Active clinical trials for "Ischemic Stroke"

Stroke can affect the physical, emotional and social aspects of the patient and their family members. It is the main cause of complex disability, with a high number of people living with its effects. Stroke can result in impairments in motor function, language, cognition, sensory processing, cognition, and emotional disturbances, which can affect the performance of functional activities and mental health status. Getting patients involved in art therapy (AT) class has shown to alleviate stress and promote a sense of wellbeing, which can aid their recovery and rehabilitation. The benefits of art therapy for people living with different health conditions worldwide have been reported, however, its effect on Egyptian patients with stroke has been neglected.

Any platelet function tests have not been widely used in the clinical practice of acute cerebrovascular disease because of the concerns in repeatability, economic performance, and simplicity. Soluble C-type lectin-like receptor 2 (sCLEC-2) is a new marker for platelet activation, which can be easily measured by usual blood collection in routine clinical practice. We planned the sCLEC-2 in Stroke (CLECSTRO), which is a prospective cohort study in patients with acute ischemic stroke (AIS) and transient ischemic attack (TIA). We planned the sCLEC-2 in Stroke (CLECSTRO), which is a prospective cohort study in patients with acute ischemic stroke (AIS) and transient ischemic attack (TIA). The purpose of this study is to evaluate the clinical utility of sCLEC-2 as a biomarker for pathophysiology, differential diagnosis, prediction of prognosis, and monitoring of antiplatelet therapy in patients with AIS and TIA. Subjects are patients with AIS or TIA and control patients required for differentiation from AIS or TIA. The target population is 600 including the patients and the controls. The outcomes include difference in plasma sCLEC-2 level between patients with AIS or TIA and patient controls, correlation between sCLEC-2 after antithrombotic therapy and recurrence or worsening of stroke, difference in sCLEC-2/D-dimer ratio between non-cardioembolic and cardioembolic AIS or TIA, and correlation between baseline sCLEC-2 and outcome (modified Rankin scale score) after 3 months. sCLEC-2 could be a widely useful biomarker to contribute to the progress of precision medicine in clinical practice of AIS and TIA.

Acute ischemic stroke is one of the main diseases leading to high risk of disability and morbidity worldwide. Since intravenous thrombolysis(IVT) can effectively improve the long-term functional prognosis of acute ischemic stroke(AIS), IVT within 4.5 hours of onset has been widely recommended by international guidelines. Although 35-53% of AIS patients achieve functional independence after receiving IVT, there are still a large number of patients who are disabled or even dead, and nearly 70% of patients have ineffective recanalization. Therefore, there is an urgent need for therapeutic drugs after IVT to further improve the prognosis and reduce the burden of AIS. Shuxuetong injection is widely used in China in patients with AIS after IVT, but the situation in real clinical practice is unclear. Therefore, the study aims to evaluate the effectiveness and safety of Shuxuetong Injection in patients with AIS treated with intravenous alteplase and tenecteplase, and obtain high-quality clinical evidence.

The objective of this study was to evaluate the safety and efficacy of early submaximal balloon angioplasty combined with medical therapy vs medical therapy alone for minor stroke/transient ischemic attack with intracranial atherosclerosis etiology.

Recent years have witnessed a change in the therapeutic paradigm of stroke with the advent of mechanical thrombectomy as the reference treatment. However, despite the achievement of effective proximal recanalization in nearly 80% of patients, nearly half of these patients have an unfavorable functional outcome. Several causes can be mentioned, such as the extent of the initial ischemic damage, the occurrence of complications related to reperfusion treatments or the occurrence of thrombosis of the downstream microvascularization. The latter is a phenomenon that has been known and studied increasingly over the last twenty years. It is the result of multiple cellular remodeling following ischemia and at the origin of an endoluminal filling by platelets, inflammatory cells and fibrin. This phenomenon introduces the fundamental difference between recanalization, i.e. the removal of the obstruction by the thrombus, and reperfusion, which translates into a satisfactory supply of oxygen to the ischemic tissues and therefore the expected result of these treatments. However, not all recanalization is necessarily accompanied by reperfusion, which is the phenomenon of no-reflow. This last situation could be explained by downstream microvascular thrombosis. Studies have shown the interest of intravenous thrombolysis associated with mechanical thrombectomy to preserve this vascular bed and improve cerebral reperfusion. More recently, a study has also shown the value of adding intra-arterial thrombolysis after mechanical thrombectomy. Nevertheless, there is currently no clinical evidence of the reality and prognostic importance of downstream microvascular thrombosis. Advances in imaging have allowed the development of susceptibility weighted imaging (SWI) sequences with millimeter resolution, allowing a precise study of vascular damage and the appearance of previously unseen remodeling. Among them, the existence of cortical or juxta-cortical microinfarcts whose remnographic characteristics differed by the presence of a SWI hyposignal. The hypothesis evoked is that of a hemorrhagic remodeling consecutive to the barrier rupture. However, in view of the pathophysiology explained so far and the hypointense character of the thrombi on the SWI sequences, these remodeling could in fact be not microbleeding but rather markers of thrombosis in the downstream microcirculation. MRI would allow to identify the presence and the importance of microvascular thrombosis and thus to bring arguments to specifically target this microvascular component, consequence of cerebral ischemia, by antithrombotic or thrombolytic treatments. The objective of our project is therefore to carry out a study focused on a better description and understanding of cortical and basal ganglia SWI hyposignals with a histopathological correlation and with the clinical prognosis.

The purpose of this study is to assess the efficacy and safety of recombinant human tissue plasminogen kinase derivatives for injection and alteplase in the treatment of patients with acute ischemic stroke within 4.5 hours.

To evaluate the efficacy and safety of sofadil injection in the treatment of acute ischemic stroke

When to start anticoagulation in patients with an acute ischaemic stroke and atrial fibrillation (AF) is a relevant unanswered question in clinical practice. Direct oral anticoagulants (DOACs) are highly effective for secondary stroke prevention in these patients, but DOACs were never initiated <7 days after stroke onset in recent trials. The ELAN trial will determine the net benefit of early versus late initiation of DOACs in patients with acute ischaemic stroke related to AF. The main objective is to estimate the net benefit of early versus late initiation of DOACs in patients with acute ischaemic stroke related to AF. The secondary objectives are to assess all vascular events and all-cause mortality after early initiation of DOACs in patients with acute ischaemic stroke related to AF compared to late initiation.
