - Score on the "Short Informant Questionnaire" scale (a validated 17-question questionnaire to be conducted over the phone, where a score higher than 57 points indicates cognitive impairment). Expected sample size during a 2-year recruitment period: 105-300 patients (considering the participating centers to date). Additional information. This study is endorsed by the "Pla Director de la Malaltia Vascular Cerebral" in Catalonia. Participating Centers. Participation offers have been sent to the 28 hospitals in the hospital network of Catalonia with the capacity to administer intravenous fibrinolysis. Positive responses have been received from 13 of them so far. In case the project is accepted by the (Comité Ético de Investigación Clínica) CEIC Sant Pau, the centers that have not responded will be contacted again to obtain their participation.
Study using ultrasound of the brain as a diagnostic tool to differentiate between ischemic stroke and hemorrhagic stroke. Correlation of brain perfusion and size of stroke in relation to systemic hemodynamic targets will be assessed on serial scans.
