Extraction of Acoustic Features via Empirical Wavelet Transform to Determine Stenosis Degree of the Left Anterior Descending Artery Based on the Diastolic Heart Sounds of 75 Participants

ABSTRACT Objectives This study aimed to develop a method for extracting acoustic features to assess left anterior descending artery (LAD) stenosis severity. Methods Heart sound data were collected from 75 participants (10 diastoles per participant) using a high‐signal‐to‐noise ratio micro‐electro‐me...
