Active clinical trials for "Ischemic Stroke"

The availability of several high-cost strategies for the prevention of cardiovascular morbidity and mortality in patients with established cardiovascular disease highlights the necessity of reliable risk stratification of these patients. Several such prognostic models are available for patients with coronary artery disease; however, for patients with ischemic stroke, the available risk stratification schemes are very few and have several limitations. This study aims to develop a prognostication tool to stratify the risk of cardiovascular outcomes in patients with ischemic stroke. The development of a well-designed prognostication tool for the stratification of cardiovascular risk in patients with ischemic stroke may assist to the identification of the highest-risk patients and hence, provide useful information to clinicians and authoritative bodies when prioritizing high-cost strategies for secondary stroke prevention.

The purpose of this study is to evaluate recanalization treatments use, safety and efficacy at the acute phase of arterial ischemic stroke in pediatric patients

Optimizing the MRI protocol in acute ischemic stroke remains a challenging issue. In this field, susceptibility-weighted sequences have proved their superiority over T2. Besides the strengthened susceptibility effect, enhanced susceptibility-weighted angiography (eSWAN) sequence provides also a time-of-flight (TOF) effect, allowing the exploration of the intracranial arterial circulation. The objective of this study is to compare eSWAN and 3D TOF, considered as the reference, in the detection of arterial occlusion in acute stroke.

Investigators aim to study effectiveness of systemic thrombolytic therapy on acute ischemic stroke patients with near infrared spectroscopy.

The purpose of the research is to use plasma free fatty acid profiling as a biomarker for ischemic stroke. The plasma free acid profile will be specifically and significantly changed in early stages upon stroke onset, and correlate with the stroke volume and progression determined by imaging techniques.

In order to bridge the great gaps, Chinese Stroke Association (CSA) and American Heart Association (AHA) sought to develop, conduct, and assess a multifaceted quality improvement intervention to increase the adherent rate of IV tPA and ET and improve 3-month clinical outcomes for these patients through our cluster-randomized stepped-wedge IMPROVE: Stroke in China trial.

The primary goal of the PRAISE study is to develop a diagnostic algorithm that allows the prediction of acute coronary syndrome in stroke patients with elevated levels of cardiac troponin.

Post stroke aphasia (PSA) is one of the most frequently happened deficiency of stoke, affecting speaking,comprehension, writing and reading of language. Generally, PSA is commonly seen in cortical damage, but in recent years it has been found that subcortical injury is also an important cause of PSA, which is called subcortical aphasia. Using fMRI technology, the investigators aim to investigate the language function of patients with subcortical cerebral infarction at different stages of recovery , and explored the mechanism of post-injury language reorganization in the brain. The investigators recruited 60 first-episode acute cerebral infarction patients with one-side lesion in subcortical white matter (40 with left injury and 20with right injury) and 20 health volunteers. All participants are right-handed, and screened with MMSE, HAMD and HAMA to exclude cases of psychosis, post-stroke dementia and depression. Each participant was arranged to have three test sessions at different stages after the infarction (T1:within 3 days after onset of the stroke ; T2:28 ±3days after onset; T3: 90±3days after onset), with fMRI and Western aphasia battery (WAB) in each session. The purpose of this study is to explore the pathogenesis of subcortical aphasia, and to understand the dynamic reorganization of language network during the recovery of language function.

The purpose of the Trevo® Retriever Registry is to collect real world performance data of the Trevo Retriever which is intended to restore blood flow in the neurovasculature by removing thrombus in patients experiencing ischemic stroke.

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.
