BACKGROUND AND OBJECTIVES Stress-induced cardiomyopathy (SCM) is characterized by a transient left ventricular (LV) dysfunction due to emotional and physical stress. There are limited data about the clinical characteristics in Korean patients. We sought to clarify the clinical features and prognosis in patients with SCM. SUBJECTS AND METHODS We reviewed(More)

Background and Objectives : Clopidogrel resistance or low-responsiveness may be associated with recurrent ath-erothrombotic events after drug-eluting stent (DES) implantation. We prospectively evaluated the association between clopidogrel resistance assessed by the Verifynow TM P 2 Y 12 assay (Accumetrics, San Diego, CA, USA) and stent thrombosis (ST) or(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)
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 Stented segment length is a predictive factor for restenosis and stent thrombosis still in the drug-eluting stent (DES) era, and the benefit of routine intravascular ultrasound (IVUS) is still unclear. The aim of the present study was to investigate whether IVUS-guided percutaneous coronary intervention (PCI) improved the vascular(More)
BACKGROUND AND OBJECTIVES Transradial coronary angiography and intervention are increasing in frequency due to lower major vascular access site complications and the potential for early mobilization. However, the small size of the radial artery (RA) is a major limitation of this technique. A sheathless guiding catheter (GC) has recently been introduced that(More)
BACKGROUND AND OBJECTIVES We evaluated the effectiveness of genotype- and phenotype-directed individualization of P2Y12 inhibitors to decrease high on-treatment platelet reactivity (HOPR). SUBJECTS AND METHODS Sixty-five patients undergoing percutaneous coronary intervention for non-ST elevation acute coronary syndromes were randomly assigned to genotype-(More)
BACKGROUND AND OBJECTIVES The aim of our study was to compare the values of brachial-ankle pulse wave velocity (baPWV) measured with two different non-invasive methods as predictors of coronary artery disease (CAD) in patients who had undergone coronary angiography. SUBJECTS AND METHODS From 6373 patients who visited our laboratory for non-invasive(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)
Echocardiography is widely used to carry out non-invasive cardiac evaluation at the bedside and provides useful real-time information about hemodynamics. It can also be used to diagnose a stress-induced cardiomyopathy and its complications such as shock, heart failure and apical thrombus. Early diagnosis and management are important to prevent possible(More)
