OBJECTIVE We evaluated prevalence and severity of angiographic coronary artery disease (CAD) according to groups by metabolically obese (MO) and/or weight status. MATERIAL/METHODS Normal weight was defined as body mass index (BMI, kg/m²)<25 and obesity was defined as BMI≥25. The MO was determined using the National Cholesterol Education Program-Adult(More)
Dyssynchrony is common in asymptomatic patients with hypertension. We sought to investigate the impact of antihypertensive treatment on dyssynchrony in patients with hypertension. A total of sixty patients who had uncomplicated hypertension that had never been treated (treatment-naïve hypertensive patients) underwent echocardiographic evaluations of left(More)
OBJECTIVE Prevalence of left ventricular systolic dyssynchrony (LVSD) is over 40% in treatment-naive patients with hypertension and it improves after chronic antihypertensive treatment. These findings might support the hypothesis that blood pressure (BP), BP-derived parameters, central BP, or arterial stiffness would contribute to LVSD. Therefore, we aimed(More)
Smoking is associated with increased plasma homocysteine levels, and both are associated with an increased risk of cardiovascular disease. However, little information is available on the effects of passive smoking on the level of homocysteine in nonsmokers. We analyzed the data of self-reported never-smokers (aged > or = 20 years, n = 3,232), who were from(More)
Spontaneous medialstinal emphysema (pneumomediastinum) and pneumopericardium may be defined as the presence of free air or gas in the mediastinal structures and in the pericardial sac without an apparent precipitating cause. It most frequently occurs in young healthy adults without serious underlying pulmonary disease. Although pneumomediastinum and(More)
Dysphagia aortica is difficulty in swallowing caused by extrinsic compression of the esophagus due to an ectatic, tortuous, or aneurysmatic atherosclerotic thoracic aorta. This condition is very uncommon, and it is usually associated with old age, women with short stature, hypertension, and kyphosis. We report herein a case involving a patient with(More)
BACKGROUND The objective of this study was to determine the prevalence of electrocardiographic (ECG) findings suggestive of sudden cardiac death risk in apparently healthy young Korean men. METHODS We administered questionnaires that elicited personal and family histories and performed ECGs on 10,867 male subjects (mean age, 20.9 years). The subjects with(More)
BACKGROUND Left anterior line (LAL) has been used as a substitute for mitral isthmus line for catheter ablation of chronic atrial fibrillation (AF). However, it results in left anterolateral conduction delay and might affect left atrial (LA) contractility. We aimed to investigate whether LAL decreases LA appendage function. METHODS This study included 46(More)
BACKGROUND Little is known about the relationship between resting electrocardiogram (ECG) parameters and the incidence of coronary heart disease (CHD). We sought to establish the association between ECG parameters and estimated 10-year risk for CHD. METHODS We applied the risk prediction algorithm used by the National Cholesterol Education Program Adult(More)
