Recent studies have indicated increased ventricular repolarisation dispersion in haemodialysis (HD) patients. The purpose of this study was to estimate the effect of the HD process on parameters of regional and transmyocardial repolarisation inhomogeneities. Thirty-two selected HD patients (without relevant diseases and medication known to affect the QT(More)
BACKGROUND This study was performed to investigate the relationship between elastic properties of aorta and left atrium volume index (LAVI) in hemodialyzed (HD) patients. METHODS Study group was consisted of 73 patients (age 51,6 ± 7,6 years) treated by hemodialysis. In all patients standard echocardiography was performed. Aortic stiffness index (ASI) was(More)
This study was performed to investigate the relationship between left atrium (LA) volume index (LAVI) and left ventricle electrical activity presumably repolarization in end-stage renal disease patients. Study group was consisted of 120 dialyzed patients divided into two subgroups: 57 (age 50.7 ± 7.1) were on continuous ambulatory peritoneal dialysis (CAPD)(More)
Given that cardiac disease is the leading cause of mortality in hemodialysis (HD) patients, identification of patients at risk for cardiac mortality is crucial. The aim of this study was to determine if positive T-wave amplitude in lead aVR (TaVR) was predictive of cardiovascular (CV) mortality and sudden cardiac death (SCD) in a group of HD patients. After(More)
AIM Study was designed to assess relationship between aortic compliance and homogeneity of heart electrical activity in dialysis patients. METHODS Study group was consisted of 120 dialyzed patients; 57 (age 50,7 ± 7,1) were on continuous ambulatory peritoneal dialysis (CAPD) and 73 (age 51,6 ± 7,6) were hemodialyzed (HD). Three-dimensional(More)
BACKGROUND The P-wave signal-averaged electrocardiogram (SAECG) is a non-invasive technique considered to indicate an increased risk for paroxysmal atrial fibrillation. The study was designed to evaluate the effect of the haemodialysis (HD) process on SAECG parameters in the group of selected HD patients. METHODS Forty-seven HD patients (without relevant(More)
BACKGROUND For patients with end-stage renal disease who are not candidates for fistula, dialysis access grafts are the best option for chronic haemodialysis. However, polytetrafluoroethylene arteriovenous grafts are prone to thrombosis, infection, and intimal hyperplasia at the venous anastomosis. We developed and tested a bioengineered human acellular(More)
BACKGROUND Abnormal values of the spatial angle between the directions of ventricular depolarization and repolarization (QRS-T) predict potently arrhythmic events and mortality in various patients groups. The study was designed to estimate QRS-T in a group of peritoneal dialysis (PD) patients, and to assess the possible association between QRS-T and(More)
The study was designed to evaluate the potential link between low-T3 syndrome and signal-averaged ECG parameters (SAECG) in a group of hemodialyzed patients (HD-pts). 52 selected HD-pts (without relevant thyroid and cardiac diseases) were included. SAECGs were performed postdialysis together with evaluating free triiodothyronine (fT3), free thyroxine (fT4),(More)
AIM The aim of this study was to evaluate the usefulness of iodine-123 metaiodobenzylguanidine (I-mIBG) myocardial scintigraphy in the detection of cardiac sympathetic neuropathy in haemodialysed patients without relevant cardiovascular symptoms. MATERIALS AND METHODS A group of 20 haemodialysed patients were examined. The stress/rest myocardial perfusion(More)
