Abstract Coronary artery disease (CAD) remains a major contributor to morbidity and mortality worldwide. Heart sound analysis has been investigated as a noninvasive approach to CAD detection, although existing evidence has been inconsistent. This systematic review evaluated the diagnostic performance of heart sound analysis for identifying CAD (≥50% stenosis). A search of four databases identified 1082 records, among which 40 studies involving 13,814 participants met the inclusion criteria.

1. Introduction Evaluating left ventricular (LV) filling pressures is essential for establishing the diagnosis, guiding therapy, and determining prognosis of heart failure patients [1]. Although invasive measurements of LV filling pressures are the current gold standard, they are not routinely performed in patients.
