This study also highlights another important observation that average GLS value may not truly reflect the early dysfunction seen in regional strain.[ 7 ] As the classic GLS strain value noted in these studies was cumulative data of all segments, a closer observation showed that there may be significant discrepancies in regional strain value between each segment (i.e. overall regional strain of −18% with −30% in apical septal segment but −11.3% in basal and mid inferoseptal segments).
