NCT ID: NCT03247036 Completed - Ischemic Stroke Clinical Trials

Long-Term Survival After Ischaemic Stroke: Ebrictus Study

Start date: January 13, 2017
Phase: N/A
Study type: Observational [Patient Registry]

A number of large trials have confirmed the benefits of thrombolysis in acute stroke, but there are gender differences. We sought to examine the relationship between sex and outcome after thrombolysis. Previous reports [1-6] concerning sex-related differences in stroke management and outcome are inconsistent and sometimes difficult to interpret, and so the reasons for gender disparities in stroke outcome have remained unclear. Functional outcomes and quality of life after stroke are consistently poorer in women despite adjustment for baseline differences in age and prestroke function, and the fact that comorbidities and clinical outcomes were not different between women and men [3, 7] . Once the reasons for these differences are better understood, intervention might be possible to help provide the best care for all patients. This work is a continuation and extension of the Ebrictus Study [8-10] . Prior work has suggested sex-based differences in thrombolytic therapy in subjects with acute stroke [11] .The authors will explore whether sex might modify the effect of thrombolysis on survival and functional outcomes in patients with acute ischemic stroke [12] beyond the usually evaluated time period of 6 months after stroke and compared this with the group without thrombolytic treatment.

Venous and Cerebral Glucose Microdialysis in Neurocritical Care: Validation & Correlation

Start date: December 13, 2017
Phase: N/A
Study type: Observational

This study evaluates the validity of an intravascular continuous glucose monitoring microdialysis probe, and compares the values to routinely inserted cerebral glucose microdialysis to evaluate the hypothesised relationship between intracranial and intravascular glucose levels.

NCT ID: NCT03242304 Completed - Ischemic Stroke Clinical Trials

Neuroactive Steroids in Acute Ischemic Stroke

Start date: April 1, 2016
Phase: N/A
Study type: Observational

Acute ischemic stroke (AIS) represents an economical challenge for health systems all over the globe. Despite increasing knowledge of the pathophysiology of AIS, there is no satisfactory treatment to revert the resulting brain damage. Changes of neuroactive steroids have been found in different neurological diseases. In this regard, the investigators have previously demonstrated that old patients with AIS show changes of plasma cortisol and estradiol concentrations, in that increased steroid levels are associated with a deterioration of neurological status and a worse cognitive decline. The present study assessed in patients with AIS if changes of behavior, brain-derived neurotrophic factor (BDNF) and nitrites (NO-2) (nitric oxide soluble metabolite) bear a relationship with the degree of hypercortisolism. To this purpose, the investigators recruited patients hospitalized at the Central Military Hospital emergency room within the first 24 hours of AIS. Subjects were divided into two groups, each one composed of 40 control subjects and 40 AIS patients, including men and women. The neurological condition was assessed using the NIHSS and the cognitive status with the Montreal Cognitive Assessment (MoCA test). The emotional status was evaluated using the Montgomery-Asberg Depression Rating Scale (MADRS), whereas the Modified Rankin Scale (MRS) was used to determine the functional condition. BDNF and NO-2 plasma levels were measured by ELISA and the Griess reaction method, respectively.

Rt-PA Thrombolytic Therapy in Combination With Remote Ischemic Conditioning for Acute Ischemic Stroke

Start date: July 30, 2017
Phase: N/A
Study type: Interventional

The purpose of this study is to determine the safety and feasibility of remote limb ischemic conditioning(RIC) in acute ischemic stroke patients who received r-tPA thrombolytic therapy.

NCT ID: NCT03231293 Recruiting - Hypertension Clinical Trials

Fimasartan Blood Pressure Lowering After Acute Stroke

Start date: July 28, 2016
Phase: N/A
Study type: Observational

This study evaluates the effectiveness of fimasartan-based antihypertensive treatment and prognosis in post-acute phase of ischemic stroke or transient ischemic attack patients. All participants will receive fimasartan, and the investigators will follow them up for 6 months.

NCT ID: NCT03210623 Not yet recruiting - Ischemic Stroke Clinical Trials

Stent Retriever's(TonbridgeMT) Endovascular Therapy for Acute Ischemic Stroke(AIS)

Start date: July 2017
Phase: N/A
Study type: Interventional

The study is a prospective, multi-center, stratified randomized, single-blind, parallel assignment, active control, non-inferiority trial. Patients are randomized 1 : 1 to either stent retriever(TonbridgeMT) or Solitaireā„¢ for endovascular therapy for AIS. The study aims to evaluate the benefit and safety of stent retriever(TonbridgeMT) for AIS therapy, as compared to Solitaireā„¢.

Phase: Phase 2
Study type: Interventional

This is a Phase II, randomized, double-blinded, placebo-controlled study for subjects with evidence of PSCI.

NCT ID: NCT03201432 Completed - Ischemic Stroke Clinical Trials

Drug Eluting Stents Versus Bare Metal Stents for Treatment of Symptomatic Extracranial Vertebral Artery Stenosis

Start date: May 2014
Phase: Phase 2/Phase 3
Study type: Interventional

Stroke is one of the important causes of disability and death in the world, in which more than half were ischemic strokes. About 1/4 of the ischemic stroke occurred in the vertebral basilar artery system, especially when in the presence of extracranial proximal vertebral artery stenosis. Vertebral artery stenting is a minimally invasive method for the reconstruction of vertebral artery stenosis and the early clinical studies showed that it was feasible, safe and effective, but the high rate of restenosis has become a bottleneck restricting its development. Previous systematic review had suggested that the drug eluting stent might reduce the incidence of restenosis of vertebral artery. However, prospective randomized controlled trials comparing the efficacy of bare metal stents and drug eluting stents on the prevention of restenosis remains absent.

NCT ID: NCT03192332 Not yet recruiting - Ischemic Stroke Clinical Trials

Bridging Thrombolysis Versus Direct Mechanical Thrombectomy in Acute Ischemic Stroke

Start date: August 31, 2017
Phase: N/A
Study type: Interventional

Intravenous thrombolysis with recombinant tissue-type plasminogen activator (IV t-PA) has been the only proven therapy for acute ischemic stroke (AIS) for almost 20 years. Whether IV t-PA prior to endovascular clot retrieval is beneficial for AIS patients with a proximal vessel occlusion in the anterior circulation has currently become a matter of debate and is a relevant unanswered question in clinical practice. The main objective is to determine whether subjects experiencing an AIS due to large intracranial vessel occlusion in the anterior circulation will have non-inferior functional outcome at 90 days when treated with direct mechanical thrombectomy (MT) compared to subjects treated with combined IV t-PA and MT. The secondary objectives are to study causes of mortality, dependency and quality of life in these AIS patients.
