BACKGROUND AND AIMS: Few studies have investigated the association of different measures of adiposity with carotid plaque. We aimed to investigate and compare the associations of four measures of adiposity: body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR) with the presence of carotid plaque and total plaque area (TPA) in the right carotid artery. METHODS: We included 4906 individuals aged 31-88 years who participated in a population-based study with ultrasonography of the right carotid artery...

BACKGROUND AND AIMS: Dyslipidemia in HIV-infected patients is unique and pathophysiologically associated with host factors, HIV itself and the use of antiretroviral therapy (ART). The use of nuclear magnetic resonance spectroscopy (NMR) provides additional data to conventional lipid measurements concerning the number of lipoprotein subclasses and particle sizes. METHODS: To investigate the ability of lipoprotein profile, we used a circulating metabolomic approach in a cohort of 103 ART-naive HIV-infected patients, who were initiating non-nucleoside analogue transcriptase inhibitor (NNRTI)-based ART, and we subsequently followed up these patients for 36 months...

BACKGROUND AND AIMS: Left-sided valvular calcification is associated with cardiovascular disease (CVD) morbidity and mortality. Resting heart rate (RHR) may influence valvular calcium progression through shear stress. Whether RHR, an established CVD risk factor, is associated with valvular calcium progression is unknown. We assessed whether RHR predicts incidence and progression of mitral annular calcium (MAC) and aortic valve calcium (AVC) in a community-based cohort free of CVD at baseline...

BACKGROUND AND AIMS: Obesity and physical inactivity are both associated with low-grade inflammation and endothelial dysfunction. Bariatric surgery improves markers of inflammation and endothelial function, but it is unknown if physical training after bariatric surgery can improve these markers even further. Therefore, we aimed to investigate the effects of Roux-en-Y gastric bypass (RYGB) followed by physical training on markers of low-grade inflammation and endothelial function. METHODS: Sixty patients approved for RYGB underwent examinations pre-surgery, 6, 12, and 24 months post-surgery...

BACKGROUND AND AIMS: Wnt signaling is involved in atherosclerotic plaque formation directly and indirectly by modulating cardiovascular risk factors. We investigated whether circulating concentrations of Wnt inhibitors are associated with cardiovascular events in subjects with intermediate cardiovascular risk. METHODS: 904 non-diabetic subjects participating in the SAPHIR study were assessed. In the SAPHIR study, middle-aged women without overt atherosclerotic disease at study entry were followed up for 10 years...

BACKGROUND AND AIMS: Aortic valve stenosis (AS) is the most common valvular heart disease and can be life-threatening. The pathogenesis of aortic valve calcification remains largely unknown, primarily due to the lack of an adequate animal model. The high-cholesterol diet-induced AS model in rabbits is one of the established models, but it has the significant limitation of liver dysfunction leading to low survival rates. We hypothesized that a myocardial infarction-prone Watanabe heritable hyperlipidemic (WHHLMI) rabbit, an animal model of familial hypercholesterolemia and atherosclerosis, is a useful animal model of AS...

BACKGROUND AND AIMS: Pathologic intimal thickening (PIT) is an important stage of atherosclerosis that leads to atheroma. The present study aimed to clarify the pathogenesis of PIT in humans. METHODS: Coronary arteries were obtained from 43 autopsy subjects aged 15-49 years. Non-atherosclerotic intima and atherosclerotic intimal lesions were classified into four groups, i.e. diffuse intimal thickening, fatty infiltration, fatty streak, and PIT, and the number and density of macrophages and smooth muscle cells (SMCs) were determined...

BACKGROUND AND AIMS: Nicotinic acid administration causes plasma non-esterified fatty acid (NEFA) reduction and plasma lipid changes, including reduced triglyceride levels. GPR109A, which is expressed mainly in adipose tissue and has anti-lipolytic activity, was reported to be a molecular target for nicotinic acid. However, recent clinical reports have shown that most GPR109A agonists failed to induce clinically meaningful plasma lipid changes. In addition, a recent study has shown that the TG lowering effect of nicotinic acid was not diminished in Gpr109a deficient mice, which is different from the original finding...

BACKGROUND AND AIMS: Methionine (Met) is an essential amino acid involved in methylation reactions and lipid metabolism. A Met-deficient diet may cause hepatic lipid accumulation, which is considered an independent risk factor for atherosclerosis. However, the prospective relationship between circulating Met and incident acute myocardial infarction (AMI) is unknown. METHODS: We studied the associations of plasma Met and incident AMI in 4156 patients (77% men; median age 62 years) with stable angina pectoris, among whom the majority received lipid lowering therapy with statins...

BACKGROUND AND AIMS: Hepatocyte growth factor (HGF) has previously been associated with risk of stroke, coronary heart disease, and atherosclerosis. We hypothesized that higher circulating HGF is associated with greater progression of measures of atherosclerosis: coronary artery calcium (CAC) and carotid plaque. METHODS: Participants aged 45-84 years from the prospective cohort study Multi-Ethnic Study of Atherosclerosis had HGF measured at baseline (between 2000 and 2002) and were followed for progression of atherosclerosis for up to 12 years...

BACKGROUND AND AIMS: Calcific aortic valve disease (CAVD) is the most common valve disease. Although micronutrients are known to contribute to cardiovascular disease, the relationship with CAVD remains poorly evaluated. We examined the association of serum levels of magnesium, phosphorus, and calcium with prevalence, incidence, and progression of aortic valve calcification (AVC). METHODS: We conducted a prospective study in a population-based sample of Japanese men aged 40-79 years without known cardiovascular disease and chronic kidney disease at baseline, and quantified AVC from serial computed tomographic images with the Agatston method...

BACKGROUND AND AIMS: Peripheral artery disease (PAD) is associated with poor mobility and fatigue, but the relationship between preclinical ankle-brachial index (ABI) and early markers of fatigue and functional decline has not been defined. METHODS: 570 adults, 50 and older, from the Baltimore Longitudinal Study of Aging (N = 570), with normal values of ABI (1-1.39), were classified into ABI tertiles. Perceived fatigability was assessed after a 5-min, treadmill walk (1...

Coronary heart disease (CHD) is one of the leading disorders with the highest mortality rate. Percutaneous angioplasty and stent implantation are the currently available standard methods for the treatment of obstructive coronary artery disease. However, the stent being an exogenous substance causes several complications by promoting the proliferation of vascular smooth muscle cells, immune responses and neointima formation after implantation, leading to post-stent restenosis (ISR) and late thrombosis. The prevention of these adverse vascular events is important to achieve long-term proper functioning of the heart after stent implantation...

BACKGROUND AND AIMS: The possible contribution of iron to cardiovascular complications of type 2 diabetes (T2D) has been scarcely investigated. We aimed to study whether serum ferritin is linked to prevalent/incident cardiovascular disease (CVD) in T2D. METHODS: The prevalence of coronary heart disease (CHD), cerebrovascular disease (CEVD) and CVD was evaluated in the SIDIAP study (n = 38,617) and prevalence and 7-year incidence were analysed in the Edinburgh Type 2 Diabetes Study (ET2DS) (n = 821)...
