	Patients (n = 21)	Controls (n = 20)
Strian	(mean ± SD)	(mean ± SD)	p-value
SLSC peak G (%)	–16.45 ± 10.74	–16.09 ± 9.85	0.77
SLSC peak S (%)	–15.22 ± 11.57	–14.64 ± 11.38	0.67
SLSC peak P (%)	2.60 ± 5.09	2.75 ± 5.46	0.82
SLSC (ES) (%)	–14.20 ± 12.41	–13.71 ± 12.89	0.74
STSR (ES) (%)	41.04 ± 18.29	44.92 ± 17.47	0.72
DTDR (ES) (mm)	5.145 ± 2.54	5.01 ± 2.48	0.65
ROT (ES) (°)	–4.49 ± 4.53	–2.84 ± 5.06	0.004

SLSC peak G: the most negative peak circumferential strain, SLSC peak S: negative systolic peak circumferential strain, SLSC peak P: positive systolic peak circumferential strain, SLSC (ES): end-systolic circumferential strain, DTDR (ES): end-systolic radial displacement, ROT (ES): end-systolic rotation.
