Contractile dysfunction following ST-segment elevation myocardial infarction (STEMI) predicts prognosis. CMRmeasured tagging is the gold standard technique for myocardial strain assessment. Strain offers greater accuracy in detecting dysfunctional myocardium than ejection fraction and visual measures of regional function. Tagging however requires acquisition of additional sequences and time-consuming post-processing. FT tracks features of interest along contour lines on routinely acquired steady-state free-precession (SSFP) cine images. There are no published strain data using FT in acute STEMI. This study aimed to assess the feasibility of FT measured global and segmental circumferential (Ecc) and longitudinal (Ell) strain assessment post acute STEMI and compare values to those obtained with tagging.
