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)
OBJECTIVES This study was designed to investigate whether endothelial dysfunction is related to drug-eluting stent (DES) implantation at 6 months after stenting. BACKGROUND Current available DES could delay vessel healing and subsequently impair endothelial function. METHODS Endothelial function was estimated at 6-month follow-up in 75 patients (31 men,(More)
OBJECTIVES We undertook this study to determine whether human atrial fibrillation (AF) relates to steeply sloped action potential duration restitution (APDR) kinetics and whether the spatial nonuniformity of APDR promotes persistence of AF. BACKGROUND A steeply sloped APDR curve is known to be an important determinant of the induction of more complex(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 To describe the rationale, objectives, protocol, and preliminary results for a new prospective cohort study of cardiovascular disease (CVD) risk factors in South Korea. METHODS Study members were recruited from participants in routine health assessments at health promotion centres across South Korea. Established and emerging CVD risk factors(More)
OBJECTIVE The objectives of this study were to develop a coronary heart disease (CHD) risk model among the Korean Heart Study (KHS) population and compare it with the Framingham CHD risk score. DESIGN A prospective cohort study within a national insurance system. SETTING 18 health promotion centres nationwide between 1996 and 2001 in Korea. (More)
BACKGROUND Whether triple antiplatelet therapy is superior or similar to dual antiplatelet therapy in patients with acute ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention in the era of drug-eluting stents remains unclear. METHODS AND RESULTS A total of 4203 ST-segment elevation myocardial infarction patients(More)
INTRODUCTION Although posterior wall of left atrium (LA) is known to be arrhythmogenic focus, little is known about the effect of posterior wall isolation (PWI) in patients who undergo radiofrequency catheter ablation (RFCA) for persistent atrial fibrillation (PeAF). METHODS We randomly assigned 120 consecutive PeAF patients to additional PWI [PWI (+),(More)
Constrictive pericarditis is a rare heart disease but potentially curable with pericardiectomy. Conventional image modalities such as echocardiography, CT and MRI have been used as useful diagnostics for constrictive pericarditis. However, they have limitations in delineating accurate extent of calcified pericardium three-dimensionally (3-D) to aid the(More)
