In this presentation, Dr. Matthew Budoff reveals preliminary results from Heartflow’s AI-guided quantitative analysis of the Keto-CTA study. The data focus on coronary plaque progression in participants adhering to a ketogenic diet who experienced a significant rise in LDL cholesterol. Budoff compares the Heartflow data to previously released analyses, discussing patterns of regression, progression, and distribution across key subgroups. This early analysis supports the plausibility and biological consistency expected in longitudinal CCTA imaging, particularly among those with low baseline plaque burden.

Note: Heartflow was unable to process 5 of the 200 scans due to technical limitations. These participants are excluded from all quantitative analyses in this presentation to ensure consistent comparison across datasets.
