Filter by:Having a transient ischemic attack (TIA) or a minor stroke is a real risk factor not only for early recurrent stroke but also for major extracranial vascular events. Despite these warning events provide an opportunity for prevention usual post-discharge care of these subjects (mainly at primary care) is not associated with an optimal control of cerebrovascular risk factors (CRF). The investigators hypothesized that patients exposed to the intensified integrated multifactorial interventional care program (ICP) model would exhibit better management of CRF and receive more targeted advice than patients receiving standard care. A second objective was to investigate the effect of the ICP model on stroke recurrence or the appearance of major extracranial vascular events. To test this hypothesis the investigators perform a controlled, randomized, single blind, parallel trial. Subjects are recruited at the Stroke Unit and are randomized into two groups: 1. usual care (control group) and 2. ICP (intervention group). Patients assigned to receive usual care (general practitioner with the possibility of being referred to specialists) are compared to those assigned to undergo ICP. This ICP involves strict treatment goals (LDL-cholesterol <100 mg/dl, blood pressure <130/80 mmHg, HbA1c<7%, no smoking, regular exercise and no excessive alcohol consumption) to be achieved through behavior modification (diet, physical activity, smoking cessation, alcohol cessation) and a stepwise introduction of pharmacologic therapy for the main CRF (hypercholesterolemia, hypertension and diabetes). This multifactorial intervention is overseen in each primary care center by a trained general practitioner and nursery. The treatment goals are the same for the control group and the intervention group. General practitioners caring patients of each group are informed of these strict treatment goals. Patients in the ICP group receive a minimum of four scheduled individual consultations in one year (baseline, 3, 6 and 9 months). Primary and secondary outcomes are evaluated by an external Neurologist at 12 months after their inclusion.
The study was designed as a multicenter multiracial prospective observational study of acute ischemic stroke and TIA patients across china. The purpose of this study is to determine the monogenic disorders incidence of Chinese early-onset stroke patients. We plan to consecutively enroll more than 500 patients with early-onset stroke(in the 18- to 45-year age range) admitted in stroke units within 7 days after symptoms onset in participating centers. These early－onset stroke patients are referred for targeted sequencing using 'cerebrovascular disease panel'. By analyzing the sequencing results, we intend to identify monogenic causes causing early－onset stroke and develop clinical algorithms that might assist the clinician in deciding in which early－onset stroke patients testing for monogenic causes of stroke.
Study Design: This is an investigator-initiated prospective, open label, single arm phase IV study. Patients with documented non-valvular atrial fibrillation (AF) with acute TIA (defined as acute focal neurological deficits, with complete resolution of symptoms within 24 h of onset) or ischemic stroke, irrespective of infarct volume or clinical severity will be enrolled. Study Aim and Objectives: The overall aim of this study is to demonstrate the feasibility and safety of initiating apixaban therapy within 14 days of TIA or ischemic stroke regardless of the size and severity in patients with AF. Investigators will systematically assess prospectively collected CT scan images for evidence of HT and re-infarction.
The project is a 6-month prospective Randomized Controlled Trial evaluating the effects of TargEted MAnageMent Intervention (TEAM, N=80) vs. wait-list (WL, N=80) control in African American men who have experienced a stroke or TIA within the past 5 years.
Preclinical research has established a convincing connection between changes in the gut microbiota composition and stroke outcome. However clinical data on the gut-brain axis, and its chronic characteristics, is sparse. Additional investigations in the context of ischemic stroke regarding the relationship between dysbiosis and functional changes of the microbiome, as characterized by the metabolome, are still required. The StrokeMicroBiomics study will offer insight into these mechanisms and offer new potential targets for therapeutic interventions. The primary objective is the characterisation of gut dysbiosis in ischemic stroke patients in the acute phase after stroke and during a 3 month follow-up period. The secondary objectives include the identification of dysregulated gut microbiome metabolites and key immune cell populations in addition to the clinical progression of the study participants during the 3 month follow-up period after disease onset.
Intracranial atherosclerosis (ICAS) is the most common cause of stroke worldwide. It carries a worse prognosis than other stroke etiologies, with an annual rate of recurrent stroke and death of 15% despite intensive medical management, and as high as 35% in certain populations. Overall, treatment and prevention of stroke due to ICAS has been unsuccessful. While two recent clinical trials have shown modest improvement in the efficacy of intensive medical treatment, these trials were terminated early given the elevated rate of complications, stroke, and death in the interventional arms. In fact, intensive medical management appears to reduce the risk of embolism; however, medical management alone does not address the progression of intracranial arterial stenosis or the pathophysiologic components of hypoperfusion and poor collateral circulation. Levels and types of various angiogenic factors in the blood and tissues have been proposed to be predictive of patient outcome after ischemic stroke and treatment for stroke. This study therefore pursues a new paradigm to investigate responses to ICAS treatment from the perspective of cerebral collateral vessel generation and the role of angiogenic factors. Specifically, pro- and anti-angiogenic factors in patients with ICAS are evaluated at baseline and longitudinally in response to both medical and surgical treatment. For this we have developed methodologies for the isolation and measurement of these growth factors in plasma of patients with ICAS. These methodologies will enable us to obtain a detailed understanding of the variation and dynamic properties of local and circulating angiogenic factors over time in response to medical and surgical treatment, and their association to outcome phenotypes. This analysis is complemented by studies of angiographic development of neovascularization. If successful, this study will help to better understand the role of angiogenesis in ICAS and create a foundation from which to explore therapeutic treatments for ICAS which harness the natural processes of angiogenesis.
This study evaluates the feasibility and effectiveness of an oropharyngeal exercise (O-PE) regimen in treating post-stroke obstructive sleep apnea, as an alternative therapy to continuous positive airway pressure (CPAP). Eligible patients will be randomized (1:1) to treatment using a pre-specified schedule of O-PEs vs. a sham control arm.
An extracranial-to-intracranial (EC-IC) revascularization is the most widely used treatment to improve cerebral perfusion in patients with moyamoya disease (MMD), and it has been shown to reduce the risk of subsequent stroke and neurological deficit. However, perioperative changes in cerebral hemodynamics can induce fluctuations in cerebral perfusion that may lead to transient or irreversible neurological deficits. Our preliminary single-center study suggests that postoperative intravenous administration of dl-3-n-butylphthalide (NBP) may alleviate perioperative neurological deficits and improve the neurological outcomes after EC-IC revascularization for MMD. This is a multicenter, randomized, double-blind, single-controlled, add-on to standard of care study of NBP in patients with MMD of high risk for ischemic cerebrovascular events after EC-IC revascularization surgery.
The purpose of this study is to establish a methodological framework based on existing advanced neuroimaging technologies as a new clinical neuroimaging tool for assessment of possible affected brain connections in stroke and TIA patients. Thus, providing new insights into microstructural changes that may underline why those patients experience deficits like fatigue.
wide range of diagnoses may present like stroke, called stroke mimics as well as transient ischemic attacks .
