NT-proBNP Levels in TS Study Participants Stratified by Aortic Dilation

	Dilated^‡ Ascending Aorta (n = 42)	Non-Dilated Ascending Aorta (n = 72)	P
Age, y	44.6 ± 12.0	33.1 ± 10.5	< 0.001
BSA, m²	1.44 ± 0.18	1.62 ± 0.19	< 0.001
Systolic BP, mm Hg	121.4 ± 14.5	120.2 ± 10.3	0.582^*
AAD, mm	31.7 ± 4.5	24.9 ± 3.4	< 0.001^*
AAD/BSA mm/m²	22.2 ± 2.3	15.4 ± 2.0	< 0.001^*
DAD, mm	19.2 ± 2.9	17.6 ± 2.7	0.003^*
DAD/BSA mm/m²	13.4 ± 2.2	10.9 ± 1.8	< 0.001^*
NT-proBNP, pg/mL	112.4 ± 75.7	74.2 ± 49.0	0.0014^†

Values are means ± SD. Mean values compared by ANOVA or *ANCOVA with age as a covariate or ^†ANCOVA with age and BSA as covariates.
