Shuxuening injection is a multi-target neuroprotective agent, it is expected to play a neuroprotective role on the basis of intravenous thrombolysis therapy. The primary purpose of this multicenter, randomized, double-blind, placebo-parallel controlled trial is to evaluate the efficacy and safety of Shuxuening injection in the treatment with intravenous thrombolysis in patients with ischemic stroke.
Endovascular therapy (EVT) added on best medical management is currently recommended in acute large vascular occlusion (LVO) stroke patients with National Institutes of Health Stroke Scale (NIHSS) score >5. Thus, a sizeable fraction of patients with LVO and a minor stroke that do not receive recanalization therapies may experience an early neurological deterioration (END) due to the expansion of the hypoperfused area, possibly leading to poor long-term functional outcome. However, whether these patients may still benefit from a rescue EVT is unknown, especially in a late window (>24 hours). In this study, the investigators assume that best medical management plus EVT might be superior than best medical management alone in a late window for patients with LVO and a minor stroke who have experienced an END. The primary objective of the study was to establish the safety and efficacy of EVT in a late window for patients with LVO in the anterior circulation and a minor stroke who experienced an END .
The aim of this study is to develop a multicenter registry of patient data and outcomes for patients undergoing intracranial thrombectomy for acute ischemic stroke secondary to emergent large vessel occlusion with delivery of reperfusion catheter over a novel macrowire (Aristotle Colossus) to perform intracranial mechanical thrombectomy.
This single-blinded, randomized controlled was aimed to compare the efficacy of Frenkel's and Conventional Balance Exercises in improving balance and quality of life in patients with subacute ischemic stroke. The participants of Group A received 'Frenkel's Exercises'. In contrast, Group B participants received 'Conventional Balance Exercise' interventions three days/week for 30-60 minutes for four weeks. The data was collected pre and post-treatment on the Berg Balance Scale and Stroke Specific-Quality of Life.
This study will critically examine the feasibility, safety and efficacy of HBOT during inpatient rehabilitation (IPR) after acute ischemic stroke measured by non-disruption of 3 hours of daily therapy, frequency of neurological deterioration or complications (seizure, hemorrhage, brain edema), and functional communication, activities of daily living (ADLs) and mobility.
Rationale: Distal Medium Vessel Occlusion (MeVO) are thought to cause as many as 25% to 40% of all acute ischemic strokes (AIS). Despite their relatively high frequency, there is no consensus regarding the optimal management of these patients. However, the fact that AIS related to MeVO often results in significant disability despite best medical treatment (including intravenous thrombolysis, IVT) calls for novel treatment approaches. Fortunately, a growing number of non-randomized studies have now been published demonstrating the feasibility of endovascular treatment (EVT) for MeVO strokes. These studies have demonstrated that distal EVT leads to high rates of successful reperfusion and may be performed with a comparable safety profile to that of EVT for proximal arterial occlusions. Therefore, a strong rational exists to test the safety and efficacy of EVT for MeVO stokes in a prospective randomized clinical trial. Objectives: The primary objective of this study is to evaluate the hypothesis that endovascular thrombectomy is superior to standard medical management in achieving more favorable outcomes according to the modified Rankin Scale scores at 90 days in subjects presenting with acute ischemic stroke related to a distal medium vessel occlusion within 12 hours from symptom onset (defined as time last know well, TLKW). Secondary objectives include the assessment of the cost-effectiveness of endovascular thrombectomy in the medium vessel occlusion (MeVO) population as well as its impact on health-related quality of life. Study design: The study is a prospective, multicenter, investigational, randomized, controlled, open-label study with blinded endpoint evaluation (PROBE design) and an adaptive design with population enrichment. Study population: Subjects presenting with acute ischemic stroke within 12 hours from TLKW and whose strokes are attributable to a distal medium vascular occlusion defined as M2 segment or M3 segment of the MCA, the ACA (A1, A2, or A3 segments), or the PCA (P1, P2 or P3 segments) with evidence of salvageable brain tissue on perfusion imaging, M2 segment vessel diameter should not exceed 2.5 mm. Primary outcome: Shift in distribution of all levels of the 90-day the modified Rankin Scale with levels 5-6 combined (mRS; 0, 1, 2, 3, 4, 5-6) as assessed by structured assessment.
Non-vitamin K antagonist oral anticoagulants (NOACs) are recommended over warfarin in preventing stroke and thromboembolism among patients with atrial fibrillation (AF) in several guidelines. To evaluate the pharmacological effects of NOACs, directly measuring the concentration is the most arbitrary way since the correlation between concentration and common coagulation tests are not reliable. Our previous investigation reported under the fixed dose regimen, dabigatran exposure increased in elderly, renal impairments and patients with multiple co-morbid conditions. Our data also showed difference in NOACs exposure in Asians. For example, patients under rivaroxaban, in comparison to apxiaban, were more likely to have lower than expected range drug level. Furthermore, the NOACs concentration also affected by the prescription pattern of physicians (non-compliant to labeled dose) and patients' behavior (poor medication adherence). The relationship between NOACs exposure and safety has been elucidated in large-scale clinical trials. As the NOACs level increased, the risk for bleeding increased, too. Nevertheless, no additional protection was noted with increased NOACs levels. In post marketing surveillance, bleeding and thrombotic events have been reported. Investigating the NOACs level among these patients helps evaluating the residual drug in the body, which could be a reference for clinical decision in emergent situation. Specific purpose: Investigate the correlation between NOACs concentration upon the arrival of emergency department (ED) and important clinical outcomes including systemic thromboembolism, and major bleeding. Direction for investigation: 1. Prospectively record the NOACs concentration among AF patients under NOACs therapy and suffered from ischemic stroke (IS), transient ischemic attack (TIA), intracerebral hemorrhage (ICH) and other major bleeding. 2. Investigate the correlation between NOACs concentration upon ED arrival and thromboembolic or bleeding events. 3. Propose a therapeutic range for NOACs, in order to provide a guide for important decision in acute setting.
Patients presenting with mild symptoms of acute ischemic stroke are common and account for approximately half of all acute ischemic stroke. About 30% of patients with minor stroke have a 90-day functional disability. Radiologically proven a large vessel occlusion (LVO) in patients with minor stroke is a well-established predictor of poor outcomes, while the poor outcomes following best medical management in patients with minor stroke with the underlying presence of a LVO are mainly driven by the occurrence of early neurological deterioration (END). Considering the well-known strong association between lack of arterial recanalization and END, endovascular therapy (EVT) appears as an attractive option to improve functional outcomes for LVO-related patients with stroke with mild symptoms. Whether EVT is safe and effective in patients with mild stroke with an LVO is currently debated, since these patients were typically excluded from the pivotal EVT trials. The current study aimed to further test the hypothesis that endovascular therapy would be superior to medical management with respect to functional recovery among low NIHSS patients caused by acute large-vessel occlusion in the anterior circulation.
The purpose of this study is to determine the effect of ginkgo biloba extract on cognitive function in acute ischemic stroke.
This study aims to conduct a multicenter, prospective, randomized clinical trial to scientifically evaluate the safety and efficacy of different perioperative sedation methods during endovascular thrombectomy in acute ischemic stroke patients with large vessel occlusion in the anterior circulation.
