BACKGROUND AND AIMS: The current study was conducted to assess the ability of CHA2DS2-VASc, CHADS2 and HATCH scores in predicting new-onset atrial fibrillation (AF) among patients with cancer. METHODS: Patients with newly diagnosed cancer between 1 January, 2000 and 31 December, 2011, from the Registry for Catastrophic Illness Patient Database, were defined as the study cohort. CHA2DS2-VASc, CHADS2 and HATCH scores were used for new-onset AF prediction in these study patients, and the predictive accuracy of the scores was assessed by the receiver operating characteristics (ROC) curve...

BACKGROUND AND AIMS: Altered metabolism is an important regulator of macrophage (MΦ) phenotype, which contributes to inflammatory diseases such as atherosclerosis. Broadly, pro-inflammatory, classically-activated MΦs (CAM) are glycolytic while alternatively-activated MΦs (AAM) oxidize fatty acids, although overlap exists. We previously demonstrated that MΦ fatty acid transport protein 1 (FATP1, Slc27a1) was necessary to maintain the oxidative and anti-inflammatory AAM phenotype in vivo in a model of diet-induced obesity...

BACKGROUND AND AIMS: Genetic and environmental factors are important components of the development of atherosclerosis. Long non-coding RNA (lncRNAs) have emerged as regulators of multiple pathophysiological pathways in the cardiovascular system. Here, we investigated potential associations between lncRNAs and atherosclerosis. METHODS: Tissue samples from atherosclerotic coronary artery plaques and non-atherosclerotic internal mammary artery were obtained from 20 patients during coronary artery bypass surgery...

BACKGROUND AND AIMS: The effects of low dose prednisolone on circulating markers of endothelial function, the arginine metabolites asymmetric dimethyl arginine (ADMA), mono methyl arginine (MMA), and homoarginine, are uncertain. We assessed whether patients with rheumatoid arthritis have perturbations in arginine metabolite concentrations that are reversed by low dose prednisolone. METHODS: Eighteen rheumatoid arthritis patients who had not taken prednisolone for >6 months (non-glucocorticoid (GC) users), 18 rheumatoid arthritis patients taking continuous oral prednisolone (6...

BACKGROUND AND AIMS: Lipopolysaccharide (LPS) is a main component of the Gram-negative bacterial cell wall and is associated with a greater risk of atherosclerosis development in periodontal disease. LPS has been reported to increase both CD36 and CD204 expression and enhance the uptake of modified low-density lipoprotein (LDL). However, the signaling pathways by which LPS enhances these expression levels and function have not been fully elucidated, although the clarification of these signaling pathways is important for identifying therapeutic targets for atherosclerosis...

BACKGROUND AND AIMS: We aimed at investigating the effect of celecoxib (COX-2 selective inhibitor) and diclofenac (non-selective COX inhibitor) on endothelial function, and at identifying the underlying mechanisms in adjuvant-induced arthritis (AIA). METHODS: At the first signs of AIA, diclofenac (5 mg/kg twice a day, i.p), celecoxib (3 mg/kg/day, i.p) or saline (Vehicle) was administered for 3 weeks. Endothelial function was studied in aortic rings relaxed with acetylcholine (Ach) with or without inhibitors of NOS, arginase, EDHF and superoxide anions (O2(-°)) production...

BACKGROUND AND AIMS: Recent evidence suggests that endoplasmic reticulum (ER) stress signaling through glycogen synthase kinase (GSK)-3α/β is involved in the activation of pro-atherosclerotic processes. In this study, we examined the effects of small molecules that interfere with ER stress-GSK3α/β signaling on the progression and regression of atherosclerosis in a mouse model. METHODS: To examine atherosclerotic progression, low-density lipoprotein receptor deficient (Ldlr(-/-)) mice were placed on a high-fat diet (HFD) and treated with the chemical chaperone, 4-phenylbutyrate (4PBA, 3...

BACKGROUND AND AIMS: Distribution of monocyte subsets has been shown to predict cardiovascular outcomes. However, monocytes form a continuum and categorization into discrete subsets may be an oversimplification. We herein aimed at establishing whether distribution of monocytes based on CD14 and CD16 fluorescence intensity provides incremental and complementary information on cardiovascular outcomes beyond enumeration of traditional subsets. METHODS: A cohort of 227 patients at high cardiovascular risk was characterized at baseline and followed for a median of 4 years...

