Systolic third sound associated with systolic anterior motion of the mitral valve in cats with obstructive hypertrophic cardiomyopathy [PDF]

Journal of Veterinary Internal Medicine, 2023
Background Third heart sounds in cats frequently are associated with hypertrophic cardiomyopathy (HCM) but their exact characterization and timing within the cardiac cycle remains unknown.

Phonocardiography based pulse wave velocity system for non-occlusive assessment of arterial stiffness [PDF]

Frontiers in Cardiovascular Medicine
Arterial stiffness is strongly associated with vascular aging and pathology and can be assessed in many ways. Existing devices for measuring central arterial stiffness, such as carotid-femoral pulse wave velocity (PWV), are limited by high costs and the ...

AMI-SSS01 portable phonocardiographic examination with AI-assisted assessment for detecting heart failure exacerbations in home-based medical care in Japanese primary care clinics: a study protocol for a randomised controlled feasibility trial [PDF]

BMJ Open
Introduction The global prevalence of heart failure continues to increase, particularly in ageing populations. Many older patients receiving home-based medical care have limited access to standard diagnostic tools, such as chest radiography and ...

Dynamic Changes in Fourth Heart Sound in Type 2 Diabetes: Insights From Visualized Phonocardiography and SGLT2 Inhibitor Adjustment. [PDF]

Case Rep Med
The fourth heart sound (S4) is an auscultatory marker of left ventricular diastolic dysfunction (LVDD). Additionally, S4 correlates with atrial function, which is typically impaired in patients with Type 2 diabetes (T2D) but can improve with sodium–glucose co‐transporter‐2 inhibitor (SGLT2i) therapy.

The Evolving Stethoscope: Insights Derived from Studying Phonocardiography in Trainees [PDF]

Sensors
Phonocardiography (PCG) is used as an adjunct to teach cardiac auscultation and is now a function of PCG-capable stethoscopes (PCS). To evaluate the efficacy of PCG and PCS, the authors investigated the impact of providing PCG data and PCSs on how ...

Acquisition Devices for Fetal Phonocardiography: A Scoping Review [PDF]

Bioengineering
Timely and reliable fetal monitoring is crucial to prevent adverse events during pregnancy and delivery. Fetal phonocardiography, i.e., the recording of fetal heart sounds, is emerging as a novel possibility to monitor fetal health status. Indeed, due to

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.
