PURPOSE To determine the relationship of pericardial fat, which secretes proinflammatory markers that have been implicated in coronary atherosclerosis, with atherosclerotic plaque in an asymptomatic population-based cohort. MATERIALS AND METHODS In this institutional review board-approved study, all participants supplied written informed consent. One(More)
OBJECTIVES The purpose of this study was to assess coronary arterial remodeling as a marker of subclinical atherosclerosis using coronary wall magnetic resonance imaging (MRI) in an asymptomatic population-based cohort. BACKGROUND In early atherosclerosis, compensatory enlargement of both the outer wall of the vessel as well as the lumen, termed(More)
BACKGROUND Growing evidence suggests that vitamin D deficiency Is associated with clinical coronary artery disease (CAD). The relationship between vitamin D deficiency and subclinical CAD in HIV-infected individuals is not well-characterized. METHODS Computed tomographic (CT) coronary angiography was performed using contrast-enhanced 64-slice(More)
BACKGROUND Protease inhibitors (PIs) may be associated with accelerated atherosclerosis in individuals infected with human immunodeficiency virus (HIV). We assessed the effects of HIV PIs on subclinical atherosclerosis. METHODS The lipid profiles, C-reactive protein (CRP) levels, coronary artery calcification (CAC) scores, and blood cell morphologic(More)
hree-dimensional shapes are used extensively in fields such as mechanical design, multimedia games, architecture, and medical diagnosis. 1 All of these applications need to store, recognize , and retrieve 3D models effectively and automatically. Because the characteristics of 3D shapes differ from those of text and images, traditional classification and(More)
Deep learning has emerged as a powerful technique to extract high-level features from low-level information, which shows that hierarchical representation can be easily achieved. However, applying deep learning into 3D shape is still a challenge. In this paper, we propose a novel high-level feature learning method for 3D shape retrieval based on deep(More)
UNLABELLED Chronic cocaine use may lead to premature atherosclerosis, but the prevalence of and risk factors for coronary artery disease (CAD) in asymptomatic cocaine users have not been reported. The objective of this study was to examine whether vitamin D deficiency is associated with the development of CAD in human immunodeficiency virus (HIV)-infected(More)
PURPOSE To evaluate the use of coronary wall MRI as a measure of atherosclerotic disease burden in an asymptomatic population free of clinical cardiovascular disease. Coronary wall magnetic resonance imaging (MRI) is a noninvasive method for evaluation of arterial wall remodeling associated with atherosclerosis. MATERIALS AND METHODS Asymptomatic(More)
BACKGROUND Stroke remains a leading cause of death in the United States. While stroke-related mortality in the USA has declined over the past decades, stroke death rates are still higher for blacks than for whites, even at younger ages. The purpose of this study was to estimate the frequency of a lipid core and explore risk factors for its presence in(More)
BACKGROUND Premature coronary artery disease (CAD) is a major concern in human immunodeficiency virus (HIV)-infected African Americans. The objectives of the study were to estimate the incidence of subclinical CAD, defined by the presence of coronary plaque and/or calcification on cardiac computed tomography (CT), and to identify the associated risk factors(More)
