Filter by:The primary purpose of this study is to investigate the effectiveness and safety of the Suhexiang Pill for patients with acute ischemic stroke in real-world settings.
The goal of this observational study is to compare severity and mortality rates of acute cerebral infarction(requiring thrombolysis or endovascular recanalization) depending on the type of oral antidiabetic drug taken before the onset of cerebral infarction. Researchers will compare the group that used DPP-4 inhibitors as anti-diabetic drugs before cerebral infarction and the group that did not use them to see the effect of DPP-4 inhibitors in reducing severity of cerebral infarction.
The purpose of this study is to determine the efficacy and safety of levofloxacin in treating acute ischemic stroke.
The goal of this observational study is to compare the differences in the features of cerebral multifrequency EIT(cMFEIT) images between healthy subjects and patients with brain diseases and to explore the possibility of applying multifrequency EIT to intracranial abnormality detection.16 healthy volunteers and 8 patients with brain diseases were recruited as experimental subjects, and the cerebral EIT data of 9 frequencies in the range of 21 kHz - 100 kHz of all subjects were acquired with an EH-300 MFEIT system.
Ischemic post-conditioning is a neuroprotective strategy that has been proven to attenuate reperfusion injury in animal models of stroke. The investigators have conducted a 3 + 3 dose-escalation trial to demonstrate the safety and tolerability of ischemic post-conditioning incrementally for a longer duration of up to 5 min × 4 cycles in stroke patients undergoing mechanical thrombectomy. The purpose of this study is to further determine the efficacy and safety of ischemic post-conditioning in patients with acute ischemic stroke who are treated with mechanical thrombectomy.
This study is designed to observe the treatment options in real-world clinical practice as well as the safety and efficacy of different treatment strategies.
The primary objective of the study is to evaluate the effects of BIIB131 on arterial revascularization (Part 1) and to determine if BIIB131 improves functional outcome as measured by the Modified Rankin Scale (mRS) when compared with placebo following acute ischemic stroke (AIS) (Part 2). The secondary objectives are to evaluate the effects of BIIB131 on angiographic reperfusion and infarct evolution, to determine if BIIB131 improves functional outcome, pharmacokinetic profile of BIIB131 (Part 1); to evaluate the effects of BIIB131 on acute and 90-day clinical outcomes (Part 2).
A fifth of ischemic stroke or transient ischemic attack (TIA) patients will have recurrent events within the first 3 months [Refs 1-3] despite aggressive medical therapy with antiplatelets and risk factor control. Clopidogrel is one of the mainstays of antiplatelet secondary prevention therapy in patients with ischemic stroke. CYP2C19 loss of function (LOF) mutations impair the effectiveness of clopidogrel [Ref 4]. The prevalence of LOF mutations is approximately 60% in the local population [Ref 5], rendering the effectiveness of empiric clopidogrel treatment doubtful. For patients who have LOF mutations, other treatment options for secondary prevention of ischemic stroke need to be tested. This study aims to determine the feasibility and clinical impact of genetic testing guided antiplatelet therapy in ischemic stroke patients on the prevention of major adverse cardiovascular or cerebrovascular events. Clopidogrel naive ischemic stroke or TIA patients aged 21 years and above will be randomised to genetic testing guided antiplatelet therapy or standard medical therapy within 7 days of their index event. Patients allocated to testing group will have blood sample drawn for diagnosis of CYP2C19 LOF mutations. Patients who test positive for an LOF mutation (intermediate and poor metabolisers) will be offered alternative antiplatelet therapy in the form of aspirn (for those who need monotherapy) or aspirin plus ticagrelor or dipyridamole (for those who need dual antiplatelet therapy) to be decided by the managing physician. Patients who test negative for LOF mutation will continue on clopidogrel. Platelet reactivity index (enables the identification of patients with an inadequate response to antiplatelet agents) will be measured at baseline.
A combination therapy proposed to be evaluated in this trial, consisting of three already registered compounds with a validated disease mechanism and with known safety profiles, targets key proteins in the dysregulated signal network in stroke, and is expected to synergistically result in post-stroke blood-brain barrier stabilization and neuroprotection. The synergistic mode of action will allow for low doses and is expected to reduce possible side effects while maintaining maximal efficacy
The goal of this observational study is to evaluate the role of blood pressure (BPV) variability in patients suffering from acute ischemic stroke. The main questions it aims to answer are: 1. To determine the association of BPV with functional/cognitive outcome after ischemic stroke. 2. To determine a pathophysiologic mechanism of BPV's deleterious effect on functional outcome. 3. To evaluate potential treatment targets to pharmacologically reduce BPV after ischemic stroke.
