Magnetic resonance imaging of the transplanted pediatric heart as a potential predictor of rejection

Table 1 Patient characteristics

	Controls	No rejection (0R/1R)	Rejection (2R)
Number	14	25	5
Female (%)	8 (57)	10 (40)	1 (20)
Days post-transplant	-	702 (78, 1797)	160 (12, 800)
Age at CMR (yr)	12.8 (9.2, 15.3)	13.6 (2.2, 17)	7.7 (1.6, 17.5)
HR	71 (57, 84)	96b (82, 126)	108d (101, 130)
BNP	9.2 (5, 12.9)	38.7f (5, 81.6)	59.9g (14.9, 202)

Data shown as number (percentage) or median (10^th, 90^th percentiles). Significantly different compared to controls,

^bP = 5.76E-05,

^dP = 0.005,

^fP = 0.005,

^gP = 0.03. There were no significant differences between the transplanted rejection groups. HR: Heart rate in beats per minute; BNP: Brain natriuretic peptide in ng/L; CMR: Cardiac magnetic resonance imaging.
