In several common study designs, regression modeling is complicated by the presence of censored covariates. Examples of such covariates include maternal age of onset of dementia that may be right censored in an Alzheimer's amyloid imaging study of healthy subjects, metabolite measurements that are subject to limit of detection censoring in a case-control study of cardiovascular disease, and progressive biomarkers whose baseline values are of interest, but are measured post-baseline in longitudinal neuropsychological studies of Alzheimer's disease...

PURPOSE OF REVIEW: Abdominal obesity, especially the increase of visceral adipose tissue (VAT), is closely associated with increased mortality related to cardiovascular disease, diabetes, and fatty liver disease. This review provides an overview of the recent advances for abdominal obesity measurement. RECENT FINDINGS: Compared to simple waist circumference, emerging three-dimensional (3D) body-scanning techniques also measure abdominal volume and shape. Abdominal dimension measures have been implemented in bioelectrical impedance analysis to improve accuracy when estimating VAT...

OBJECTIVE: Thoracic endovascular aortic repair (TEVAR) with supra-aortic debranching has recently been introduced as a treatment option for aortic arch disease. Although less invasive than open repair, TEVAR is associated with a risk of perioperative embolic stroke due to dislodgment of atherosclerotic plaque debris, especially in individuals with atheromatous degeneration of the aortic lumen. It is difficult to determine atheroma vulnerability, and there is no current method for predicting the risk of atheroembolism...

BACKGROUND: Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital coronary anomaly. The enlarged right coronary artery provides retrograde collaterals to supply the left ventricle then preferentially directs into the lower pressure pulmonary artery system causing coronary steal phenomenon. Few patients who survive through adulthood without surgery must have abundant, well-formed functioning collaterals with adequate perfusion of the left ventricle...

Background: Bicuspid aortic valve (BAV) is the most common congenital heart disease, affecting 0.5%-2% of the general population. It is associated not only with notable valvular risk (aortic stenosis and/or regurgitation, endocarditis) but also with aortopathy with a wide spectrum of unpredictable clinical presentations, including aneurysmal dilation of the aortic root and/or ascending thoracic aorta, isthmic coarctation, aortic dissection, or wall rupture. Methods: The REgistro della Valvola Aortica Bicuspide della Società Italiana di ECocardiografia e CArdiovascular Imaging is a retrospective (from January 1, 2010)/prospective, multicenter, observational registry, expected to enroll 3000 patients with definitive diagnosis of BAV made by transthoracic and/or transesophageal echocardiography, computed tomography, cardiovascular magnetic resonance, or at surgery...

OBJECTIVES: This study sought to compare early emergency department (ED) use of coronary computed tomography angiography (CTA) and stress echocardiography (SE) head-to-head. BACKGROUND: Coronary CTA has been promoted as the early ED chest pain triage imaging method of choice, whereas SE is often overlooked in this setting and involves no ionizing radiation. METHODS: The authors randomized 400 consecutive low- to intermediate-risk ED acute chest pain patients without known coronary artery disease and a negative initial serum troponin level to immediate coronary CTA (n = 201) or SE (n = 199)...

Familial hypercholesterolemia (FH) is a genetic disease associated with persistently elevated levels of low-density lipoprotein cholesterol (LDL-C), which ultimately leads to greatly increased rates of atherosclerosis and cardiovascular disease. Atherosclerosis progression can be clinically approximated through measurement of coronary artery calcification (CAC). CAC can be measured via electron beam computed tomography (EBCT), multi-slice computed tomography (MSCT), or contrast-enhanced CT coronary angiography (CTCA)...
