| Research Abstract |
The purpose of this study was to quantify myocardial strain on the subendocardial and epicardial layers of the left ventricle (LV) using tagged cardiovascular magnetic resonance (CMR) and to investigate the transmural degree of contractile impairment in the chronic ischemic myocardium. In conclusion, analysis of 3T tagged MR can non-invasively quantify the transmural degree of left ventricular deformation and demonstrate predominate impairment of subendocardial strain in the chronic ischemic myocardium at rest.
