Active clinical trials for "Ischemic Stroke"

To determine the safety and efficacy of in situ ischemic postconditioning immediately after successful reperfusion in AIS patients underwnet EVT.

Safe and effective severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines may reduce the transmission of and achieve population immunity against the COVID-19 pandemic, which accounted for more than 3.75million deaths worldwide. With World Health Organization's (WHO) effort on ensuring equitable access to COVID-19 vaccines, vaccination rate may increase in the near future. On the other hand, vaccination hesitancy has emerged as a major hindrance on the global vaccination campaigns in certain areas due to safety concerns, social factors, and public health policies. For instance, a recent survey conducted in Hong Kong showed a low vaccine acceptance rate of 37%. Long-term safety concerns and post-vaccination events relayed by the social media maybe reasons for vaccination hesitancy. Among which, cerebrovascular accidents (CVA) after vaccination were one of the most frequently reported post-vaccination events. These reports ranged from ischemic strokes in elderly patients with multiple cardiovascular co-morbidities, to hemorrhage strokes in otherwise "young-and-fit" adults. While many of these events were investigated by the COVID-19 immunization expert committee, an important premise to address the apprehension of CVA after vaccination is the provision of evidence-based information of the impact of COVID-19 vaccines on brain health. In this prospective, longitudinal, observational study, we aim to elucidate the relationship between COVID-19 vaccines and cerebrovascular health in healthy citizens in a population-based cohort.

Edaravone dexborneol, comprised of 2 active ingredients, edaravone and (+)-borneol, has been developed as a novel neuroprotective agent with synergistic effects of antioxidant and anti-inflammatory in animal models. The TASTE trial (Treatment of Acute Ischemic Stroke with Edaravone Dexborneol) administered edaravone dexborneol or edaravone alone to stroke patients within 48 hours after stroke onset, finding that 90-d functional outcome was better in edaravone dexborneol group. However, the TASTE trial excluded patients undergoing reperfusion therapy (i.e., intravenous thrombolysis and mechanical thrombectomy). Therefore, the investigators aim to evaluate the efficacy of edaravone dexborneol in addition to mechanical thrombectomy in the treatment of acute ischemic stoke.

Stroke is the second leading cause of death and one of the main contributors to disability. Patients who survive the acute phase of ischemic stroke and those with transient ischemic attack (TIA) are at high risk of subsequent vascular events. Importantly, recurrent strokes are associated with a higher social and economic impact, higher case fatality, and worse clinical outcome than first-ever strokes. The burden of post-stroke complications, residual deficits, and inadequate medical and psychosocial care all contribute to long-term disability and reduced quality of life in these patients. The Department of Neurology of the Medical University Innsbruck undertook the STROKE-CARD trial (NCT02156778) between 2014 and 2018 with follow-up until 2019 to evaluate the efficacy of the Post-Stroke disease-management program STROKE-CARD care. After implementation of STROKE-CARD care, the investigators aim to document the quality of post-stroke care and compare outcome parameters to historical cohorts and the change over time. Furthermore the investigators aim to gain a large data-resource for future research of biomarkers, disease mechanisms, prognosis and imaging mechanisms for R&D.

This registry is performed for the long-term assessment of outcome, performance and residual safety aspects of the BIOMONITOR III and possible successors in a real-life clinical set-up. In addition, this registry is set up in a way that it may also be used as a platform for submodules to investigate additional scientific and regulatory aspects while minimizing the additional effort for the investigational sites and patients.

This is a multicenter, open-label, evaluator-blinded, investigator-initiated, randomized clinical trial, to evaluate the clinical efficacy and safety of LF-rTMS in reducing infarct size, reducing disability rate and improving functional outcome in patients with acute ischemic stroke within 48 hours after stroke onset.

The purpose of this study is to determine a standardized protocol for swallowing therapy and this protocol's effects on recovery after a stroke

The goal of this clinical trial is to assess the initial safety and performance of the RapidPulseTM Aspiration System in patients experiencing acute ischemic stroke within 24 hours since the onset of stroke symptoms, or last known normal. Subject will undergo mechanical thrombectomy (a procedure to remove a clot in the brain which is preventing blood flow), with the RapidPulseTM Aspiration System. Participating in the trial is for 5-7 days or hospital discharge (whichever is earlier).

PRESSURE is a multicenter, prospective, randomized, open, blinded end-point assessed (PROBE) trial, that aims to evaluate the efficacy and safety of drug-induced hypertension using peripheral dilute norepinephrine, in patients with acute ischemic stroke in a perforating artery territory and experiencing early neurological deterioration.

Although older studies, most of them retrospective in design, advocated sedation over general anesthesia during endovascular treatment for acute ischemic stroke, a recent meta-analysis and randomized studies have shown that general anesthesia is associated with better functional status at 3 months compared with local anesthesia and sedation. In our center, most procedures are performed under general anesthesia, and once the procedure is complete, the patient is transferred intubated and sedated to the ICU. If the patient is hemodynamically and respiratory stable, the patient will be extubated, and will be discharged to the Neurology hospitalization floor. Several factors have been described that may influence the evolution and functional status at three months of patients who have suffered a stroke and have received endovascular treatment, such as the time between the onset of symptoms and admission to the ward for performing the procedure, the use of general anesthesia compared to sedation and local anesthesia, adequate control of blood pressure, the size of the cerebral infarct, or a worse neurological examination at the time of the procedure. In turn, several factors have been described that may influence the success of extubation in a patient who has suffered an acute ischemic stroke and who has required orotracheal intubation, such as the absence of dysarthria, the size of the infarct, the location of the infarction, the NIHSS (National Institutes of health Stroke Scale) or neurological status prior to orotracheal intubation. The investigators do not know, however, whether the time of mechanical ventilation can influence the evolution and functional status at three months of patients who have suffered a stroke and have received endovascular treatment under general anesthesia
