This study aims to construct a registry platform for microcirculatory disorders in a large sample of Chinese patients with cerebral small vessel disease and ischemic stroke; To explore the role of microcirculatory disorders in different types of cerebral small vessel disease and iachemic stroke, as well as their pathogenesis, severity, and prognosis; And to research on the drug treatment of microcirculatory disorders for cerebral small vessel disease and stroke in the real world.
The overall goal of this project is to determine if machine learning and analysis of neurospecific biomarkers can enable early detection of upcoming or ongoing cerebral ischaemia in patients suffering from subarachnoid haemorrhage with altered consciousness due to cerebral injury or sedation. Analyses of heart rate variability, electroencephalgraphy,nearinfrared spectroscopy, cerebral autoregulation, and brain injury specific biomarkers in blood and cerebrospinal fluid will be performed.
The purpose of this study is to evaluate the efficacy and safety of early tirofiban administration in patients undergoing IVT
A Phase II, Randomized, Double-blind, Parallel, Placebo-controlled Study to Assess the Safety and Efficacy of Human Umbilical Cord Blood Infusion in Patients with Acute Ischemic Stroke
This is a single center, randomized, double-blind, placebo-controlled, dose-Escalation clinical study to investigate the safety and efficacy of EPCs transplantation in Acute ischemic stroke.
Atrial fibrillation (AF) is one of the most common cardiac arrhythmias and cardioembolic stroke due to AF is its major complication. Direct oral anticoagulants (DOAC) reduce the risk of cardioembolism in patients with AF. Despite DOAC therapy, there is a significant residual stroke risk of 1-2%/year. Recent data from the Swiss Stroke Registry found 38% of patients with AF and ischemic stroke were on prior anticoagulant therapy (approximately 400 patients per year in Switzerland). The investigators found in a prior observational study, that patients with AF who have ischemic stroke despite anticoagulation are at increased risk of having another ischemic stroke (HR 1.6; 95% confidence interval, CI 1.1-2.1). Combining observational data from 11 international stroke centres, the investigators found that the majority of ischemic strokes despite anticoagulation in patients with AF is "breakthrough" cardioembolism (76% of patients) and only a minority of 24% is related to other causes unrelated to AF. Optimal secondary prevention strategy is unknown. The investigators have conducted two independent observational studies including together >4000 patients but did not identify any strategy (e.g. switch to different DOAC, additional antiplatelet therapy) that seems superior. A recent randomized controlled trial on surgical occlusion of the left atrial appendage (LAAO) found that LAAO may provide additional protection from ischaemic stroke in addition to oral anticoagulation. Triggered by this finding, the investigators performed a matched retrospective observational study and found that patients with AF and stroke despite anticoagulation who received a combined mechanical-pharmacological therapy (DOAC therapy + LAAO) had lower rates of adverse outcomes compared to those with DOAC therapy alone. Therefore, the investigators hypothesize that in patients with AF and ischemic stroke despite anticoagulant therapy, LAAO in addition to anticoagulation with a DOAC is superior to DOAC therapy alone. The investigators propose an international, multi-center randomized controlled two-arm trial to assess the effect of LAAO in patients with AF suffering from strokes despite anticoagulation therapy and without competing stroke etiology. The investigators will use the PROBE design with blinded endpoint assessment. The investigators will enrol patients with non-valvular AF and a recent ischemic stroke despite anticoagulation therapy at stroke onset. Patients will be randomized 1:1 to receive LAAO + DOAC therapy (experimental arm) or DOAC therapy alone (standard treatment arm). The primary endpoint is the first occurrence of a composite outcome of recurrent ischemic stroke, systemic embolism and cardiovascular death during follow-up. Secondary outcomes include individual components of the primary composite outcome, safety outcomes (i.e. symptomatic intracranial haemorrhage, major extracranial bleeding, serious device- or procedure-related complication), functional outcome (modified Rankin Scale) and patient-oriented outcomes. The minimum follow-up is 6 months and all patients will receive follow-ups every 6 months until end of study, the maximal follow-up will be 48 months. Based on prior observational data from the investigators' group and others (5 observational studies, >5000 patients), the investigators estimate the proportion of patients with the primary outcome in the standard treatment arm to be 18% in the first year and 9% in the second year (=cumulative 27% after 2 years). A relative risk reduction of 40% at 2 years would be clinically relevant. Based on these assumptions and a log-rank test, the investigators would need 98 events for a power of 80% at an alpha-level of 5%. Assuming a recruitment rate of 52, 118, 156 and 156 patients in years 1 to 4, an additional 6 months of follow-up (mean follow-up time of 2.1 years) and a uniform drop-out rate of 7.5% per year, 482 patients would need to be enrolled. How to treat patients with an ischemic stroke despite anticoagulation is a major yet unresolved clinical dilemma. This trial has the potential to answer the question whether LAAO plus DOAC therapy is superior to current standard of care for patients with AF who have ischemic stroke despite anticoagulation.
Ischemic stroke has high morbidity and mortality worldwide. Stroke patients experience physical, psychological, and social problems, and require rehabilitation. The aim of stroke rehabilitation is to support patients in optimizing their physical, functional, mental, social, and occupational aspects. Telerehabilitation-based coaching interventions are among the individualized interventions applied to patients. This study aimed to examine the effects of telerehabilitation-based coaching interventions on self-efficacy, modifiable risk factors, and repeated hospitalizations in patients with ischemic stroke. It is predicted that discharge education in disease management and telerehabilitation-based coaching interventions will increase self-efficacy, reduce modifiable risk factors (blood pressure, cholesterol, triglyceride, HbA1c levels, body mass index, smoking, and alcohol use), and reduce repeated hospitalizations. With an education booklet prepared for ischemic stroke patients and primary care providers, one-on-one face-to-face education is planned while patients are in the clinic on the fourth or fifth day of stroke. Determination of individual goals with motivational interview, sending educational videos prepared in cooperation with the multidisciplinary health team to the phones or e-mails of the patients, providing telerehabilitation-based coaching a total of seven times for three months after discharge, monitoring the targets set weekly and monthly, and monthly follow-up after three months. It is planned to support patients with practices such as achieving their goals, maintaining healthy lifestyle changes such as diet and physical activity, and monitoring metabolic parameters. The evaluation form of the education booklet, videos prepared with the cooperation of the multidisciplinary team, and phone call evaluation form will be evaluated by 10 experts. The preliminary application will be tested with 6 patients, and the final form will be provided. The second phase of the study was designed as a single-center, single-blind (participant), randomized controlled study. The study will be carried out with a total of 60 patients with ischemic stroke, 30 in the intervention group and 30 in the control group, who continued to be followed up and treated at the Neurology Clinic of Akdeniz University Hospital.
The goal of this clinical trial is to assess the initial safety and performance of the RapidPulseTM Aspiration System in patients experiencing acute ischemic stroke within 24 hours since the onset of stroke symptoms, or last known normal. Subject will undergo mechanical thrombectomy (a procedure to remove a clot in the brain which is preventing blood flow), with the RapidPulseTM Aspiration System. Participating in the trial is for 5-7 days or hospital discharge (whichever is earlier).
