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)
BACKGROUND The incidence and clinical prognosis of diffuse and multivessel coronary spasm has not been reported. METHODS Patients with suspected vasospastic angina were prospectively enrolled. Left and right coronary angiogram was performed simultaneously after intravenous ergonovine injection. Spasm (>70% luminal narrowing) was sub-classified as diffuse(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)
There are limited data on the optimal antithrombotic therapy for patients with atrial fibrillation (AF) who undergoing coronary stenting. We reviewed 203 patients (62.6 % men, mean age 68.3 ± 10.1 years) between 2003 and 2012, and recorded clinical and demographic characteristics of the patients. Clinical follow-up included major adverse cardiac and(More)
Congenital absence of left circumflex coronary artery (LCX) is a very rare congenital anomaly of the coronary circulation, and few cases have been reported in the literature. We report a case of a 48-year-old male who had congenital absence of LCX presented with vasospastic angina. Routine coronary angiography showed congenital absence of the LCX, typical(More)
The longstanding compression-relaxation effects of myocardial bridging may produce endothelial dysfunction by direct stress on the endothelium. We tested the hypothesis that myocardial bridging induces endothelial dysfunction and subsequently increases the risk of coronary spasm and investigated the symptomatic response to medication in patients with(More)
BACKGROUND Aortic stiffness is an independent risk factor for cardiovascular (CV) events and mortality. However, there are few studies about the predictive role of aortic stiffness. We investigated the association between aortic pulse-wave velocity (aPWV), using direct intra-arterial measurement and future CV events, in patients with chest pain. METHODS(More)
BACKGROUND This study is aimed to assess the initiation and maintenance mechanisms of atrial fibrillation (AF) and their relationships with the anatomical structures of the left atrium (LA) and pulmonary veins (PVs). METHODS Thirty-seven patients (pts; 33 men, mean age 50+/-12, range 25-68 years) with paroxysmal AF (n=29) and persistent AF (n=8) who(More)
