Nevertheless, the disparity in the lesion geometry in both depth and width is the major pitfall in the use of RF currents. The objective of this study was to differentiate the shape and size of long lesions created by three(More)
Cardiopulmonary bypass (CPB) is associated with oxidative stress. This study examined antioxidant levels in adults undergoing CPB surgery and their correlation with clinical variables. Arterial blood samples were obtained from 27 patients undergoing CPB. The time-course variation of vitamin C (spectrofluorimetry), alpha-tocopherol and retinol (HPLC) levels(More)
Background The amount of epicardial adipose tissue (EAT) has been associated with the presence of atherosclerotic disease but its role in assessing the risk of obstructive coronary artery disease (CAD) and its relationship with other cardiovascular risk factors is not fully established. We hypothesized that EAT quantified by cardiac magnetic resonance (CMR)(More)
BACKGROUND Acute renal dysfunction (ARD) may appear in heart transplant (HTx) patients both in the early postoperative period and during follow-up, even after several years. CD25 is a subunit of the interleukin-2 receptor which is found exclusively on activated CD4 T lymphocytes. CD25 is crucial for clonal expansion of anti-allograft host lymphocytes that(More)
