Filter by:Up to 50% of acute ischemic stroke patients with large vessel occlusion failed to achieve functional independence even after successful reperfusion therapy, a phenomenon that is referred to as "futile recanalization". The mechanism of futile recanalization is complex, and some studies have shown that it may be related to factors such as tissue no reflow, reocclusion, poor status of collateral circulation, hemorrhagic transformation, impaired cerebrovascular autonomic regulation, and low perfusion volume. Several studies suggested that maximizing the improvement of cerebral reperfusion is still the primary goal of acute large vessel occlusive stroke. Structural and functional alterations in the microvascular system may be a major obstacle to reperfusion. In animal models of cerebral ischemia, downstream microvascular thrombosis may occur in the early stage of cerebral ischemia and before vascular recanalization, which is the main factor leading to incomplete reperfusion and affecting the efficacy of endovascular thrombectomy. Mechanical thrombectomy mainly addressed the occluded large arteries, and does not consider the distal arteries. However, the recanalization of occluded large arteries does not necessarily translate into successful reperfusion of the ischemic tissue supplied by the distal capillaries. Even with complete recanalization, impaired microcirculatory reperfusion may lead to poor clinical outcomes. Therefore, we speculate that at the end of endovascular thrombectomy, microthrombi remain present in the microcirculation of brain tissue in patients with complete or near-complete cerebral angiography, and that microthrombi is more likely to be dissolved than thrombus more proximal to the heart. Therefore, intra-arterial administration of pharmaceutical, such as tirofiban, may be the only possible option to ensure complete reperfusion of ischemic tissue. Tirofiban is a platelet glycoprotein IIb/IIIa receptor antagonist, which has been widely used in acute coronary syndrome, and its role in acute ischemic stroke has attracted more and more attention from stroke experts. Previous studies have suggested that tirofiban can further increase the incidence of successful recanalization, while reducing the reocclusion rate. Whether early administration of intraarterial and intravenous tirofiban can further improve the clinical outcomes of patients with large vessel occlusive stroke after successful mechanical thrombectomy remains unclear.
The Investigators will create a clinical database and a Biobank of stem cells derived from the blood of participants with cardiovascular disease. The Investigators will recruit participants from diverse racial and ethnic backgrounds with equal representation from both sexes. The Investigators expect to create stem cells and analyze the blood for protein biomarkers and genetic causes of cardiovascular disease. The stem cell biobank and clinical data will be a powerful tool for studying cardiovascular disease.
Cardiac Intensive Care Units (CICUs) provide care for a diverse patient population. Understanding the clinical characteristics, analysis of treatment modalities, and prognosis of patients hospitalized in the CICU are important to improve cardiovascular care. The purpose of this registry is to determine the demographics, clinical, treatment, and prognosis of patients hospitalized in the Polish CICUs. Data from this multicenter, prospective observational study will provide more robust data to facilitate quantitative characterization of cardiac care in contemporary Polish CICUs and enable the development of infrastructure for clinical trials in CICUs.

Community-based exercise programs have demonstrated potential for implementation in older adults; however, it remains imperative to ascertain whether this strategy will yield comparable benefit in stroke patients with dysphagia.Participants were randomly assigned to either the intervention group or the control group. Patients in the intervention group received swallowing function training in community public spaces for 5 days every week for four-week period (60 minutes per day). Patients in the control group received no intervention. Penetration-Aspiration Scale and Standardized Swallowing Assessment (SSA), depressive symptoms (Geriatric Depression Scale-15), and meal duration were assessed before and after all the treatment.
This project will investigate the effects of an 8-week theory-driven online/hybrid Self-employment Skill Building Intervention on the rate of self-employment, self-efficacy, life satisfaction, and psychosocial outcomes among working-age stroke survivors.
The purpose of this research, which has been determined as non-significant risk by the central IRB overseeing the study, is to obtain information to help further develop a machine (a medical device) to measure the pressure around the brain from the outside (this pressure is called intracranial pressure or ICP). Monitoring and managing ICP is an important part of care for patients with conditions such as Traumatic Brain Injury (TBI). However, the current way of measuring ICP requires surgery to drill a hole into the skull, and therefore can introduce additional risks such as infections and pain. Recent research has shown it may be possible to measure ICP without needing surgery. This technology is in development, but large amounts of data is required to build these new devices. Through collecting a large database of information from patients who have both the routine surgical device and the research device applied to their head, the research team will work to develop and test an effective and potentially safer way of monitoring patient ICP.
This trial aims to demonstrate that the Neuralert Monitoring System will detect strokes before they would be identified by current standard of care. Each patient will be monitored for up to five days, depending on device connectivity or battery duration. Each monitoring session will consist of wearing a Neuralert device on each arm. For this pilot trial, we are interested in learning about Wi-Fi connectivity, successful data transmission, clinical usability, and tolerability.
The aim of the planned study project is to assess the current situation regarding the treatment of patients with severe stroke at the neuro-critical care unit. Specifically, determination of whether the target parameters recommended in the guidelines for temperature, systolic blood pressure, mean arterial blood pressure, blood glucose, arterial oxygen partial pressure and arterial carbon dioxide partial pressure had to be maintained. From the planned data analysis, the need for the introduction of cerebrovascular bundles can be derived and planned.
The study investigates the potential of Electromyography (EMG)-triggered Constraint-Induced Movement Cycling Therapy (CIMCT) versus General Cycling Training (GCT) to enhance balance, strength, and daily activities in chronic stroke patients. Over a period of four weeks, this single-blind randomized controlled trial aims to explore how these interventions can assist in stroke rehabilitation. The research has been approved by the Ethics Committee of Kyungdong University and adheres to the ethical standards laid out in the Declaration of Helsinki.
