Active clinical trials for "Cerebral Infarction"

Although there has been increasing interest in the association between cancer and cerebrovascular disease, the underlying pathophysiology of stroke in cancer patients is still not fully understood. The aim of this study is to investigate the stroke mechanisms in patients with cancer-associated stroke.

The purpose of this study is to measure cerebral oxygenation and cardiac output of total shoulder replacement patients undergoing general anesthesia (GA) and positive-pressure ventilation (PPV). We hypothesize that cerebral desaturation occurs frequently during GA with PPV, but is rare during GA and spontaneous ventilation. We also hypothesize that cardiac output usually is well maintained under GA in the sitting position when epinephrine is used, but that decreased cardiac output increases the risk of cerebral desaturation.

This cohort study will evaluate the relatiobship of stroke recurrence and anti-platelet resistance in ischemic stroke patients

The aim of this study was to determine the prevalence rate and risk factors for chemical laboratory clopidogrel low-response (CLR) in the acute phase after an ischemic stroke.

The purpose of this study is to evaluate the utility of the S-STREAM as an instrument to assess motor function in subjects who have experienced a nonhemorrhagic ischemic stroke.

Post-Market Registry on Use of Merci Retrieval System. Primary data to be collected will include: Post-procedure revascularization success 90-day mRS 0-2 90-day mortality

Using patients receiving spinal anesthesia as a model to evaluate the treshold value of cerebral oximeter to detect the symptoms of cerebral ischemia

Introduction For several years "ischemic" electrocardiographic (ECG) changes in the acute phase of ischemic stroke have been reported. Whether these ECG changes reflect true myocardial ischemia remains controversial. So far no study has assessed different markers of myocardial ischemia or necrosis in consecutive patients admitted to hospital with an acute ischemic stroke. Purpose The main purpose of this study is to determine the potential burden of reversible and irreversible myocardial ischemia in patients with an acute ischemic stroke. Patients and methods Serial blood samples for measuring troponin T, CK-MB and NT-proBNP are collected in 250 patients with evidence of an acute ischemic stroke admitted to the Department of Neurology at Odense University Hospital. In addition resting 12-lead ECG recordings will be obtained on a daily basis, and a 24-hour ST-segment ambulatory monitoring will be performed once within the first week of hospitalisation. Finally, myocardial perfusion patterns during rest will be evaluated by means of a myocardial perfusion scintigraphy in patients with an elevated troponin T level. Six months later control measurements of troponin T, CK-MB and NT-proBNP and a 12-lead ECG will be obtained. Expectations The study will contribute with original observations in patients with acute ischemic stroke considering the following issues: The prevalence and characteristics of ECG changes suggestive of myocardial ischemia. The prevalence of transient ST-segment changes on ambulatory monitoring. The prevalence and degree of myocardial necrosis as judged from biochemical markers. The prevalence of reversible and irreversible perfusion defects on myocardial scintigraphy. The prevalence, size and patterns of NT-proBNP. Whether there is a change in ECG and biochemical markers over a 6-month follow-up period. The results may have clinical implications regarding early and late treatment as well as clinical follow-up of patients recovering from an episode of acute ischemic stroke.

The aim of this study is to assess the use of ASPECTS and stroke biomarkers to predict the outcome and cognitive impairment in acute ischemic stroke.

Background: Hyperglycemia is encountered in 20% to 40% of acute stroke patients, with or without a pre-morbid diagnosis of diabetes mellitus. Hyperglycemia is a risk factor for infarct expansion and poor outcome through the first 72 hours of onset in both diabetics and non-diabetics patients. This study was done to evaluate the glycemic status after acute ischemic stroke and assess its rule in influencing stroke outcome as regards the duration of hospital stay, motor deficit and mortality. Methods: This retrospective study was conducted in Elzaiton specialized hospital from June 2016 to June 2017on 80 patients after approval of local medical ethical committee. Patients with acute ischemic stroke without other major comorbidities within 24 hours of onset of symptoms were included and divided into two groups, controlled group (Random blood suger not more than 150 mg/dl) and uncontrolled group ( Random blood suger more than 150 mg/dl). All patients were evaluated for GCS as a primary outcome and for hemorrhagic transformation, hospital stay duration, mechanical ventilation, need for vasopressors,hospital stay and mortality as secondary outcomes.
