OBJECTIVE: Epicardial fat tissue reflects visceral adiposity and inflammation, and neutrophil to lymphocyte ratio (NLR) has been investigated as important inflammatory marker in cardiovascular disease. We aimed to investigate the relationship of echocardiographic epicardial fat thickness (EFT) and NLR with diurnal blood pressure (BP) changes in patients with recently diagnosed essential hypertension. DESIGN AND METHOD: A total of 647 hypertensive patients underwent echocardiography and 24-hours ambulatory BP monitoring...

BACKGROUND: The cause of premature cardiovascular disease (CVD) in inflammatory rheumatic diseases (IRDs) has not been fully elucidated. As inflammation may play a role, we wanted to compare the occurrence and extent of inflammatory cell infiltrates (ICIs), small vessel vasculitis, and the amount of adipose tissue and collagen in cardiac biopsies taken from patients with coronary artery disease with and without IRDs. METHODS: From among the Feiring Heart Biopsy Study subjects, we selected patients undergoing coronary artery bypass grafting from whom paraffin-embedded, formalin-fixed specimens from the right atrium were available...

BACKGROUND: Inflammatory activity originating from the epicardial adipose tissue (EAT) may have a role in coronary artery disease (CAD) pathogenesis. The relationship between macrophage infiltration, polarization in the EAT, and netrin-1 gene expression was investigated. METHODS: Macrophage infiltration and polarization were examined by immunohistochemical methods and expression levels of netrin-1, Unc5b, and cytokines related with M1-macrophage subtype (IL-12 and IL-18) were determined by quantitative polymerase chain reaction in subcutaneous and epicardial adipose tissue obtained from patients undergoing coronary artery bypass grafting and non-coronary cardiac surgery...

BACKGROUND: Although epicardial adipose tissue (EAT) volume is associated with increased incidence of coronary artery disease (CAD), its role in myocardial systolic dysfunction is unclear. The present study aimed to identify independent determinants of EAT volume in patients without obstructive CAD, and to evaluate the association between EAT volume (vs other measures of obesity) and myocardial systolic strain analysis. METHODS: We prospectively recruited 130 patients without obstructive CAD on contrast-enhanced cardiac computed tomography imaging and normal left ventricular ejection fraction on 3-dimensional (3D) echocardiography...

BACKGROUND: The aim of this study is to evaluate the effect of epicardial adipose tissue (EAT) thickness on left ventricular diastolic functions in patients with normal coronary arteries (NCA) proven by angiography. METHODS: We selected study patients who were referred to coronary angiography due to typical chest pain or atypical chest pain with a positive pre-test result for coronary artery disease. After coronary angiography, 85 patients had significant coronary lesion (≥50% stenosis) served as coronary artery disease (CAD) group, 82 patients had non-significant coronary lesion (<50% stenosis) and/or a coronary plaque served as non-significant CAD group and 83 patients had normal coronary arteries served as normal coronary artery (NCA) group...

Obesity, the major cause of the current global epidemic of type 2 diabetes (T2D), induces insulin resistance in peripheral insulin target tissues. Several mechanisms have been identified related to cross-talk between adipose tissue, skeletal muscle and liver. These mechanisms involve both increased free fatty acid release and altered secretion of adipokines from adipose tissue. A major determinant of metabolic health is the ability of subcutaneous adipose tissue (SAT) to store excess fat rather than allowing it to accumulate in ectopic depots including liver (i...

Studies in rodents and newborn humans demonstrate the influence of brown adipose tissue (BAT) in temperature control and energy balance and a critical role in the regulation of body weight. Here, we obtained samples of epicardial adipose tissue (EAT) from neonates, infants, and children in order to evaluate changes in their transcriptional landscape by applying a systems biology approach. Surprisingly, these analyses revealed that the transition to infancy is a critical stage for changes in the morphology of EAT and is reflected in unique gene expression patterns of a substantial proportion of thermogenic gene transcripts (~10%)...

OBJECTIVE: Atherosclerotic coronary artery disease is a leading cause of death, worldwide. Diagonal earlobe crease (DELC) has been suggested as a simple, noninvasive marker of cardiovascular disease. Although epicardial adipose tissue (EAT) thickness and carotid intima media thickness (CIMT) are closely related to atherosclerosis, the relation between EAT, CIMT, and DELC had yet to be studied. The present objective was to analyze this association. METHODS: Subjects were apparently healthy individuals referred to the cardiology outpatient clinic...

