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.
