Filter by:Hypoxic-ischaemic brain injury (HIBI) is the main cause of death in patients who are comatose after resuscitation from cardiac arrest. Current guidelines recommend to target a mean arterial pressure (MAP) above 65 mmHg to achieve an adequate organ perfusion. Moreover, after cardiac arrest, cerebral autoregulation is dysregulated and cerebral blood flow (CBF) depends on the MAP. A higher blood pressure target could improve cerebral perfusion and HIBI. Transcranial Doppler (TCD) is a non-invasive method to study CBF and its variations induced by MAP. The aim of this study is to test the feasibility of an early-goal directed hemodynamic management with TCD during the first 12 hours after return of spontaneous circulation (ROSC).
Thoracic endovascular repair (TEVAR) and transcatheter aortic valve implantation (TAVI) are standard of care procedures to treat thoracic aortic aneurysm or severe aortic stenosis, respectively. Both procedures have a high risk of stroke and silent infarction. Gas has been detected in the cerebral vasculature during these procedures and associated with DWI positive lesions on MRI. The hypothesis is that air emboli contribute to stroke and silent infarction. The investigators propose addressing air emboli by flushing the device with carbon dioxide prior to flushing with saline. This is a pilot study comparing standard saline flush alone to carbon dioxide flushing with saline flush.
A randomized clinical trial for the comparison of the efficacy and safety of moderate-intensity rosuvastatin plus ezetimibe versus high-intensity rosuvastatin for target LDL-C goal achievement in patients with recent ischemic stroke
TACT3a is a double blind, placebo-controlled, randomized trial to test a novel therapy, edetate disodium-based chelation of environmentally acquired toxic metals, to reduce cardiovascular events including amputation in high-risk diabetic patients.
Aim of the study is to evaluate the usefulness of interleukin 33 in the blood plasma in patients with the acute ischemic stroke of the brain in relation to mode of treatment (thrombolysis, thrombectomy, no treatment), risk factors in correlation with other inflammatory state markers (hsCRP, morphology with smear ). Blood is collected on the first and seventh days of stroke. The purpose is to clarify utility of IL 33 as a biomarker of acute stroke.
Aim of the study is assessment the prevalence of the low ankle-brachial index (ABI) defined less than or equal 0.9 in patients with acute cerebral ischemic event (stroke or transient ischemic attack) and determinate the correlation between ABI and internal carotid artery stenosis (ICAS) in the acute cerebral ischemic patients. The low ABI is a strong marker of generalized atherosclerosis. LEAD is a strong independent predictor for stroke.
The purpose of this study is to assess the safety and efficacy of glucagon-like peptide-1 (GLP-1) analogue liraglutide in the treatment of acute minor stroke (National Institute of Health stroke scale, NIHSS ≤ 3) or high-risk transient ischemic attack (TIA) (ABCD2 score ≥ 4 ) patients with type 2 diabetes mellitus.
Early mobilization was thought to be effective in patients with acute ischemic stroke. As the essential component of stroke unit care, early mobilization has already been part of routine clinical practice. However, it is uncertain that which and when medical service focusing on functional recovery should be delivered after the emergency interventions for stroke. Besides, the optimal time window, for delivering early mobilization after acute ischemic stroke, has not been verified with strong evidence.
The aim of the study is to find a radiological biomarker of Transient Ischemic Attacks (TIA) thanks to functional Magnetic Resonance Imaging (fMRI) done within the 24 hour after symptoms onset.
In patients undergoing planned surgery for carotid tromendarterendectomy, a non-invasive device that registers heart rate variability is attached. Furthermore a non-invasive device that monitors cerebral oxygenation- near infrared spectroscopy as well as electroencephalography is also attached. At times when surgeons clamps the carotid artery, there will be a moment with controlled cerebral ischemia. This will be registered by the devices. The information obtained will be used to teach artificial intelligence what patterns are related to cerebral ischemia. The same procedure will be performed in patients undergoing ocklusive cerebral trombectomy, so the artificial intelligence will learn to recognize cerebral reperfusion.Blood samples will be drawn before and after cerebral ischemia may occur and will be analyzed for neurobiomarkers and cardiac biomarkers. To teach the algorithm patterns from anaesthesia and surgery in patients without pre existing neuronal injury, the same method will be applied to patients undergoing mixed abdominal surgery. This group will provide a better knowledge of neuro biomarker patterns during anesthesia and surgery.
