Active clinical trials for "Ischemic Stroke"

Brain is a productive source of variety of enzymes and any brain injury like stroke to brain tissue could similarly result in an increase in these enzymes in cerebrospinal fluid and serum. Evaluation of these enzymes represent a simple method for the ischemic stroke subtype diagnosis and prognosis .Objective: The aim of this study was to determine the role Brain natriuretic peptide (BNP) , D-Dimer , creatine kinase- MB(CK-MB) , C reactive protein (CRP) serum levels and G/A ratio in diagnosis of CES stroke and its ability to predict short term outcome. Methods: This study was conducted on 96 patients with acute ischemic stroke, subdivided into two groups, group Ι was 48 patients with cardio-embolic stroke and group ΙΙ was 48 patients with non- cardio-embolic. all patients were subjected to assessment of serum BNP, D-Dimer and CK-MB and CRP and globulin /albumin ratio within the first 24 h of stroke .At third week ,they were assessed by mRS.

Stroke remains the leading cause of disability in the United States. An estimated 40-50% of all ischemic strokes are caused by large-vessel occlusion of a major cerebral artery (LVO). However, in some cases, the occlusion results in mild symptoms, at least initially, and these patients frequently do not receive any treatment. These strokes, however, may result in unfavorable long-term outcomes despite relatively benign initial course. Recent large randomized studies in patients with severe stroke symptoms and associated LVO showed efficacy and safety of endovascular mechanical thrombectomy, but patients with mild symptoms were not specifically addressed. Based on the investigators' own data and limited evidence in the literature, the investigators propose that early mechanical thrombectomy in patients with LVO associated with mild stroke symptoms (defined as NIHSS ≤ 5) is safe, and results in favorable long-term patient outcomes. The objective of this prospective pilot study is to assess the safety and outcomes of mechanical thrombectomy in patients presenting with acute ischemic stroke due to a large vessel occlusion in the anterior or posterior circulation under 24 hours with mild symptoms (NIHSS ≤ 5).

The objective of this post-market registry is to assess technical efficacy and safety associated with the use of the BOSS Balloon Guide Catheter during neuro-vascular procedures while providing temporary arrest of blood flow.

This is a prospective, multicenter, single-arm, open-label, national Post-Market Clinical Follow-up study to collect comprehensive information on technical and clinical success and safety of the use of APERIO® Hybrid(17/21) Thrombectomy Device in clinical practice. APERIO® Hybrid(17/21) Thrombectomy Device will be used within its approved indication.

This is a retrospective real world registry study, aiming to explore the effectiveness and safety of endovascular treatment of acute ischemic stroke in a Chinese population.

This clinical trail will evaluate the effect of Sanchitongshu combined with antiplatelet drugs (Aspirin or Clopidogrel) in the treatment of high-risk ischemic stroke patients in adults. Half of participants will receive SanchiTongshu and one of antiplatelet drugs (Aspirin or Clopidogrel) in combination, while the other half will receive a placebo and one of antiplatelet drugs (Aspirin or Clopidogrel).

In this pilot trial, the investigator will compare early post-stroke BP management using an integrated Telehealth After Stroke Care (iTASC), to usual care with a primary outcome of BP control defined by the mean 24-hr blood pressure through remote monitoring at 3 months and survey patient reported outcomes. As this is a preliminary trial with a small sample, estimates derived will be used to plan the subsequent larger confirmatory trial. Descriptive statistics will characterize the randomized patients completing surveys and outcome assessments. The study will evaluate the primary clinical outcome (BP <140/90 mmHg) 90 days post-discharge as a function of treatment and adjusted for from baseline BP. Change from baseline BP will also be assessed as an outcome. Change in activity level and duration, as well as trends in sedentary time will be compared between arms, and pre- and post-intervention with visual tailored infographics in the intervention arm. Moderating effects of demographics will also be evaluated. Decisions regarding the pursuit of a subsequent trial will use the primary outcome, and analysis of all other measures will be hypothesis generating.

Evaluating the collateral circulation of acute ischemic stroke (AIS) mainly depends on the imaging examination. At present, there is no effective and sensitive biomarker for collateral circulation. Thus, the research objective was to evaluate the predicting role of the CBP/P300-interacting transactivator with Glu/Asp-rich C-terminal domain 2 Ratio (CITED2) from peripheral blood mononuclear cells in the collateral circulation of AIS. We classified the AIS patients into two groups (the good collateral group and the poor collateral group) by DWI-ASPECTS score. The western blot was applied to test the protein expression of vascular endothelial growth factor (VEGF) and CITED2. Then, we collected other clinical data. Binary logistic regression analysis between collateral circulation and clinical data was performed. Finally, Receiver operating characteristic (ROC) curve analysis was used to explore the predictive value of the CITED2.

Despite increasingly effective early treatment strategies for ischemic stroke, post-stroke recovery is often incomplete and depend on spontaneous and therapeutic-induced processes related to neuroplasticity, angiogenesis and reperfusion. These processes are regulated by growth factors, neurotrophines, neurotransmitters, hormones and other factors. This study aims to search biomarkers that prognose brain repair ability and consequently estimate an outcome of stroke patients. The prognostic value of proteins VEGF, IGF-1 and MMP-9 and expression of genes VEGF, IGF-1, MMP-9 is evaluated in association with clinical scales including cognitive assessment scales and depression scales. Blood sample collection as well as scales recording are taken at baseline and 3 weeks later after rehabilitation.

cELVO is a software that has been pre-learned based on a large vessel occlusion diagnosis model using brain CT images, and clinical decision support system for diagnosing large vessel occlusion by automatically analyzing brain CT images by assisting the medical team. The specific aims of this study are to evaluate efficacy of cELVO compared to the sensitivity and specificity levels of medical team to diagnosis with and without cELVO used.
