Deep Analysis & Enterprise Applications
Select a topic to dive deeper, then explore the specific findings from the research, rebuilt as interactive, enterprise-focused modules.
ECG-AI models demonstrate consistent performance across diverse demographics (racial, age profiles) despite being trained on specific cohorts. This indicates strong generalizability from one population to another.
ECG-AI models trained on cohort study data maintain similar accuracy when applied to real-world Electronic Health Record (EHR) data, showcasing their applicability beyond controlled research settings.
Models developed using data from one ECG vendor (e.g., GE MUSE) successfully validate on data from another (e.g., EPIPHANY), suggesting robustness to variations in proprietary processing and filtering algorithms.

Case Study 1: ECG-AI for 10-year Incident HF Risk Prediction
The ECG-AI model for predicting 10-year incident HF was developed using ARIC study data (White and Black Americans). It demonstrated similar accuracy (AUC 0.76-0.80) when applied to MESA (including Chinese American and Hispanic participants) and real-world UTHSC data, indicating generalizability across populations with varying racial and age profiles. Traditional HF risk calculators (FHS-HF, ARIC-HF) showed significant decline in accuracy when applied to different cohorts, highlighting ECG-AI's superior generalizability.
Case Study 2: Detection of Left Ventricular Dysfunction (LVD) and HFpEF
A 12-lead ECG-based ECG-AI model was trained using WFBH data and externally validated on UTHSC data. It achieved comparable performance for rEF detection (AUC 0.90-0.92). While mEF and HFpEF detection showed slight statistical reduction in accuracy (AUC 0.76-0.71 and 0.73-0.64 respectively), the model's overall utility across diverse settings and ages (adult and pediatric) was demonstrated. The lead I variant showed even better generalization (AUC 0.89-0.90 for rEF).
