Filter by:Carotid plaque burden and composition features, particularly lipid necrotic core, are significantly associated with severity of CAD stenosis. This study aims to explore the relationship between various phenotypic patterns of carotid atherosclerosis with the prevalence, phenotype, and severity of coronary atherosclerosis. The patients with chest tightness or chest pain will receive carotid artery ultrasonography before coronary angiography so as to explore the relationship between them.
Participants are being recruited at the inpatient department of the National Medical Research Center of Cardiology on a 'all-comers' basis. The enrolled participants will be divided into the main group (diagnosed with atherosclerotic cardiovascular disease (ASCVD)) and control (not diagnosed with ASCVD). The participants will have whole blood and serum collected at enrollment for further biobanking. A genome-wide association study will be carried out to determine the genetic determinants associated with atherosclerosis, coronary heart disease, acute coronary syndrome, etc., including a search for pathogenic variants.
Atherosclerosis is the main cause of cardiovascular diseases and is characterized by the progressive accumulation of lipids and inflammatory cells such as macrophages and lymphocytes within the vessel wall of large and medium-sized arteries, forming the so-called "atherosclerotic plaques". The formation process of these lesions is different depending on the age, genetics and physiological state of the individual affected. Furthermore, behavioral factors and the lifestyle of each individual play a key role, which can lead to the presence of a series of pro-atherosclerotic pathologies and risk factors, such as in particular systemic arterial hypertension, dyslipidemia, hyperglycemia and cigarette smoking. However, the precise molecular mechanisms underlying this pathogenetic process are still under investigation. The results of a study conducted in the past in collaboration between the U.O. have recently been published. of Vascular Surgery and the laboratory of Dr. I. Zucchi of the Institute of Biomedical Technologies of the CNR of Milan Segrate (Protocol GEMMA NUOVA, 16/int/2016), which describes that the overexpression of a newly identified gene (TMEM230) it may have a role in the formation of atherosclerotic vascular disorders, but it is still unclear how the expression of this gene is modulated in vivo. Knowledge of these factors would increase the knowledge of the molecular mechanisms underlying atherosclerosis and could represent a possible target for prevention and targeted pharmacological treatment, with consequent potential reduction in disability or mortality from cardiovascular diseases.
The goal of this prospective diagnostic accuracy cohort study is to compare the accuracy of carotid atherosclerotic plaques stiffness assessed by shear wave elastography (SWE) with greyscale median values (GSM), magnetic resonance imaging (MRI) and histopathological findings in patients with carotid atherosclerotic plaques causing stenosis above 50%, symptomatic or not. The main question it aims to answer is: is the plaque stiffness correlatable with GSM values, MRI findings or histopathological findings? Participants will be subjected to a vascular ultrasound study in which the SWE and GSM will be assessed. The second imaging modality for stenosis confirmation will be MRI and patients with confirmed symptomatic stenosis above 50% or assymptomatic stenosis above 70% will be considered for surgery intervention (endarterectomy or angioplasty). Patients that undergo endarterectomy will have the carotid plaques subjected to a histopathological study. The study will not arbitrate about the treatment decision.
This study is a prospective, multi-center, randomized controlled study, which evaluates the effectiveness and safety of cold laser plaque ablation for lower limb arterial stenosis and occlusive lesions from intermittent claudication to chronic threatening limb ischemia.
the goal of this interventional study is to compare between the conventional and the Eversion techniques in performing carotid endarterectomy in patients with carotid artery stenosis the main question it aim to answer is which technique is much more safe and effective the participants will have carotid endarterectomy by one of the two techniques the researcher will compare the group subjected to conventional carotid endarterectomy and the group subjected to Eversion carotid endarterectomy to see which technique is more effective and safe
A growing number of patients develop atherosclerotic cardiovascular disease (ASCVD) despite the absence of standard modifiable risk factors (SMuRF-less). There is scarcity of studies that address this issue in the Middle Eastern population.
This multicenter prospective cohort study aims to compare the difference in the effects of medical treatment within 1 year between the two groups of ICAS patients divided hemodynamically by Magnetic Resonance Fractional Flow Reserve. PC MRA will be applied for FFR measurement. The primary outcome is the composite of ischemic stroke or death related to the qualifying artery territory for 1 year.
The present study is a prospective randomized clinical trial aimed to compare the therapeutic strategy of angiography-guided versus concurrent OCT/FFR-guided intervention in patients with coronary artery disease.
In this Randomized Controlled Trial (RCT) we want to study the effect of an oil with high concentrations of cetoelic acid (C22:n1-11) (intervention) compared to supplements with a low concentration of cetoleic acid (control), but with equivalent content of EPA og DHA, on plasma levels of epa and dha as well as atherosclerotic markers, glucose, c-peptide and triglycerides in a patient group with a metabolically unfavorable phenotype. Our primary endpoints are changes in the concentration of EPA and DHA in plasma.
