| Abstract | Adverse left ventricular (LV) remodeling with persistent and worsening LV dysfunction after acute myocardial infarction (AMI) is strongly associated with long-term cardiovascular morbidity and mortality.1 Hence, identification of patients with low likelihood of LV contractile recovery despite successful reperfusion therapy represents an important issue in clinical cardiology, with significant implications for patient management. These considerations have stimulated research into new imaging biomarkers, which provide quantitative and objective estimation of post-AMI myocardial damage and potentially identify patients at short- and long-term clinical risk.1,2 See Article by Khan et al In the past 2 decades, cardiac magnetic resonance (CMR) with late gadolinium enhancement (LGE) imaging has emerged as a powerful clinical tool in AMI, providing diagnostic and prognostic information, which are incremental and superior to those obtained using other imaging modalities.1,2 Numerous studies have demonstrated the usefulness of CMR viability indices in predicting functional improvement post AMI. It has been known for some time that the extent of segmental LGE, especially if measured after 7 days post MI, is a key determinant of recovery of myocardial wall thickening and global LV systolic function.3–5 Similarly, the presence of microvascular obstruction on early gadolinium enhancement or LGE imaging and the presence of intramyocardial hemorrhage on T2-weighted short-TI inversion recovery imaging have been linked to poor regional and global functional recovery.6–8 Myocardial deformation imaging techniques, which are able to discriminate between active and passive myocardial contraction in the longitudinal, circumferential, and radial direction, have also been demonstrated of value for … |
