We conducted a systematic review and meta-analysis to quantify the association between abnormal FFR-CT and major adverse cardiovascular events (MACE), updating the 2022 meta-analysis by N\u00f8rgaard\n                      <jats:italic>et al<\/jats:italic>\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      We searched PubMed, Embase and Scopus through December 2025 for studies comparing outcomes in patients with suspected or known coronary artery disease with FFR-CT \u22640.80 versus &gt;0.80 (PROSPERO:\n                      <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/www.crd.york.ac.uk\/PROSPERO\/view\/CRD420261276897\">CRD420261276897<\/jats:ext-link>\n                      ). Random-effects meta-analysis with Hartung-Knapp-Sidik-Jonkman adjustment was performed. Subgroup analyses examined FFR-CT technology, geography and follow-up duration.

Follow-up ranged from 12 to 120 months. Patients with FFR-CT \u22640.80 had significantly higher MACE risk (HR 3.94; 95%\u2009CI 2.92 to 5.31; p&lt;0.0001) with substantial heterogeneity (I\u00b2=79.9%). However, restricting to hard endpoints (death\/myocardial infarction; k=6) yielded HR 3.28 (95% CI 2.25 to 4.79) with zero heterogeneity (I\u00b2=0%). No significant differences emerged across FFR-CT technologies (p=0.812), including HeartFlow, machine learning and deep learning algorithms. Trim-and-fill analysis suggested possible publication bias, with adjusted HR 2.35.
