Filter by:Patients who have suffered a stroke are having an increased risk of having recurrent stroke in the future. This risk of stroke is increased by atrial fibrillation, which often "comes and goes" (called paroxysmal) and hence escapes routine diagnostics. The hypothesis of Find-AF 2 is that enhanced (evaluation in a ECG core lab), prolonged (at least 7 days of rhythm monitoring annually) and intensified (continuous rhythm monitoring in high risk patients) not only finds atrial fibrillation more often, but that changes in therapeutic management (e. g. start of anticoagulation after detection of atrial fibrillation) results in a decrease of cardioembolism (which can be either recurrent stroke or systemic embolism). To prove this hypothesis, patients will be randomised into two groups: the first group will receive the currently available standard care for patients with stroke. In the second group, cardiac rhythm monitoring adapted to the risk of the occurrence of atrial fibrillation is performed - either with a 7-day long-term ECG (at baseline, after 3 and 12 months and every 12 months thereafter) or with continuous monitoring using an implantable cardiac monitor. If atrial fibrillation is detected, this information will be given to the treating study physician. Any therapeutic decision is at the discretion of the treating physician, but should follow current guidelines.
This study is a prospective, open-label, multi-center, registry study, designed to to documents that EmboTrap II usage as a thrombectomy device for emergency large vessel occlusion (ELVO) in terms of the rate of First Pass Recanalization (FPR). Patients with ELVO will initially underwent mechanical thrombectomy usig EmboTrap II. FPR is defined as modified Tissue Thrombolysis In Cerebral Ischemia (mTICI) 2b or 3
The present study is a randomized, multi-center, double-blind, prospective study that tests the efficacy of intravenous milrinone to optimize cerebral hemodynamic and prevent delayed cerebral ischemia (DCI) during the high-risk period (day 4- day 14) in patients with severe subarachnoid hemorrhage due to intracranial aneurysm rupture (SAHa) (WFNS IV-V). The main objective is to evaluate, in comatose patients and / or sedated on D3 following a severe SAHa (WFNS IV -V), the effect of 10 days of milrinone versus placebo, in addition to the usual management, on the volume of DCI lesions measured on CT scan at 1 month.
This is a multicenter, doble blind, placebo controlled clinical trial to asses de safety and efficacy of intravenous administration of alogenic adipose tissue-derived mesenchymal stem cells in the first four days from acute ischemic stroke.
Susceptibility weighted imaging (SWI) technology has developed in the decade which is being a kind of cerebrovascular disease diagnostic tools in the clinical application, especially for paramagnetic material (such as DNA hemoglobin and hemosiderin) has a high sensitivity. The change of the signal on SWI bases on the change of local oxygenated hemoglobin content in the blood and deaeration hemoglobin content ratio, which can be used to indirectly reflect the hypoxia group oxygen intake fraction (OEF) and cerebral metabolic rate. When the intracranial vascular occlusion, corresponding responsibility vascular blood flow area of brain tissue will occur hypoperfusion, brain tissue will improve the compensation in accordance with its own OEF, causing ischemia area inside the venous drainage of deaeration hemoglobin content ratio increases and the hypointensity on SWI ,which display the asymmetric cortical vessel sign (ACVS). Studies have suggested that ACVS is more prone to early neurological deterioration and has a poor long-term outcome. After recanalization of ischemic stroke, the presence of equal CVS(return to normal) on SWI is associated with a good clinical outcome. In addition, the relationship between ACVS grade and collateral circulation in patients with acute ischemic stroke has been studied. For patients with massive cerebral infarction, the relationship between ACVS on SWI and the clinical prognosis of cerebral edema and cerebral hemodynamics is not completely clear. In this study, the clinical data of patients with massive cerebral infarction will be analyzed to explore the relationship between ACVS, cerebral edema , cerebral hemodynamic and clinical prognosis. Sodium aescinate is widely used in cerebral edema caused by cerebral hemorrhage or cerebral infarction.The main mechanism of sodium aescinate is anti - inflammatory, anti - exudate, anti - oxygen free radical, anti - edema, increase vein tension, improve blood circulation and nerve protection. In this study, investigators will investigate whether the application of sodium aescinate had an effect on ACVS on SWI in patients with massive cerebral infarction. Plasma s100-β, procalcitonin, neutrophil count, serum fibronectin, and endothelin-1 could predict cerebral edema in patients with cerebral infarction, this study will analyze the relationship between these markers and ACVS on SWI in patients with massive cerebral infarction.
In 2015, five randomized trials showed efficacy of endovascular thrombectomy over standard medical care in patients with acute ischemic stroke caused by occlusion of arteries of the proximal anterior circulation. However, sufficient recanalization (mTICI2b-3) can 't be acquired in all patients under thrombectomy. There is a lack of evidence that whether salvage intra-arterial thrombolysis is beneficial for patients with insufficient recanalization after endovascular thrombectomy. The EXTEND-IA TNK study indicated that tenecteplase before thrombectomy was associated with a higher incidence of reperfusion and better functional outcome than alteplase among patients with ischemic stroke treated within 4.5 hours after symptom onset. This study intends to explore the proportion of sufficient recanalization (2b/3) after intra-arterial tenecteplase administration in patients undergoing thrombectomy with insufficient recanalization (1/2a).
The main purpose of this trial is to determine whether Chinese medicine (CM) for eliminating phlegm and clearing heat (EPACH) recipe continuously with nourishing Qi and activating blood circulation (NQABC) recipe, oral within 72 hours of symptom onset, improves the 15-day neurologicl deficits in participants with acute ischemic stroke.
This study focuses on the relationship between obesity and stroke, which are both characterized by increasing incidence and prevalence with epidemic proportions worldwide and tremendous socio-economic consequences. Furthermore, obesity is an established risk factor for stroke and affects especially younger people, which increases the stroke incidence in younger patients. Unfortunately, the relationship between overweight and acute ischemic stroke including treatment by thrombolysis has not yet been evaluated thoroughly.
AISRNA is to analyze the expression pattern of circular RNA (circRNA), micro-RNA (miRNA) and long non-coding RNA (lncRNA) by next-generation sequencing in patients with acute ischemic stroke and healthy control. The candidate circRNA/miRNA/lncRNA will be verified as biomarkers for the detection and prognosis of acute ischemic stroke.
This study will test the hypothesis that patients presenting within 8 hours of onset with cerebral ischemia in the setting of proximal large vessel occlusions (LVO) and low baseline NIHSS scores (0-5) will have better 90-day clinical outcomes (mRS distribution) with immediate mechanical thrombectomy (iMT) compared to initial medical management (iMM).
