BACKGROUND AND OBJECTIVES The prognostic value of biochemical markers and the resolution of ST-segment elevation on electrocardiogram are well established. However, how a combination of these two tools affects the evaluation of risk stratification has not yet been evaluated. SUBJECTS AND METHODS Between January 2006 and June 2008, 178 consecutive patients(More)
Background. Atrial fibrillation (AF) is the most common form of arrhythmia. Several trials have suggested that acupuncture may prevent AF. However, the efficacy of acupuncture for AF prevention has not been well investigated. Therefore, we designed a prospective, two-parallel-armed, participant and assessor blinded, randomized, sham-controlled clinical(More)
This study aimed to evaluate the effects of percutaneous coronary intervention (PCI) on short- and long-term major adverse cardiac events (MACE) in elderly (>75 yr old) acute myocardial infarction (AMI) patients with renal dysfunction. As part of Korea AMI Registry (KAMIR), elderly patients with AMI and renal dysfunction (GFR<60 mL/min) received either(More)
Many observational studies showed hogh-density lipoprotein cholesterol (HDL-C) is a strong inverse predictor of cardiovascular (CV) outcome. However, recent large clinical trials evaluating therapies to raise HDL-C level in those already on statin therapy have been discouraging. This complexity is not well-known.A total of 28,357 acute myocardial infarction(More)
OBJECTIVE Although dipeptidyl peptidase-4 (DPP-4) inhibitors have been suggested to have a non-glucoregulatory protective effect in various tissues, the effects of long-term inhibition of DPP-4 on the micro- and macro-vascular complications of type 2 diabetes remain uncertain. The aim of the present study was to investigate the organ-specific protective(More)
BACKGROUND Identifying the transmural extent of myocardial necrosis and the degree of myocardial viability in acute myocardial infarction (AMI) is important clinically. The aim of this study was to assess myocardial viability using two-dimensional speckle tracking imaging (2D-STI) in patients with AMI. METHODS 2D-STI was performed at initial presentation,(More)
BACKGROUND Atrial fibrillation (AF) is known to be associated with several pathophysiological mechanisms including endothelial dysfunction of the heart and arterial vessels. Recent evidence suggests that new oral anticoagulant (NOAC) treatment may improve endothelial function and the inflammatory process involved in atherosclerosis in AF patients. This(More)
BACKGROUND The coronary artery calcium (CAC) and aortic arch calcification (AoAC) are individually associated with cardiovascular disease and outcome. This study investigated the predictive value of AoAC combined with CAC for cardiovascular diagnosis and outcome in patients with angina. METHODS A total of 2018 stable angina patients who underwent chest(More)
Although acupuncture researchers have conducted studies using rats for decades, there is no established method for controlling the animals while performing acupuncture. Some choose to use general anesthesia [1]; some prefer light sedation [2]; many opt to use tools such as tubes, bags [3, 4], or clothing holders [5]; while others simply immobilize them by(More)
Although dobutamine stress echocardiography (DSE) is a well-defined tool for the diagnosis of coronary artery disease (CAD), false-negative and false-positive results still occur. This study investigated the diagnostic role of layer-specific analysis using 2-dimensional speckle-tracking echocardiography (STE) during DSE.A total of 121 patients who underwent(More)
