Active clinical trials for "Stroke"

The main aim of this study is to identify the predictive value of CT parameters (e-ASPECTS, CTP, collateral vessel status, volume, and location of ischemic lesion volume) at a 3-month functional outcome defined by the modified Rankin scale (mRS) in patients with non-lacunar stroke after recanalization treatment (Intravenous Thrombolytic Therapy and/or Mechanical Thrombectomy, or conservative treatment).

Introduction Remote cerebral hemorrhage following reperfusion treatment in ischemic stroke is rare (1.3-3.7% of all treated strokes) and is associated with worse functional and vital prognosis. Multicenter observational studies suggest that amyloid angiopathy may be one of the main risk factors for remote hemorrhage. Currently, it is unknown what happens to those patients with remote hemorrhage beyond 3 months of follow-up in terms of risk/benefit balance when receiving antiplatelet or anticoagulant therapy, as well as from a cognitive point of view. Considering an analogy with amyloid angiopathy, the hypothesis is that those patients with remote hemorrhage have a higher risk of intracranial hemorrhage during follow-up when receiving stroke secondary prevention, and will also present greater cognitive deterioration during long-term follow-up. Main Objectives To explore the frequency and risk factors for intracranial hemorrhage during follow-up of patients with remote cerebral hemorrhage. To explore the frequency and progression of cognitive deterioration during follow-up in patients with remote cerebral hemorrhage. Methodology Observational, prospective, multicenter registry with a population-based case-control design of consecutive patients with remote hemorrhage following reperfusion therapy in acute ischemic stroke. Inclusion criteria: Diagnosis of ischemic stroke with age greater than or equal to 18 years who has remote cerebral hemorrhage after receiving reperfusion therapy in the acute phase. Exclusion criteria: Lack of basic data (age, sex, neuroimaging data) or telephone for follow-up. The cases will be those patients with remote hemorrhage. For each case included, 4 consecutive controls will be included (2 with local parenchymal hemorrhagic transformation and 2 without hemorrhagic transformation). The data will be filled out within the (Codi Ictus de CATalunya) CICAT registry form (currently mandatory in all stroke centers in Catalonia) to which additional variables will be added. Telephone follow-up will be conducted at 3, 12, and 24 months. Main study variable: Any type of spontaneous or traumatic intracranial hemorrhage during a 24-month follow-up. Score on the "Short Informant Questionnaire" scale (a validated 17-question questionnaire to be conducted over the phone, where a score higher than 57 points indicates cognitive impairment). Expected sample size during a 2-year recruitment period: 105-300 patients (considering the participating centers to date). Additional information. This study is endorsed by the "Pla Director de la Malaltia Vascular Cerebral" in Catalonia. Participating Centers. Participation offers have been sent to the 28 hospitals in the hospital network of Catalonia with the capacity to administer intravenous fibrinolysis. Positive responses have been received from 13 of them so far. In case the project is accepted by the (Comité Ético de Investigación Clínica) CEIC Sant Pau, the centers that have not responded will be contacted again to obtain their participation.

This is an observational, prospective, multicenter, cohort study in patients with cardioembolic stroke and previous oral or parenteral anticoagulant therapy. Patients in which anticoagulante therapy is mantained will be compared to those in which it is interrupted, in terms of stroke or systemic embolism and haemorrhagic transformation.

The study aims to examine whether trunk control affects sitting balance and upper extremity functions in patients with subacute stroke.

The aim of the study is to know the validity and reliability as well as to translate and culturally adapt the Nottingham Extended Activities Of Daily Living Scale into Urdu language in Pakistani population of Stroke. This study also aims to correlate the scale with the Modified Barthel Index and Frenchay Activities Index.

Study the prevalence of strokes in the emergency department (ED) and their possible eligibility for thrombolysis.

Perioperative stroke is a devastating complication of cardiac surgery that is currently poorly characterized but occurs in 1-5% of patients and is associated with poor outcomes including increased mortality. Given the uncommon nature of this complication, relatively little is known about which factors predict these outcomes among those who experience a perioperative stroke. The study objectives are to identify predictors of mortality, length of stay and discharge disposition after perioperative stroke in cardiac surgery using the prospectively-collected American College of Surgeons National Surgical Quality Improvement Program database between 2005 and 2020.

Some patients develop cognitive decline after a stroke, but we don't always understand the mechanisms. It has been proposed that a proportion of the patients develop an autoimmune immune response, and that this could potentially explain the cognitive decline in some of the patients. The current study aims to investigate this hypothesis in a subgroup of patients with stroke.

This is a multi-center, prospective,continuous registry study. The investigators will include 3000 young adult (18-45 years old) patients with confirmed first-ever acute ischemic stroke in China. The main purpose of this study is to build the study cohort of young ischemic stroke patients in China, and to compare the prognosis and stroke recurrence of young patients with different ischemic stroke subtypes. Secondary objectives are trying to find biomarkers of stroke recurrence.

This study evaluates changes in swallowing using endoscopic swallowing studies and measuring of pharyngeal sensitivity, taste and smell in stroke patients. Younger (<60 years) and older (>60 years) volunteers will serve as control.
