Active clinical trials for "Ischemic Stroke"

Ischemic stroke has a variety of treatments and currently drug therapy is one of the main treatments.A number of clinical studies have proved that alprostadil (PGE1) has pharmacological effects of significant dilation of blood vessels, inhibition of plate aggregation, anti-atherosclerosis and increased cerebral blood flow.Evaluate the 90-days efficacy by comparing two groups of patients'(one with alprostadil,another with placebo) mRS.

SEACOAST 1 is a prospective, randomized, blinded endpoint trial comparing collateral vigor and clinical outcomes, with different forms of GA in patients with acute ischemic stroke due to anterior circulation large vessel occlusion (LVO) undergoing mechanical thrombectomy. The study compares GA with normocarbia (GAN) versus GA with mild hypercarbia (GAH), with a primary outcome of collateral robustness at measured at catheter angiography and clinical efficacy as secondary outcome. It is anticipated that the SEACOAST 1 will be followed by a larger, pivotal trial, SEACOAST 2, with primary clinical endpoints, in which the best method of GA identified in SEACOAST 1 is compared with the alternative strategy of anesthesia care (MAC) with minimal or no sedation. The current study focuses uppn SEACOAST 1, which is to be conducted in University of California, Los Angeles Ronald Reagan Medical Center and Santa Monica Medical Center. All acute stroke patients who arrive to one of these two stroke centers and are deemed eligible for thrombectomy will be considered for the proposed study. Physician-investigators will determine study eligibility. Informed consent to participate in the study will be obtained from legally authorized representatives or competent patients. For non-competent patients without on-scene legally authorize representatives, the consent process will utilize enrollment in emergency circumstances with exemption of informed consent (EFIC).

In this trial, The investigators are going to investigate the improvement of neurological functions and infarced area of the brain in ischemic stroke patients after ingestion of omega 3 products that have high concentrations of DHA and EPA in comparison to control group. The study will assess the improvement by computerized calculation of the size of the infarcted area before and after the intervention and neurological assessment tools. The researchers will follow the scientific and ethical regulations prevent any harmful effect on recruited subjects.

The aim is to assess the effects and harms of Xueshuantong lyophilized powder versus placebo in patients with acute ischemic stroke when initiated within 72 hours of symptom onset.

The main purpose of this trial is to evaluate the efficacy and safety of Buqitongluo Granule in treating qi deficiency and blood stasis syndrome, and explore the effect of the improvement of qi deficiency and blood stasis syndrome on the prognosis of diseases.

Non-invasive brain stimulation (tDCS) such as transcranial direct current stimulation (TDCS) has been reported to be effective in improving motor performance and safe in participants with cerebral infarction. However, few studies have been done in participants with acute cerebral infarction. In this study, the investigators want to see the effect of tDCS in acute cerebral infarction. the investigators perform tDCS in participants with acute ischemic stroke within 48 hours after stroke onset and the investigators measure motor weakness and function at early phase as well as at 3 months.

The investigators have previous shown that regional hypothermia by the intra-arterial infusion of cold saline combined with mechanical thrombectomy in acute ischemic stroke is feasible and safe. The safety of selective brain cooling in patients undergoing mechanical thrombectomy, however, is not established in a randomized trial. The investigators therefore conducted this RCT study to further explore the safety of regional hypothermia in patients with acute ischemic stroke who underwent mechanical thrombectomy.

Ischemic strokes account for more than 80% of strokes. Ischemic strokes are caused by the occlusion of an intracranial artery by a thrombus, responsible for tissue ischemia related to a decrease in local cerebral blood flow (CBS). Thus, the management of patients with Ischemic strokes is based on the preservation of an area that maintains sufficient intracranial hemodynamics (IH) and achieves the fastest possible recanalization. The impact of the patient's position (supine or seated position) on the IH in the event of narrowing or occlusion of an artery is poorly assessed but may be of particular importance. In practice, variations in blood flow according to the positioning of the patient's body can be measured using a transcranial Doppler. It is a simple, non-invasive and painless examination that provides the patient's bed with data on the intracerebral hemodynamic profile of patients. This study was implemented because there are no studies known to us that evaluate the effect of verticalization on intracerebral hemodynamics based on the presence of upstream arterial stenosis or occlusion and other multimodal evaluation data in transcranial Doppler.

Stroke is the third most common cause of death worldwide and the leading cause of disability. High blood pressure is an important risk factor for stroke. Lowering a person's blood pressure reduces the risk of future stroke or heart attack. However, the optimal target blood pressure after a person suffers a stroke is not known. This is a study designed to establish the feasibility of a larger clinical trial, the aim of which will be to find out if greater blood pressure lowering is safe and effective for patients who suffer a stroke.

This observational, prospective cohort, pilot study aims at investigating usability, operational, and economical factors around 'traditional' and 'technology-supported' approaches to promote a healthy life-style in stroke survivors, after discharge from an in-patient clinic. The investigators primary objective is to evaluate the adherence to prescribed behavioral changes in dieting and exercising up to one year after clinical discharge. This pilot study will follow and document the observations of two groups of patients, one offered a 'traditional' and another one a 'technology-supported' approach by the healthcare provider. The investigators secondary objective is to gain insights on how to efficiently (and securely) facilitate remote counselling once patients get discharged from the clinic.
