After a two-year period of the frequent detection of prednisolone-positive bovine urine samples in the Italian region of Lombardy, studies were initiated to investigate the source. Because the majority of positive samples were detected at the slaughterhouse, researchers hypothesised that, together with increased cortisol and cortisone, a small quantity of(More)
It is established that bovine urine can result positive for boldenone and androstadienedione in consequence of faecal contamination. The simple transfer of steroids to urine is one minor aspect of faecal contamination. A high de novo production of steroids in faeces after deposition and in faeces-contaminated urine is almost certainly due to microbial(More)
BACKGROUND We investigated the possibility that transient coronary slow-flow as assessed during coronary angiography in patients with cardiac syndrome X may impair myocardial perfusion and the effects of this phenomenon on long-term prognosis. METHODS From 50 consecutive patients with cardiac syndrome X, we prospectively recruited 16 who exhibited(More)
OBJECTIVE Trimetazidine may have beneficial effects on left ventricular (LV) function in patients with systolic heart failure. The authors assessed whether long-term addition of trimetazidine to conventional treatment could improve, along with LV function, resting whole body energy metabolism in patients with chronic systolic heart failure. DESIGN Single(More)
The aim of the study was to assess whether trimetazidine (TMZ) could affect dispersion of atrial depolarization and ventricular repolarization. Corrected QT interval (QTc), QTc dispersion (QTc-d), Tpeak-Tend, and Tpeak-Tend dispersion (Tpeak-Tend-d) were measured in 30 patients with chronic heart failure (CHF) before and 6 months after randomization to(More)
OBJECTIVES Our aim was to assess clinical outcome after transcatheter aortic valve implantation (TAVI) performed with the 2 commercially available valves with 3 delivery approaches selected in a stepwise fashion. BACKGROUND Limited data exist on the results of a comprehensive TAVI program using different valves with transfemoral, transapical, and(More)
OBJECTIVES The aim of this study was to evaluate the incidence, predictors, management, and clinical outcomes in patients with grade III coronary perforation during percutaneous coronary intervention. BACKGROUND Grade III coronary perforation is a rare but recognized complication associated with high morbidity and mortality. METHODS From 24,465 patients(More)
Radioligand binding studies and functional assays on isolated smooth muscle preparations were performed in order to obtain a biochemical and functional characterization of the beta-adrenoceptor (beta-AR) subtypes involved in regulation of the smooth muscle relaxation of the calf's common digital artery. The results indicate that the common digital artery(More)
Alterations of cardiac metabolism can be present in several cardiac syndromes. Heart failure may itself promote metabolic changes such as insulin resistance, in part through neurohumoral activation, and determining an increased utilization of non-carbohydrate substrates for energy production. In fact, fasting blood ketone bodies as well as fat oxidation(More)
Poor long-term outcomes after percutaneous coronary intervention (PCI) in chronic total occlusion (CTO) of saphenous vein grafts (SVGs) have been reported. However, limited data are available evaluating the use of modern techniques in this group. The aim of the present study was to assess the efficacy and long-term outcomes of PCI in SVG CTO with the(More)
