Comparison of the Expert Guidelines With Artificial Intelligence-Driven Echocardiographic Assessment of Diastolic
Insights
A new deep learning model shows superior accuracy in assessing heart failure diastolic function and left ventricular filling pressures compared to current guidelines. This AI approach uses routine echocardiograms, offering a more accessible and effective tool for diagnosis and risk stratification.
Area of Science:
- Cardiology
- Artificial Intelligence
- Medical Imaging
Background:
- Accurate assessment of diastolic function and left ventricular (LV) filling pressure is crucial for heart failure diagnosis and risk stratification.
- Current guideline algorithms utilize complex parameters often unavailable in routine clinical practice, hindering consistent application.
Purpose of the Study:
- To compare the diagnostic and prognostic performance of the 2016 and 2025 American Society of Echocardiography (ASE) guidelines with a deep learning (DL) model.
- The DL model was developed using routinely acquired echocardiographic variables.
Main Methods:
- The study evaluated guideline-based algorithms and a DL model in the Atherosclerosis Risk in Communities (ARIC) cohort (n=5450) for prognostication.
- Invasive hemodynamic validation was performed in cohorts from the US (n=83) and Japan (n=130) to assess the detection of elevated LV filling pressure.
Main Results:
- The DL model demonstrated superior prognostic performance in the ARIC cohort compared to both 2016 and 2025 ASE guidelines (C-index: 0.676 vs. 0.638 and 0.602, respectively; p<0.001).
- In diagnostic validation, the DL model showed higher performance than the 2025 guidelines in the US cohort (AUC: 0.879 vs. 0.822; p=0.041) and outperformed both guidelines in the Japanese cohort (AUC: 0.816 vs. 0.634 and 0.694; p<0.05).
Conclusions:
- A deep learning model utilizing routinely available echocardiographic parameters significantly improved diagnostic and prognostic performance.
- This AI-driven approach offers a scalable and potentially more accessible alternative for assessing diastolic function and LV filling pressures compared to current guideline-based methods.
Backgound:
Accurate assessment of diastolic function and left ventricular (LV) filling pressure is central to heart failure diagnosis and risk stratification. Contemporary guideline algorithms rely on complex parameters that are not consistently available in routine clinical practice.
Objective:
To compare the diagnostic and prognostic performance of the 2016 American Society of Echocardiography/European Association of Cardiovascular Imaging (ASE/EACVI) and 2025 ASE guidelines with a deep learning model based on routinely acquired echocardiographic variables.
Methods:
This study evaluated the guideline-based algorithms and a deep learning model in participants from the Atherosclerosis Risk in Communities (ARIC) cohort (n=5450) for prognostication and two invasive hemodynamic validation cohorts from the United States (n=83) and Japan (n=130) for detection of elevated left ventricular filling pressure.
Results:
In the ARIC cohort, the deep learning model demonstrated superior prognostic performance compared with the 2016 and 2025 guidelines (C-index: 0.676 vs. 0.638 and 0.602, respectively; both p<0.001). Similar findings were observed among participants with preserved ejection fraction (C-index: 0.660 vs. 0.628 and 0.590; both p<0.001), with improved performance compared with the H 2 FPEF score (C-index: 0.660 vs. 0.607; p<0.001). In the US hemodynamic validation cohort, the deep learning model showed higher diagnostic performance than the 2025 guidelines (AUC: 0.879 vs. 0.822; p=0.041) and similar performance compared with the 2016 guidelines (AUC: 0.879 vs. 0.812; p=0.138). In the Japanese hemodynamic validation cohort, the deep learning model outperformed both guidelines (AUC: 0.816 vs. 0.634 and 0.694; both p<0.05).
Conclusions:
A deep learning model leveraging routinely available echocardiographic parameters demonstrated improved diagnostic and prognostic performance compared with contemporary guideline-based approaches, potentially offering a scalable alternative for assessing diastolic function and left ventricular filling pressures.
