Correlates of peak-exercise BNP level in the whole cohort (n=211)

Ln peak-exercise BNP	Individual		Multivariate model*
Ln peak-exercise BNP	β coeff.±SE	p Value	β coeff.±SE	p Value
Resting mean transvalvular gradient, mm Hg	0.25±0.004	0.0003	0.16±0.005	0.03
Resting indexed left atrial area, cm²/m²	0.23±0.02	0.001	0.15±0.02	0.04
Resting valvulo-arterial impedance, mm Hg/mL m²	0.25±0.06	0.0002	0.20±0.07	0.009

*Multivariate model included age, gender, peak-exercise workload, and exercise-induced increase in heart rate, mean transvalvular gradient and valvulo-arterial impedance. β coeff. is the standardised regression coefficient±SE.
BNP, B-type natriuretic peptide.
