Filter by:The major aim of this study is to investigate the effects of biofeedback assisted abdominal breathing training on improving the psychological and physiological distress in patients with ACI. In this randomized, controlled, single-blind trial, AIS patients were randomly assigned into experimental and control groups. The experimental group received four HRVBF training sessions. The control group received routine care. Repeated measures of HRV, Mini-Mental Status Examination (MMSE), Hospital Anxiety and Depression Scales (HADS), and Barthel Index for ADLs were collected prior to, and at one, and three months post-intervention.
The Bernese-European RegistrY for ischemic stroke patients treated Outside current guidelines with Neurothrombectomy Devices using the SOLITAIRE™ FR With the Intention For Thrombectomy (BEYOND-SWIFT) is a retrospective, multi-center, non-randomized observational study aims to investigate the safety and efficacy of a Medtronic market-released neurothrombectomy device (applied as initial devices used for intervention) in acute ischemic stroke patients who do not fulfill treatment eligibility according to current guidelines. Patients will be treated or were treated at the discretion of the investigator, independent of participation in this registry. Primary Analysis is the Impact of successful reperfusion on functional outcome at day 90 in patients presenting with large infarct cores (ASPECTS<6) or minor symptoms (NIHSS<8).
The investigators propose to conduct a multicenter randomized trial to test the primary hypothesis of whether early antihypertensive treatment starting between the first 24-48 hours after the onset of an acute ischemic stroke will reduce the risk of composite case-fatality and major disability (modified Rankin Scale score ≥3) at three months compared to delayed antihypertensive treatment (starting on day 8 after stroke onset). In the proposed China Antihypertensive Trial in Acute Ischemic Stroke II (CATIS-2), the investigators will recruit 4,776 patients from 100 hospitals within the China-US Collaborative Stroke Clinical Trial Network. Eligibility criteria for the trial participants include age ≥40 years, acute ischemic stroke confirmed by CT/MRI, symptom onset between 24-48 hours, and average systolic blood pressure (BP) between 140-200 mmHg at randomization. Patients with extracranial or intracranial artery stenosis (≥70%) in both sides or the affected side, NIH Stroke Scale score of ≥21, Glasgow Coma Scale score <8, preceding moderate or severe dependency (modified Rankin scale score 3-5), revascularization, intravenous thrombolytic therapy or mechanical thrombectomy will be excluded. All eligible patients will discontinue their home antihypertensive medications. Patients admitted within 24 hours of symptom onset will require a reevaluation prior to randomization at 24 hours after stroke onset. After randomization, patients in the early treatment group will immediately receive antihypertensive treatment aimed at lowering average systolic BP by 10-20% within the first 24 hours and achieving an average BP <140/90 mmHg within seven days. Patients in the delayed treatment group will discontinue antihypertensive medications for the first seven days. After seven days, both groups will receive antihypertensive treatment with a BP goal of <140/90 mmHg. The primary study endpoint is a composite outcome of death and major disability at three months. The major secondary endpoint will be the first recurrent stroke (hemorrhagic or ischemic) over three-month follow-up after randomization. Other secondary endpoints include ordered 7-level categorical score of the modified Rankin Scale, all-cause mortality, and major vascular events at three months. The proposed study provides 85% statistical power to detect a 15% reduction in the composite outcome of death and major disability over three months at a significance level of 0.05 for a two-sided test. Based on experience from our previous trials, we assumed a 25% event rate of the primary study endpoint and potential loss to follow-up of 5% over three months. The CATIS-2 trial will provide important information for the development of clinical guidelines in the early management of BP among patients with acute ischemic stroke for reducing mortality and major disability.
Today the treatment of ischemic stroke in acute phase is based on medicinal or endovascular revascularization. Cerebral MRI sequences help the diagnostic. This procedure uses deoxyhemoglobin as an endogenous tracer. This is also a scorer of cerebral ischemia and the increase lets visualized transcerebral veins in the suffering zone giving a brush aspect. Several studies show the interest of this sign and conclude that deoxyhemoglobin presence is a predictive factor of cerebral ischemia. The aim of the study is to evaluate this brush-sign and correlate it with the prognosis retrospectively.
Ischemic stroke is accompanied by a three to four hundred percent increase in the brain's extracellular fluid (ECF) and cerebrospinal fluid (CSF) concentration of glutamate, which diffuses and damages surrounding neurons. In this study we tested our hypothesis that blood glutamate levels can be reduced by hemofiltration, resulting in increased extracellular clearance of glutamate and attenuated neurodegeneration, and that decreased blood glutamate levels can provide significant neuroprotection against stroke-associated neurodegeneration, dysfunction and death. Our primary outcome of interest was to assess safety of hemofiltration in acute ischemic stroke patients.
This study aims to identify factors influencing the time span and success of reperfusion after a mechanical thrombectomy in the acute phase of cerebral infarction, and in particular the effect of intra-venous thrombolysis.
The FLOW trial is a randomized placebo-controlled trial analyzing the effect of coupling an anti-depressant, fluoxetine (Prozac), and exercise to improve motor recovery following a stroke.
The investigators hypothesize that earlier initiation of edoxaban in AF-related stroke patients may significantly reduce the early recurrence of ischemic stroke, compared with conventional strategy of anticoagulation following 1-3-6-12 rule. To expedite the verification of the hypothesis, the investigators are planning to use diffusion weighted imaging (DWI), which has been reported to be a surrogate to predict both short-term and long-term prognosis after stroke, to detect the recurrent ischemic events. Because data on the early anticoagulation in patients with AF-related stroke are limited, the investigators decided to perform a pilot study before establishing an appropriate clinical trial protocol. This study will help estimate the efficacy and safety of early administration of edoxaban, and determine the sample size of a following clinical trial. To ensure the safety in this pilot exploration, the investigators will not include patients with severe ischemic strokes, who are often prone to experience hemorrhagic transformation in the acute post-stroke period.
This is a randomized, triple-blind, placebo-controlled, multicenter clinical trial. Eligible patients will be randomized into either the butylphthalide (NBP) or placebo group in a 2:1 ratio.The main purpose of this study is to determine whether butylphthalide can improve dynamic Cerebral Autoregulation (dCA) in large-artery atherosclerosis acute ischemic stroke.
The aim of this study is to evaluate the effect of leg elevation on the prevention of intraoperative hypotension during shoulder surgery in the Beach-chair position. patients undergoing shoulder surgery in the Beach-chair position will be randomly assigned to Group L (with leg elevation) or Group C (no intervention). The primary outcome is the incidence of intraoperative hypotension (mean blood pressure < 60mmHg or systolic blood pressure < 80% of baseline). Secondary outcomes are the incidence of intraoperative cerebral desaturation (cerebral oxygen saturation < 80% of baseline, longer than 30 seconds), total amounts of administered inotropic agents, and systolic blood pressure, heart rate, and cerebral oxygen saturation at various time points.
