We report a rare case of primary antiphospholipid syndrome (APS) in a 43-year-old man presenting as recurrent acute coronary stent thrombosis and complicated by three myocardial infarctions. As illustrated in this report, in APS patients recurrent life-threatening arterial thrombotic events may occur in spite of recommended anticoagulant therapy. We(More)
INTRODUCTION Calcific aortic valve disease is associated with inflammation and calcification, thus the osteoprotegerin (OPG), receptor activator of nuclear factor κB (RANK) and its ligand (RANKL) system involved in osteoclastogenesis and inflammation may play a significant role in valve degeneration. OBJECTIVES The aim of this study was to assess whether(More)
Reperfusion injury is of increasing importance due to new techniques of restoring blood flow to acutely ischaemic areas by means of thrombolysis, angioplasty, or acute coronary artery bypass surgery. Reperfusion of ischaemic myocardium can results in the acceleration of surrounding reversibly injured myocytes and endothelial cells to irreversibly injured(More)
Calcific aortic valve stenosis (CAVS) is an actively regulated process that involves mechanisms of bone development, including the receptor activator of nuclear factor κB, its ligand, and osteoprotegerin (RANK/RANKL/OPG) regulatory system. The aim of this study was to investigate whether the levels of circulating OPG and RANKL can be correlated with some(More)
There are significant differences between functioning of transplanted and healthy hearts. Assessment of such a heart and therapeutic possibilities in heart recipients require understanding of these differences. Vegetative denervation of heart increases its sensitivity to the circulation humoral substances, especially catecholamines. In the early(More)
A case of a 70-year-old female with hypertension, atrial fibrillation and angina pectoris, admitted to the hospital due to echocardiographically detected left atrial tumour, is presented. Differential diagnosis included thrombus, myxoma, infectious or neoplastic tumour. The patients underwent surgery. Histopathological examination revealed the presence of(More)
UNLABELLED The aim of the study was to analyse the clinical course of pts with end stage disease (ESD) in the period of four years. The study population consisted of 152 pts (132 males, 20 females) at the age of 17-66 years (mean = 48.8 year SD = 9.1) primarily qualified to the heart transplantation (HTX). We analysed the ethiology of cardiac failure, the(More)
Calcified heart valves display a significant imbalance in tissue content of trace and essential elements. The valvular calcification is an age-related process and there are data suggesting involvement of lipids. We studied elemental composition and lipid distribution in three distinct regions of calcified human aortic valves, representing successive stages(More)
