Figure 2: Relationship between pre-operative Tei Index and post-operative fractional area change [Figure 2a] and post-operative ejection fraction (EF) [Figure 2b] in the total study population (n=104). Relationship between pre-operative Tei Index and post-operative fractional area change and to ejection fraction in group I (EF≤55, Figure 2c and 2d; n=36). Relationship between pre-operative Tei Index and post-operative fractional area change and post-operative ejection fraction in group II (EF≤55, Figure 2e and 2f; n=68). Inserted are the linear fit lines with the upper and lower 95% confidence limits. FAC- Fractional area change; EF- Ejection fraction
