Ref.	Year	n	CMR times post STEMI	Relative LGE IS reduction	LGE method	Main findings
Carrick et al[74]	2016	30	8 h → 3 d → 10 d → 7 mo	26%	Automated	Significant decrease d3 to d10 (20% ± 13% to 14% ± 10% LV mass). No change at 7 mo
Dall’Armelina et al[21]	2011	30	2 d → 6 mo	22%	> 2SD	IS reduced at times from 27% ± 15% LV mass 24 h post PPCI, to 21% ± 11% at 6 mo
Mather et al[18]	2011	48	2 d → 1 wk → 30 d → 3 mo	37%	> 2SD	27% IS drop between d2 and d7 post PPCI, no change at 3 mo
Ganame et al[20]	2011	58	3 d → 4 mo → 12 mo	45%	Manual	33% decrease IS d3 and 4 mo then no further decrease at 12 mo
Ibrahim et al[9]	2010	17	1 d → 1 wk → 1 mo → 6 mo	37%	Manual	34% reduction in IS from d2 to 1 wk, then no further change at 1 and 6 mo
Engblom et al[7]	2009	22	1 d → 1 wk → 12 mo	40%	Automated	28% reduction in IS between d1 and 1 wk
Ripa et al[5]	2007	58	2 d → 1 mo → 6 mo	30%	Manual	14% % reduction in IS from d2 to 1 mo
Hombach et al[6]	2005	110	6 d → 9 mo	28%	Manual	28% reduction in IS from d6 to 9 mo

LGE method: SD: Standard deviations; Total LGE IS Overest: Relative overestimation of final IS (last timepoint) on acute CMR; CMR: Cardiovascular magnetic resonance; LGE: Late gadolinium enhancement; IS: Infarct size; PPCI: Primary percutaneous coronary intervention.
