BACKGROUND: Statins are widely used for lipid lowering in patients with coronary artery disease (CAD), but increasing evidence indicates an association between statin use and new-onset of diabetes mellitus (NODM). Epicardial adipose tissue (EAT) refers to the visceral fat surrounding the heart, which is associated with metabolic diseases. We sought to determine the association between EAT thickness and NODM in CAD patients treated with high-intensity statins. METHODS: We conducted a retrospective medical record review of CAD patients treated with high-intensity statins for at least 6 months after percutaneous coronary intervention performed between January 2009 and June 2013 at Seoul National University Bundang Hospital...

Epicardial adipose tissue is not only a specific adipose tissue depot but also an active endocrine organ producing numerous substances with an important role in the development of obesity-related heart diseases. It is located between myocardium and visceral pericardium and consists predominantly of adipocytes, immunocompetent cells, ganglia and interconnecting nerve branches. Several studies documented a positive correlation between pericardial and epicardial fat and left ventricular hypertrophy and septal thickening, leading to diastolic dysfunction, electrocardiographic abnormalities and facilitating cardiac failure...

BACKGROUND: Glycosuria produced by sodium-glucose co-transporter-2 (SGLT-2) inhibitors is associated with weight loss. SGLT-2 inhibitors reportedly might reduce the occurrence of cardiovascular events. Epicardial adipose tissue (EAT) is a pathogenic fat depot that may be associated with coronary atherosclerosis. The present study evaluated the relationship between an SGLT-2 inhibitor (dapagliflozin) and EAT volume. METHODS: In 40 diabetes mellitus patients with coronary artery disease (10 women and 30 men; mean age of all 40 patients was 67...

To conduct a systematic review and meta-analysis on the crude and adjusted associations between epicardial adipose tissue (EAT) volume determined by computed tomography (CT) and coronary artery disease (CAD). MEDLINE, Scopus, and Web of Science databases were screened for all observational studies assessing the association between EAT volume and CAD. We calculated pooled odds ratio (OR) or hazard ratio (HR) and 95% confidence intervals (CI) for the association per 10 cm3 variation of EAT by five different definitions of CAD: obstructive or significant coronary stenosis (luminal narrowing ≥50% and ≥70%, respectively), presence of coronary artery calcification (CAC), myocardial ischaemia, and major adverse cardiovascular events (MACE) using DerSimonian and Laird random-effects models...

BACKGROUND AND AIMS: Sleep-disordered breathing (SDB) is common in patients with heart failure (HF), contributes to the progression of cardiac disease, and is associated with adverse prognosis. Previous evidence indicates that epicardial adipose tissue (EAT) is independently associated with sleep apnea in obese individuals. We explored the relationship between SDB and EAT in HF patients. METHODS AND RESULTS: EAT thickness was assessed by echocardiography in 66 patients with systolic HF undergoing nocturnal cardiorespiratory monitoring...

Little necropsy information is available on donor hearts in place in recipients for varying periods. Necropsy studies were performed in 79 patients who had survived from 1 day to 17 years after orthotopic heart transplantation (OHT). At OHT, the 79 patients ranged in age from 3 to 70 years (mean 51), and at death, from 20 to 76 years (mean 54). The native hearts tended to be larger than the donor hearts in the 22 patients surviving ≤60 days and the donor hearts tended to be larger in the 57 patients surviving >60 days, suggesting that the donor hearts increased in weight with time...

Context: Myotonic dystrophies (DM) are dominantly inherited muscle disorders characterized by myotonia, muscle weakness, and wasting. The reasons for sarcopenia in DMs are uncleared and multiple factors are involved. Irisin, a positive hormone regulator of muscle growth and bone, may play a role. Objectives: To investigate (1) circulating irisin in a series of DM1 and DM2 male patients compared with healthy controls and (2) the relationships between irisin and anthropometric, metabolic and hormonal parameters...

Background -The pericardial adipose tissue (AT) contains a high density of lymphoid clusters. Is unknown whether these clusters play a role in post-myocardial infarction (MI) inflammatory responses and cardiac outcome. Methods -Lymphoid clusters were examined in epicardial AT of humans with or without coronary artery disease (CAD). Murine pericardial lymphoid clusters were visualized in mice subjected to coronary artery ligation. To study the relevance of pericardial clusters during inflammatory responses after MI, we surgically removed the pericardial AT, performed B cell depletion and GM-CSF blockade...

AIMS: Increased epicardial adipose tissue (EAT), pericardial adipose tissue (PAT), periaortic adipose tissue (PaAT), and subcutaneous adipose tissue (SAT) are mediators of metabolic risk, and are associated with the severity of coronary artery calcium (CAC). Aged garlic extract (AGE) has been shown to reduce the progression of coronary atherosclerosis. This study evaluates the effect of AGE with supplements (AGE+S) on EAT, PAT, SAT, and PaAT. METHODS: Sixty asymptomatic participants participated in a randomized trial evaluating the effect of AGE+S versus placebo on coronary atherosclerosis progression, and underwent CAC at baseline and after 12 months of treatment...

Brown fat presence and metabolic activity has been associated with lower body mass index, higher insulin sensitivity and better cardiometabolic profile in humans. We, and others, have previously reported the presence of Ucp1, a marker of brown adipocytes, in human epicardial adipose tissue (eAT). Characterization of the metabolic activity and associated physiological relevance of Ucp1 within eAT, however, is still awaited. Here, we validate the presence of Ucp1 within human eAT and its 'beige' nature. Using in-vitro analytical approaches, we further characterize its thermogenic potential and demonstrate that human eAT is capable of undergoing enhanced uncoupling respiration upon stimulation...

According to the results of a preliminary study, it was hypothesized that the effects of adiponectin (APN) on the improvement of atherosclerosis may be associated with adipocyte differentiation and peroxisome proliferator‑activated receptor γ (PPARγ). The present study simulated the inflammatory environment of epicardial adipose tissue by stimulating mature adipocytes with lipopolysaccharide (LPS); subsequently, the differentiation of 3T3‑L1 preadipocytes was observed. 3T3‑L1 preadipocytes were infected with an adenovirus containing the human adiponectin gene apM1 (Ad‑apM1) and were co‑cultured with mature adipocytes stimulated with LPS...

OBJECTIVE: Growing evidence has identified that excessive accumulation of pericardial adipose tissues (PAT) and epicardial adipose tissues (EAT) is associated with atrial fibrillation (AF) development. Moreover, beige adipocytes, present in PAT and EAT, have been proved beneficial in consumption of fatty acid and promotion of weight lose by nonshivering thermogenesis. The objective of this prospective, observational study was to reveal the potential association between beige adipocytes and AF development...

HIV-infected patients commonly experience changes in central and peripheral fat content as well as ectopic fat accumulation. However, whether hepatic and epicardial fat stores relate differentially to body composition or how these associations are modified by HIV status has not been well explored. A previously recruited sample of 124 HIV-infected patients and 58 healthy controls had undergone dual energy X-ray absorptiometry (DEXA) and computed tomography (CT) from which body composition measures, liver-spleen ratio, and epicardial fat volume were obtained...