BACKGROUND AND AIMS: Increased proinsulin relative to insulin levels have been associated with subclinical atherosclerosis (measured by carotid intima-media thickness (cIMT)) and are predictive of future cardiovascular disease (CVD), independently of established risk factors. The mechanisms linking proinsulin to atherosclerosis and CVD are unclear. A genome-wide meta-analysis has identified nine loci associated with circulating proinsulin levels. Using proinsulin-associated SNPs, we set out to use a Mendelian randomisation approach to test the hypothesis that proinsulin plays a causal role in subclinical vascular remodelling...

BACKGROUND AND AIMS: Dronedarone reduced the rate of stroke and transient ischemic attack in patients with paroxysmal atrial fibrillation (AF) in the ATHENA trial. This cannot be explained by its antiarrhythmic effect alone and may involve alternative mechanisms. This study aimed to investigate any direct effect of dronedarone on blood thrombogenicity, independent of its antiarrhythmic effects. METHODS: Blood samples from patients with cardiovascular disease (n = 30) taking no anticoagulant or antiplatelet medication except aspirin were incubated with dronedarone's active metabolite (SR35021A) at 66 ng/ml (am-L) and 119 ng/ml (am-H), i...

BACKGROUND AND AIMS: Asymmetric dimethylarginine (ADMA) is an inhibitor of nitric oxide and an independent risk factor for cardiovascular disease. We examined the effect of statin on ADMA in HIV + patients on stable ART, and whether such an effect contributes to the favorable changes on carotid intima media thickness. METHODS: This is a secondary analysis of SATURN-HIV, in which HIV + adults on stable ART with HIV-1 RNA< 1000 copies/mL and LDL-cholesterol <130 mg/dL were randomized to 10 mg daily rosuvastatin or placebo...

BACKGROUND AND AIMS: Heart failure (HF) and atrial fibrillation/flutter (AF) are important causes of morbidity and mortality. Subjects with familial hypercholesterolemia (FH) carry a high risk of coronary artery disease (CAD) but it is not known if the risk of HF and AF is increased in FH. The present study investigated the incidence of hospitalization for HF and AF in a genetically verified FH cohort, age 25 years and older, compared to the general population. METHODS: Incidence rates of hospitalization for HF and AF were estimated from national registry data...

BACKGROUND AND AIMS: Statin is not beneficial for dialysis patients but moderate to high intensity statin is beneficial for patients after acute myocardial infarction (MI). The aim of this study was to evaluate the effect of moderate to high intensity statin on mortality, cardiovascular outcomes in dialysis patients after acute MI. METHODS: Data on dialysis patients were retrieved from the National Health Insurance Research Database in Taiwan. Dialysis patients admitted for MI were selected and divided into two groups according to statin prescription or not after MI...

BACKGROUND AND AIMS: Adiposity phenotypes can be detected by anthropometric indexes associated with type-2 diabetes mellitus (T2DM). Besides body mass index (BMI) and waist circumference (WC), new indices seem to be able to identify T2DM. This study aimed to evaluate independent associations of T2DM with lipid accumulation product (LAP index), neck circumference (NC) and body adiposity index (BAI) in patients with hypertension. METHODS: A cross-sectional study was carried out among 430 patients with hypertension...

BACKGROUND AND AIMS: Previously, we showed that patients undergoing carotid endarterectomy have an increased risk for major atherosclerotic events in the presence of moderate or poor kidney function. Acceleration of vascular inflammatory responses is considered to be causally involved in progression of atherogenesis and poor outcome in chronic kidney disease patients. The association between kidney function and plaque composition has not been thoroughly investigated yet. The aim of this study was to investigate the association between kidney function and atherosclerotic plaque composition in patients undergoing carotid endarterectomy...

REVIEW
Natalie Ly Ngu, Mark McEvoy
BACKGROUND AND AIMS: Despite worldwide reductions in active smoking, non-smokers continue to be exposed to environmental tobacco smoke, especially at home or workplace. There is a well-recognised association between active smoking and peripheral arterial disease, however, a relationship to environmental tobacco smoke exposure is less substantiated. The aims of this paper are to review the literature regarding the association between environmental tobacco smoke and peripheral arterial disease and identify the public health implications of the findings...

BACKGROUND AND AIMS: Reduced kidney function is a risk factor for lower-extremity peripheral artery disease (PAD). However, the associations of novel filtration markers with PAD are yet to be quantified. Moreover, little is known on whether bone-mineral metabolism (BMM) markers are related to incident PAD beyond kidney function. METHODS: Using data from 12,472 participants at baseline (1990-1992) of the Atherosclerosis Risk in Communities (ARIC) study, we comprehensively quantified the associations of kidney related markers with incident PAD (defined as hospitalizations with diagnosis of lower-extremity atherosclerosis, revascularization, or amputation)...
