INTRODUCTION As epicardial adipose tissue (EAT) is a metabolically active visceral fat, potential interaction between EAT and myocardium is strongly suggested. The aims of this study were to determine whether the amount and regional distribution of EAT are related to the chronicity of atrial fibrillation (AF) and left atrial (LA) remodeling. METHODS AND(More)
OBJECTIVE The effect of non-alcoholic fatty liver disease (NAFLD) on cardiovascular system remains controversial. We investigated the independent contribution of NAFLD to cardiovascular structure and function in the general population. METHODS A total of 1886 participants without known cardiovascular disease were enrolled from the Korean Genome(More)
A single coronary artery (SCA) is a rare congenital anomaly of the coronary circulation, which is often associated with other congenital anomalies. The reported incidence of a SCA ranges from 0.6 to 1.3% of the population undergoing coronary angiography. The absence of the right coronary artery (RCA) with the origin of the RCA arising from the distal(More)
BACKGROUND Left lateral mitral isthmus (LLMI) ablation achieves a low percentage of bidirectional conduction block in atrial fibrillation (AF) ablation. OBJECTIVE The purpose of this study was to investigate whether linear ablation through the lowest voltage area on the left atrial anterior wall (LAAW) can lead to better clinical outcomes compared to LLMI(More)
BACKGROUND We questioned whether the empirical four pulmonary vein (PV) isolation (EmPVI) was necessary in patients with paroxysmal atrial fibrillation (PAF) triggered from clearly and reproducibly defined arrhythmogenic PVs. METHODS We compared the selective or ipsilateral isolation of the PVs triggering AF (SePVI: n = 42) and EmPVI (n = 35) in 77(More)
OBJECTIVE The relationship betweens the healthy obese phenotype and the risk of cardiovascular events remains unclear. We prospectively investigated the association between the obesity phenotype and the incidence of hypertension. METHODS We studied 2352 participants, aged 40-69 years at baseline, with normal blood pressure (BP) from the Ansan cohort and(More)
BACKGROUND atrial tachycardia (AT) commonly recurs within 3 months after radiofrequency catheter ablation for atrial fibrillation (AF). However, it remains unclear whether early recurrence of atrial tachycardia (ERAT) predicts late recurrence of AF or AT. METHODS of 352 consecutive patients who underwent circumferential pulmonary vein isolation with or(More)
Frequent premature ventricular complexes (PVCs) from the right ventricular outflow tract (RVOT) have recently been reported to be a cause of dilated cardiomyopathy. We studied the clinical impact of the elimination of PVCs from RVOT and non-RVOT.Thirty-six patients with symptomatic PVCs that were treated with radiofrequency catheter ablation (RFCA) were(More)
To examine the prevalence of the Type D construct using the Korean version of the Type D Personality-14 (DS14) on the Korean youth population and to identify relationships between the Type D construct and other mental health measures. Adolescent participants aged 13–18 years were recruited from 12 schools (7 middle schools and 5 high schools) in Ansan city,(More)