Recent findings indicate a strong correlation between the risk of future heart disease and the volume of adipose tissue inside of the pericardium. So far, large-scale studies have been hindered by the fact that manual delineation of the pericardium is extremely time-consuming and that existing methods for automatic delineation lack accuracy. An efficient and fully automatic approach to pericardium segmentation and epicardial fat volume (EFV) estimation is presented, based on a variant of multi-atlas segmentation for spatial initialization and a random forest classifier for accurate pericardium detection...

BACKGROUND AND AIMS: Epicardial adipose tissue (EAT) has been proposed as a cardiometabolic and hepatic fibrosis risk factor in patients with non alcoholic fatty liver disease (NAFLD). Aim of this study was to evaluate the role of EAT in NAFLD by analyzing 1) the association between EAT, the other metabolic parameters and the severity of steatosis 2) the relationship between cardiovascular (cIMT, cplaques, E/A), liver (presence of NASH and significant fibrosis) damage and metabolic risk factors including EAT 3) the relationship between EAT and genetic factors strongly influencing liver steatosis...

Obesity is characterized by an excessive fat accumulation in adipose tissues leading to weight gain and is increasing in prevalence and is strongly associated with metabolic and cardiovascular disorders. The renin-angiotensin system (RAS) has emerged as a key pathogenic mechanism for these disorders; activated RAS and angiotensin (Ang) II production results in worsening of cardiovascular diseases and angiotensin converting enzyme 2 (ACE2) negatively regulates RAS by metabolizing Ang II into Ang 1-7. ACE2 is expressed in the adipocytes and its expression is upregulated in response to high fat diet induced obesity in mice...

BACKGROUND: Metabolic syndrome is a combination of multiple cardiovascular (CV) risk factors including insulin resistance (IR). Carotid, femoral intima media thickness (IMT), and epicardial fat thickness (EFT) are considered as novel cardiometabolic risk factors. We aimed to test the hypothesis that carotid, femoral IMT, and EFT are increased in patients with IR. METHODS: We enrolled consecutively and prospectively 113 patients with IR. Then we collected data from an age- and sex-matched control group of 112 individuals without IR...

Background. Epicardial adipose tissue (EAT) is identified as an atypical fat depot surrounding the heart with a putative role in the involvement of metabolic disorders, including obesity, type-2 diabetes mellitus, and atherosclerosis. We profiled miRNAs in EAT of metabolic patients with coronary artery disease (CAD) and type-2 diabetes mellitus (T2DM) versus metabolically healthy patients by microarray. Compared to metabolically healthy patients, we identified forty-two miRNAs that are differentially expressed in patients with CAD and T2DM from Xinjiang, China...

OBJECTIVE: Carotid intima-media thickness (CIMT) is reliable marker of subclinical atherosclerosis and cardiovascular events. Until today, there was no study that investigated whether epicardial adipose tissue (EAT), which is a surrogate for lipid depot in a special visceral tissue or circulating lipids, is more important for CIMT and atherosclerotic plaque. METHODS: Our study, having cross-sectional and prospective observational design, included 252 patients who were admitted to our outpatient clinic...

BACKGROUND: Epicardial adipose tissue (EAdT) is metabolically active and likely contributes to atrial fibrillation (AF) through the release of inflammatory cytokines into the myocardium or through its rich innervation with ganglionated plexi at the pulmonary vein ostia. The electrophysiologic mechanisms underlying the association between EAdT and AF remain unclear. OBJECTIVE: The purpose of this study was to investigate the association of EAdT with adjacent myocardial substrate...

BACKGROUND: Although recent studies indicate that epicardial adipose tissue expresses brown fat-like genes, such as PGC1α, UCP1 and PRDM16, the association of these genes with type 2 diabetes mellitus (DM2) in coronary artery disease (CAD) remains unknown. METHODS: PGC1α, UCP1, and PRDM16 mRNAs expression levels were measured by real-time PCR in epicardial and thoracic subcutaneous adipose tissue from 44 CAD patients (22 with DM2 [CAD-DM2] and 22 without DM2 [CAD-NDM2]) and 23 non-CAD patients (NCAD)...
