Applied Sciences, Journal Year: 2024, Volume and Issue: 14(22), P. 10201 - 10201

Published: Nov. 6, 2024

Cardiovascular diseases (CVDs) are a leading cause of mortality worldwide, with particularly high burden in India. Non-invasive methods like Phonocardiogram (PCG) analysis capture the acoustic activity heart. This holds significant potential for early detection and diagnosis heart conditions. However, complexity variability PCG signals pose considerable challenges accurate classification. Traditional signal analysis, including time-domain, frequency-domain, time-frequency domain techniques, often fall short capturing intricate details necessary reliable diagnosis. study introduces an innovative approach that leverages harmonic–percussive source separation (HPSS) to extract distinct harmonic percussive spectral features from signals. These then utilized train deep feed-forward artificial neural network (ANN), classifying conditions as normal or abnormal. The methodology involves advanced digital processing techniques applied recordings PhysioNet 2016 dataset. feature set comprises 164 attributes, Chroma STFT, CENS, Mel-frequency cepstral coefficients (MFCCs), statistical features. refined using ROC-AUC selection method ensure optimal performance.
