Comparison of cardiac biomarker levels in subjects with acute Kawasaki disease (KD), convalescent KD (conv. KD), febrile controls (FC), and healthy controls (HC)

Biomarker Proteins	Acute KD (n=55)	Conv. KD (n= 30)	FC (n=54)	HC (n=50)
NT-proBNP (pg/mL)	319.5 (117.3-651.6)	41.1^* (28.7-66.2)	102.0^* (46.1-197.3)	65.2^*^† (45.0-112.3)
sST2 (ng/mL)	46.1 (22.7-114.8)	12.5^* (9.9-15.3)	28.4^* (19.0-43.1)	7.2^*^† (4.3-9.7)
cTnI (ng/mL)	0.0014 (0.0003-0.0062)	0.0030^* (0.0014-0.0119)	0.0013 (0.0004-0.0056)	0.0008^*^† (0.0007-0.0012)

Values are presented as median (interquartile range).

Significant at p<0.05 compared to acute KD by Mann Whitney U test and Wilcoxon signed rank test for paired acute and convalescent KD.

^†

NT-proBNP, sST2, and cTnI levels in acute KD subjects were compared with n=20, n=30, and n=30 age-similar HC, respectively.

NT-proBNP = N-terminal pro-B-type natriuretic peptide; sST2 = soluble ST2; cTnI = cardiac troponin I.
