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)
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)
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)
OBJECTIVE Coronary artery wall magnetic resonance imaging (MRI) has been developed to assess coronary lumen diameter and wall thickness. The purpose of this study was to evaluate the physiological parameters that affect the measures of coronary wall thickness using black-blood MRI pulse sequences. METHODS Eighty-seven participants (38 men and 49 women) of(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)
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)
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)
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)
