Subclinical inflammation plays a critical role in all stages of the atherosclerotic process, from the initiation of the fatty streaks to the development of plaque instability and rupture, causing myocardial ischemia and acute coronary syndromes (ACS). A few studies have suggested that the autonomic nervous system (ANS) and the inflammatory response are intimately linked. Accordingly, a relation between impaired cardiac autonomic tone and increased markers of inflammation has been reported in healthy subjects as well as in patients with type 1 diabetes mellitus, chronic coronary syndrome or decompensated heart failure. To get insight in the controversial relationship between cardiac autonomic dysfunction and inflammation in patients with ACS both with and without obstructive CAD and assess the precise mechanisms and molecular pathways by which these two pathophysiological conditions mutually influence each other, to characterize their prognostic implications and identify possible targets for novel therapeutic strategies.
The study will evaluate the safety and efficacy of Peripheral Intravascular Lithotripsy system with Shockwave S4 catheter® for the treatment of de novo, re-stenosis or re-occlusive,calcified chronic total occlusion (CTOs) lesions in patients with Critical Limb Threatening Ischemia (CLTI).
This trial is a single-center, prospective, observational clinical study. All patients who have at least one coronary artery stenosis of 30%-90% in diameter ≥ 2mm confirmed by CCTA, and who are scheduled to undergo clinically indicated invasive coronary angiography (ICA) and optical coherence tomography (OCT) evaluation and/or treatment will be eligible for enrollment. We proposed a novel approach that integrates CCTA, ICA and OCT images to automatically measure plaque characterization and calculate CT-FFR using computational fluid dynamics (CFD) simulation and artificial intelligence deep learning.
This observational study aims to detect levels of iron, alpha-synuclein, and soluble lymphocyte activation gene 3 in acute ischemic stroke patients. And to see expressions of iron, alpha-synuclein, and lymphocyte activation gene 3 in the brain tissue of ischemic rats. The main questions it aims to answer are: - Is there an association between iron and alpha-synuclein accumulation in ischemic stroke? - Is there any change in soluble lymphocyte activation gene levels in ischemic stroke and if these levels are related to stroke severity and infarction size? . Can soluble lymphocyte activation gene levels be used as an early biomarker to diagnose ischemic stroke?
The trial is prospective, randomized, open-label, blinded endpoint (PROBE) design. Patients with acute ischemic stroke, who are eligible for standard intravenous thrombolysis within 4.5 hours of stroke onset will be randomized 1:1 to 0.25mg/kg or 0.9 mg/kg alteplase before all participants undergo endovascular thrombectomy.
The purpose of this study is to demonstrate the effectiveness and safety of CVA-FLOW, a digital health AI based Telestroke system developed by CVAID Ltd. Company aims to assist certified medical staff to triage acute ischemic stroke patients using dedicated algorithms in order to support application for market approval for CVA-FLOW device.
The purpose of this study is to determine the efficacy and safety of levofloxacin combined with intravenous thrombolysis in treating acute ischemic stroke
This is a multicentre, parallel-group, randomised, sham-controlled, observer blinded trial, assessing the efficacy of remote ischemic preconditioning on preventing myocardial injury after noncardiac surgery.
To establish if the cardiac radiation dose assesment is well aproximated with routine 3D CT scan compared to 4D CT experimental scan with respiratory gating (breath motion monitoring). The study population relates to left side breast cancers female patients that require a radiation therapy treatment.
