Abstract
The AI-CVD initiative aims to extract actionable insights from coronary artery calcium (CAC) scans beyond the traditional CAC score. Although AI-derived cardiac chamber volumes predict atrial fibrillation (AF) and stroke, the long-term prognostic value of chamber ratios is less established. We evaluated the predictive value of AI-derived left atrial volume index and related chamber ratios (left atrial [LA]/right atrial [RA], LA/left ventricular) from routine CAC scans for incident AF and stroke, and their incremental value beyond established risk scores.
