The aim of this study was to evaluate the relationship between coronary artery calcium score (CACS) assessed by multidetector computed tomography (MDCT) and plaque components assessed by virtual histology-intravascular ultrasound (VH-IVUS) in 172 coronary artery disease (CAD) patients with 250 coronary lesions. CACS was assessed according to Agatston scoring method by MDCT and patients were div...
Coronary artery calcium (CAC) is a significant marker of atherosclerosis and cardiovascular events. In this work we present a system for the automatic quantification of calcium score in ECG-triggered non-contrast enhanced cardiac computed tomography (CT) images. The proposed system uses a supervised deep learning algorithm, i.e. convolutional neural network (CNN) for the segmentation and classi...
To determine in patients with abdominal aortic aneurysm (AAA) the coronary calcium burden and prevalence of coronary artery disease (CAD) in relation to cardiovascular risk factors, and to assess the left ventricular (LV) function using cardiac computed tomography (CT). Sixty consecutive patients (six females; 72.2+/-9.0 years) with AAA underwent dual-source CT calcium scoring and coronary angi...
The primary use of coronary artery calcium scoring has been in its ability to predict coronary artery disease (CAD) events in generally asymptomatic patients and to provide incremental risk stratification beyond the use of traditional clinical risk factor assessment. Thresholds of calcium burden, as determined by the area-density scoring or Agatston scoring method, on the basis of age, sex, and...
background: myocardial infarctions at different locations have been related to different sets of risk factors. this study was designed to examine the association between cardiovascular risk factors and specific coronary artery calcification (cac). methods: the study population comprised 573 postmenopausal women selected from a population-based cohort study. established vascular risk factors wer...
OBJECTIVES We sought to determine the prognostic accuracy of electron beam computed tomographic (EBCT) scanning of the coronary arteries at three to four years. BACKGROUND Coronary artery calcium scores determined by EBCT correlate with the severity of coronary artery disease. However, previous reports of the prognostic accuracy of EBCT scanning for coronary events in asymptomatic individuals...
