Filter by:Endovascular therapy is increasingly used for patients with moderate-to-severe acute ischemic stroke.This study will compare the efficacy and safety of RECO(a novel, self-expanding stent retriever) with Solitaire FR within 8 hours of stroke onset caused by the large vessel occlusion.
This study is a non-randomized, Phase 2 clinical trial designed to assess optical cerebral blood flow (CBF) response to bolus normal saline. Subjects will have had an ischemic stroke within 96 hours of enrollment. The study intervention will be a one hour monitoring session. There will be a 15 minute baseline measurement period, followed by intravenous administration of 500cc of 0.9% NaCl over 30 minutes, and finally 15 minutes of monitoring post-bolus. All study measurements will cease after 1 hour. Subjects will be followed during their hospitalization for 7 days or until discharge, whichever is sooner, to monitor for adverse events and to collect clinical information.
The SAMMPRIS suggested that aggressive treatment was superior to intravascular stenting in patients with severe symptomatic intracranial atherosclerotic stenosis (ICAS) due to high complication rate in patients in stenting group. However the intravascular therapy is going on because of low complication rate in considerable Chinese studies coming from several high volume stroke centers. Given to 12.2% patients failing to aggressive medical therap in the SAMMPRIS study, it is imperative to performing an multiple prospective registry study of stenting for patients with ICAS in China.
The objective of this study is to determine the impact of vibratory feedback on the quality and intensity of a common motor rehabilitation task of the upper-arm (hand-to-mouth) in stroke patients. For that purpose the investigators use the SWORD system that combines 3D motion quantification wearable sensors and a vibratory module. The investigators hypothesize that vibratory stimuli during a motor rehabilitation task increase significantly the number of correct movements performed per unit of time. The design of the study is a cross-over randomized clinical trial. With the SWORD system in place each patient will perform the hand-to-mouth task twice (with vibratory feedback and without it), the order being random. The number of correct movements and other motor outcomes will be assessed continuously under both conditions.
The aim of this study is to evaluate the safety of Ginkgolides Meglumine Injection in the treatment of ischemic stroke with Syndrome of Intermingled Phlegm and Blood Stasis.
BACKGROUND: Alteplase dissolves blood vessel clots in acute ischemic stroke and is the only approved acute drug treatment <4½ hours of stroke onset. The overall benefit from alteplase is substantial, but up to 2/3 of patients with large artery clots may not achieve reopening of the vessel and up to 40% of the patients may remain severely disabled or die, leaving substantial room for improvement. Tenecteplase, widely used in coronary heart disease, may be more effective and may have less bleeding complications than alteplase, and may be the drug of choice also in stroke. HYPOTHESIS: Tenecteplase may be given safely to patients with acute ischemic stroke at a dose that is associated with improved clinical outcome compared with existing treatment options. AIMS: To compare efficacy and safety of tenecteplase vs. alteplase given <4½ hours after symptom onset. STUDY ENDPOINTS: The primary study endpoint is excellent clinical outcome at 3 months (effect). Secondary study endpoints are major early clinical improvement (effect) and bleeding complications (safety).
Stroke is a devastating disease. The acute mortality in Sweden is 20 % and 25 % of all patients relapse. Secondary prevention is proven efficient but observational studies have shown that a number of patients are lost to follow up and do not receive recommended prevention. The aim of the study is to 1) describe, by analyzing register data, the detection rate of patients with hospital diagnosis of stroke, TIA, and atrial fibrillation in the primary care center where they are listed. The analysis is done by sex, age, and socioeconomic status. Furthermore, rate of dispensed prescriptions of secondary preventive drugs are analysed for the identified population. 2) in a randomized controlled study evaluate if collegial feed back and targeted information of secondary prevention to the intervention group can improve the detection rate and the medication of the patients listed at the participating primary care centers.
The purpose of this study is to assess the effects in improving life self-care ability of stroke patients after taking Tongxinluo Capsule(within 72 hours after onset) versus Placebos for 90 days.
The purpose of this study is the evaluation and comparison of blood pressure variability indices and ambulatory arterial stiffness index obtained by ambulatory blood pressure monitoring as prognostic indicators in the functional outcome of acute ischemic stroke.
Stroke is the leading case of neurologic swallow dysfunction, or dysphagia. Post stroke dysphagia is associated with approximately 50% increase in the rate of pneumonia diagnoses; aspiration pneumonia is the most common respiratory complication in all stroke deaths, accounting for a three-fold increase in the 30-day post stroke death rate. The long-term goal of this systematic line of research is to decrease the morbidity, mortality, and health care costs associated with disordered airway protection following stroke. The overall hypothesis central to this proposal is that the ability to protect the airway is dependent upon a continuum of multiple behaviors, including swallowing and cough. Safe, efficient swallowing prevents material from entering the larynx and lower airway, and effective cough ejects aspirate or mucus material. Currently, only one end of the continuum, swallowing, is rigorously assessed in stroke patients. However, ineffective or disordered cough is indicative of the inability to eject aspirate material or clear mucus and secretions from the lower airway. Ineffective clearance and subsequent accumulation of material in the lower airway increases the risk of chest infection. Hence, patients at the greatest risk for chest infection would not only have disordered swallowing (dysphagia) but also disordered cough (dystussia), meaning they are more likely to aspirate material and then cannot effectively eject the aspirate from the airway. There is a high likelihood that swallowing and cough are simultaneously disordered following stroke. To date, there is a treatment that targets both swallowing and cough function in stroke patients. Expiratory muscle strength training (EMST) increases expiratory muscle strength (Baker et al., 2005) and there is evidence that supports its use to improve both swallow and cough functions in patients with Parkinson's disease (Troche et al., in press). This cross-system, device-driven approach to rehabilitating multiple contributors to airway protection deficits is highly desirable in the stroke population due to the likelihood of the co-occurrence of both swallow and cough disorders. To date, EMST has not been tested in stroke patients. We propose that by including cough in the screening, evaluation and treatment processes for disorders of airway protection, we will be able to better identify and treat patients most at risk for airway compromise and associated sequelae.
