AI‐Based Non‐Invasive Continuous Blood Pressure Monitoring and Estimation System

Advanced Sensor Research, Volume 5, Issue 1, January 2026.
An AI‐based biosensor pipeline integrates Apple Watch electrocardiogram (ECG), a custom digital stethoscope, and a blood‐pressure cuff to generate and validate 24‐hour cuffless blood‐pressure waveform prediction. Using a wavelet‐preprocessed ECG and a long short‐term memory model trained on MIMIC‐II and Autonomic Aging datasets, the system estimates ...

Rivero-Carvallo Sign in Bioprosthetic Tricuspid Valve Stenosis

JACC: Case Reports, 2023
In a case with bioprosthetic tricuspid stenosis, simultaneous phonocardiogram and Doppler recordings revealed that the louder diastolic rumble in inspiration (Rivero-Carvallo sign) is related to increased tricuspid gradient caused by less prominent ...

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).

Database for the interpretation of phonocardiograms

Journal of Physics: Conference Series, 2019
Abstract Using LabVIEW software, we built a set of images corresponding to cardiac sounds associated to diagnosed cardiac diseases. This constitutes an image database which facilitates phonocardiograms interpretation, also we made the correlation with diseases and the possible causes.

Impact of Blood Pressure Across the Life Course on Arterial Stiffness in Midlife: The Mediating Role of Metabolic Factors

MedComm, Volume 6, Issue 11, November 2025.
This 30‐year cohort study demonstrates that elevated blood pressure (BP) since childhood contributes to arterial stiffness in midlife, with adult BP showing the strongest association. The triglyceride–glucose index partially mediates this relationship, especially in males. These findings highlight the importance of early BP control and metabolic health

Carotid and regional arterial stiffness and dementia‐related imaging biomarkers in the Multi‐Ethnic Study of Atherosclerosis (MESA)

Alzheimer's &Dementia, Volume 21, Issue 10, October 2025.
Abstract INTRODUCTION Arterial stiffness measured within various arterial beds may be differentially associated with neuroimaging biomarkers of dementia. METHODS We related carotid and regional (cardio‐ankle vascular index [CAVI] and heart‐ankle pulse wave velocity [haPWV]) arterial stiffness measures to biomarkers (gray matter volume [GMV], white ...
