AIMS Acutely decompensated heart failure (ADHF) leads to neurohumoral activation potentially affecting vascular tone and organ perfusion and may be linked to unfavourable outcome. Global haemodynamic, clinical, and laboratory parameters may severely underestimate tissue hypoperfusion. Therefore, the purpose of this study was to evaluate microvascular flow(More)
The study was done to determine the clinical feasibility and reproducibility of tissue Doppler echocardiography (TDE) with strain rate imaging (SRI) at rest and under physical exercise in healthy young individuals and to report normal values for parameters of regional myocardial function under exercise. Forty-five young volunteers (age 9–29 years) underwent(More)
INTRODUCTION Endothelial microparticles (EMP) are small membrane vesicles that originate from activated or apoptotic endothelial cells. Although the exact mechanism of EMP function is still relatively unknown, it has been shown that they modulate inflammatory processes, coagulation and vascular function. In this study we hypothesized that transient hypoxia(More)
BACKGROUND Ventricular dysfunction represents one of the major problems in the long-term follow-up of patients after atrial repair for dextrotransposition of the great arteries. We aimed to study the role of tissue Doppler derived isovolumic acceleration (IVA) to detect early myocardial dysfunction in these patients. METHODS Twenty-four patients with(More)
BACKGROUND In this randomized trial, strut coverage and neointimal proliferation of a therapy of bare metal stents (BMSs) postdilated with the paclitaxel drug-eluting balloon (DEB) was compared with everolimus drug-eluting stents (DESs) at 6-month follow-up using optical coherence tomography. We hypothesized sufficient stent coverage at follow-up. METHODS(More)
Hypoxia frequently associated with certain physiologic and pathologic conditions influences numerous cellular functions. Because the effects of short-term hypoxia are incompletely understood, we examined phagocytosis and cytokine production as well as the activation of the transcription factors HIF-1 and NFκB in peripheral blood cells of healthy volunteers(More)
BACKGROUND Indications for prophylactic implantable cardioverter-defibrillator implantation in patients with nonischemic dilated cardiomyopathy (DCM) are based on left ventricular (LV) ejection fraction (LVEF), although LVEF has limited ability to predict arrhythmias. It has recently been shown that strain echocardiography can predict ventricular(More)
Elevation of cardiac troponin I (cTnI) is a well-known complication after percutaneous coronary interventions (PCI). The aims of this study were to quantify the extent of coronary microembolization during elective PCI, to identify predisposing anatomical and procedural factors, and to evaluate its impact on long-term outcome in diabetic patients with a high(More)
OBJECTIVE Myocardial dysfunction due to coronary arterial lesions is an important complication after Kawasaki syndrome in childhood. Tissue Doppler echocardiography, and strain rate imaging, have shown their value in detecting regional myocardial dysfunction in coronary arterial disease. We aimed to examine the diagnostic value of these methods in patients(More)
The aim of this prospective study was to assess the value of speckle tracking echocardiographic (2D-STE) parameters to predict response to heart failure therapy in patients with dilated cardiomyopathy (DCM). Eighty-seven patients (mean age 51 ± 13 years) with DCM, defined as ejection fraction (EF) <45 %, left ventricular (LV) end-diastolic diameter >112 %(More)
