OBJECTIVES The aim of this research was to assess the incidence, clinical predictors, and outcome of contrast-induced nephropathy (CIN) after primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI). BACKGROUND Contrast-induced nephropathy is associated with significant morbidity and mortality after PCI. Patients undergoing(More)
BACKGROUND Patients with acute myocardial infarction undergoing primary angioplasty are at high risk for contrast-medium-induced nephropathy because of hemodynamic instability, the need for a high volume of contrast medium, and the lack of effective prophylaxis. We investigated the antioxidant N-acetylcysteine for the prevention of contrast-medium-induced(More)
BACKGROUND Contrast-induced nephropathy (CIN) frequently occurs in patients with acute ST-segment elevation myocardial infarction (STEMI) who are undergoing primary percutaneous coronary intervention, and CIN is associated with a more complicated clinical course and increased mortality. OBJECTIVE To investigate the association between absolute and weight-(More)
BACKGROUND Nephropathy induced by exposure to radiocontrast agents, a possible complication of percutaneous coronary interventions, is associated with significant in-hospital and long-term morbidity and mortality. Patients with preexisting renal failure are at particularly high risk. We investigated the role of hemofiltration, as compared with(More)
Acute kidney injury (AKI) occurs frequently in patients with acute coronary syndromes (ACS) and is associated with adverse short- and long-term outcomes. To date, however, no standardized definition of AKI has been used for patients with ACS. As a result, information on its true incidence and the clinical and prognostic relevance according to the severity(More)
OBJECTIVES The goal of this study was to investigate the hemodynamic and circulatory adjustments to extracorporeal ultrafiltration (UF) in refractory congestive heart failure (rCHF). BACKGROUND In rCHF, UF allows clinical improvement and restores diuretic efficacy. However, in the course of a UF session, patients are exposed to rapid variations of body(More)
PURPOSE Contrast-induced nephropathy is a complication of contrast medium administration during diagnostic and interventional procedures, with important prognostic relevance. Patients with chronic kidney disease have a higher risk for contrast-induced nephropathy and poorer outcome. In patients with chronic kidney disease, hemofiltration reduces(More)
BACKGROUND Risk stratification of patients with ST-elevation myocardial infarction (STEMI) undergoing primary angioplasty is important in order to predict outcomes and to delineate targeted therapeutic strategies. Although the prognostic implications of reduced left ventricular ejection fraction (LVEF) and creatinine clearance (CrCl) have been recognized,(More)
BACKGROUND Acute hyperglycemia and contrast-induced nephropathy (CIN) are frequently observed in ST-elevation acute myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI), and both are associated with an increased mortality rate. We investigated the possible association between acute hyperglycemia and CIN in(More)
We investigated the relationship between plasma renin activity (PRA) and serum ([sNa(+)]) and urinary ([uNa(+)]) sodium concentrations in 124 congestive heart failure (CHF) patients (II-IV NYHA class) and 20 healthy subjects. According to PRA (> or <3 ng ml(-1) h(-1)) and [sNa(+)] (> or <135 mEq l(-1)), patients were classified as Group A (normal PRA and(More)
