Coronary artery disease (CAD) remains the leading cause of cardiovascular morbidity and mortality. Accurate plaque characterization is essential for risk stratification, yet conventional image interpretation is limited by variability and time. Artificial intelligence (AI) models offer automated plaque analysis across imaging modalities, demonstrating high diagnostic accuracy for detection, segmentation, quantification, and vulnerability. Integrating AI-derived biomarkers with clinical risk scores enhances major adverse cardiovascular event prediction. AI-enhanced imaging is a powerful adjunct for CAD evaluation. Challenges like data heterogeneity, algorithmic bias, and regulatory issues must be addressed for widespread clinical adoption.

AI in Various Imaging Modalities
AI models enhance plaque detection, segmentation, and quantification across IVUS, OCT, CCTA, MRI, and SPECT/PET, overcoming limitations of manual interpretation.
Comparison of AI-Enhanced Imaging Modalities
| Modality | AI Readiness | Plaque Characterization Accuracy | Current Limitations |
|---|---|---|---|
| IVUS | High | >90% (calcification, MLA, plaque burden) | Artifacts from stents/calcifications, interobserver variability |
| OCT | High | Up to 97.6% (fibrous/lipid/calcified plaques) | Limited penetration, artifacts, complex interpretation |
| CCTA | Very High | CCC > 0.95 for total plaque volume | Radiation exposure, limited by heavy calcifications or motion |
| Cardiac MRI | Moderate | Validated in carotid plaques, coronary pending | Long scan time, motion artifacts, technical barriers |
| SPECT/PET | Moderate | Strong correlation with CT and expert readers | Low spatial resolution, indirect indicators, no direct localization |

Addressing AI Implementation Barriers
Successful integration of AI in clinical practice requires addressing data quality, transparency, algorithmic bias, validation, and regulatory challenges.
Overcoming Implementation Hurdles
While AI offers immense potential, its widespread clinical adoption faces challenges. These include ensuring high-quality, diverse datasets for training, establishing transparency in 'black-box' models, mitigating algorithmic bias, conducting robust multi-center prospective validation, securing regulatory approvals, and seamlessly integrating AI tools into existing clinical workflows and EHRs.
Proactive strategies are essential to ensure safe, generalizable, and cost-effective AI solutions for cardiovascular care.
Enhanced MACE Prediction with AI
