Active clinical trials for "Ischemic Stroke"

Stroke-associated pneumonia (SAP) constitutes a clinically relevant complication of stroke, because it increases the mortality and has a negative impact on the neurological prognosis of the patient. An early identification of patients at risk for SAP allowing an early initiation of antiinfective therapy may improve the prognosis. To date, no reliable prediction models or clinical scores for stroke-associated pneumonia exist. Recently, it was shown that parameters indicating an impaired immune function are associated with the subsequent occurrence of SAP and could therefore be used as predictors for SAP. This study will develop and prospectively validate a prognostic score to predict SAP based on clinical parameters. Furthermore, the study examines the prognostic properties of selected immune and infectious parameters for the prediction and diagnosis of SAP. The study will further address the question whether these infectious and immune parameters predict the 3-month-outcome. In a subgroup of patients, MRI parameters on stroke size and localization will be assessed to investigate whether these parameters might allow prediction of SAP or the 3-month-outcome.

The study aims to observe the short term effect (3-month) of sleep disordered breathing (SDB) on cardiovascular parameters, heart rate variability, endothelial function and surrogate markers of atherosclerosis after acute cerebrovascular events (ACE). The long-term effect (6-24-month) of Continuous Positive Airway Pressure (CPAP) on clinical vascular outcome, cardiovascular parameters, evolution of surrogate of atherosclerosis heart rate variability and endothelial function after ACE is observed over 24 months. A preventive effect of CPAP therapy on cerebro-vascular events in patients with moderate-severe obstructive SDB without sleepiness after ictus or transient ischaemic attack will be evaluated.

The purpose of the study is to evaluate the efficacy and safety of Butylphthalide Soft Capsules (En Bi Pu, NBP) in Secondary Prevention of Ischemic Stroke

The main purpose of the study is to get information about the safety and efficacy of treatment with Dapsone to prevent the disability after ischemic Stroke, in patients diagnosed with anterior territory brain infarct.

Pneumonia is a frequent complication of acute stroke and is associated with increased mortality and long-term impairment in the affected subjects. In previous studies, a number of clinical (e.g., dysphagia, severe neurological impairment, mechanical ventilation), radiological (e.g., large infarctions in the territory of middle cerebral artery, insular infarction) and biochemical (e.g., increased serum levels of C-reactive protein, decreased levels of CD4+ T-lymphocytes) findings have been reported as risk factors of stroke-related chest infection. The present study (PRECAST) aims to identify a small set out of these previously described risk factors that can predict stroke-related pneumonia with high sensitivity and specificity.

Treatment of acute stroke is still difficult and the only specific drug approved (rtPA) can only be administered if treatment starts within 3 hours after onset of symptoms. This results in a still too small number of patients treated with rtPA ( < 15% in best clinical care institutions ). Ancrod is a differently acting biological drug which has been used for a long time but not for acute stroke treatment. STAT was the first RCT of medium size to show a significant benefit/risk ration if treatment starts within 3 hours. ESTAT was designed closely related to STAT but with a longer 6 hours window and specifically extended inclusion/exclusion criteria to avoid secondary complications possibly related to a longer time window.

Aim of this study will be the evaluation (by ELISA quantification and quantitative RT-PCR) of circulating biomarkers of damage and regeneration in patients affected by ischemic stroke. The biomarker levels will be measured from the acute event (48h) and in subsequent 4 times (7 days, 30 days, 90 days, 180 days) following hospitalization, up to 6 months after the acute event. These data will then be correlated for all five times with the clinical scales normally used for patient evaluation and will also be associated with MRI-DTI measurements performed in the post-acute (30 days) and post-discharge (180 days) phase.

This is ROM trail study. Data collected from Rabbani Hospital Lahore . in this study total two groups included control and experimental and sample size was 48 and 24 persons divided in each groups as well. Informed consent was taken from the recruited subjects. Two scales BBS and TIS used to measure the outcomes. Data analyse by ssps V21.0 with a significant level of p valued 0.05. Results were in the favour of experimental group.

Urinary kallidinogenase may assist recovery acute ischemic stroke. This study evaluated the impact of urinary kallidinogenase on NIHSS score, modified Rankin scale (mRS) score and fasting glucose levels in patients with AIS combined with diabetes mellitus and impaired fasting glucose.

Atrial fibrillation is a common cardiac arrhythmia and a major risk for ischemic stroke. Furthermore the risk of stroke is higher in the first month after transient ischemic attack (TIA)/stroke. Rivaroxaban has been approved by Health Canada over period of last two years for prevention of stroke and have been found equally effective as oral Vitamin K antagonist. The foremost benefits of NOAC are reduced intracranial bleeding risk and does not require coagulation monitoring. Optimal timing of anticoagulation after TIA/stroke in patients with known non-valvular atrial fibrillation is not known. The practice is variable and opinion based. The bias for many stroke physicians and neurologists is to start later (after 1-2weeks) to prevent hemorrhagic transformation thus possibly exposing the patients to an increased risk of recurrence. The product monograph for the drug suggest to wait for variable of 3 to 14 days before starting the NOAC (Waiting period:14 days for dabigatran and rivaroxaban, 7 days for Apixaban after ischemic stroke and three days after TIA for rivaroxaban). The times have been chosen arbitrary. The investigators aim to study incidence of symptomatic hemorrhage in patients with non-valvular atrial fibrillation who are initiated with new oral anticoagulants early after TIA and stroke.
