Low‐Intensity Sensitive and High Stability Flexible Heart Sound Sensor Enabled by Hybrid Near‐Field/Far‐Field Electrospinning

open access: yesAdvanced Functional Materials, Volume 33, Issue 29, July 18, 2023., 2023
A hybrid near‐field/far‐field electrospinning approach is defined to achieve low‐cost fabrication and optimization of triboelectric heterostructures for heart sound sensing. The new near‐field patterned polyurethane grid spacers promote vibration enhancement and charge trapping, demonstrating record high sensitivity of 7027 mV Pa−1 and low detection ...

Association of plasma bone morphogenetic protein‐4 levels with arterial stiffness in hypertensive patients

open access: yesJournal of Clinical Laboratory Analysis, Volume 36, Issue 11, November 2022., 2022
Arterial stiffness can interact with hypertension, thereby becoming an early marker of hypertension‐mediated targeted organ damage. Plasma levels of BMP‐4 have the ability to identify increased arterial stiffness in patients with hypertension. CAVI, cardio‐ankle vascular index; BMP‐4, bone morphogenetic protein‐4. Abstract Background Arterial stiffness

Association between Cardio‐Ankle Vascular Index and Masked Uncontrolled Hypertension in Hypertensive Patients: A Cross‐Sectional Study

open access: yesJournal of Healthcare Engineering, Volume 2022, Issue 1, 2022., 2022
Detection of masked uncontrolled hypertension (MUCH) that was defined for treated hypertensive individuals who had normal office blood pressure (BP) but elevated ambulatory BP remains largely challenging. Arterial stiffness is one of the leading risk markers for hypertension and can be clinically assessed by the cardio‐ankle vascular index (CAVI). This

Deep Learning Algorithm for Heart Valve Diseases Assisted Diagnosis

open access: yesApplied Sciences, 2022
Heart sounds are mainly the expressions of the opening and closing of the heart valves. Some sounds are produced by the interruption of laminar blood flow as it turns into turbulent flow, which is explained by abnormal functioning of the valves.

A Novel Method for Measuring the Timing of Heart Sound Components through Digital Phonocardiography

open access: yesSensors, 2019
The auscultation of heart sounds has been for decades a fundamental diagnostic tool in clinical practice. Higher effectiveness can be achieved by recording the corresponding biomedical signal, namely the phonocardiographic signal, and processing it by ...
