Active clinical trials for "Cerebral Infarction"

An open-label, prospective, observational, multicenter study. The study enrolls adult outpatients with CCI from 8 federal districts of the Russian Federation.

The hypothesis of this study is that "the poor metabolizer or intermediate metabolizer of the cytochrome P450 2C19 genotype in patients with acute ischemic stroke is associated with increased risk of composite cardiovascular events (recurrent stroke, myocardial infarction, cardiovascular death) compared to those who of extensive metabolizer of the cytochrome P450 2C19 genotype".

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.

In non-acute symptomatic ischemic stroke, the decision-making of medical treatment plus intracranial stenting has been more and more popular, especially in patients with intracranial large severe stenosis or occlusive artery. Nonetheless, there is no evidence from randomized controlled trials evaluating the efficacy of this treatment after the Wingspan Stent System Post Market Surveillance (WEAVE) and Wingspan One Year Vascular Imaging Events and Neurologic Outcomes (WOVEN) trial compared with medical treatment alone. This trial was to investigate whether medical treatment plus intracranial stenting would prevent the recurrent ischemic stroke in the territory of the symptomatic intracranial artery during 1-year follow-up.

The 4-meter walk test and 10-meter walk test is currently applied to assess gait speed.These tools are frequently used in clinical trials and were also shown to be reliable measurement methods. There are ocassions where it is not possible to have a long corridor to measure gait speed. It is necessary to have a tool to evaluate gait speed in a small space as 4-meter walk test.

Stroke is accompanied by local inflammatory response and systemic immunosuppression. Immunosuppression markers are associated with the occurrence of medical complications (infections), whereas inflammatory markers are associated with worse functional prognosis. This prospective study tries to validate in acute stroke patients the prognostic usefulness of a panel of immune biomarkers that have previously been associated with various clinical outcomes. The identification of beneficial and harmful immune responses in cerebral ischemia will allow the prediction of the clinical course of the patients and will be helpful in designing immunomodulatory therapeutic strategies for acute stroke.

This is a Post Marketing Observational Study of cilostazol (Pletaal® SR capsule). As this study is observational in nature to collect the safety data after administrating the Pletaal SR capsule, from baseline to 16 weeks.

Stroke remains the leading cause of disability in the United States. An estimated 40-50% of all ischemic strokes are caused by large-vessel occlusion of a major cerebral artery (LVO). However, in some cases, the occlusion results in mild symptoms, at least initially, and these patients frequently do not receive any treatment. These strokes, however, may result in unfavorable long-term outcomes despite relatively benign initial course. Recent large randomized studies in patients with severe stroke symptoms and associated LVO showed efficacy and safety of endovascular mechanical thrombectomy, but patients with mild symptoms were not specifically addressed. Based on the investigators' own data and limited evidence in the literature, the investigators propose that early mechanical thrombectomy in patients with LVO associated with mild stroke symptoms (defined as NIHSS ≤ 5) is safe, and results in favorable long-term patient outcomes. The objective of this prospective pilot study is to assess the safety and outcomes of mechanical thrombectomy in patients presenting with acute ischemic stroke due to a large vessel occlusion in the anterior or posterior circulation under 24 hours with mild symptoms (NIHSS ≤ 5).

This clinical trail will evaluate the effect of Sanchitongshu combined with antiplatelet drugs (Aspirin or Clopidogrel) in the treatment of high-risk ischemic stroke patients in adults. Half of participants will receive SanchiTongshu and one of antiplatelet drugs (Aspirin or Clopidogrel) in combination, while the other half will receive a placebo and one of antiplatelet drugs (Aspirin or Clopidogrel).

Objective: To explore the effectiveness of raising serum nao granules in reducing the risk of bleeding in patients with acute ischemic stroke treated with intravenous thrombolysis in the real world
