BACKGROUND Current guidelines recommend coronary artery bypass graft surgery (CABG) when treating significant de novo left main coronary artery (LM) stenosis; however, percutaneous coronary intervention (PCI) has a class IIa indication for unprotected LM disease in selected patients. This analysis compares 5-year clinical outcomes in PCI- and CABG-treated(More)
Major nuclear envelope abnormalities, such as disruption and/or presence of intranuclear organelles, have rarely been described in cardiomyocytes from dilated cardiomyopathy (DCM) patients. In this study, we screened a series of 25 unrelated DCM patient samples for (a) cardiomyocyte nuclear abnormalities and (b) mutations in LMNA and TMPO as they are two(More)
BAG3 gene mutations have been recently implicated as a novel cause of dilated cardiomyopathy (DCM). Our aim was to evaluate the prevalence of BAG3 mutations in Polish patients with DCM and to search for genotype-phenotype correlations. We studied 90 unrelated probands by direct sequencing of BAG3 exons and splice sites. Large deletions/insertions were(More)
BACKGROUND Modern Polish medicine offers patients various treatments for end-stage treatment-resistant heart failure. Methods applied at the right time before the occurrence of irreversible changes in organs give a chance for survival and prolong life. CASE REPORT Here, we report on the safety and efficacy of the sequential use of the above treatments in(More)
AIMS Having several recently published reports on increased rate of cardiac perforation with some lead models as background, we assess the relation between cardiac perforations and models of leads used. METHODS AND RESULTS All pacing and defibrillation leads implantations between 1 January 2007 and 31 March 2008 were analysed retrospectively. There were(More)
Many bacterial species can be a cause of various heart diseases, such as: Borrelia burgdorferi sensu lato, Coxiella burnetii and Bartonella spp. The aim of the present studies was to establish if any tick-borne infections can contribute to serious heart disorders resulting in the need for heart transplantation. Myocardium, aortic and mitral valve samples(More)
We analysed the architecture of cardiomyocyte nuclei lacking lamin A activity in three patients with dilated cardiomyopathy. The diagnosis was established on the basis of clinical and electrophysiological examinations, chest radiography and electrocardiography. An ultrastructural study of affected cardiomyocytes showed dramatic alterations in nuclear(More)
BACKGROUND The aim of this study was to assess the quality of life of patients before and after heart transplantation (HTX). MATERIAL AND METHODS We included 63 patients after a heart transplant under the care of the Transplantation Clinic. The authors' questionnaire was used, which consisted of 2 parts: questions concerning the life of patients before(More)
BACKGROUND The etiology of peripartum cardiomyopathy (PPCM) is not well understood. Potential causal mechanisms include infection, autoimmune disease, and abnormal response to the hemodynamic stress of pregnancy. Recently it was shown that the development of PPCM in an experimental model is associated with the generation of a cleaved antiangiogenic and(More)
