- •
To identify LV segments ± FFR ≤ 0.80, the area under ROC curve was 0.58 for PSI.
- •
The area under ROC curve was 0.57 for the time interval between AVC and regional PLS.
- •
PSI enabled the identification of LV segments with FFR ≤ 0.80 with thresholds of 12%.
- •
Time interval between AVC and PLS identified LV segments with FFR ≤ 0.80 with 88 ms.
- •
But both areas under ROC curves were not statistically significant.
