Filter by:The goal of this observational study is to evaluate the accuracy of a panel of blood biomarkers and clinical variables in predicting the prognosis of stroke patients treated by mechanical thrombectomy, specifically to predict futile recanalization and mortality.
Post-ischemic adaptation is a physical brain protective treatment strategy in which an ischemic event in an organ or tissue is treated and blood flow is restored, and an ischemic stimulus is given to local tissues to induce the production of anti-ischemic damage factors and reduce the damage associated with reperfusion therapy . Relevant basic studies have confirmed that post-ischemic adaptation can reduce infarct volume and promote neurological function recovery in animal models of cerebral infarction. Therefore, it may be beneficial to the recovery of neurological function in patients with acute ischemic stroke undergoing mechanical thrombus extraction. Based on the above background, the use of a balloon to repeatedly dilate-contract at the original occlusion site after revascularization to block and restore arterial flow may be an effective cerebroprotective treatment for patients with large-vessel occlusion who undergo thrombolysis. However, can this approach be safely used in patients with acute ischemic stroke treated with thrombolysis? What is the protocol for the length of time patients can tolerate post-ischemic adaptation? The application of this method in the treatment of acute ischemic stroke will be explored in this study.
The purpose of this study was to evaluate the effectiveness of early administration of BXOS110 for injection in reducing overall disability in patients with acute ischaemic stroke.
Phase III Clinical Trial of GD-11 for Injection in the Treatment of Acute Ischemic Stroke - A Multi-Center, Randomized, Double-Blind, Parallel, Placebo-Controlled Phase III Clinical Study with the primary objective of evaluation of the efficacy and safety of GD-11 for injection in the treatment of acute ischemic stroke patients within 48 hours. The subject has a clinical diagnosis of acute ischemic stroke, within 48 hours from stroke onset to start of study treatment, with a National Institutes of Health Stroke Scale (NIHSS) between 6 and 20, had a total score of upper and lower limbs on motor deficits ≥ 2. The primary outcome is the proportion of subjects with mRS score ≤ 1 at 90 days after treatment.
Acute ischemic stroke with large vessel occlusion is a frequently occurring life-threatening condition. Although endovascular treatment can effectively open occluded vessels, the successful reperfusion rate exceeds 80%, but the rate of good prognosis is less than 50%. The current clinical focus is on how to improve futile recanalization. Tirofiban is widely used in the treatment of stroke, as it can effectively prevent vascular reocclusion and improve microcirculation perfusion. It has the potential to improve futile recanalization, but there is a lack of high-level evidence-based medical support. This multicenter, prospective, double-blind, randomized controlled trial was conducted to assess the effectiveness and safety of sequential tirofiban therapy following successful mechanical thrombectomy within 24 hours of onset.
Affecting more than 150,000 patients in France, stroke is a major public health issue and a leading cause of disability worldwide. In western countries, 80-85% of strokes are of ischemic subtype. This study will focus on young adults, aged 18-45, with a diagnosis of ischemic stroke. Studies assessing post-stroke cognition in young patients reported an alarming prevalence of cognitive impairment, affecting about 60% of stroke survivors between 4 and 12 months after the acute event. However, longitudinal data on neurocognitive trajectories (i.e., the evolution of cognitive impairment over time) in young patients with ischemic stroke are lacking. Collecting such data requires an exhaustive neuropsychological assessment and several functional evaluations, at different times, for the same patient. Repeated neurocognitive study of young patients with ischemic stroke will enable: a description of the prevalence of impaired global cognitive efficiency, an analysis of the specific neurocognitive domains affected, and the tracing of trajectories of recovery from cognitive impairment over time, in terms of global cognitive efficiency and as a function of specific neurocognitive domains (memory, executive, attentional, social cognition, instrumental functions, fatigability, etc.). Up to date, the clinic-radiological predictors and associated factors of neurocognitive impairment after ischemic stroke in young patients have not been studied. Ischemic stroke causes acute brain lesions of the gray matter (GM) and white matter (WM). Numerous studies suggest that cognitive health may be more closely linked to the integrity of WM than to GM. Magnetic resonance imaging (MRI), and in particular diffusion tensor imaging (DTI) sequences, analyze WM bundles. By using fiber tracking algorithms image analysis enable the WM fiber bundle reconstruction and allow quantifying the volume of lesions (pre-existing and ischemic stroke-induced) in the WM tract. The aim of this study is to study whether the extension of pre-existing and acute white matter lesions is associated with poorer cognitive recovery after ischemic stroke, both in terms of global cognitive performance and impairment in specific neurocognitive domains.
The study is a prospective multicentre registry study. Patients admitted to 10 stroke centres nationwide from September 2022 to September 2025 with acute ischaemic stroke due to large vessel occlusion considering underlying ICAS and treated with emergency endovascular thrombolysis were included for analysis. Patients who met the general inclusion criteria underwent thrombectomy and the necessary remedial treatment.
In this study, a multicenter, randomized, controlled, prospective cohort study was conducted to observe the effect of Edaravone Dexborneol on the incidence and outcome of bleeding transformation after thrombolysis in acute ischemic stroke. To explore the methods to reduce the dilemma of bleeding transformation after thrombolysis, and to dynamically detect the changes of the main links causing bleeding transformation such as blood-brain barrier damage, local immune response activation and so on. To explore the mechanism of Edaravone Dexborneol in reducing bleeding transformation. It is proved that Edaravone Dexborneol combined with thrombolytic therapy can reduce the risk of bleeding and transformation after thrombolysis and improve the safety of thrombolysis. Secondly, it can improve the early recanalization rate of ischemic stroke patients after thrombolytic therapy, and effectively protect the integrity of the blood-brain barrier.
(1) The main purpose To explore the predictive value of human microbiome and its metabolome for adverse prognosis in patients with acute ischemic stroke (AIS). (2) Secondary purposes 1. To explore the characteristics of cross-regional disturbance of human microbiome in stroke patients; 2. To investigate the characteristics and rules of bacterial flora changes before and after recurrent apoplexy; 3. Markers closely related to AIS prognosis and cognitive emotional complications were excavated by metagenomic, metabolic, peptide and imaging groups. 4. To explore the relationship between serum markers of ultra early stage and prognosis.
