The prognostic value of predicting future cardiovascular events is less clear, as studies are limited by small populations, variable measurement points, composite outcomes, and short follow-up.<\/jats:p>\n <\/jats:sec>\n \n OBJECTIVES:<\/jats:title>\n A nationwide cohort of coronary computed tomography angiography with 3-year follow-up was used to examine the association between FFR-CT measurements and future cardiovascular events.<\/jats:p>\n <\/jats:sec>\n \n METHODS:<\/jats:title>\n Patients receiving coronary computed tomography angiography and clinically indicated FFR-CT analysis (HeartFlow) for stable coronary artery disease between 2017 and 2020 at 27 sites across England were included. Lowest per-patient stenosis-specific and distal vessel FFR-CT measurements were related to individual outcomes of myocardial infarction (MI), cardiovascular mortality, all-cause mortality, and revascularization. FFR-CT measurements were divided into subgroups to investigate for a gradient of risk: normal FFR-CT (>0.8), borderline (0.71\u20130.8), reduced (0.51\u20130.7), and severely reduced (\u22640.5).<\/jats:p>\n <\/jats:sec>\n \n RESULTS:<\/jats:title>\n \n In total, 7836 patients aged 63 (56.0\u201371.0), 37.4% women, underwent FFR-CT analysis. Stenosis-specific FFR-CT was associated with future MI (hazard ratio [HR], 2.08\u20135.73;\n P<\/jats:italic>\n <0.001), cardiovascular death (HR, 1.51\u20133.40;\n P<\/jats:italic>\n <0.001), all-cause death (HR, 1.01\u20131.58;\n P<\/jats:italic>\n =0.01), and revascularization (HR, 4.79\u201324.48;\n P<\/jats:italic>\n <0.001), with lower FFR-CT values associated with incrementally greater risk. After adjusting for cardiovascular risk factors and coronary stenosis severity (Coronary Artery Disease Reporting and Data System), stenosis-specific FFR-CT\u22640.7 was associated with MI (adjusted HR, 2.94\u20133.39;\n P<\/jats:italic>\n <0.001), \u22640.5 with cardiovascular death (adjusted HR, 2.92;\n P<\/jats:italic>\n =0.02), all-cause death (adjusted HR, 1.49;\n P<\/jats:italic>\n =0.045), and \u22640.8 with revascularization (adjusted HR, 3.02\u20139.42;\n P<\/jats:italic>\n <0.001). The addition of FFR-CT improved discrimination for MI or cardiovascular death compared with a risk factor and stenosis severity model (C index, 0.783; \u2206C index, 0.012;\n P<\/jats:italic>\n <0.001). An FFR-CT value of 0.67 defined the optimal cutoff for risk of future cardiovascular events. Distal-vessel FFR-CT was associated with outcomes similar to stenosis-specific FFR-CT. Stenosis-specific and distal-vessel FFR-CT discordance was common (36.4%), but when stenosis-specific FFR-CT was normal, event rates were low (1.5% at 3 years for MI or cardiovascular death).\n <\/jats:p>\n <\/jats:sec>\n \n CONCLUSIONS:<\/jats:title>\n FFR-CT is associated with the individual outcomes of MI, cardiovascular death, and all-cause death independent of risk factors and stenosis severity, with lower FFR-CT values associated with worse outcomes. Reduced and severely reduced FFR-CT have the strongest association with future cardiovascular events, with a value of 0.67 defining the optimal risk threshold.<\/jats:p>\n
