BACKGROUND Speckle tracking echocardiography (STE) has a unique feature of angle independence and, thus, may provide a powerful means of assessing left ventricular (LV) torsion (LVtor). The aims of this study were to assess: (1) the feasibility of 2-dimensional STE in the measurement of LVtor; and (2) the relationship of LVtor with age and conventional(More)
UNLABELLED Nonalcoholic fatty liver disease (NAFLD) is related to risk factors of coronary artery disease, such as dyslipidemia, diabetes, and metabolic syndrome, which are closely linked with visceral adiposity. The aim of this study was to investigate whether NAFLD was associated with coronary artery calcification (CAC), which is used as a surrogate(More)
BACKGROUND Inverse correlations of high serum bilirubin with metabolic and cardiovascular disease have been suggested. However, anti-atherogenic effects of bilirubin have not been well-established in terms of the presence of plaques and stenosis identified in coronary computed tomography (CT). METHODS A cross-sectional study was conducted on 2862 men who(More)
BACKGROUND Metabolic syndrome (MetS) is related with left ventricular diastolic dysfunction (LVDD) and poor cardiovascular outcome. Epicardial adipose tissue (EAT) thickness, measured by echocardiography, is increased in subjects with MetS. However, the association of EAT with LV diastolic function has not been evaluated in subjects with MetS. METHODS In(More)
The incidence of diastolic heart failure increases dramatically with age. We investigated the impact of long-term exercise training on age-related diastolic dysfunction. Old (25-month-old) male Fischer 344 rats were studied after 12 weeks of treadmill exercise training or sedentary cage life (N=7, in each group). We determined cardiac performance using a(More)
BACKGROUND/AIMS Non-alcoholic fatty liver disease (NAFLD) is closely associated with abdominal obesity, dyslipidemia, hypertension, and Type 2 diabetes, which are all features of the metabolic syndrome. The aim of the present study was to elucidate whether NAFLD is associated with carotid atherosclerosis. METHODS The study population comprised 659(More)
Proper neuronal function requires tight control of gene dosage, and failure of this process underlies the pathogenesis of multiple neuropsychiatric disorders. The SHANK3 gene encoding core scaffolding proteins at glutamatergic postsynapse is a typical dosage-sensitive gene, both deletions and duplications of which are associated with Phelan-McDermid(More)
AIM The cardio-ankle vascular index (CAVI) reflects overall arterial stiffness from the aorta to the ankle, independent of blood pressure. We aimed to investigate the association of fat burden assessed by visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT) and epicardial adipose tissue (EAT) with CAVI in an asymptomatic population. METHODS A(More)
OBJECTIVE The association between arterial stiffness, as measured by the cardio-ankle vascular index (CAVI), and coronary atherosclerosis, using coronary artery computed tomography (CT), was investigated in the asymptomatic general population, with special interest in subjects with abnormal glucose metabolism. PATIENTS AND METHODS A total of 158(More)
OBJECTIVES Non-alcoholic fatty liver disease (NAFLD) is known to be related to factors that predict the development of coronary heart disease (CHD), such as dyslipidemia, central obesity, and metabolic syndrome (MS). The aim of this study was to determine whether individuals with NAFLD have an elevated risk of CHD, as estimated using the Framingham risk(More)
