Few data are available on diastolic function in patients with aortic stenosis (AOS) with indication of surgical treatment. A potential correlation between biomarkers and diastolic function has not been established. ⋯ AOS patients' ventricular diastolic function improved after AVR. The biomarker NT-proBNP might be a useful biomarker of diastolic function in these patients, before and after AVR. NT-proBNP values show a positive correlation with echocardiographic variables that determine diastolic dysfunction, and is a good marker for the characterization of this dysfunction in AOS patients.
