DT-CMR Parameters in HCM Patients and Healthy Control Subjects

	HCM Patients (n = 50)	Healthy Control Subjects (n = 30)	p Value
FA	0.49 ± 0.05	0.52 ± 0.03	0.0005
ADC, ×10−3 mm2/s	1.29 ± 0.10	1.26 ± 0.12	0.20
HA gradient, degrees/mm	−7 ± 1	−8 ± 2	0.53
SA,°	5 ± 23	84 ± 31	<0.0001
SNR estimate	10.0 ± 2.5	10.4 ± 2.6	0.53

Values are slice mean ± SD, and for SA, circular mean ± SD. Bold p values are significant.

ADC = apparent diffusion coefficient; DT-CMR = diffusion tensor cardiac magnetic resonance; FA = fractional anisotropy; HA = helix angle; HCM = hypertrophic cardiomyopathy; SA = sheetlet-normal angle in segment of maximum thickness (0º denotes radial orientation of sheetlet populations); SNR = signal-to-noise ratio.
