Introduction: Fractional flow reserve (FFR) is the reference method in decision making concerning revasularization. The role of FFR measured directly after drug eluting stent (DES) implantation (post-PCI FFR) is less clear in predicting major adverse cardiac events (MACE), furthermore it is not known which clinical parameters affect post-PCI FFR.
Aim: We sought to clarify the correlation between post-PCI FFR and clinical parameters, the relationship between post-PCI FFR and long-term MACE and determine the best post-PCI FFR cut-off in MACE prediction.
Method: We included patients with FFR-guided DES implantation and post-PCI FFR measurement in GOKVI between January 2009 and August 2019. We examined the relationship between post-PCI FFR and gender, age, LAD (vs. non-LAD) localization, indication (acute vs. chronic coronary syndrome), diabetes mellitus, and stent diameter, and the relationship between post-PCI FFR and target vessel-related MACE (cardiovascular mortality (CVD), non-fatal myocardial infarction (MI), recurrent revascularization (TVR)). Optimal diagnostic cut-off was determined by ROC curves.
Results: Post-PCI FFR measurement was performed in 423 coronary arteries of 362 patients. Post-PCI FFR was lower in LAD than in non-LAD localization (0.86 vs. 0.91, p<0.001). Female gender (0.89 vs. 0.87, p<0.001) and greater stent diameter resulted in higher post-PCI FFR (p<0.001), and there was no significant correlation between age, diabetes mellitus, PCI indication category and post-PCI FFR. During a median follow-up of 36 months, 23 CVD, 15 MI, and 31 TVR occurred. Follow-up was complete in 94.5% of patients. There was a significant inverse correlation between post-PCI FFR and MACE (p<0.001). The best post-PCI FFR cut-off for the total patient population, LAD and non-LAD lesions were 0.86 (p=0,0018), 0.83 (p=0,0012), and 0.91 (p=0,0458), respectively.
Conclusion: Post-PCI FFR in the LAD is significantly lower than in other coronaries. Female gender and greater stent diameter resulted in significantly higher post-PCI FFR. There is no significant difference between post-PCI FFR measured in acute vs. chronic coronary syndrome. FFR measured after DES implantation is a significant predictor of MACE-free long-term survival. The best post-PCI FFR cut-off to predict MACE was 0.86 for the whole patient population, 0.83 and 0.91 for LAD and non-LAD lesions.
