Isolated rat pineal glands were incubated in vitro in a medium containing [14C]dopamine or [14C]tyrosine, and the tissue contents of 14C-labelled and total dopamine and noradrenaline were determined by HPLC followed by electrochemical detection and scintillation spectrometry. During incubation with [14C]dopamine, the labelled amine accumulated in pineal(More)
Rescue coronary angioplasty (PTCA) was employed as reperfusion strategy after unsuccessful intracoronary infusion of streptokinase in 13 patients with AMI complicated by cardiogenic shock (CS). Reperfusion defined as reestablishment of TIMI 3 degree flow in the infarct related artery and reduction in luminal narrowing to less than 50% was achieved in 8(More)
BACKGROUND The transradial approach for percutaneous coronary intervention (PCI) seems to be superior to transfemoral. The safety and efficacy of transradial approach for PCI in acute myocardial infarction is not well-established. METHODS Hundred patients with acute myocardial infarction qualified to PCI were randomly assigned to transradial (group I; n =(More)
BACKGROUND The role of incomplete revascularization (ICR) in patients with acute myocardial infarction (AMI) is controversial. We evaluated the impact of ICR on short- and long-term outcome in patients with AMI and multivessel disease (MVD) treated with percutaneous coronary interventions (PCI) during index hospital stay. METHODS Single-center(More)
BACKGROUND We sought to evaluate the influence of atrio-ventricular reentrant tachycardia (AVRT) on atrial pressures during tachycardia and the presence of atrial fibrillation (AF) in patients with preexcitation syndrome. METHODS The study population consisted of 88 patients (37 females, mean age 37.3 years) with left-sided accessory pathway and AVRT(More)
Dilated cardiomyopathy induces circulatory insufficiency with poor prognosis. Persistent tachyarrhythmias may be the cause of this disease. At particular high risk for heart damage and insufficiency are young people and children. The group of most dangerous arrhythmias consist of: incessant tachycardia in patients with preexcitation syndrome and(More)
The functional and morphological changes in myocardium of diabetic patients is caused by diabetic macroangiopathy, diabetic microangiopathy, autonomic neuropathy and metabolic disorders. Mechanism of these changes in the course of diabetes is not fully known. To determine whether there are myocardial ultrastructure differences between patients with diabetic(More)
One of the additional methods of coronary artery assessment is intravascular ultrasound (IVUS). Contrary to coronary angiography this relatively new technic provides new information including precise calculations of stenosis degree, morphology of atheromatous plaque and differentiation of its structure. Coronary angiography was performed in 54 years old(More)
