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 ...

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

PRACTICAL IMPLEMENTATION OF IMPEDANCE REOGRAPHY IN CARDIOLOGY – NEW APPROACHES
Background: The impedance rheocardiography is a simple, inexpensive, noninvasive method of assessment of central hemodynamics that can be used for detection of cardiovascular remodeling and thus promote an improvement of cardiovascular mortality. Modern

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
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
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 ...
