Myocardium at risk without necrosis. T2 maps and late gadolinium enhancement (LGE) images are shown in a mid short-axis plane from representative sham and NSTE-ACS model animals. In the sham, mild T2 elevation was observed in the affected area (solid arrow) compared to the remote region (dotted arrow). In the model, creation of left circumflex coronary artery stenosis and tachycardic pacing produced significantly more pronounced myocardial T2 elevation in the affected area. LGE demonstrated no myocardial enhancement.
