Filter by:The goal of this clinical trial is to learn about efficacy and safety of dual antiplatelet therapy in ischemic stroke with intracranial artery stenosis. The main question it aims to answer are: whether aspirin combined with clopidogrel for 3 month is better than 1 months for patients with non-cardiogenic cerebral infarction with intracranial artery stenosis. Participants will get dual antiplatelet therapy (aspirin plus clopidogrel) for 1 month or 3 months within 7 days of the first stroke. Researchers will compare experimental group (3 months dual antiplatelet therapy) with comparison group (1 month dual antiplatelet therapy), to see if experimental group would reduce stroke recurrence or mortality, and increase bleeding and other adverse prognosis.
Along with the current clinical trial, the efficacy and safety of a 300 mg loading dose of ticagrelor administered within 24 hours of the first-ever large-vessel ischemic stroke compared to 200 mg cilostazol were assessed through NIHSS, mRS, and possible adverse effects.
Along with the current clinical trial, the efficacy and safety of a 300 mg loading dose of ticagrelor administered within 24 hours of the first-ever moderate to severe ischemic stroke compared to 200 mg cilostazol were assessed through NIHSS, mRS, and possible adverse effects.
(1) The main purpose To explore the predictive value of human microbiome and its metabolome for adverse prognosis in patients with acute ischemic stroke (AIS). (2) Secondary purposes 1. To explore the characteristics of cross-regional disturbance of human microbiome in stroke patients; 2. To investigate the characteristics and rules of bacterial flora changes before and after recurrent apoplexy; 3. Markers closely related to AIS prognosis and cognitive emotional complications were excavated by metagenomic, metabolic, peptide and imaging groups. 4. To explore the relationship between serum markers of ultra early stage and prognosis.
Tocilizumab may exert neuroprotective effects in patients with ischemic stroke undergoing endovascular treatment
Acute Basilar Artery Occlusion (ABAO), a condition with a high risk of mortality or disability (up to 80%). The safety and efficacy of endovascular thrombectomy (EVT) in ABAO remains uncertain due to inconsistent evidence from random controlled trials (RCTs). Recent studies have explored the use of MRI in ABAO, this study aims to assess the efficacy and safety of EVT and standard medical therapy (SMT) in the treatment of ABAO within 24 hours of onset. It also aims to explore the feasibility and prognostic value of MRI-based assessment of ABAO infarction using AI image analysis software.
The purpose of this study is to evaluate the safety and tolerability of ascending doses (Part A) and selected doses (Part B) of BB-031 in acute ischemic stroke patients presenting within 24 hours of stroke onset. Participants will be randomized to receive one dose of either the investigational drug or placebo and will be followed for 90 days. A total of 156 patients are planned in this study.
The purpose of this study is to investigate the safety and efficacy of endovascular treatment with or without preceding intravenous Tenecteplase in patients with late-window (4.5-24 hours of symptom onset) acute ischemic stroke due to middle cerebral artery (MCA) M1 or M2 occlusion.
The project is a multicenter, open-label, randomized medical experiment, which was designed to evaluate the efficacy and safety of single-stage pulmonary vein isolation (PVI) and implantation of left atrial appendage occluder (LAAO) in comparison with either isolated LAAO implantation or chronic therapy with non-vitamin K antagonists anticoagulants (NOAC) in patients with recent-onset ischemic stroke and atrial fibrillation (AF). Based on former randomized controlled trials, percutaneous implantation of LAAO was shown to be non-inferior to vitamin K antagonists (VKA), but according to guidelines the use of LAAO is recommended only in patients with absolute contraindication to chronic anticoagulation therapy. PVI constitutes an acknowledged rhythm control management strategy in patients with paroxysmal and persistent AF, which leads to symptomatic relief in about 60% of treated patients, however, its beneficial effect on long-term outcome was demonstrated only in patients with heart failure with reduced ejection fraction. The feasibility and compatibility of both interventions performed as a combined single-stage procedure are warranted by common vascular access via transseptal puncture, which may lead to reduction of procedural cost and shortened overall duration of both interventions. Taking into consideration the preliminary registry data, the combined single-stage PVI and LAAO implantation are thought to be a safe procedure in patients with a high risk of recurrent ischemic stroke and cardiovascular death. The study will comprise 240 patients who were diagnosed with ischemic stroke within preceding 6-12 weeks, with confirmed paroxysmal or persistent AF and low-to-moderate psychomotor dysfunction in the course of cerebral incident, who completed early neurological rehabilitation and are characterized by high risk of ischemic stroke recurrence (CHA2DS2-VASc score ≥2 pts in men; ≥3 pts in women) and who received adequate oral anticoagulation therapy (NOAC/VKA) for ≥4 weeks. After exclusion of thrombus and potential anatomical contraindications to the procedure on transesophageal echocardiography, patients will be randomized in 1:1:1 ratio to study group treated with combined single-stage PVI + LAAO implantation during 3-day hospitalization and to control group subject to LAAO implantation or control group subject to chronic therapy with NOAC. The duration of active enrollment phase will be 18 months. Subsequent follow-up phase will include scheduled outpatient visits (at 3, 12, 48 months) and phone call interview (at 6, 18, 24, 36 months) in order to evaluate the occurrence of clinical and safety endpoints, medical symptoms and signs, quality of life reflected by structured questionnaire, the presence of AF on 7-day Holter electrocardiography. Follow-up visits will also include blood laboratory tests analysis, including biomarkers of heart failure and left atrial wall stress, as well as transthoracic echocardiography with tissue Doppler imaging and strain imaging. In addition, patients in study group and control group treated with LAAO will attend additional outpatient visit at 6 weeks in order to perform transesophageal echocardiography so as to confirm procedural success and allow for termination of chronic anticoagulation therapy. Co-primary composite endpoint will comprise cardiovascular death, ischemic stroke, transient ischemic attack, systemic arterial embolism and major non-procedural bleeding, including intracranial bleeding (non-inferiority). The current project was based on the preliminary results of nonrandomized studies, which delivered evidence for feasibility of combined single-stage PVI and percutaneous left atrial appendage closure and laid ground for future randomized controlled trials. It is expected that the proposed intervention will be non-inferior in terms of composite cerebrovascular events and superior in terms of major nonprocedural bleeding in comparison to chronic NOAC therapy.
The purpose of this study is to evaluate the safety and efficacy of Human Urinary Kallidinogenase combined with endovascular therapy in acute ischemic stroke (AIS) patients with large vessel occlusion.
