A patient with a mid-LAD infarct receiving early intravenous metoprolol. a, bSSFP end-diastolic images with endo- and epi-cardial contours. The LV volumes remained stable and the LVEF increased at 6 months after STEMI. b, T2-STIR images showing the presence of edema (white arrows) at 1-week after STEMI. c, LGE images showing the presence of acute ischemic injury/infarct scar (black arrows) at 1 week/6-months after STEMI. d, end-systolic bSSFP images with feature-tracking circumferential LV strain overlay. At 6 months the infarct zone circumferential strain improved while the remote zone strain remained stable

The same abbreviations were used as in Fig. 3
