Active clinical trials for "Ischemia"

Subjects from the AG-CLI-0206 phase 3 study that received AMG0001 will be eligible for the AG-CLI-0206-LTFU study

This prospective, randomized, single-center clinical trial is designed to figure out the most optimal algorithm of remote ischemic conditioning on patients with chronic cerebral ischemia.

Few early prognostic indicators are currently available for patients' families and clinicians following out of hospital cardiac arrest (OHCA), and blood biomarkers may be of prognostic value in these cases. Brain tissue is highly dependent upon aerobic respiration, and oxygen deprivation result in irreversible neuronal cell injury. Peptides released into the blood by injured neuronal cells can be measured to estimate degree of injury, and potentially predict long term neurological outcome.

Ischemic stroke occurs when an artery to the brain is blocked. If the artery remains blocked for more than a few minutes, the brain cells may die. This is why immediate medical treatment is critical. Luotai® is the brand name of Panax notoginseng finished product. 2 kinds of formulation are available, the lyophilized powder for Injection and gelatin based soft capsule. They are being used for decreasing incidence of cerebral infarction or ischemic stroke. This study will be conducted as an observational study, regarding the safety, effectiveness of Luotai treatment in acute ischemic stroke patients. This study will be carried out in approximately 360 patients with acute stroke in 6 hospitals in Vietnam - Bạch Mai Hospital, 108 Military Hospital, 103 Military Hospital, Trung Vuong Hospital, Phu Tho General Hospital, 115 Hospital. STUDY PROCEDURES: Participants will be enrolled in an unbiased manner (by consecutive sampling) and consecutive sampling method. The investigators will record participants' information required by the Case Report Form. The study which last for about 3 months, and in each of the visit, the information will be collected includes informed consent, demographic data, ischemic stroke assessment, concomitant medication, adverse reactions. A travel transportation allowance of VND 300,000 will be given for each visit. Participants will receive Luotai and other medications according to the local hospital practice in accordance with the terms of the local marketing authorization in Vietnam. The recommended dosage of Luotai is: Luotai™ injectable lyophilized powder for consecutive 14 days, Luotai soft capsules for 65 days. The participation of the study is fully voluntarily. Patients decide not to participate in the study will not be disadvantaged in any way. All collected information from participants is protected as confidential. The results of the study may be published in medical literature, but participants will not be identified. This study does not include any procedure/test that there were not indicated according to local clinical practice. There is no specific associated risks or discomforts in this study related to the participation. The results of this research may guide in further understanding the Ischemic Stroke.

This study is a prospective, open-label, multi-center, registry study, designed to show that rescue stenting is safe and effective for emergency large vessel occlusion (ELVO) patients who have mechanical thrombectomy failure. Participants with ELVO will initially underwent mechanical thrombectomy usig stent retriever, contact aspiration or both. After failure of mechanical thrombectomy, rescue stenting will be performed.

Temporary cardiac support by VA-ECLS can lead to lower limb ischemia. The aim of this study is to evaluate a multi-modal strategy (physical examination, NIRS monitoring and angiography through the reperfusion canula) of lower limb surveillance.

The Pedra Technologies' PedraTM device is a non-invasive, diagnostic device intended to measure foot perfusion by assessing blood flow. The PedraTM device comprises a compact instrument console connected to a sensor that is pasted onto the patient's foot during perfusion assessment. Through skin contact, the device is able to monitor tissue perfusion at depths of up to 7.5mm. The monitor console contains opto-electronic instrumentation including coherent infrared light sources, photo detectors, and display/control electronics. The sensor comprises passive fiber-optic conduits, which transfer infrared light from the console to the patient, and relays scattered light from the patient back to the console. The intensity of light emitted from the sensor is less than 3 mW, well within the safety envelope of Class I laser systems and comparable (or lower than) other commercially available devices such as laser Doppler systems. The sole point of contact with the patient is a layer of medical grade adhesive tape, which is used to paste the flat sensor onto intact skin.

The first aim of this study is to investigate the frequency and severity of a specific pathological metabolic pattern, mitochondrial dysfunction, of the brain in comatose patients under neurocritical care. This pattern is recognized as a complication after compromised blood flow to the brain and may be amenable to treatment. The other main aim of this study is to correlate patterns of metabolites between brain and jugular venous blood. It is probable but not proven that jugular venous microdialysis can mirror the global metabolic state of the brain.

Ischemic strokes are one of the leading causes of handicap and death in elderly people in France. Cognitive reserve (CR) is an active model, defined as a function of lifetime intellectual activities and other environmental factors that explain differential susceptibility to functional impairment in the presence of pathology or other neurological insult. CR is estimated using variables for cognitive activity: years of education, professional status, socioeconomic status… Furthermore, brain reverse (BR) is a passive and quantitative model that depend on brain size and other quantitative aspects of the brain that explain differential susceptibility to functional impairment in the presence of pathology. Firstly, volume and localization of ischemic strokes have a great impact on CR and BR due to brain injury. On the other hand, CR influences the severity and the expression of cognitive diseases. The investigators realize a prospective study in order to assess the impact of CR and BR on cognitive prognosis after a right middle cerebral artery ischemic stroke in elderly patients.

This study compares differences in hemodynamic ve ECG parameters of patients undergoing urological or orthopedic surgery under spinal anesthesia. First group will comprise of patients undergoing surgery in the morning hours; thus with a standard fasting duration (8 hours), and the second group will comprise of patients undergoing surgery afternoon; thus having a prolonged fasting duration (>12 hours).
