Diagnosing Coronary Artery Disease by Low Frequency Heart Sound Signatures

Abstract: Coronary Artery Disease (CAD) develops when major blood vessels that supply the heart with blood becomes damaged or diseased. As the currently available CAD detection methods are invasive, costly and not suitable to detect CAD at the early stage, more than 45% of people are dying suddenly from CAD without any prior symptoms of it. The aim of the current study is to develop a low cost method for noninvasive diagnosis of CAD, based on analysis of heart sounds obtained with a stethoscope using Auto Regressive method there by analyzing and comparing number of features that are extracted from frequency bands of heart sound recording.
