Initial echocardiographic parameters (at time of diagnosis; total n = 19) in patients with a final LVEF <40% (poor echocardiographic outcome) compared to those with a final LVEF >40%.

Parameter at diagnosis	Patients with a final LVEF <40% (n = 5) median (IQR)	Patients with a final LVEF ≥40% (n = 14) median (IQR)	P value
MA E′ave (cm/s)	11.5 (8.0–12.0)	7.5 (6.5–9.5)	0.221
MA E/E′	10.0 (9.6–12.9)	13.3 (10.3–16.2)	0.267
LVID (cm)	5.6 (5.4–5.7)	5.2 (4.5–5.5)	0.343
LVEF (%)	34.0 (30–35)	38 (35–50)	0.046
GLS (%)	−9.5 (−13 to −9)	−13.5 (−16 to −11)	0.095
Wall motion score	2.06 (1.88–2.13)	1.81 (1.5–2.19)	0.506

E′ave, early diastolic mitral annular velocity, average of lateral and septal measurement; E/E′, ratio of mitral peak velocity of early filling (E) to early diastolic mitral annular velocity (E′); GLS, global longitudinal strain; IQR, interquartile range; LVEF, left ventricular ejection fraction; LVID, left ventricular internal diameter; MA, mitral annular.
