Active clinical trials for "Ischemia"

The aim of this study is to know the characteristic of "one-per-mil" tumescent solution in regards of the optimal time delay to achieve optimal visualization of operation field in hand and digit surgery. Hypothesis: Epinephine in "one-per-mil" concentration by tumescent injection technique will provide faster decrease in oxygen saturation compared to normal saline solution injected by tumescent technique. Epinephrine in "one-per-mil" concentration by tumescent injection technique will provide effectiveness in vasoconstriction longer than 10 minutes as the optimal time delay. Epinephine in "one-per-mil" concentration by tumescent injection technique causes no finger necrosis as normal saline solution injected by tumescent technique.

The goal of this study is to show the efficacy and safety of heparin and nadroparin in the acute phase of ischemic stroke. Therapeutic agents are administered at intervals of 4.5 to 2 hours after onset of clinical signs. Overall administration of anticoagulant agents will test 72 hours. Randomized patients will be divided into three groups. The first group of patients will receive heparin intravenously at the beginning of 2500 UI bolus intravenously, followed by intravenous pump 1000 UI / h (18-20 IU / kg / hr) to reach 2-2.5 times the baseline aPTT. After 24 hours, patients will receive the group Nadroparin subcutaneously in the therapeutic dose. Second group of patients will be administered subcutaneously Nadroparin the therapeutic dose as recommended. The third group of patients are those who will receive placebo intravenously and 24 hours after receiving nadroparin subcutaneously in the therapeutic dose. All patients will receive after 24 hours of starting treatment 100 mg of aspirin per orally. For initiation of treatment will be assessed: Modified Rankin Scale, National Institutes of Health Stroke Scale, inclusion, exclusion criteria Sign the informed consent and patient randomization Laboratory parameters: glucose, creatinine, GGT, K, Na, Cl, blood count, basic coagulation Women of childbearing age (pregnancy test) History, clinical presentation, medical history, basic internal review of the status (blood pressure, pulse, body temperature, etc.). Initial CT examination of the brain EKG USG sections of extracranial carotid and vertebral arteries special hematology factors If a patient meets all the necessary criteria, he may be given the test substance. During the first 24 hours will be monitored at regular intervals vital functions. After 24 hours, each patient received subcutaneous Nadroparin the therapeutic dose and also 100 mg of aspirin per orally. In the interval from 24 to 30 hours of starting treatment the patient will be made: Control CT brain EKG Basic coagulation Reduction to stop treatment for newly identified haemorrhage or severe and extensive focal cerebral ischemia by CT scan special hematology factors 72 hours, 7, 30 and 90 days after starting treatment, the patient's clinical evaluation using the Modified Rankin Scale, National Institutes of Health Stroke Scale and Barthel Index. Safety endpoints: mortality, adverse side effects, bleeding

HAIS-SE is evaluating for the first time ever in a randomized controlled trial efficacy, tolerability, practicability and safety of endovascular versus surface cooling in awake stroke patients.

This study seeks to evaluate the efficacy and safety of mildronate injection in treating acute ischemic stroke

To compare the efficacy and cost-effectiveness between purified CD34+ cells and peripheral blood mononuclear cells in treatment of critical limb ischemia

The main objective of the SENIOR study is to establish the efficacy and safety of the everolimus eluting stent with a biodegradable abluminal polymer (SYNERGY II) associated with a short dual antiplatelet therapy (DAPT) in patients ≥75 years old, suffering from stable angina, silent ischemia (1 month DAPT) or acute coronary syndromes (6 months DAPT) related to significant coronary artery disease and requiring percutaneous coronary intervention. The primary end point is to demonstrate that SYNERGY II in patients ≥75 years old is associated with a lower rate of the composite rate of major cardiovascular and cerebrovascular events (all-cause death, myocardial infarction, stroke, ischemia-driven target lesion revascularization) and a similar risk of stent thrombosis than bare metal stent at one year.

Dementia is a very frequent cognitive disorder among elderly individuals. Its prevalence is about 15-20% of the population over the age of 65. The most common forms of dementia among the elderly demented patients are Alzheimer's disease (AD) (prevalence of 70%) and Vascular dementia (VD) (prevalence of about 30-40%).There is also a high rate (about 40%) of coexisting of AD and VD among the dementia patients, defined as mixed dementia. Mild Cognitive Impairment (MCI) is a pre-dementia phase of cognitive decline. It is also considered as a prodromal phase of both VD and AD. Its basic clinical features include: cognitive concern, reflecting a change in cognition, reported by the patient or informant (i.e., historical or observed evidence of decline over time), with objective evidence of impairment in one or more cognitive domains (i.e., by formal cognitive testing), as well as preservation of independence in functional abilities and not being demented (i.e., no significant impairment social or occupational functioning). Hyperbaric oxygen therapy (HBOT) has been investigated for treatment of numerous diseases for more than 300 years. The principal effect of HBOT is increasing the solubility of oxygen in plasma to a level sufficient to support tissues with minimal oxygen supply carried on by hemoglobin. Clinical studies published this year present convincing evidence that hyperbaric oxygen therapy (HBOT) can be the coveted neurotherapeutic method for brain repair. Thus, it seems that HBOT might be an efficient and clinically feasible method capable of increasing tissue/cellular oxygenation and effectively evoking neuroplasticity in the chronically vascular-lesioned areas during the post microvascular lesion phase. This is a prospective, randomized, control crossed over, study evaluating the effect of HBOT in patients suffering from Mild Cognitive Impairment and Vascular Subcortical Ischemia.

Transient ischemic attack (TIA) or minor ischemic stroke has a high risk of early recurrent stroke. As the golden standard, aspirin effect modestly on acute ischemic stroke, and slightly increase the risk of intracerebral hemorrhage. Recently, edoxaban, a new oral anticoagulant, is proved to be as effective as traditional anticoagulants, while carrying significantly less risk of intracranial hemorrhage. This trial is a randomized, double-blind, multicenter, controlled clinical trial in China. The investigators will assess the hypothesis that a 30-days edoxaban regimen is superior to aspirin alone for the treatment of high-risk patients with acute nondisabling cerebrovascular event.

This will be a randomized, double-blind, placebo-controlled, multi-center, multi-national, escalating dose, pilot study comparing two doses of THR-18 to placebo when administered to patients suffering acute ischemic stroke and treated with Tissue Plasminogen Activator (tPA). The study hypothesis is that THR-18 will be safe and well tolerated in subjects suffering acute ischemic stroke and treated with Thrombolysis.

To adjust our forearm model for ischemia reperfusion injury, in order to used it for assessment of ischemia reperfusion damage in elderly and patients. To test the effect of ischemic postconditioning on ischemia reperfusion injury in healthy volunteers, using Annexin binding after repetitive handgripping.
