Cardiovascular magnetic resonance imaging assessment of outcomes in acute myocardial infarction

Table 8 Temporal changes in cardiovascular magnetic resonance late microvascular obstruction in acute myocardial infarction

Ref.	Year	n	CMR timepoints	LGE method	Main findings
Carrick et al[74]	2016	30	8 h → 3 d → 10 d → 7 mo	Auto	L-MVO in 20%, peaked early at 8 h and stable at d3. Decreased by d10, absent at 7 mo
Mather et al[18]	2011	48	2 d → 1 wk → 30 d → 3 mo	> 2SD	L-MVO in 60%, peak at d2. Decrease at subsequent points. L-MVO absent at 3 mo
Ganame et al[20]	2011	58	3 d → 4 mo → 12 mo	Manual	L-MVO in 64%. L-MVO absent at 4 mo
Ripa et al[5]	2007	58	2 d → 6 mo	Manual	L-MVO in 42%. L-MVO absent at 6 mo
Hombach et al[6]	2005	110	6 d → 9 mo	Manual	46% had L-MVO (2.8% LV mass, 16% of IS) on acute CMR. L-MVO absent at 6 mo

MVO: Microvascular obstruction; LGE method: SD: Standard deviations; IS: Infarct size; LV: Left ventricle; CMR: Cardiovascular magnetic resonance.
