Active clinical trials for "Cerebral Infarction"

Stroke is a leading cause of adult disability in the UK. There are few treatment options that improve long-term disability outcomes after stroke. Animal studies indicate that aerobic exercise training can improve brain repair and reduce disability after stroke. However, in clinical practice it is difficult for stroke survivors to undertake aerobic exercise due to lower-limb disability and a lack of accessible exercise equipment. This study will assess the feasibility of implementing a 5-day aerobic exercise training intervention, beginning in the acute phase of stroke (1-7 days post-stroke), using a power-assisted exercise bike. Feasibility outcome measures: recruitment rate (30 participants recruited within 18 months), completeness of data (>80% of planned measurements recorded) and the safety (<10 adverse events related to the intervention) and acceptability (>3/5 comfort scale) of the intervention. We will also investigate the acute effects of aerobic exercise on cerebral blood flow velocity using transcranial Doppler ultrasound, and brain-derived neurotrophic factor (serum and plasma).

The plasma concentration of high-density lipoprotein (HDL) can have anti-inflammatory, anti-oxidative and anti-thrombotic effects in addition to being able to remove cholesterol from peripheral tissues for secretion via the liver. The investigators hypothesise that elevation of plasma HDLs will reduce the inflammatory response following removal of unstable atherosclerotic plaques in the carotid artery. Such plaques can cause strokes and there is great benefit from early surgical removal, however such surgical procedures involve significant risks to the patient. The investigators propose infusing HDL into patients prior to removal of their unstable carotid plaque and measuring the changes in inflammatory responses in comparison to a similar placebo controlled group of patients.

The investigators team had found that the presence of dynamic changes of Clopidogrel resistance are not associated with genetic factors. Currently, study on moderate doses of statins and dynamic Clopidogrel resistance has not been reported, therefore this study will observe 160 cases of open prospective secondary prevention in patients with cerebral infarction. Excluded: those patients occurs Clopidogrel resistance because of slow metabolism caused by cytochrome P450 isoenzyme 2C19（CYP2C19, and then observed the impact of the cytochrome P450 isoenzyme 3A4 （CYP3A4）-metabolized and non-cytochrome P450 isoenzyme 3A4 （CYP3A4）-metabolized statins dynamically on Clopidogrel resistance in the next 9 months, adverse events will be recorded, the metabolite of clopidogrel（H4 ）and the polymorphism of cytochrome P450 isoenzyme 2C19 （CYP2C19）/cytochrome P450 isoenzyme 3A4 （CYP3A4）/ cytochrome P450 isoenzyme 2C9（CYP2C9）will be detected. Expected Result: the patients use the cytochrome P450 isoenzyme 3A4（CYP3A4）-metabolized statins will result in dynamic Clopidogrel resistance easily ,H4 levels will decline, and Clopidogrel resistance is not related to the polymorphism of cytochrome P450 isoenzyme 3A4 （CYP3A4）.

A multicentre, randomised controlled Trial of Exenatide versus standard care in Acute Ischemic Stroke

This study is designed to determine the safety, pharmacokinetics and pharmacodynamics of a single intravenous dose of TS23 in healthy adults.

The main purpose of this trial is to determine whether Xingnaojing, intravenously administered within 24 hours of symptom onset, improves the daily living ability of acute ischemic stroke at 90 days.

Magnesium has a neuroprotective role so the investigators aim to evaluate the role of intravenous magnesium sulphate in improving the clinical outcomes as assessed by the NIH Stroke Scale (NIHSS) in patients with acute ischemic stroke.

The study is a single-arm, open-label, multicenter clinical trial.The primary purpose of this trial is to evaluate the incidence of symptomatic intracranial hemorrhage in patients with acute ischemic stroke within 48 hours after the use of Eptifibatide injection. Patients with acute ischemic stroke treated with intravascular thrombolytic therapy, mechanical thrombolysis, angioplasty and so on were treated with Eptifibatide injection on the first day, followed by the second day, the third day, the discharge day and the 90 days.

This is a randomized, placebo controlled, double-blind phase 3 clinical study to evaluate the efficacy and safety of transcranial ultrasound (TUS) using the Sonolysis Headframe as an adjunctive therapy to intravenous (IV) tissue plasminogen activator (tPA) therapy in subjects with acute ischemic stroke that initially present at non-endovascular (EVT) treating hospitals that have established transport services in place to transfer subjects to hospitals capable of performing EVT.

The main purpose of the study: To evaluate the effect of nitrosone 1 special for patients with acute ischemic cerebral stroke. The secondary purpose of the study: To evaluate the effectiveness of the injection of nitrosone I. T for loyal patients with acute ischemic stroke All women think.
