BACKGROUND The aim of this study was to assess the age-related differences in intravascular ultrasound (IVUS) findings of target lesions in patients with coronary artery disease. METHODS AND RESULTS The 1,009 patients who underwent IVUS imaging were grouped according to an increase of 10 years of age: Group I [<50 years (n=144)]; Group II [51-60 years(More)
BACKGROUND Almost all data on drug-eluting stents (DES) fracture have been derived from initial platform of first-generation DES such as Cypher Bx® (CBX) and Taxus Express®. However, incidence and clinical impact of fracture of newer DES platforms (including Cypher Select®, Taxus® Liberté™, Endeavor®, and Xience™ V) that have been used widely in current(More)
OBJECTIVES The aim of this study was to assess the incidence, predictors, and outcome of plaque prolapse (PP) after stent implantation in acute myocardial infarction. BACKGROUND The imaging characteristics of PP in patients with acute myocardial infarction are not well known. METHODS Intravascular ultrasound (IVUS) imaging was performed in 310 patients(More)
BACKGROUND/AIMS The usefulness of global longitudinal peak systolic strain (GLPSS) measurement by automated function imaging (AFI) in the prediction of perfusion status of infarct-related artery (IRA) before percutaneous coronary intervention (PCI) was evaluated. METHODS Sixty-nine patients with acute myocardial infarction (AMI) who underwent successful(More)
Hepatitis C virus (HCV)-encoded nonstructural protein 3 (NS3) possesses protease, NTPase, and helicase activities, which are considered essential for viral proliferation. Thus, HCV NS3 is a good putative therapeutic target protein for the development of anti-HCV agents. In this study, we isolated specific RNA aptamers to the helicase domain of HCV NS3 from(More)
There are limited data regarding the role of coronary computed tomographic angiography (CCTA) in asymptomatic patients with type 2 diabetes mellitus. We analyzed 557 asymptomatic type 2 diabetic patients who underwent CCTA. Cardiac event was defined as a composite of cardiac death, nonfatal myocardial infarction, acute coronary syndrome requiring(More)
BACKGROUND The risk of excessive bleeding prompts physicians to stop multiple antiplatelet agents before minor surgery, which puts coronary stenting patients at risk for adverse thrombotic events. HYPOTHESIS We hypothesized that most dental extractions can be carried out safely without stopping multiple antiplatelet agents. METHODS All dental extraction(More)
BACKGROUND The purpose of this study was to determine the clinical and laboratory characteristics in patients with acute myocardial infarction (AMI) associated with coronary vasospasm. METHODS AND RESULTS Consecutive 231 patients with documented coronary vasospasm by ergonovine provocation test but with a normal-appearing coronary angiogram were divided(More)
Patent ductus arteriosus (PDA) is a rare clinical finding in adult patients. Considering the increase in cases of PDA discovered incidentally on echocardiograms at young ages, and the life-shortening effect of PDA, it is rare to diagnose PDA in old patients. We report a case of an 80-year-old patient who experienced symptoms of congestive heart failure(More)
There are limited data on the impact of diabetes mellitus (DM) on the risk of subclinical atherosclerosis. Therefore, we sought to investigate the impact of DM on the risk of subclinical atherosclerosis in asymptomatic subjects. We analyzed 2,034 propensity score-matched asymptomatic subjects who underwent coronary computed tomographic angiography (mean age(More)
