Prognostic Value of Coronary Computed Tomography Angiography-Derived Fractional Flow Reserve From a Large Nationwide Cohort.

Coronary computed tomography angiography-derived fractional flow reserve (FFR-CT) predicts future cardiovascular events with significant accuracy, especially below a threshold of 0.67, in a large nationwide cohort.

• Why it matters: Accurate prediction of future cardiovascular events remains challenging, limiting the ability to tailor preventive strategies effectively. Understanding FFR-CT's prognostic value could improve risk stratification in stable coronary artery disease.
• What they did: The study analyzed 7,836 patients across England who underwent FFR-CT analysis, relating FFR-CT measurements to outcomes like myocardial infarction, death, and revascularization over three years, with risk subgroups defined by FFR-CT thresholds.
• The result: Lower FFR-CT values were strongly associated with increased risks of adverse events, and incorporating FFR-CT improved prediction models, enabling better identification of high-risk patients for targeted interventions.
