Background Suppression of lipid signal is a basic requirement in coronary magnetic resonance angiography (CMRA) because coronary arteries are embedded in epicardial fat and signal from fat can decrease coronary vessel conspicuity. Most CMRA scans are currently performed with fat suppression techniques such as Spectral Presaturation with Inversion Recovery (SPIR). However, methods based on spect...
BACKGROUND The relationship between arrhythmogenic right ventricular cardiomyopathy (ARVC) and pure fat replacement of the right ventricle is unclear. METHODS AND RESULTS Myocardial thickness, epicardial fat thickness, percent fibrosis, and intramyocardial fat infiltration were measured in 16 sections each from 25 hearts with typical (fibrofatty) ARVC, 7 hearts with fat replacement of the rig...

Mahabadi AA, Berg MH, Lehmann N, Kälsch H, Bauer M, Kara K, et al. Association of epicardial fat with cardiovascular risk factors and incident myocardial infarction in the general population: the Heinz Nixdorf Recal...
A 62-year-old man with no history of cardiac disease was referred because of exertional dyspnea. His body mass index was elevated at 29 kg/m, and a large cutaneous lipoma was present on his abdominal wall. Transthoracic echocardiography was performed and initially reported to demonstrate a moderate-sized global pericardial effusion (Figure 1 and Movies 1 and 2). Consideration was given to peric...
Epicardial adipose tissue (EAT) has been found to be an important reliable marker for future coronary events. Deposition of the EAT in young individuals is not well known. We studied EAT in 25 young overweight or obese individuals. In spite of the high visceral fat and total body fat, EAT thickness was not found to be high in the participants of our study.
Background and Aim: Due to the prevalence and socio-economic consequences of obesity in mortality, cardiovascular (CAD) and nonalcoholic fatty liver disease the effectiveness of aerobic exercise on epicardial adipose tissue (EAT), insulin resistance (IR) and some liver enzymes of high-fat diet-induced obesity male wistar rats was investigated. Methods: Thirty-two male Wistar rats with an averag...
Chronic obstructive pulmonary disease (COPD) is a type of lung disease characterized by progressive development of obstructed airflow and an increased chronic inflammatory response in the airways1. COPD is a major cause of morbidity and mortality worldwide2. The BODE index, is an important prognostic predictor of COPD, and is a multidimensional scoring system, combining information about variou...
Oxidized cholesterols (oxycholesterols) in food have been recognized as strong atherogenic components, but their tissue distributions and roles in cardiovascular diseases remain unclear. To investigate whether accumulation of oxycholesterols is linked to cardiac morphology and function, and whether reduction of oxycholesterols can improve cardiac performance, domestic male swine were randomized...
BACKGROUND Atrial electrical remodeling (AER) is the underlying mechanism of atrial fibrillation (AF). The present study investigated the impact of epicardial fat pad (FP) ablation on acute AER (AAER) and inducibility of AF. METHODS AND RESULTS AAER was performed in 28 mongrel dogs through 4-h rapid atrial pacing (RAP). Before RAP, 14 dogs (ablation group) underwent FP ablation, and the other...
BACKGROUND The purpose of this study was to test whether radiofrequency catheter ablation (RFCA) of 3 epicardial fat pads that resulted in efferent vagal denervation of the atria and sinus and atrioventricular nodes also denervated the ventricles. METHODS AND RESULTS Vagal innervation of the ventricles was determined by measuring prolongation of ventricular effective refractory period induced...
