Parameter	Baseline	95% CI		Acute MI	95% CI		p value	Chronic MI	95% CI		p value
Parameter	Baseline	Upper	Lower	Acute MI	Upper	Lower	p value	Chronic MI	Upper	Lower	p value
Endocardial ACS (%)	− 37.5	− 31.2	− 49.4	− 17.7	− 16.8	− 27	0.004	− 19.1	− 12.3	− 26.3	0.002*
Endocardial GCS (%)	− 34.9	− 30.5	− 28.4	− 23.8	− 21.1	− 26.1	0.002*	− 27.7	− 17.8	− 31.6	0.006

LVEF (%)	57	52	62	45	40	50	0.002*	50	46	54	0.019
LVESVi (ml/m²)	35.9	26.8	49.1	52.1	45.3	60.3	0.045	50	37.4	63.3	0.127

CI = Confidence interval; ACS = Apical circumferential strain; GCS = Global circumferential strain; GLS = Global longitudinal strain; LVESVi = Left ventricular end-systolic volume index; p values are for differences compared to baseline results. *denotes changes significant to p < 0.0024.
