Study to examine correlation between predictive value and post PCI value of iFR, RFR and dPR - Correlation between predictive value and post PCI value of iFR, RFR and dPR

The pre-PCI predicted NHPRs had strong correlations with actual post-PCI NHPRs. The agreements be-tween pre-PCI predicted and actual post-PCI NHPRs were 0.02 for iFR, 0.01 for RFR, 0.02 for dPR, respectively.The number and the total length of treated lesions were lower in the NHPR pullback- than in the angiography-guided strategy. Actual post-PCI NHPRs had a poor correlation to the difference between angiography- and NHPR pullback-guided strategies
