No significant differences between EHM and control groups were detected by analyzing parameters of global function as well as their changes over time: (A) ejection fraction (EF), (B) change in EF, (C) scar size (percentile of LV mass), (D) change in scar size, (E) global strain, and (F) change in global strain. EHM: engineered heart muscle treated group. Ecc: negative peak of circumferential strain.
