PURPOSE Coronary artery calcification (CAC) scores are widely used to determine risk for Coronary Artery Disease (CAD). A CAC score does not have the diagnostic accuracy needed for CAD. This work uses a novel efficient approach to predict CAD in patients with low CAC scores. MATERIALS AND METHODS The study group comprised 86 subjects who underwent a screening health examination, including lab...
The purpose of this study was to find the circulating microRNAs (miRNAs) co-related with the severity of coronary artery calcification (CAC), and testify whether the selected miRNAs could reflect the obstructive coronary artery disease in symptomatic patients. Patients with chest pain and moderated risk for coronary artery disease (CAD) were characterized with coronary artery calcium score (CAC...
OBJECTIVES The aim of this study was to assess the relationship of the extent of subclinical atherosclerosis measured by coronary artery calcification (CAC) to the extent of second-hand tobacco smoke (SHTS) exposure in asymptomatic people who never smoked. BACKGROUND An association between SHTS and CAC was recently reported in a single study, but the quantitative aspects of the relationship a...
BACKGROUND Current guidelines recommend the use of coronary artery calcium (CAC) scoring for intermediate-risk patients; however, the potential role of CAC among individuals who have no risk factors (RFs) is less established. We sought to examine the relationship between the presence and burden of traditional RFs and CAC for the prediction of all-cause mortality. METHODS AND RESULTS The study...
BACKGROUND AND OBJECTIVES The Joint Commission introduced 3 Children's Asthma Care (CAC 1-3) measures to improve the quality of pediatric inpatient asthma care. Validity of the commission's measures has not yet been demonstrated. The objectives of this quality improvement study were to examine changes in provider compliance with CAC 1-3 and associated asthma hospitalization outcomes after full ...
INTRODUCTION In cross-sectional studies, patients with rheumatoid arthritis (RA) have higher coronary artery calcium (CAC) than controls. However, their rate of progression of CAC and the predictors of CAC progression have heretofore remained unknown. METHODS Incidence and progression of CAC were compared in 155 patients with RA and 835 control participants. The association of demographic cha...
BACKGROUND AND AIMS Inflammatory biomarkers and adipocytokines (IBA) may contribute to atherosclerosis by promoting vascular inflammation. The association between IBA and coronary artery calcium (CAC), a marker of subclinical atherosclerosis, is not well defined in South Asians (SA). We hypothesized that IBA (high sensitivity C-reactive protein [hsCRP], tumor necrosis factor alpha [TNF-α], adip...
In this article we present an optimal Markov Decision-based Call Admission Control (MD-CAC) policy for the multimedia services that characterize the next generation of wireless cellular networks. A Markov decision process (MDP) is used to represent the CAC policy. The MD-CAC is formulated as a linear programming problem with the objectives of maximizing the system utilization while ensuring cla...
Long-Term Prognosis After Coronary Artery Calcium Scoring Among Low-Intermediate Risk Women and Men.
BACKGROUND Cardiovascular screening of women using traditional risk factors has been challenging, with results often classifying a majority of women as lower risk than men. The aim of this report was to determine the long-term prognosis of asymptomatic women and men classified at low-intermediate risk undergoing screening with coronary artery calcium (CAC) scoring. METHODS AND RESULTS A total...
Human cord blood progenitor-derived erythroblasts have recently been shown to respond to erythropoietin (Epo) or granulocyte-macrophage colony-stimulating factor (GM-CSF) with a transient increase in intracellular free calcium concentration [Cac]. However, the importance of [Cac] changes in mediating cell proliferation and/or differentiation is undefined. In the present study, the response of e...
