BACKGROUND Contrast agents can cause a reduction in renal function that may be due to the generation of reactive oxygen species. Conflicting evidence suggests that administration of the antioxidant acetylcysteine prevents this renal impairment. The action of other antioxidant agents has not been investigated. METHODS AND RESULTS We conducted a randomized,(More)

Plasma levels of brain natriuretic peptide (BNP) have been shown to correlate to aortic stenosis severity and are predictive of symptom development and survival. They also predict postoperative outcomes after valve replacement in patients with aortic stenosis. The early evolution of N-terminal-pro-BNP (NT-pro-BNP) levels after 50 aortic balloon(More)
BACKGROUND Although the superiority of low-osmolar over high-osmolar contrast agents in prevention of contrast-induced acute kidney injury (CI-AKI) is generally accepted, the relative nephrotoxicity of iso-osmolar over low-osmolar agents has not yet clearly defined. We examined the incidence of CI-AKI according to the type of contrast agent used in a(More)
BACKGROUND Recent experimental and clinical data suggest that lowering serum lipid levels with statins may prevent or delay the process of restenosis. The purpose of this trial is to determine whether lipid levels relate to restenosis and/or whether statin therapy can prevent or delay the process of restenosis after intracoronary stenting. METHODS One(More)
BACKGROUND Encouraging results with the use of the sirolimus-eluting stent (SES) have been recently presented in several multi-center trials. In the present study, the short- and mid-term clinical outcomes of the SES in everyday clinical practice of interventional cardiology were compared with a strategy using conventional bare metal stents. METHODS In a(More)
