The primary efficacy objective of the MOST trial is to determine if argatroban (100µg/kg bolus followed by 3µg/kg per minute for 12 hours) or eptifibatide (135µg/kg bolus followed by 0.75µg/kg/min infusion for two hours) results in improved 90-day modified Rankin scores (mRS) as compared with placebo in acute ischemic stroke (AIS) patients treated with 0.9mg/kg IV rt-PA within three hours of symptom onset. Patients may also receive endovascular thrombectomy (ET) per usual care. Time of onset is defined as the last time the patient was last known to be well.
This is a phase one study investigating the safety and efficacy profile of allogeneic cord blood hematopoietic progenitor cells (HPC, Cord Blood), when administered by intravenous infusion and intrathecal injection, in subjects who have sustained an acute ischemic stroke within the past 9 days. Treatment period consisting of 3 sessions of both intravenous infusion and intrathecal injection (or intravenous infusion in conjunction with mannitol for subjects unable to tolerate intrathecal injection). Follow-up phone calls for adverse event (AE) assessment will be conducted at 1 week, 1 month, and 2 months after the first intravenous/intrathecal treatment. A follow up clinic visit at 3 months, 6 months and 12 months will include a neurological exam, MRI, and clinical laboratory tests/urinalysis.
OPTIMISTmain is an investigator-initiated and conducted, international, multicentre, stepped wedge cluster randomized controlled trial comparing the effects of different intensities of nursing care monitoring for patients with acute ischemic stroke of mild severity and without critical care needs after IV-tPA.
The primary objective of this pilot study is the assessment of the safety of the ISS500 System in patients who have experienced an acute ischemic stroke within the anterior circulation. The secondary objectives of this study are to examine the effectiveness of the ISS500 System implantation in the treatment of acute ischemic stroke.
AngongNiuhuang pill has obvious effects on the cardiovascular and cerebrovascular, especially the cerebral vessels. Pharmacological experiments confirmed that AngongNiuhuang pill can protect blood-brain barrier, reduce capillary permeability, improve the tolerance of cerebral ischemia and hypoxia, improve oxidative stress injury, thus protecting brain tissue. Clinical studies have also confirmed that AngongNiuhuang pill can increase the GCS score, reduce coma, improve nerve function defect and promote nerve function recovery. The primary purpose of this trial was to evaluate the effect of AngongNiuhuang pill and placebo on the improvement of life function in patients with ischemic stroke at 90 days in acute phase.
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).
The investigators will be using nocturnal normobaric hyperoxia therapy in patients with diagnoses of conditions related to retinal ischemia.
Placing the head of bed (HOB) at 0-degrees has been shown in small studies to improve blood flow to the brain in patients with ischemic stroke caused by large artery occlusions, thereby reducing stroke symptom worsening. This simple yet potentially impactful intervention has yet to be tested in a large clinical trial in hyperacute large artery ischemic stroke patients, but may provide nurses with a powerful contribution to acute stroke care that is capable of preventing worsening of stroke symptoms and promoting stabilization. Because stroke is the leading cause of preventable long-term disability in adults, this study may show that simple methods such as 0-degree HOB positioning should be considered one of the very first actions taken in the emergent management of acute ischemic stroke patients.
TELECAST-TIA is a prospective single-center study evaluating guideline-based transient ischemic attack (TIA) treatment at an Acute Stroke Ready Hospital (ASRH) pre- and post-initiation of a specialist telestroke inpatient rounding service. TELECAST-TIA will study the following clinical endpoints: diagnostic stroke evaluation, secondary stroke prevention, health screening and evaluation, stroke education, inpatient complications, and stroke recurrence rates. Additional relevant non-clinical data will include patient and provider satisfaction scores, transfer patterns, and a cost analysis.
Remote ischemic conditioning(RIC) is a protective systemic strategy by organs brief and sublethal ischemia to confer protection from subsequent severe ischemia in distant organs, especially for heart and brain. This study will discuss whether RIC can play a part in preventing the patients with coexistence of cerebral and coronary atherosclerosis from the recurrence of cerebral vascular disease(CVD) or coronary artery disease(CAD). This study selects patients who suffered an ischemic stroke within 14 days prior to enrollment. All patients complete cerebral and coronary artery assessment. And then the the investigators select the patients who both have at least one cerebral vascular and at least one coronary artery stenosis over 50%, or the patients who both have at least one cerebral vascular stenosis over 50% and myocardial ischemic events history. These patients will randomly divide into two groups, RIC group and non-RIC group. Non-RIC group will only accept cardio-cerebrovascular disease secondary prevention treatment. RIC group will use not only cardio-cerebrovascular disease secondary prevention treatment, but also RIC everyday for three months, 5 cycles 5min ischemic-5min reperfusion each day. For the first month, the the investigators will call RIC group patients every week for insuring compliance and adverse effect. All patients will follow up endpoint events, cardio-cerebrovascular disease secondary prevention treatment, and the adverse effect every three months, up to one year.
