BACKGROUND AND OBJECTIVES S100A12 is an endogenous receptor ligand for advanced glycation end products. Cardiovascular disease remains a major cause of morbidity and mortality in patients with chronic kidney disease. In this study, we report cross-sectional data on 550 hemodialysis patients and assess the relationship between plasma S100A12 level and(More)
The incidence of cardiac death is higher among patients receiving dialysis compared with the general population. Although obstructive coronary artery disease is involved in cardiac deaths in the general population, deaths in hemodialysis patients occur in the apparent absence of obstructive coronary artery disease. To study this further, we prospectively(More)
BACKGROUND We prospectively investigated whether cardiac autonomic imbalance is associated with sudden cardiac death (SCD) among a group of hemodialysis patients with left ventricular hypertrophy (LVH). METHODS In a prospective cohort study, we enrolled 196 asymptomatic patients on chronic hemodialysis who had LVH as determined by echocardiography and had(More)
BACKGROUND/AIMS De novo coronary atherosclerosis may be involved in the poor prognosis after percutaneous coronary artery intervention (PCI) in hemodialysis patients. We aimed to clarify the factors associated with de novocoronary lesion in this population. METHODS We enrolled 106 patients on hemodialysis (72 men, 34 women; mean age, 65.4 +/- 8.9 years),(More)
We investigated whether chronic intravenous administration of l-carnitine could improve myocardial fatty acid imaging in patients on maintenance hemodialysis. We enrolled 72 hemodialysis patients who had impaired myocardial fatty acid imaging and left ventricular dysfunction not based on coronary lesion. l-Carnitine (1,000 mg) was intravenously administered(More)
BACKGROUND Tumor necrosis factor (TNF)-alpha causes hypertrophic as well as negative inotropic effects on cardiac myocytes. Circulating TNF-alpha levels are reported to be elevated in end-stage renal disease (ESRD) patients undergoing maintenance hemodialysis (HD). We investigated whether increased circulating TNF-alpha is associated with left ventricular(More)
BACKGROUND Patients with diabetic nephropathy are likely to have neurological complications including cardiovascular autonomic dysfunction, which is related to increased risk of mortality. We investigated whether cardiovascular autonomic neuropathy is associated with left ventricular hypertrophy (LVH) in diabetic haemodialysis patients. METHODS Holter(More)
BACKGROUND AND AIMS To compare the prognosis of chronic hemodialysis patients with or without parathyroidectomy. METHODS Among 158 chronic hemodialysis patients who underwent total parathyroidectomy between July 1998 and April 2009, 88 patients were matched with 88 controls for sex, age, underlying disease and prior dialysis history. Then a retrospective(More)
BACKGROUND Survival after invasive coronary revascularization is worse in patients with chronic kidney disease than in patients without chronic kidney disease. We examined whether oral administration of nicorandil, a hybrid nitrate and adenosine triphosphate-sensitive potassium channel opener, could improve outcome after coronary revascularization in(More)
BACKGROUND Coronary artery disease contributes significantly to mortality in end-stage renal disease (ESRD) patients. Single-photon emission computed tomography (SPECT) using an iodinated fatty acid analogue, iodine-123-methyl iodophenylpentadecanoic acid (123I-BMIPP), can assess fatty acid metabolism in the myocardium. We investigated the ability of(More)
