Atherosclerosis is responsible for the death of thousands of Americans each year. The carotid constriction model of plaque development has recently been presented as a model for unstable plaque formation in mice. In this study we 1) validate ultrasound biomicroscopy (UBM) for the determination of carotid plaque size, percent stenosis, and plaque development in live animals, 2) determine the sen...
PURPOSE To assess whether carotid plaque hemorrhage depicted with magnetic resonance (MR) imaging was associated with thromboembolic activity as assessed with transcranial Doppler imaging. MATERIALS AND METHODS The local research ethics committee approved the study, and all patients gave informed written consent. Between April 2005 and December 2006, patients with high-grade symptomatic carot...
Background: The value of noninvasive assessment of carotid plaque composition in identifying patients with high coronary risk remains elusive. We sought to determine whether and which carotid plaque components are associated with prior coronary events independent of traditional risk factors and plaque burden. Methods: Asymptomatic subjects with 50-79 % carotid stenosis by ultrasound were imaged...
INTRODUCTION Majority of stroke is due to ischemic infarction and occurs in carotid artery territory. The extra cranial parts of carotid arteries are the common sites for the atherosclerotic plaque formation. Ultrasonography is the first line of investigation for screening of the carotid artery diseases to localize and characterize the plaques. Objective was to study the morphological changes i...
BACKGROUND To investigate the impacts of carotid plaque and intima-media thickness (IMT) on future vascular events (VEs) in the patients with acute ischemic stroke. METHODS A total of 479 consecutive Korean patients with acute ischemic stroke were divided into 2 groups according to development of VEs; VE group (65.4 ± 10.9 years) vs no VE group (62.8 ± 13.2 years). VEs were defined as the dev...
INTRODUCTION AND OBJECTIVES The traditional Framingham score underestimates cardiovascular risk in certain populations. Extending its time-scale to 30 years and assessing its relationship with the presence of carotid atherosclerotic plaque may improve risk stratification. The objectives were: a) to determine the percentage of patients previously classified with the traditional score who were re...
BACKGROUND AND PURPOSE Few family studies reported moderate genetic impact on the presence and scores of carotid plaques. However, the heritability of carotid plaque characteristics remains still unclear. Twin studies more reliably estimate the relative contribution of genes to these traits in contrast to family study design. METHODS One hundred ninety-two monozygotic and 83 dizygotic adult t...
