View clinical trials related to Carotid Plaque.
Filter by:Carotid ultrasonography has been proposed as a tool for prediction of future cardiovascular disease (CVD). Nevertheless, its role in clinical practice remains controversial. Methods: The investigators analyse the incidence of CVD and mortality in a cohort of 1004 participants without preexisting CVD according to a simple plaque scale recorded in different segments of the carotid artery assess by ultrasound. A prognostic tool for CV events was development adding Carotid Plaque-Burden (CPB) scale to the Systematic COronary Risk Evaluation (SCORE2) table (CPB- SCORE2 scale).
This multicenter study involved 5 hospitals (Changhai Hospital; Yueyang Hospital of Shanghai University of Traditional Chinese Medicine; Gongli Hospital; Putuo Hospital of Shanghai University of Traditional Chinese Medicine; No. 904 Hospital of the PLA Joint Logistics Support Force Wuxi). The study enrolled 5000 consecutive patients without known CAD who underwent first coronary angiography for stable chest pain and carotid ultrasound was performed during hospitalization from January 2017 through December 2018.
The goal of this observational study is to validate the diagnostic performance of photon counting/spectral CT to distinguish tissue components in ischemic stroke with MRI/semi-automated segmentation software and histology as the reference standard. The main question[s] it aims to answer are: 1. Presence or absence of calcium, hemorrhage, and lipid plaque components as determined on CT will be confirmed with carotid MRI, segmentation quantitative (e.g., volume) output from segmentation software, or histologic staining. 2. Volumes of hemorrhage, lipid, and calcium components will be measured to determine plaque phenotype and correlated with ipsilateral intracranial stroke burden. Participants will be asked to do the following: Aim 1: - 1 Research Carotid/Neck MRI of the carotid arteries - 1 Photon counting/spectral CT angiography of the neck Aim 2: - 1 Research Carotid/Neck MRI of the carotid arteries - 1 Photon counting/spectral CT angiography of the neck - 1 Carotid plaque tissue from participants surgery will be retrieved, imaged, and stained
1. The purpose of this study is to detect the differences of carotid atherosclerosis severity between patients with or without OSAHS(Obstructive Sleep Apnea and Hypopnea Syndrome) in a cross-sectional study in a large sample. 2. Then a longitudinal control study is conducted to observe the progress of the carotid atherosclerosis by vascular ultrasonography and the occurrence of cerebrovascular events after the intervention of the oral appliance for treating OSAHS，and finally explore the feasibility of using oral appliance to treat OSAHS in primary prevention of ischemic stroke.
It is well known that the Type 2 diabetes and vascular disease are preceded by over ten years by metabolic dysfunction and anatomic changes that can be quantified. In order to develop effective preventive strategies and reduce the cost burden to the health care system, recognition of the earliest pathophysiology of Type 2 diabetes and vascular disease is clinically relevant. The interval retrospective evaluation of data from patient records, reflect the effectiveness of the various treatments implemented in clinical practice. Prevalence of "prediabetes" among American adults is estimated to be ~84 million, or one out of three Americans. Over a 5-7 year period approximately one third of these prediabetic individuals will progress to type 2 diabetes. Prediabetes is a heterogenous group comprised of individuals with impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and increased A1c (5.7-6.4%). Although different pathophysiologies are present in individuals with IFG and IGT, their conversion rate to overt type 2 diabetes mellitus (T2DM) is similar. Insulin resistance is a common causal feature of many of the pathophysiologic mechanisms linking macrovascular disease and type 2 diabetes. Because hyperglycemia is the major factor responsible for the development of microvascular complications, it logically follows that prevention of progression of prediabetes to overt diabetes should retard/prevent the development of the microvascular complications. From the measurement of plasma glucose, insulin, and c-peptide levels during the oral glucose tolerance test, one can derive measures of the two core defects responsible for the development of T2DM, i.e. insulin resistance and beta cell dysfunction as well as the degree of dysglycemia. By combining a standard medical evaluation with the evaluation of cardiovascular biomarkers, patients at intermediate risk of vascular disease can be identified. In these patients, carotid intima media thickness (IMT) and carotid plaque evaluation is offered to attempt to clarify risk. The hypothesis of this observational study is that the characterization of the physiology and anatomy of patients at risk of developing type 2 diabetes and/or cardiovascular disease can stratify risk of developing disease and direct treatment strategies tailored to the identified physiologic defect, leading to improvements in the delay or prevention of disease.
