Strain analysis by speckle-tracking echocardiography in apical 4 chamber view

	Normal ECHO (N = 40)	Intervention (N = 11)	P value
RV pLS	−20.0 (3.5)	−17.5 (4.3)	0.06
RV pLSR	−0.98 (0.17)	−0.83 (0.20)	0.02
RV early diastolic SR	1.05 (0.20)	0.85 (0.26)	0.01
LV pLS	−25.1 (4.6)	−23.8 (4.0)	0.39
LV pLSR	−1.28 (0.24)	−1.21 (0.22)	0.35
LV early diastolic SR	1.31 (0.30)	1.23 (0.31)	0.44

Expressed as mean (standard deviation).

ECHO, echocardiography; LV, left ventricle; pLS, peak longitudinal strain in A4C; RV, right ventricle; SR, strain rate.
