AIMS: Type 1 diabetic patients (T1DM) experience a higher cardiovascular disease and mortality risk than controls. We investigated whether visceral adipose tissue (VAT) contributes to coronary artery calcifications (CAC) and cardiac dysfunction in T1DM. METHODS: A cross-sectional study of 118 T1DM patients without a history of cardiovascular disease (men/women: 68/50, age 46±12years, HbA1c 7.6±0.9%, BMI 25.8±4.1kg/m2) was conducted. CAC and VAT were measured using a CT scan...

BACKGROUND: Ideal cardiovascular health (CVH) is associated with a lower risk of cardiovascular disease and freedom from coronary artery calcium (CAC). Prospective data on the association between maintenance of optimal CVH and the progression of subclinical coronary atherosclerosis are limited. We assessed the influence of unfavorable versus favorable CVH on the incidence of CAC progression. METHODS AND RESULTS: The study population consisted of 1119 FHS (Framingham Heart Study) participants who attended the serial FHS MDCT I and MDCT II study (Multi-Detector Computed Tomography) and had a zero Agatston CAC score at baseline...

BACKGROUND: The relationship between serum corrected calcium (CCa) level and vessel calcification at dialysis initiation and survival has seldom been evaluated. Therefore, we evaluated the efficacy of CCa levels and the calcification score at the initiation of dialysis for predicting all-cause and cardiovascular (CV) mortality in patients with end-stage renal disease (ESRD). METHODS: The study group included 407 patients with ESRD, who started hemodialysis between January 2009 and December 2016 at the Red Cross Ishinomaki Hospital...

OBJECTIVE: To assess the accuracy of an iterative reconstruction (IR) technique for coronary artery calcium scoring with reduced radiation dose. METHODS: 163 consecutive patients underwent twofold scanning by 320-row detector computed tomography (CT) at 120 kVp. A low-dose scan at 25% tube current but with standard scan length (14 cm) was followed by a standard dose scan with routine tube current but reduced scan length (10 cm). Reduced dose images were constructed using filtered back-projection (FBP) and IR (adaptive iterative dose reduction in 3 dimensions, or AIDR3D)...

INTRODUCTION: Cardiovascular events are common in people with aortic aneurysms. Arterial calcification is a recognised predictor of cardiovascular outcomes in coronary artery disease. Whether calcification within abdominal and thoracic aneurysm walls is correlated with poor cardiovascular outcomes is not known. PATIENTS AND METHODS: Calcium scores were derived from computed tomography (CT) scans of consecutive patients with either infrarenal (AAA) or descending thoracic aneurysms (TAA) using the modified Agatston score...

BACKGROUND AND OBJECTIVE: There is evidence of association between aging and increase in the normal upper limit of the common bile duct (CBD) diameter. As aging is a documented risk factor for atherosclerosis, and the possible effect that atherosclerosis can have on the CBD diameter via affecting its smooth muscle contractility and blood flow, we decided to determine the association between CBD diameter and atherosclerosis in the abdominal aorta (AA). METHODS: A total of 99 asymptomatic patients (53 males and 46 females; age range of 18-88 years) without history of cholecystectomy who underwent abdominal contrast-enhanced CT scan were included...

BACKGROUND AND AIMS: Several studies have reported a significant inverse association of light to moderate alcohol consumption with coronary heart disease (CHD). However, studies assessing the relationship between alcohol consumption and atherosclerosis have reported inconsistent results. The current study was conducted to determine the relationship between alcohol consumption and aortic calcification. METHODS: We addressed the research question using data from the population-based ERA-JUMP Study, comprising of 1006 healthy men aged 40-49 years, without clinical cardiovascular diseases, from four race/ethnicities: 301 Whites, 103 African American, 292 Japanese American, and 310 Japanese in Japan...

BACKGROUND: In transcatheter aortic valve replacement (TAVR), multi-detector row computed tomography (MDCT) is currently the standard imaging modality for correct prosthesis sizing, despite risks of radiation and contrast-induced renal injury. Three-dimensional (3D) transesophageal echocardiography (TEE) has been proposed as a potential alternative imaging technique, and recently, automated 3D transesophageal echocardiographic software (Aortic Valve Navigator [AVN], an unreleased prototype from Philips) has been developed for assessment of the aortic annulus and root...

BACKGROUND: Premenopausal women have fewer cardiovascular disease (CVD) events than postmenopausal women and age-matched men, but the reasons are not fully understood. Coronary endothelial function (CEF), a barometer of coronary vascular health, promises important insights into age and sex differences in atherosclerotic CVD risk, but has not been well characterized in healthy individuals because of the invasive nature of conventional CEF measurements. Recently developed magnetic resonance imaging (MRI) methods were used to quantify CEF (coronary area and flow changes in response to isometric handgrip exercise (IHE), an endothelial-dependent stressor) to test the hypothesis that healthy women have better CEF compared to men particularly at a younger age...
