Key result
MCAF-Net using synchronous PCG-ECG data detects CAD with ~96% accuracy.
Why the study?
Coronary artery disease is a leading cause of death worldwide, making early, non-invasive, and highly accurate detection crucial for reducing mortality.
Does the MCAF-Net deep learning model accurately detect coronary artery disease using synchronous PCG-ECG data?
Does the MCAF-Net deep learning model accurately detect coronary artery disease using synchronous PCG-ECG data?
The MCAF-Net deep learning model using synchronous PCG-ECG data demonstrated high accuracy (>96%) for the non-invasive detection of coronary artery disease.
May aid non-invasive CAD screening; hypothesis-generating pending prospective validation.
Coronary artery disease (CAD) is one of the leading causes of death worldwide. Achieving early, non-invasive, and highly accurate detection of CAD is crucial for reducing its mortality rate. This study utilizes a high-sensitivity MEMS-based PCG-ECG Synchronous Auscultation System to construct a high-fidelity clinical dataset of synchronous PCG-ECG data for CAD. Leveraging deep learning technology, we developed a Multi-scale Cross-modal Attention Fusion Network (MCAF-Net). This network extracts multi-resolution features from synchronous PCG-ECG spectrograms using an improved residual network and performs feature interaction and fusion through Mutual Cross Attention (MCA), achieving high-precision detection of CAD (96.29% on the clinical dataset, 97.69% on the public dataset).
