Filter by:Preprocedural predictors of outcome in patients with acute basilar artery occlusion (ABAO) who underwent endovascular treatment (EVT) remain controversial. The Investigators aimed to analyse, in patients with ABAO treated by EVT, if pre-EVT DWI total posterior-circulation infarct volume (TPIV) was a predictor of 90-days outcomes
Stroke is the first cause of death among Spanish women and main cause of disability. Reperfusion therapies of the occluded artery remain the only useful approach in acute ischemic stroke. However, the efficacy of these strategies is highly time-dependent and due to the need of neuroimaging (CT or MRI) to differentiate between ischemic and hemorrhagic stroke, impossible to be performed at the pre-hospital level. The investigators aim to set-up a point of-care (POC) device to validate a biomarker panel differentiating ischemic and hemorrhagic stroke at the pre-hospital level using a blood sample and to validate a second biomarker panel for the early identification of patients with large vessel occlusions (LVO), which are candidates for mechanical thrombectomy. For that, the investigators will recruit a 300 patients' cohort with pre-hospital blood samples using available POCs for each of those markers.
Preprocedural predictors of outcome in patients with acute basilar artery occlusion (ABAO) who underwent endovascular treatment (EVT) remain controversial. Our aim was to analyze if pre-EVT diffusion-weighted images cerebellar infarct volume (CIV) was a predictor of 90-day outcomes.
The objective of this study is to evaluate the safety and efficacy of a single intravenous administration of JTR-161 (allogeneic stem cell product derived from the dental pulp of healthy adult humans) to patients with acute ischemic stroke. This study is comprised of 3 cohorts and conducted in the order of Cohort 1, Cohort 2 and Cohort 3. Cohort 1 Arm-1: JTR-161, 1 × 10^8 cells/subject, 6 subjects Arm-2: Placebo, 2 subjects The Data and Safety Monitoring Board (DSMB) and the Sponsor will decide whether Cohort 2 can be initiated or not. Cohort 2 Arm-1: JTR-161, 3 × 10^8 cells/subject, 6 subjects Arm-2: Placebo, 2 subjects DSMB and the Sponsor will decide whether Cohort 3 can be initiated or not and the dose of JTR-161 in Cohort 3. Cohort 3 Arm-1: JTR-161, 1 × 10^8 cells/subject or 3 × 10^8 cells/subject, 30 subjects Arm-2: Placebo, 30 subjects
Early outcome prediction after ischemic stroke (IS) is of great importance. Prognosis is usually based on clinical variables and neuroradiological findings while serum biomarkers may contribute to prognostic accuracy. Inflammatory biomarker Suppression of Tumorigenicity 2 (ST2) has been shown as promising in IMU outcome predicting. The relationship between ST2 serum values and IS severity is not fully clarified. The proposed hypothesis is that earlier releasing and higher ST2 serum concentrations will be associated with a worse IS outcome. In this prospective and observational study 20 patients with IS will be included and followed. The primary outcome is functional outcome according to the modified Ranking scale at 90 days. In case of hypothesis confirmation, theoretical contribution will be in a better understanding of pathophysiological changes in acute phase of IS, while the clinical purpose is to improve the prognostic procedure.
Acute ischemic stroke is the most common type of stroke, accounting for about 60%-80% of all stroke, with high incidence, high mortality, high disability rate, has become the first cause of death in China. At present, only ultra-early thrombolytic therapy, endovascular therapy and antiplatelet therapy have obtained evidence-based medical evidence in ischemic stroke treatment, but only thrombolytic therapy and endovascular therapy can improve the good prognosis of patients. Intravenous thrombolytic therapy within 4.5 hours after the onset of ischemic stroke symptoms has been shown to be effective, which is recommended in the guidelines. In most countries, alteplase (R-tPA) is the only drug approved for the treatment of acute ischemic stroke. Recombinant human TNK tissue-type plasminogen activator (rhTNK-tPA) is a modified recombinant tissue-type plasminogen activator, with no procoagulant effect and a longer half life. In recent years, there are some studies on the comparison of therapeutic effects of TNK-tPA and RT-PA in patients with acute ischemic stroke, and TNK shows promising especially for large artery occlussion. At present, there are few reports on the application of rhTNK-tPA in Chinese stroke patients. The aim of this study is to evaluate the efficacy and safety of rhTNK-tPA in Chinese patients with ischemic stroke in a prospective, multicenter registration study.
The goal of this study is to predict and prevent adverse drug events by investigating the impact of genetic variants, demographics, and environmental factors in subjects status post myocardial infarction and percutaneous coronary insertion who have experienced adverse drug events while on P2Y12 inhibitors.
Optimal blood pressure management during endovascular treatment of acute ischemic stroke is not well established. Several retrospective data indicate, that there is a U-shaped relationship of admission blood pressure and functional outcome, where either very high or very low blood pressure are disadvantageous for the patient. Low blood pressure might lead to hypoperfusion in ischemic areas (i.e. penumbra) and to larger infarction sizes, while on the other hand, maladaptive high blood pressure might lead to edema and hemorrhage. Retrospective data investigating intraprocedural blood pressure and its influence on outcome is limited. Some studies indicate that hypotensive blood pressure drops from the level of the admission blood pressure lead to a worse outcome. Intraprocedural hypotensive drops are common during endovascular thrombectomy due to application of necessary sedative drugs for agitated stroke patients. We aim to investigate whether individualized blood pressure management with patient-specific blood pressure targets situated at the level during presentation might be associated with better functional outcome compared with general blood pressure targets for patients during thrombectomy. For this purpose, we plan to perform this single center, parallel-group, open-label randomized controlled trial with blinded endpoint evaluation (PROBE).
Endovascular therapy (EVT) was recommended as the primary treatment for patients with acute large vascular occlusion (LVO) in anterior circulation. However, the evidences of EVT for patients with large infarct volume were limited. In this study, the investigators assume that best medical management plus EVT might be superior than best medical management alone for patients who have evidence of a large infarct volume. The primary objective of the study was to establish the safety and efficacy of EVT in patients presenting with symptoms of acute ischemic stroke (AIS) from LVO in the anterior circulation and having a large infarct volume.
