BACKGROUND One of the most important reasons for failure of percutaneous coronary intervention (PCI) in chronic total occlusion (CTO) is calcified plaque, which either prevents passage of guide wire or ruptures after balloon inflation. We sought to evaluate whether quantified calcium contents of CTO on multi-detector computed tomography (MDCT) correlate(More)
OBJECTIVES This study sought to determine the efficacy of high-dose atorvastatin in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). BACKGROUND Previous randomized trials have demonstrated that statin pre-treatment reduced major adverse cardiac events (MACEs) in patients with(More)
Dual antiplatelet therapy with aspirin and an oral ADP P2Y12 receptor antagonist is the standard-of-care for the prevention of ischemic events in patients with acute coronary syndrome or undergoing percutaneous coronary intervention (PCI). However, currently available ADP P2Y12 receptor antagonists have several limitations, such as interindividual response(More)
This study aimed to investigate the factors determining early left atrial (LA) reverse remodeling after mitral valve (MV) surgery. The left atrium is frequently dilated in patients with mitral stenosis (MS) or mitral regurgitation (MR). MV surgery usually results in LA volume reduction. However, the factors associated with LA reverse remodeling after MV(More)
Thromboelastography (TEG) measures the effects of antithrombotic agents by assessing global functional clotting status by evaluating the viscoelastic properties of in vitro clot formation. Recently, rapid TEG (r-TEG), which uses tissue factor in addition to standard kaolin to accelerate activation of the clotting cascade, has been proposed to obtain more(More)
Atrial fibrillation (AF) represents the most common cardiac arrhythmia and chronic oral anticoagulation (OAC) is the cornerstone therapy to prevent cerebrovascular events among those having high thromboembolic risk. However, 20-30% of patients with AF have co-existing coronary artery disease (CAD). Importantly, since the prevalence of both AF and CAD(More)
BACKGROUND Serum C-reactive protein (CRP) levels, closely associated with cardiovascular disease (CVD) risk are influenced by CRP or interleukin-6 (IL-6) single nucleotide polymorphism (SNPs). However, it is still controversial. Therefore, we investigated the association of IL-6/CRP SNPs and serum CRP levels or other CVD risk factors in healthy adult Korean(More)
Prostaglandin E (PGE) is the preferred agent for second-trimester pregnancy termination. Hypotension, bradycardia, ventricular arrhythmias, myocardial infarction, cardiac arrest and death associated with PGE have been reported. A case of acute myocardial infarction due to coronary vasospasm induced by PGE is described in the present report. The diagnosis(More)
BACKGROUND Delayed enhancement (DE) on cardiac magnetic resonance imaging (CMR) is a marker of myocardial fibrosis. The absence of DE in CMR is a predictor of left ventricular (LV) functional improvement in patients with non-ischemic cardiomyopathy (NICM), so in the present study it was investigated whether presence of DE has prognostic significance in(More)
BACKGROUND The pathophysiology of diastolic dysfunction is complex, but can be simply described as impaired LV myocardial relaxation and/or increased LV stiffness. The objective of this study is to clarify true normal left ventricular (LV) diastolic function and early stage of diastolic dysfunction before relaxation abnormality develops in patients with(More)
