Abstract
Abstract
Atrial fibrillation is the most frequent arrhythmia in adults, becoming more frequent with age. Recent clinical studies demonstrated that epicardial fat is linked with atrial fibrillation induction and recurrence. The arrhythmogenic mechanism consists in the fact that the epicardial adipose tissue is metabolically active, inducing local inflammation and enhancing the oxidative stress, which lead to atrial fibrillation as well as atherosclerosis. Having metabolic activity and secreting various anti- and pro-inflammatory biomarkers, the fat surrounding the heart has been linked to the complex process of coronary plaque vulnerabilization. This clinical update aims to summarize the role of epicardial adipose tissue in the pathogenesis, persistence, and severity of atrial fibrillation.

Abstract
The epidemic of atrial fibrillation (AF) is increasingly recognised as a growing health problem worldwide. Although epidemiological studies on AF in the Asia-Pacific region are scarce, given the increasing age and size of populations in this region, the burden of AF is expected to be far greater than in North America and Europe. This is not only due to the growing, ageing population but also an increased incidence of risk factors for AF, such as hypertension, obesity, metabolic syndrome and diabetes, in the Asia-Pacific region. While further, high quality data on such aspects as risk factors, racial disparities and clinical implications is urgently required, there is an immediate need for increased focus on appropriate stroke prophylaxis and risk factor management to minimise the clinical complications and societal burden of AF.

Abstract
OBJECTIVE Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine secreted by macrophages. This study is performed to investigate whether serum MIF is correlated with atrial fibrillation (AF). METHODS Totally, 186 AF patients and 103 healthy controls were enrolled in this study. AF patients were then divided into paroxysmal AF, persistent AF, and permanent AF subgroups. RESULTS There were higher serum MIF concentrations in AF patients than in healthy subjects. Logistic regression analysis demonstrated that serum MIF was associated with AF. Permanent AF patients exhibited higher serum MIF concentrations than persistent and paroxysmal AF subgroups. Elevated serum MIF concentrations were found in persistent AF patients compared with paroxysmal AF patients. Moreover, serum MIF concentrations were associated with left atrial diameter after Spearman correlation analysis.
