Cardiovascular magnetic resonance imaging assessment of outcomes in acute myocardial infarction

Table 13 Cardiovascular magnetic resonance studies showing the importance of myocardial salvage index on left ventricular function and remodelling in acute myocardial infarction

Ref.	Year	n	AAR, IS method	Main findings	CMR timepoint post STEMI	Follow-up
Mather et al[131]	2011	48	> 2SD STIR, > 2SD LGE	MSI was IP for LVR (OR 0.95) in model including LV volumes, LVEF, IS, IMH, MVO	2 d	3 mo
Monmeneu et al[91]	2012	118	> 2SD STIR, > 2SD LGE	MSI univariate predictor of LVR and final LVEF. However not IP of LVR in model with LVESVI, IS, no. transmural segs	6 d	6 mo
Masci et al[14]	2011	260	> 2SD STIR, > 5SD LGE	MSI strong univariate predictor of LVR and final LVEF. However not IP in model including IS, MVO	1 wk	4 mo
Masci et al[26]	2010	137	> 2SD STIR, > 5SD LGE	MSI strongest IP for LVR However IS and MSI (r = -0.72) and IS and AAR (r = 0.85) correlated	1 wk	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; STIR: T2-weighted short-tau inversion-recovery; LGE: Late gadolinium enhancement.
