AIMS The aim of this study was to compare the efficacy and safety of zotarolimus-eluting stents (ZES), sirolimus-eluting stents (SES) and paclitaxel-eluting stents (PES) in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). METHODS AND RESULTS This study was a prospective,(More)
To investigate the diagnostic potential of DNA methylation-based markers in tissue samples of DCIS, we examined the prevalence and extent of methylation in breast ductal carcinoma in situ (DCIS) samples from North American and Korean women. Quantitative multiplex-methylation specific PCR (QM-MSP) of ten genes was performed. The methylation level of APC1,(More)
BACKGROUND although intravascular ultrasound (IVUS) has been widely used for complex lesions during coronary intervention, IVUS for stenting at bifurcation lesions has not been sufficiently assessed. The aim of this study was to investigate the impact of IVUS guidance on long-term clinical outcomes during drug-eluting stent (DES) implantation for(More)
BACKGROUND Whether triple antiplatelet therapy is superior or similar to dual antiplatelet therapy in patients with acute ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention in the era of drug-eluting stents remains unclear. METHODS AND RESULTS A total of 4203 ST-segment elevation myocardial infarction patients(More)
BACKGROUND CX3CL1 is the only CX3C chemokine that can chemoattract T cells, natural killer (NK) cells, and dendritic cells (DCs). The role of CX3CL1 in breast carcinoma remains unknown. METHODS Immunohistochemical staining for CX3CL1, CD8, CD57, and CD1a was performed on 204 breast carcinoma specimens using tissue microarray blocks to determine whether(More)
OBJECTIVES Aspirin resistance is one of several possible explanations for limited efficacy or treatment failure of aspirin. However, the predictors of aspirin resistance are not well known. We therefore conducted a study of laboratory-defined aspirin resistance in Korean patients with ischemic stroke and considered a wide range of factors as possible(More)
HyperIgEemia and atopy have recently been reported to be related to various neurological diseases such as Hirayama disease and idiopathic myelitis. The aims of this study are to determine frequency of atopy or hyperIgEemia in idiopathic myelitis and to characterize the clinical and laboratory profiles of atopic myelitis (AM). From January 2006 to August(More)
OBJECTIVE We have noted that quantitative multiplex-methylation specific PCR (QM-MSP) analysis of a key panel of genes may be useful as an ancillary tool for ductal carcinoma in situ (DCIS) detection in breast tissue. In this study, we investigated aberrant promoter hypermethylation of four genes as a means to detect epigenetic alterations specific to(More)
Positron emission tomography (PET) with fluorine 18 fluorodeoxyglucose (FDG) is used to diagnose, stage, and monitor breast cancer. FDG PET has the capability to depict abnormal metabolic activity before any anatomic change occurs; however, in the absence of identifiable anatomic structures on PET images, it may be impossible to identify the location of(More)
OBJECTIVES This study sought to investigate the predictors and outcomes of side branch (SB) occlusion after main vessel (MV) stenting in coronary bifurcation lesions. BACKGROUND SB occlusion is a serious complication that occurs during percutaneous coronary intervention (PCI) for bifurcation lesions. METHODS Consecutive patients undergoing PCI using(More)
