Exploring Glycocalyx shedding markers: A comparative analysis of plasma markers among premenopausal and postmenopausal women

Physiological Reports, Volume 14, Issue 12, June 2026.
Abstract The endothelial glycocalyx (eGC) is a protein‐rich, hairlike structure covering the luminal surface of endothelial cells, vital for vascular health. Aging and cardiovascular disease (CVD) can compromise eGC integrity, potentially preceding conventional indicators of vascular dysfunction such as reduced endothelium‐dependent vasodilation and ...

Quantitative Confounder Analysis of Electrocardiogram Signals in Cardiac Magnetic Resonance at 1.5, 3 and 7 T—Assessing Standardized Electrode Positions and Sequence Types—Towards Quality Assurance

Journal of Magnetic Resonance Imaging, Volume 63, Issue 4, Page 1140-1154, April 2026.
ABSTRACT Background The electrocardiogram (ECG) used for gating in cardiac MRI may be compromised by multiple confounders inside the scanner bore. Purpose To quantify the influence of magnetic field strengths (1.5 T/3 T/7 T), standardized electrode positions, and imaging sequences on ECG signals used for gating. Study Type Prospective.

Augmented Phonocardiogram Acquisition and Analysis [PDF]

, 2011
Heart auscultation (the interpretation of heart sounds by a physician) is a widely used screening method for heart disease. It is well documented, however, that with the exception of expert cardiologists, physicians' auscultation skills are limited. It has also been shown that standard training methods do little to improve these skills.

Time-Frequency Analysis, Denoising, Compression, Segmentation, and Classification of PCG Signals

IEEE Access, 2020
Phonocardigraphy (PCG) is the graphical representation of heart sounds. The PCG signal contains useful information about the functionality and the condition of the heart. It also provides an early indication of potential cardiac abnormalities. Extracting

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.

Transforming healthcare with large language models: Current applications, challenges, and future directions—a literature review

Journal of Intelligent Medicine, Volume 3, Issue 1, Page 8-25, March 2026.
Abstract AI‐based large language models (LLMs) have gradually made their way into various fields, transforming industries and changing the way we solve problems. LLMs have great potential in healthcare, where they can share the burden of data management, retrieval, and decision‐making.

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.

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 ...
