Echocardiographic Evaluation of Systolic and Diastolic Function: A Preoperative Study of Correlation with Serum NT-proBNP

A correlation was found between plasma levels of NT-proBNP and speckle tracking ultrasound strain measurements by an easily employed method applicable in the anesthesia and preoperative settings. In addition, the well-established marker of diastolic function, E/E′, correlated well with NT-proBNP, whereas the E/A ratio failed to show any association.
