Executive Industry Relevance

Quantitative assessment of bilateral atrial function using CMR feature tracking enables early detection of functional remodeling in paroxysmal atrial fibrillation, supporting mechanistic de-risking and target validation in cardiovascular drug discovery. High-resolution, reproducible strain and strain rate measurements provide predictive confidence for translational biomarker development and portfolio triage. Integrating these non-invasive imaging biomarkers into discovery-stage workflows enhances risk-adjusted decision-making for atrial disease-modifying therapies.
