View clinical trials related to Cerebral Infarction.
Filter by:Cerebral infarcts represent a major cause of morbidity/mortality in spite of therapeutics for a premature recanalisation (intravenous recombinant tissue plasminogen activator (rt-PA) and thrombectomy). Thrombolysis failure by the administration of rt-PA is frequent, in particular in proximal occlusion. Experimental studies suggest that neutrophils could play an important role in the thrombus development via the organization of a network (NET) within the thrombus. Targeting this network of NET could, in addition to the fibrinolysis, increase the rate of recanalisation and thus improve the neurological prognostic after a cerebral infarct. The aim of the research is to Study of the biochemical and histological composition of the stemming thrombi of cerebral thrombectomies with in vitro analysis of the sensibility in the thrombolysis induced by rt-PA +/- Desoxyribonuclease I (DNase I).
The aim of the study is to estimate the contribution of abdominal imaging by magnetic resonance Imaging (MRI) and abdominal scanner in the detection of subdiaphragmatic infarction associated to the atrial fibrillation in the cerebral infarction.
Despite several scientific and technological advances, there is no single neuroprotective treatment that can reverse the brain damage after acute ischemic stroke (AIS). Neuroactive steroids are cholesterol-derived hormones that have the ability to modulate the normal and pathologic nervous system employing genomic and non genomic mechanisms. In this work, we first investigated if AIS affects the plasma concentration of five neuroactive steroids (cortisol, estradiol, progesterone, testosterone and 3-alpha androstenediol glucuronide). Second, we studied if levels of circulating steroids associate with neurological, cognitive and functional outcome in a cohort of 60 to 90 year-old male and female patients with AIS. For this purpose, we recruited patients who were hospitalized at the Emergency Room of the Central Military Hospital within the first 24 hours after stroke onset. We designed two experimental groups, each one composed of 30 control subjects and 30 AIS patients, both males and females. The assessment of neurological deficit was performed with the NIHSS and the tests used for the functional and cognitive status were: (1) modified Rankin Scale; (2) Photo test and (3) abbreviated Pfeiffer's mental status questionnaire.
The investigators design a randomized, control study to evaluate the therapeutic effect of scalp acupuncture using Jiao's motor area for motor dysfunction in ischemic stroke patients using the following outcomes: motor function, activity of daily living,quality of life.
The risk of early recurrence or progression of acute ischemic stroke is very high, even in patients treated with aspirin. The Chance study show that clopidogrel plus aspirin treatment reduced the risk of recurrent stroke in patients with transient ischemic attack (TIA) or minor ischemic stroke (NIHSS ≤ 3) within 24 hour onset and was not associated with increased hemorrhage events, compared with aspirin monotherapy. However, it is not known whether the dual antiplatelet treatment could reduce the risk of early recurrence or progression in patients with acute mild to moderate ischemic stroke (4 ≤ NIHSS ≤ 10). The investigators hypothesise that clopidogrel-aspirin treatment will be superior to aspirin monotherapy in this group of patients.
The aim of this study is to show for the first time that treatment with intravenous fibrinolysis using rt-PA in patients with recent ischemic stroke is accompanied by increases in circulating levels of BDNF, which may reflect an increase in BDNF synthesis in the brain. The analysis of the recovery of functional and cognitive abilities as well as mood at 3 months will allow us to study the impact of BDNF on these parameters. Thus, depending on the results obtained, circulating BDNF could serve as an early marker of these.
The current management of ischemic stroke is based on different strategies that may be combined: intravenous thrombolysis in a stroke ICU, intravenous thrombolysis in a telemedicine procedure, endovascular thrombectomy. Given this now rich therapeutic arsenal, it seems necessary to evaluate practices in local care in the field and the impact of these on the prognosis of ischemic stroke victims. The aim of this observational study is to compare these different care practices without interfering with the choice of strategy. A blood sample will also be taken at different times to study the value of growth differentiation factors (GDF) 8, 11 and 15, and Brain-derived Neurotrophic Factor as prognostic biomarkers
Stroke is one of the leading causes of death and disability in China. Intravenous thrombolysis with recombinant tissue plasminogen activator (rtPA) improves the outcome for ischemic stroke patients who can be treated within 4.5 hours of symptom onset. In China, in addition to rt-PA, intravenous urokinase within 6 h has also been recommended by the 2010 Chinese Guidelines for the Diagnosis and Treatment of Patients with Acute Ischemic Stroke, and supported by evidence from two intravenous urokinase thrombolysis trials. Urokinase is used more frequently than rt-PA, mainly because it is cheaper. To describe Chinese experience with thrombolytic therapy for Ischemic Stroke within 4.5h onset, we designed a multicenter, prospective, registry study. The aim of INtravenous Thrombolysis REgistry for Chinese Ischemic Stroke within 4.5 h onset（INTRECIS）was to assess the safety and efficacy of intravenous rtPA, urokinase as thrombolytic therapy within the first 4.5 h of onset of acute ischaemic stroke.
This research is primary to compare effectiveness of scalp electroacupuncture and scalp acupuncture on motor function of the upper limb(UL) in convalescence phase of ischemic stroke. The clinical research is a randomized controlled trial (RCT),consisting of two arms of scalp electroacupuncture group and sham sclp electroacupuncture group to value difference of upper limb function after 4 weeks. The result indicates that scalp electroacupuncture is more sufficient to alter function. The purpose is to value effectiveness of scalp electroacupuncture on motor function of the upper limb in convalescence phase of ischemic stroke.
The first purpose of this study is to find out the clinical benefit and risk of oral aspirin for unruptured intracranial aneurysm (small than 7mm) combined with cerebral ischemia in patients in the real world. The second purpose of this study is to get the prediction model of aneurysm's rupture in patients who has unruptured intracranial aneurysm (small than 7mm) combined with cerebral ischemia , and find out who is suitable for oral aspirin.
