Biomarkers in subtypes of aortic stenosis

Biomarker	Mean AVG ≥40 mm Hg (n=46)	LVEF <50% and mean AVG <40 mm Hg (n=10)	LVEF ≥50% and mean AVG <40 mm Hg (n=17)	P values
NT-proBNP	4920 (1677.5–15 975)	15 9755 (11 493.75–15 975)	2080 (898–3410)	<0.001
vWF	127 (92.5–171.75)	185.5 (145.5–262)	117 (80–172)	0.055
Fetuin-A	594.5 (499.25–667)	603 (501.75–855.25)	781 (656–872)	0.01
AS risk score	6.24±1.58	6.46±1.21	5.36±1.29	0.08

Values are mean±SD, median (IQR).

AS, aortic stenosis; AVG, aortic valve gradient; LVEF, ejection fraction; NT-proBNP, N-terminal pro-B-type natriuretic peptide; vWF, von Willebrand factor.
