  "abstract": "BACKGROUND: Intracoronary imaging-derived physiologic indices enable vessel-level assessment of coronary flow impairment by integrating obstructive plaque burden. However, accurately evaluating hyperemic flow remains challenging due to the difficulty of simultaneously incorporating both vascular geometry and plaque composition. METHODS AND RESULTS: values correlated strongly with wire-based ∆FFR (R=0.932, P<0.001), achieving an accuracy of 0.952 for detecting physiologically significant lesions and an area under the curve of 0.953 in the ROC analysis. The model accurately localized segmental pressure gradients, effectively distinguishing focal from diffuse disease patterns. CONCLUSIONS: This novel deep learning-based algorithm enabled lesion-specific, pressure wire-free physiologic assessment from a single OCT pullback. By integrating anatomical and compositional data, it supported improved diagnostic accuracy and personalized treatment for coronary artery disease.",
