Executive Summary: Pioneering AI for AMI Prognosis
This research introduces HeartTTable, an innovative AI model leveraging 3D cardiac reconstruction and multimodal data to predict major adverse cardiovascular events (MACE) in acute myocardial infarction (AMI) patients post-PCI. By integrating dynamic cardiac imaging with clinical variables, HeartTTable achieves superior long-term prognostication, offering a crucial tool for personalized patient management. The model, HeartTTable, achieved a 5-year time-dependent AUCs of 0.934 and a Harrell's C-index of 0.897, significantly outperforming models based solely on clinical and CMR-derived tabular features.

HeartTTable: Multimodal Fusion for Superior MACE Prediction
0.9345-Year AUC for MACE Prediction
The HeartTTable model integrates 3D CINE reconstructions from cardiac magnetic resonance (CMR) images with 45 clinical and CMR-derived tabular variables. This multimodal approach achieved a 5-year time-dependent AUC of 0.934 (95% CI 0.907 – 0.959), significantly outperforming models based on single modalities. This highlights the critical role of comprehensive data integration in enhancing predictive accuracy for long-term prognosis.
| Model/Approach | Key Features |
|---|---|
| ReconSeg3D (3D CINE Reconstruction) |
|
| Conventional 2D CMR Images (SA cine stacks) |
|
ReconSeg3D reconstructs short-axis cine CMR stacks into temporally-resolved 3D bi-ventricular volumes. This enhanced representation of cardiac dynamics significantly improves the input for MACE prediction compared to raw 2D images, by addressing issues like inter-slice gaps and providing a more comprehensive view of cardiac structures and motion over the full cardiac cycle.

HeartTTable Model for 5-Year MACE Prediction
Impact on Post-PCI Management
The HeartTTable model provides an objective, data-driven decision support tool for clinicians managing AMI patients post-PCI. Its strong discriminative power for stratifying high- and low-risk groups, combined with its 5-year predictive capability, enables tailored postoperative treatment, rehabilitation plans, and follow-up schedules. This can significantly alleviate the burden of MACE and improve long-term patient outcomes. For instance, in a subgroup comparison, HeartTTable yielded an odds ratio of 28.207 for MACE stratification, vastly outperforming traditional scores (e.g., GRACE: 1.564, Eitel: 2.273, Glasgow: 1.865).
