Active clinical trials for "Ischemic Stroke"

To evaluate the performance of patent foramen ovale (PFO) device developed by Lifetech Technology (Shenzhen) Co., LTD

Paroxysmal atrial fibrillation is often undetected because characteristics such as short duration, episodic, and frequently asymptomatic nature make it challenging to diagnose at the bedside, leading to suboptimal secondary prevention. It is not uncommon for paroxysmal atrial fibrillation to be undetected in a single electrocardiogram (ECG) on admission. Conventional 24-hour Holter monitoring is often used to detect paroxysmal atrial fibrillation. However, systematic review suggests Holter monitoring will identify atrial fibrillation in only an additional 4.6% of patients, no better than detection rates observed in groups lacking routine monitoring. On the other hand, for ischemic stroke patients with sinus rhythm at baseline but paroxysmal atrial fibrillation still suspected, no recommendation beyond repeated 12-lead ECGs is made in the United Kingdom guideline. Serial 12-lead ECG has been used to detect possible paroxysmal atrial fibrillation among acute ischemic stroke patients and found 15 new cases of atrial fibrillation in 133 acute ischemic stroke patients (11.3%) without atrial fibrillation at baseline. The optimal investigation strategy, including modality, duration of investigation, and patient subgroup remains undefined, not only for efficacy in the detection of atrial fibrillation, but also cost-effectiveness in healthcare systems. The objective of this project is to conduct a pragmatic multicenter randomized controlled trial for the comparison of serial 12-lead ECG once daily for 5 days and 24-hour Holter to detect paroxysmal atrial fibrillation in acute ischemic stroke patients without atrial fibrillation identified by baseline ECG or history.

Arterial ischemic stroke (AIS) is a devastating condition, affecting 1.6-5/100,000 children/year. Although their outcome is different, children with stroke do not recover better than adults, with at least 2/3 suffering long term sequels such as developmental (motor, global intellectual, language...) and behavioral disabilities, epilepsy, and low adaptative and academic skills... Stenotic cerebral arteriopathy is identified as AIS etiology in 60-80% of previously healthy children and the course of this arteriopathy is the strongest predictor of recurrent events. 30-40% of these children have a focal unilateral cerebral arteriopathy (FCA). Childhood FCA is suspected to be an inflammatory vessel wall pathology triggered by varicella and other (viral) infections. As recurrences occur for the great majority in the first 6 months after the index event, aspirin 5 mg/kg/day is recommended for at least 18 months to 2 years. As there is a rational for using immunomodulatory drugs at the acute stage of FCA, immunotherapies are currently used by neuropaediatricians in AIS, mainly as steroids for children with stenosing arteriopathies. However, due to weak evidences, the literature cannot either encourage or discourage this practice. The long term course of children with FCA is only approach to date by retrospective studies and controversies about outcome remain (for example, the recurrence risk on antithrombotic treatment varies notably from quasi zero to 25%). And finally, it is shown in childhood stroke, as well as in the global field of longstanding impairment, that parental and medical points of view do not match consistently. Longitudinal studies are needed to deserve this familial approach.

The Belgian Stroke Council initiated a project to improve risk factor control and medication adherence in ischemic stroke patients by developing an individualized in-hospital initiated and post- discharge, digital coaching program addition to standard practice (strokecoach.be).

The brain is able to change throughout life in response to learning, or injury, or to adapt to changes in the environment, which is known as neuroplasticity. Stroke survivors suffer disabling chronic motor impairments that have proven challenging to improve. Increasing neuroplasticity using selective serotonin reuptake inhibitors (SSRIs) is a promising approach to promote motor recovery in patients with stroke.

The investigators conduct this study to investigate whether oral administration of Dimethyl Fumarate, a Food and Drug Administration-approved drug for multiple sclerosis, is safe and effective in combination with intraarterial treatment in patients with Acute Ischemic Stroke.

The primary objective of the study is to compare the effect of 90-day treatment with ticagrelor (180 mg [two 90 mg tablets] loading dose on Day 1 followed by 90 mg twice daily maintenance dose for the remainder of the study) vs acetylsalicylic acid (ASA)-aspirin (300 mg [three 100 mg tablets] loading dose on Day 1 followed by 100 mg once daily maintenance dose for the remainder of the study) for the prevention of major vascular events (composite of stroke, myocardial infarction [MI], and death) in patients with acute ischaemic stroke or transient ischaemic attack (TIA).

Currently, thrombolysis is offered to less than 1% of patients in low to middle income countries (LMICs) where access to health care is often based on the financial capabilities of the patient. There is therefore an urgent need for an effective but affordable alternative thrombolytic agent. Streptokinase (SK) ($35) is much more economically feasible as opposed to tissue plasminogen activator (tPA) ($2800). In this study, we propose a reevaluation of the use of streptokinase (SK) in the treatment of acute ischemic stroke. We want to emphasize that we will only consider this as a 'treatment option' if we are absolutely certain that IV tissue plasminogen activator (tPA) will not be offered to the patient due to its high cost. It is hypothesized that treatment with SK in appropriately selected patients will be associated with a hemorrhagic transformation rate similar to that of tPA.

In order to observe the secondary preventive effect of the Dengzhanshengmai capsule on ischemic stroke, the investigators hold the large randomized control trial (RCT). 3143 subjects are included in 83 clinical research centers all over China. The subjects are randomly grouped into two groups. The basic therapy included antiplatelet aggregation, stroke health education, management of blood pressure, blood lipid and blood glucose, etc. The treating group will take the compound Chinese Medicine Deng Zhan Sheng Mai capsule and the contrast group will take the placebo for twelve months. Then all of the subjects are visited on the 30th, 90th, 180th, 360th day after inclusion. The recurrence of stroke, cardiovascular events, and peripheral arterial events are observed.

A patent foramen ovale (PFO) is found more frequently in patients with an ischemic stroke than in control subjects. Therapeutic options to prevent stroke recurrence include antiplatelet drugs, oral anticoagulants, and transcatheter closure of the foramen. However, there are no published studies showing convincingly the superiority of any one of these strategies in preventing stroke recurrence. The aim of this randomized clinical trial is to assess whether chronic anticoagulation on the one hand and transcatheter on the other hand are superior to chronic antiplatelet therapy in preventing stroke recurrence.
