AI advances heart sound classification for cardiovascular disease detection

Researchers have developed a novel approach to classify cardiovascular diseases using multimodal and multichannel heart sound data. By combining traditional signal processing with denoising diffusion models like WaveGrad and DiffWave, they created an augmented dataset. This dataset was then used to fine-tune a Wav2Vec 2.0-based classifier, achieving state-of-the-art performance on various datasets, including single-channel phonocardiogram (PCG), synchronized PCG and electrocardiogram (ECG) signals, and multichannel PCG (mPCG) from a wearable vest.
