The main findings of the present study are as follows: (1) global and segmental strains improved
over time, and GCS showed a significant treatment effect of successful CTO-PCI; (2) GCS and GLS determined by CMR-FT were
strongly correlated with LVEF.

between baseline and follow-up based on per-patient subgroup analysis.
In the subgroup per-patient analysis, the global peak systolic radial
strain (GRS), global circumferential strain (GCS), and global longitudinal
strain (GLS) of the viable (SIE < 50%) and nonviable (SIE ≥ 50%) groups were
not significantly improved after successful CTO-PCI in 1-year follow-up.
