Neurohormones (NHs) in the cascade of the arginine vasopressin (AVP) system have drawn particular attention in the recent years. Copeptin, the C-terminal portion of provasopressin, is a novel NH of the AVP system, and is known to be co-released with AVP from hypothalamus (neurohypophysis). As a surrogate marker of the AVP system, copeptin has gradually(More)
BACKGROUND Congenital anomalies of the coronary arteries are rarely encountered in patients undergoing cardiac catheterization. In patients undergoing coronary angioplasty or cardiac surgery, angiographic recognition of coronary anomalies is important for the proper management of these patients. METHOD We retrospectively reviewed the records of 12,844(More)
Oxidative stress plays a crucial role in a variety of clinical settings of atherogenesis, and mediates many pathways linked to atherosclerosis and inflammation. gamma-Glutamyltransferase (GGT), an enzyme responsible for the extracellular catabolism of antioxidant glutathione, may directly take part in atherogenesis and evolve as a potential biochemical risk(More)
BACKGROUND Levosimendan is a relatively new cardiac inotropic agent with calcium sensitizing activity. This study was conducted to investigate the effects of levosimendan (L) and dobutamine (D) on renal function in patients hospitalized with decompensated heart failure (HF). METHOD The present study included 88 consecutive patients hospitalized with(More)
BACKGROUND Recent clinical observations have demonstrated that the beneficial effects of statins are not limited to LDL lowering effect. They have also favourable effects on platelet activation, endothelial function, inflammation, and coagulation cascade. AIM To investigate the effects of statins on mean platelet volume (MPV) which is a simple measure of(More)
Severe heart failure represents a major source of morbidity and mortality. Poor right ventricular function is an independent prognostic marker for mortality in patients with chronic heart failure. In this study, levosimendan (L) and dobutamine (D) in patients with severe chronic biventricular failure were compared. Forty consecutive patients, who were(More)
OBJECTIVE Crimean-Congo hemorrhagic fever (CCHF) is an acute viral hemorrhagic fever with a high mortality rate. Despite increasing knowledge about viral hemorrhagic fevers, the pathogenesis of CCHF and causes of death have not been well described. In this study, we aimed to evaluate the cardiac functions of CCHF patients. METHODS This prospective study(More)
INTRODUCTION Atrial fibrillation (AF) is the most frequently encountered chronic arrhythmia associated with significant morbidity. It is generally encountered in the elderly, and will presumably become more prevalent in the future due to the increasing proportion of the elderly in the population. Major studies on AF have demonstrated no significant(More)
