Quantitative flow ratio (QFR) is shown to be correlated with FFR before PCI. In this observational study we sought to evaluate the correlation and relative prognostic value of post-PCI QFR compared with post-PCI FFR.Methods and Results We analyzed the outcome of all patients who underwent FFR-guided PCI with post-PCI FFR measurement. Post-PCI QFR was calculated offline, blinded to the value of post-PCI FFR and the clinical outcome. The primary end point was target-vessel failure (TVF) defined as the composite of cardiovascular death, target-vessel-related nonfatal myocardial infarction, and target-vessel repeat revascularization. The secondary end point was the composite of cardiovascular death and myocardial infarction. Median follow-up was 50 months. QFR calculation was unsuccessful in 15.6% of the vessels; thus, 422 vessels of 365 patients were included in the analysis. Post-PCI QFR systematically overestimated post-PCI FFR with a mean bias of +0.052, and their correlation was poor (Pearson's r=0.424). Post-PCI FFR was an independent predictor of TVF and cardiovascular death/myocardial infarction. Post-PCI QFR was associated with TVF, but was not an independent predictor of either TVF or cardiovascular death/myocardial infarction. The optimal cutoff of post-PCI FFR to predict TVF was 0.83, whereas no optimal cutoff of post-PCI QFR could be found.Conclusions Post-PCI QFR has a poor correlation with and overestimates post-PCI FFR. Whereas post-PCI FFR is an independent predictor of clinical outcome, post-PCI QFR is not. true true 2025 true true true false true false GOLD 2026-08-07 false http://jaha.ahajournals.org 2 0 2 1 1 2 2 2 2 2 2 1 1 1 1 0 2 1 2 1 0 6 6 Folyóiratcikk Journal Article 24 2 Könyvrészlet Chapter in Book 25 0 Könyv Book 23 0 Egyéb konferenciaközlemény Conference paper 31 0 Egyéb konferenciakötet Conference proceedings 32 0 Oltalmi formák Protection forms 26 0 Disszertáció Thesis 28 0 Egyéb Miscellaneous 29 0 Alkotás Achievement 22 0 Kutatási adat Research data 33 0 Folyóiratcikk Journal Article 24 0 0 0 Könyvrészlet Chapter in Book 25 0 0 0 Könyv Book 23 0 0 0 Egyéb konferenciaközlemény Conference paper 31 0 0 0 Egyéb konferenciakötet Conference proceedings 32 0 0 0 Oltalmi formák Protection forms 26 0 0 0 Disszertáció Thesis 28 0 0 0 Egyéb Miscellaneous 29 0 0 0 Alkotás Achievement 22 0 0 0 Kutatási adat Research data 33 0 0 0 2025 0 2 1 2 1 D1 false false false false 2025-04-24T08:08:01.090+0000 Biomatika és Alkalmazott Mesterséges Intelligen...
