OBJECTIVES This study compared the prognostic role of high on-treatment platelet reactivity (HTPR) in predicting thrombotic events in a Korean population undergoing percutaneous coronary intervention (PCI) in the acute myocardial infarction (AMI) and non-AMI setting. BACKGROUND The prognostic significance and optimal cutoff of HTPR might differ according(More)
Recent studies suggest that the intracoronary administration of bone marrow (BM)-derived mesenchymal stem cells (MSCs) may improve left ventricular function in patients with acute myocardial infarction (AMI). However, there is still argumentative for the safety and efficacy of MSCs in the AMI setting. We thus performed a randomized pilot study to(More)
BACKGROUND A syndrome variously combining peripheral neuropathy, visceromegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS syndrome) is a rare variant of plasma cell dyscrasia with multisystemic manifestations. Acute ischemic strokes in patients with POEMS syndrome have rarely been reported, and the pathophysiologic mechanism of this(More)
BACKGROUND Q waves on a 12-lead electrocardiography (ECG) are considered to be classic hallmarks of prior myocardial infarction. However, one study suggested that the fragmented QRS complex (fQRS) on ECG is a highly sensitive and specific marker of myocardial scarring on a nuclear stress test. The study aimed to investigate the diagnostic accuracy of(More)
Ginsenoside Rb1 is the most predominant ginsenoside in Panax species (ginseng) and the hydrolysis of this ginsenoside produces pharmaceutically active compounds. Caulobacter leidyia GP45, one of the isolates having strong β-glucosidase-producing activity, converted ginsenoside Rb1 to the active metabolites by 91%. The structures of the resultant metabolites(More)
Carotid intima-media thickness (CIMT) is considered as a surrogate marker for cardiovascular disease (CVD). We determined the normative value of CIMT and correlates of CVD risk factors and Framingham risk score (FRS) in Korean rural middle-aged population. We measured CIMT with a B-mode ultrasonography in 1,759 subjects, aged 40 to 70 yr, in a(More)
BACKGROUND There are conflicting data on the use of cilostazol as triple antiplatelet therapy (TAPT) for improving clinical outcomes after drug-eluting stent implantation. We aimed to evaluate whether 3-month use of cilostazol in addition to dual antiplatelet therapy (DAPT) improved clinical outcomes in patients with long or multivessel coronary artery(More)
We used the combined technique of functional magnetic resonance imaging (fMRI) and transcranial magnetic stimulation (TMS) to observe changes that occur in adult brains after the practice of stringed musical instruments. We carried out fMRI on eight volunteers (aged 20-22 years): five novices and three individuals who had discontinued practice for more than(More)
BACKGROUND AND OBJECTIVES The objective of this study was to determine if urinary levels of 8-iso-prostaglandin F2α (8-iso-PGF2α) and 8-hydroxydeoxyguanine (8-OHdG) could be used as markers of the oxidative stress in significant coronary artery disease (CAD). SUBJECTS AND METHODS We conducted a case-control study in 104 subjects assessed by coronary(More)
BACKGROUND Studies investigating the clinical outcome of intravascular ultrasound (IVUS)-guided primary percutaneous coronary intervention (PPCI) in patients with ST-segment elevation myocardial infarction (STEMI) show conflicting results. The aim of our study was to evaluate whether IVUS-guidedPPCI with drug-eluting stents (DESs) in STEMI patients improves(More)
