Comparative StudyComparison of diagnostic criteria for acute kidney injury in cardiac surgery.
There is considerable controversy regarding the diagnosis of Acute Kidney Injury (AKI), and there are over 30 different definitions. ⋯ The incidence and risk factors for AKI after cardiac surgery vary significantly according to the diagnostic criteria used. In our analysis, AKI the KDIGO criterion was superior to AKIN and RIFLE with regard its prognostic power.

Relationship between left atrial volume and diastolic dysfunction in 500 Brazilian patients.
Left atrial volume index (LAVI) increase has been associated to left ventricle (LV) diastolic dysfunction (DD), a marker of cardiovascular events (atrial fibrillation, stroke, heart failure, death). ⋯ DD contributes to left atrial remodeling. LAVI increases as an expression of DD severity and is independently associated to age, left ventricle hypertrophy, systolic dysfunction and increased LV filling pressures.

Prognostic value of perioperative N-terminal pro-B-type natriuretic peptide in noncardiac surgery.
Preoperative NT-proBNP has been shown to predict adverse cardiac outcomes, although recent studies suggested that postoperative NT-proBNP determination could provide additional information in patients submitted to noncardiac surgery. ⋯ NT-proBNP is a powerful short-term marker of perioperative cardiovascular events in high risk patients. Postoperative levels were less informative than preoperative levels. A single preoperative NT-proBNP measurement should be considered in the preoperative risk assessment.
