Comparison of segment viability in three groups divided by left ventricular ejection fraction
| Characteristics of segments | LVEF ≤20% (23 patients) | LVEF 21–30% (54 patients) | LVEF >30% (27 patients) |
| Dysfunctional | 14.1 (2.0) | 10.9 (4.5)† | 9.7 (3.9) |
| Viable by Tc-99m | 6.4 (3.7) | 4.6 (3.8)* | 3.8 (3.2) |
| Viable by Tc-99m + FDG | 7.2 (4.0) | 5.1 (4.1)* | 4.2 (3.2) |
*p<0.05; †p<0.005 v LVEF ≤20%.
FDG, fluorodeoxyglucose; LVEF, left ventricular ejection fraction.
