BACKGROUND An increasing number of people over 60 years of age living world-wide undertake appropriate actions in order to identify factors to optimize their health. OBJECTIVE The study was aimed at evaluating nutritional patterns, biochemical parameters (TC, HDL, LDL, TG, glucose) and anthropometric parameters (BMI, waist circumference, arm(More)
OBJECTIVE Whether right ventricular dysfunction affects clinical outcome after coronary artery bypass grafting with or without surgical ventricular reconstruction is still unknown. The aim of the study was to assess the impact of right ventricular dysfunction on clinical outcome in patients with ischemic cardiomyopathy undergoing coronary artery bypass(More)
BACKGROUND The Surgical Treatment for Ischemic Heart Failure (STICH) randomized trial was designed to identify an optimal management strategy for patients with ischemic cardiomyopathy. Baseline echocardiographic examinations were required for all patients. The primary aim of this report is to describe the baseline STICH Echocardiography Core Laboratory(More)
OBJECTIVE It has been recently suggested that perivascular tissue (PVT) releases hypothetic adipocyte- or adventitia-derived relaxing factor. The aim of the study was to assess anticontractile properties of perivascular tissue of human internal thoracic artery (ITA) and to check if this activity is nitric oxide (NO)- or prostacyclin-dependent. We also(More)
BACKGROUND Diazoxide has been shown to confer significant myocardial protection in many experiments. This study was designed to assess its influence on the structural injury and functional recovery of human myocardium subjected to hypoxia/reoxygenation in vitro. METHODS The isolated electrically driven human right atrial trabeculae, obtained during(More)
BACKGROUND The aim of this study was to compare cardiac magnetic resonance imaging (CMR) with 2-dimensional echocardiography (2D echo) in the assessment of left ventricle (LV) function parameters and mass in patients with ischemic heart disease and severely depressed LV function. Although 2D echo is commonly used to assess LV indices, CMR is the(More)
OBJECTIVE The studies showing the superior characteristics of ITA graft and its impact on the clinical results of coronary artery surgery were performed with ITA harvested almost exclusively as a pedicle. This study assesses the impact of ITA skeletonization on its innervation and reactivity. METHODS Segments of skeletonized and non-skeletonized ITA were(More)
OBJECTIVES The study was designed to assess whether diazoxide-mediated cardioprotection might be used in human subjects during cardiac surgery. METHODS Forty patients undergoing coronary artery bypass grafting were randomized to receive intermittent warm blood antegrade cardioplegia supplemented with either diazoxide (100 micromol/L) or placebo (n = 20 in(More)
BACKGROUND It is not clear what the optimal timing of diazoxide administration for cardioprotection in human myocardium is. We aimed to establish it. We next checked whether protection depended on adenosine triphosphate (ATP)-inhibited potassium (KATP) channels. METHODS Isolated human right atrial trabeculae were subjected to 90-minute hypoxia and(More)
A case of a 74 year old patient with a history of CABG with temporary epicardial cardiac pacing, is described. Five years later the patient developed wound infection. Computerised tomography revealed the presence of mediastinal abscess containing surgical material. The patients underwent surgical removal of the abscess with a distal part of an epicardial(More)
