✦ Synopsis

Global longitudinal and circumferential strain was assessed by echo in 15 patients after acute MI. MRI parameters including ventricular volumes, scar, and area at risk were assessed 3+/-2 days post STEMI and at 30 day follow up. Echo strain measures correlated most strongly with LVEF (r=0.81 and 0.88 longitudinal ad circumferential strain, p<0.0001) and infarct size (r=-0.68 and r=-0.69, p<0.001). There were moderate correlations between longitudinal strain and change in LVEDV (r=-0.61, p<0.05).

The purpose of this study was to investigate the relationship between the extent of hyperenhancement and left ventricle maximal wall thickness (mWT) detected by LGE CMR and clinical events of nonsustained ventricular tachycardia (NSVT), implantation of cardioverter defibrillator (ICD) or diastolic h
