BACKGROUND AND OBJECTIVES The treadmill exercise test (TMT) is used as a first-line test for diagnosing coronary artery disease (CAD). However, the findings of a TMT can be inconclusive, such as incomplete or equivocal results. Aortic valve sclerosis (AVS) is known to be a good predictor of CAD. We determined the usefulness of assessing AVS on 2-dimensional(More)
BACKGROUND AND OBJECTIVES Little evidence is available on the optimal antithrombotic therapy following percutaneous coronary intervention (PCI) in patients with atrial fibrillation (AF). We investigated the outcomes of antithrombotic treatment strategies in AF patients who underwent PCI. SUBJECTS AND METHODS Three hundred sixty-two patients (68.0% men,(More)
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)
Posteroseptal accessory pathways are often associated with coronary sinus diverticula. These diverticula contain myocardial coats which serve as a bypass tract. We report a 54-year-old woman who underwent radiofrequency (RF) catheter ablation for Wolff-Parkinson-White (WPW) syndrome. The surface electrocardiography (ECG) demonstrated pre-excitation,(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)
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)
The aim of this study was to investigate the anatomic relationship around the left atrium (LA) and to provide clinical information to help avoid the risk of an atrio-esophageal fistula during atrial fibrillation (AF) ablation. The multidetector spiral computed tomography images of 77 male patients (mean age, 54 ± 9 years) with drug-refractory AF and 37 male(More)
OBJECTIVE Previous pathologic and roentgenographic studies have suggested a relation between aortic plaque and coronary artery disease but have lacked clinical utility. The study was undertaken to elucidate whether atherosclerotic aortic plaque detected by transesophageal echocardiography can be a clinically useful marker for significant obstructive(More)
