Cardiovascular magnetic resonance imaging assessment of outcomes in acute myocardial infarction

Table 11 Cardiovascular magnetic resonance studies illustrating the importance of intramyocardial haemorrhage on left ventricular function and remodelling in acute myocardial infarction

Ref.	Year	n	IMH CMR method	Main findings	CMR time post MI	Mean/median F/U CMR
Carrick et al[74]	2016	245	T2*	IMH strongest IP for LVR. IMH associated with lower LVEF and greater volumes	3 d	7 mo
Kidambi et al[115]	2013	39	T2w-TSE and T2*	IMH associated with attenuation of follow-up infarct strain	3 d	3 mo
Husser et al[33]	2012	304	T2w-TSE	IMH strongest IP for LVR in model with LVEF, IS, LV vol, L-MVO	6 d	189 d
Mather et al[131]	2011	48	T2w-TSE and T2*	IMH strongest IP of LVR in model with IS, LVEF, LVESV, E-MVO, MSI	2 d	3 mo
Beek et al[24]	2010	45	T2w-TSE	IMH was a univariate predictor of LVEF. However no prognostic significance beyond baseline LVEF and MVO in predicting final LVEF	5 d	4 mo
Bekkers et al[121]	2010	90	T2w-TSE	Acute MSI and LVEF increase at follow-up lowest if IMH present. But IMH no prognostic significance beyond MVO in predicting LVEF	5 d	103 d
O’Regan et al[126]	2010	50	T2*	IMH presence univariate predictor of LVEF and LV volumes. However only IS independently predicted LVEF	3 d	N/A
Ganame et al[25]	2009	98	T2w-TSE	IMH extent strongest IP of LVR in model with IS, E-MVO, Troponin-I, AAR, TTR, IS	2 d	4 mo

IS: Infarct size; IP: Independent predictor; LVR: Left ventricular remodelling; MVO: Microvascular obstruction; LVEF: Left ventricular ejection fraction; LVESVI: Left-ventricular end systolic volume index; T2w-TSE: T2-weighted turbo spin-echo; AAR: Area at risk; MSI: Myocardial salvage index; N/A: Not applicable.
