CONTEXT Perioperative red blood cell transfusion is commonly used to address anemia, an independent risk factor for morbidity and mortality after cardiac operations; however, evidence regarding optimal blood transfusion practice in patients undergoing cardiac surgery is lacking. OBJECTIVE To define whether a restrictive perioperative red blood cell(More)
OBJECTIVES The purpose of this pilot study was to evaluate the feasibility and safety of transcatheter aortic valve implantation (TAVI) without balloon pre-dilation. BACKGROUND Balloon pre-dilation of the stenosed aortic valve is currently believed to be a necessary step for valve preparation before device placement in patients undergoing TAVI and,(More)
BACKGROUND Several studies have indicated that a restrictive erythrocyte transfusion strategy is as safe as a liberal one in critically ill patients, but there is no clear evidence to support the superiority of any perioperative transfusion strategy in patients with cancer. METHODS In a randomized, controlled, parallel-group, double-blind (patients and(More)
BACKGROUND The natural history and consequences of severe H1N1 influenza infection among cancer patients are not yet fully characterized. We describe eight cases of H1N1 infection in cancer patients admitted to the intensive care unit of a referral cancer center. PATIENTS AND METHODS Clinical data from all patients admitted with acute respiratory failure(More)
INTRODUCTION Diabetes mellitus is a major cause of coronary artery disease (CAD). Despite improvement in the management of patients with stable CAD, diabetes remains a major cause of increased morbidity and mortality. There is no conclusive evidence that either modality is better than medical therapy alone for the treatment of stable multivessel CAD in(More)
OBJECTIVE To ascertain incidence and predictors of new permanent pacemaker (PPM) following transcatheter aortic valve implantation (TAVI) with the self-expanding aortic bioprosthesis. BACKGROUND TAVI with the Medtronic Corevalve (MCV) Revalving System (Medtronic, Minneapolis, MN) has been associated with important post-procedural conduction abnormalities(More)
BACKGROUND The importance of complete revascularization remains unclear and contradictory. This current investigation compares the effect of complete revascularization on 10-year survival of patients with stable multivessel coronary artery disease (CAD) who were randomly assigned to percutaneous coronary intervention (PCI) or coronary artery bypass graft(More)
Cardiovascular diseases represent the greatest burden of morbidity and mortality for the health system and cardiac surgery has an important impact on their resolutivity. The association and correlation of patients' demographic and clinical relevant information with the resources required for each stratum represent the possibility to adapt, improve and(More)
BACKGROUND Heart surgery has developed with increasing patient complexity. OBJECTIVE To assess the use of resources and real costs stratified by risk factors of patients submitted to surgical cardiac procedures and to compare them with the values reimbursed by the Brazilian Unified Health System (SUS). METHOD All cardiac surgery procedures performed(More)
BACKGROUND Previous studies have demonstrated that leukocytosis and hyperglycemia verified at the admission of patients with acute myocardial infarction (AMI) are associated with intrahospital mortality. However, little is known on the long-term impact of these markers. OBJECTIVE To evaluate the short-and long-term influence of the levels of glucose and(More)
