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.

Non invasive assessment of left ventricular filling pressure and remodeling after acute myocardial infarction.
Left ventricular (LV) dilation after acute myocardial infarction (AMI) is an important determinant of prognosis. The ratio of early mitral inflow velocity (E) and peak early diastolic annular velocity (e') provides the best single index for noninvasive detection of acute elevation of LV filling pressure. ⋯ The E/e' ratio is a useful predictor of LV remodeling after AMI, indicating patients with increased cardiovascular risk.
