BACKGROUND Limited data are available regarding the direct comparison of angiographic and clinical outcomes after percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) for chronic total occlusion (CTO). METHODS AND RESULTS A prospective, randomized, multicenter trial was conducted to evaluate the non-inferiority of a zotarolimus-eluting(More)
BACKGROUND Limited availability of noninvasive and biologically precise diagnostic tools poses a challenge for the evaluation and management of patients with myocarditis. METHODS AND RESULTS The feasibility of cardiovascular magnetic resonance (CMR) imaging with magneto-fluorescent nanoparticles (MNPs) for detection of myocarditis and its effectiveness in(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)
BACKGROUND Coronary spasm seems to be associated with coronary nitric oxide deficiency. OBJECTIVES We investigated whether the Glu298Asp polymorphism in the endothelial nitric oxide synthase (eNOS) gene is a definite risk factor for coronary spasm and whether diffuse spasm involving normal-looking coronary artery correlates significantly with the(More)
Receptor for advanced glycation end products (RAGE) and connective tissue growth factor (CTGF) play a key role in diabetic myocardial fibrosis, and peroxisome proliferator-activated receptor-γ (PPAR-γ) activation has been reported to reduce RAGE and CTGF expression. This study investigated the effects of the PPAR-γ agonist, rosiglitazone, on myocardial(More)
Magneto-fluorescent silica nanoparticles were conjugated with cetuximab for the targeting and imaging of colon cancer. In this study, cetuximab-conjugated magneto-fluorescent nanoparticles (MFSN-Ctx) could specifically target colon cancer cells that expressed EGFR on their cell membranes, and specific fluorescence was detected. MFSN-Ctx produced significant(More)
BACKGROUND Inadequate myocardial tissue perfusion after successful revascularization in ST-segment elevation myocardial infarction (STEMI) is associated with worse clinical outcomes. We investigated whether the plasma B-type natriuretic peptide (BNP) level on admission could predict the status of myocardial tissue perfusion in patients who underwent primary(More)
BACKGROUND The roles of soluble and endogenous secretory receptors for advanced glycation endproducts (sRAGE and esRAGE, respectively) in plaque vulnerability are unknown in patients with acute myocardial infarction (AMI). METHODS AND RESULTS We enrolled 54 patients with AMI (27 patients had type 2 diabetes mellitus [DM]) who had undergone primary(More)
BACKGROUND Left ventricular hypertrophy (LVH) has been known as an important predictor of prognosis of cardiovascular disease. Carboxy-terminal propeptide of procollagen type I (PIP) is related with myocardial fibrosis. We sought to analyze the differences in the characteristics of LVH, myocardial fibrosis, and LV functions among hypertension (HBP),(More)
BACKGROUND A low level of high-density lipoprotein cholesterol (HDL-C) is strongly associated with cardiovascular events. However, the significance of HDL-C after statin therapy on the outcome of patients who have undergone percutaneous coronary intervention (PCI) with drug eluting stents (DES) is unclear. OBJECTIVES To investigate the significance of(More)
