OBJECTIVE Experimental evidence suggests that exenatide, a glucagon-like peptide 1 receptor analogue, has significant cardiovascular protective effects in various conditions. We examined whether routine use of exenatide at the time of primary percutaneous coronary intervention would reduce infarct size in patients with ST-segment-elevation myocardial(More)
This study was designed to determine the effect of green tea consumption in patients with chronic kidney disease (CKD) on flow-mediated endothelium-dependent vasodilation (FMD) and the number of circulating endothelial progenitor cells (EPCs). Forty patients with CKD requiring chronic dialysis were enrolled. The patients were divided into two groups: the(More)
Lysophosphatidylcholine (LPC) generated from oxidized low-density lipoprotein by lipoprotein-associated phospholipase A2 plays a key role in plaque inflammation and vulnerability. Endothelial progenitor cells (EPCs) can repair injured endothelium and exert anti-inflammatory effects of vulnerable plaque. We study the impact and mechanisms of LPC on UEA-1 and(More)
The aim of this study was to determine whether assessment of global longitudinal strain (GLS) before revascularization could predict adverse cardiac events after ST-segment elevation myocardial infarction (STEMI). In addition, the relation between GLS and cardiac biomarkers was investigated. From July 2006 through December 2009, 98 patients with first STEMI(More)
BACKGROUND Chronic kidney disease (CKD) is a factor of low response to clopidogrel. We sought to assess the functional impact of cilostazol in CKD patients with undergoing hemodialysis. METHODS Seventy-four patients with CKD undergoing hemodialysis and percutaneous coronary intervention were enrolled. Patients were randomly assigned to receive clopidogrel(More)
OBJECTIVE The purpose of this study was to evaluate whether exenatide administration can prevent impairment in endothelium-dependent vasodilatation induced by ischemia-reperfusion (IR) injury and whether this effect is mediated by K(ATP) channel opening. METHODS AND RESULTS In a double-blind, placebo-controlled, crossover design, 20 volunteers were(More)
OBJECTIVES Acute or chronic intake of polyphenol-rich foods has been reported to improve endothelial function. Quercetin, found abundantly in onion, is a potent antioxidant flavonoid. The aim of this study was to investigate whether consumption of onion peel extract (OPE) improves endothelial function in healthy overweight and obese individuals. METHODS(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)
The relation between remodeling and left ventricular (LV) torsion has not yet been fully investigated. The aim of this study was to determine whether LV torsion assessed by speckle tracking imaging can predict progressive LV dilation after acute myocardial infarction (AMI). From January 2006 through June 2008, 91 patients with AMI who were successfully(More)
