Filter by:Aneurysmal subarachnoid haemorrhage is a complex pathology, the pathophysiology of which is still imperfectly understood. Its morbidity and mortality remain significant. In addition to the damage sustained by the brain in the immediate aftermath of aneurysmal rupture, which is inaccessible to life-saving treatment, a significant proportion of lesions occur at a distance from the initial event. Delayed cerebral ischaemia is one of the most morbid complications. It combines an inflammatory pattern with vascular dysfunction and neuronal excitotoxicity, leading to avoidable secondary neuronal loss. Vascular dysfunction is mediated by a loss of homeostasis between endothelial cells and figurative blood cells, including platelets. However, the interrelationship between these elements and the precise chronology of the dysfunction remain imperfectly described to date. It therefore seems appropriate to propose temporal monitoring of platelet activation kinetics over time, combined with concomitant collection of markers of endothelial damage, in order to clarify the vascular chronobiology of this pathology.
Along with the current clinical trial, the impact of adding atorvastatin or rosuvastatin in the first 24 hours on the clinical outcomes of first-ever large-vessel ischemic stroke patients treated with clopidogrel assessed through NIHSS, mRS, and possible adverse effects.
The purpose of this study is to determine if allogeneic Endothelial Progenitor Cells (EPCs) intravenous infusion to a subject with leg ulcer and/or gangrene due to poor blood flow will be safe and if it will relieve leg pain, increase blood flow, and/or cure the leg wound.
Analyzing changes in cerebral oximetry, transcranial Doppler and biomarkers of neuronal ischemic injury and blood-brain barrier integrity assessing the safety and efficacy of ischemic postconditioning in carotid surgery (IPCT).
Cerebral infarction is the second cause of death and the third cause of disability. More than 13.7 million patients worldwide are diagnosed with stroke every year, and the number of deaths is 5.5 million, of which ischemic stroke is the major type, accounting for 87%. Sequelae of stroke are problems that require long-term medical care. If we can intervene and assist with Traditional Chinese Medicine (TCM) at early stage, it will be a great boon for patients. In clinical practice, TCM collects data as the basis for diagnosis through the four diagnostic methods-look, listen, question, and feel the pulse. Among these, tongue diagnosis and pulse diagnosis belong to the categories of look and feel the pulse. At present, the objective examination instruments of TCM developed are mainly tongue diagnostic instruments and pulse diagnostic instruments. Therefore, we hope to utilize tongue and pulse diagnoses as the main reference to analyze the changes in ischemic stroke stages. The data of this study are collected from China Medical University Hospital and YuanRung Hospital-for further statistical analysis. Ischemic stroke patients (ICD-10: I63) who were hospitalized within 1 week from the date of diagnosis were eligible to join this research project. Tongue and pulse examinations were collected once per week within 1 month. A total of 4 tongue-pulse examinations were collected in each case, which were categorized into acute stage (24 hours to 1 week), subacute stage (1 to 3 weeks) and chronic stage (more than 3 weeks). [30] This research is to study the changes of tongue and pulse diagnoses in acute, subacute and chronic stages among ischemic patients who receive TCM diagnosis and treatment. Through utilizing objective evaluation of Chinese and Western medical examination instruments, we hope to establish clear diagnostic standards for TCM syndrome types, so as to evaluate the efficacy of clinical diagnosis and treatment. The goal is to improve the quality of TCM care and to provide Chinese and Western integrated treatment for stroke patients in the future. This research can also serve as a reference for related TCM research and development.
Coronary atherosclerosis is the most common cause of ischaemic heart disease. About 40-50% of patients with symptoms and documented ischaemia on non-invasive tests do not show obstructive coronary artery disease on coronary angiography. This cause of ischaemic heart disease called INOCA (Ischemic Non-Obstructive Coronary Artery), far from having a benign prognosis, is associated with an increase in major adverse cardiac events (MACE) as well as increased functional limitation. The current European Society of Cardiology clinical practice guidelines for the management of chronic coronary syndrome establish for the first time a IIa recommendation for the invasive analysis of coronary flow reserve (CFR) and microvascular resistance index (MRI) in symptomatic patients with INOCA. The acetylcholine (Ach) test, based on intracoronary (ic) administration, is established as indication IIb for the assessment of micro or macrovascular vasospasm in patients with suspected vasospastic angina (VSA) (4). A national multicentre registry would allow us to determine the prevalence of INOCA and its different endotypes in our setting.
The purpose of this study was to evaluate the effectiveness of early administration of BXOS110 for injection in reducing overall disability in patients with acute ischaemic stroke.
Peripheral artery disease (PAD), vascular disease of atheromatous origin, is a frequent pathology, with a steady and significant increase in prevalence over the last decades. It has various symptoms ranging from mild arterial claudication to critical limb ischemia. The critical ischaemia stage in PAD is defined by rest pain or trophic disorders and is a special situation because of the number of cardiovascular deaths at 1 year (25%), 60% at 5 years and acute ischaemic recurrence at 1 year (25%). It is a medico-surgical pathology. A haemodynamic marker is needed to monitor patients, as it is predictive of limb progression, cardiovascular events and mortality. The Systolic Rise Time (SRT) of the plantar footpad is a recently described haemodynamic measurement of proven value in the diagnosis of PAD. The aim of this study is to show the prognostic value of the Systolic Rise Time on Major Adverse Limb Events (MALE).
Phase III Clinical Trial of GD-11 for Injection in the Treatment of Acute Ischemic Stroke - A Multi-Center, Randomized, Double-Blind, Parallel, Placebo-Controlled Phase III Clinical Study with the primary objective of evaluation of the efficacy and safety of GD-11 for injection in the treatment of acute ischemic stroke patients within 48 hours. The subject has a clinical diagnosis of acute ischemic stroke, within 48 hours from stroke onset to start of study treatment, with a National Institutes of Health Stroke Scale (NIHSS) between 6 and 20, had a total score of upper and lower limbs on motor deficits ≥ 2. The primary outcome is the proportion of subjects with mRS score ≤ 1 at 90 days after treatment.
The principal aims of the clinical investigation involve assessing the safety profile and MTD of human forebrain neural progenitor cells (hNPC01) administered at escalated doses via single-dose intracerebral injection to subjects with stable chronic ischemic stroke.
