Importance of fourth heart sound and preserved left atrial function in wild-type transthyretin amyloidosis. [PDF]

ESC Heart Fail
Abstract Aims A fourth heart sound (S4) was reported to be almost never present in patients with amyloid light‐chain cardiomyopathy. There have been no reports on S4 in patients with wild‐type transthyretin amyloid cardiomyopathy (ATTRwt‐CM). This study aimed to clarify the clinical implications of S4 in patients with ATTRwt‐CM.

Evaluation of the Audicor Acoustic Cardiography Device as a Diagnostic Tool in Horses with Mitral or Aortic Valve Insufficiency

Animals
Mitral and aortic valve insufficiencies have been commonly reported in horses. The objective of this study was to establish the use of acoustic cardiography (Audicor®) in horses with aortic (AI) or mitral valve insufficiency (MI).

The role of cardiac acoustic biomarkers in monitoring patients with heart failure: A systematic literature review

ESC Heart Failure, Volume 12, Issue 2, Page 980-997, April 2025.
Abstract Heart failure (HF) creates a considerable clinical, humanistic and economic burden on patients and caregivers as well as on healthcare systems. To attenuate the significant burden of HF, there is a need for enhanced management of patients with HF.

Improved Prediction of Cardiovascular Events Using Serial Cardio‐Ankle Vascular Index (CAVI) Measurements: A 10‐Year Prospective Cohort Study

Clinical Cardiology, Volume 49, Issue 6, June 2026.
Serial CAVI measurements better predict long‐term CV events than a single baseline value, particularly for composite events, non‐fatal stroke, and CV death. In contrast, baseline CAVI showed weaker associations, with statistical significance observed only for non‐fatal CAD.

Phonocardiogram Signal Based Multi-Class Cardiac Diagnostic Decision Support System

IEEE Access, 2021
A Phonocardiogram (PCG) signal represents murmurs and sounds signals made by vibrations caused for the period of a cardiac cycle. Acoustic wave generated through the beat of the cardiac cycle propagates through the chest wall.
