Pacemaker dependency after pacemaker implantation.

open access: yesCardiology journal, 2007
Pacemaker dependency (PD) can be defined as the risk of serious injury or death from sudden pacemaker failure, an event more dangerous than progressive rate decrease. The aim of this study was to evaluate the incidence of PD during long-term follow-up after pacing system implantation.The study included 3638 patients (mean age 65.3 +/- 10.2 years ...

Amyloid β Instigates Cardiac Neurotrophic Signaling Impairment, Driving Alzheimer's Associated Heart Disease

open access: yesAdvanced Science, EarlyView.
This research identified cardiac amyloid pathology, neurotrophic factor depletion, and reduced myocardial nerve function in a transgenic model of cerebral amyloidosis (Tg2576), Aβ‐challenged cardiomyocytes, and in human AD heart tissue. These findings carry significant diagnostic and therapeutic implications, emphasizing the role of neuro‐signaling ...

Syncope as a presenting feature of complete extrusion of a unipolar permanent pacemaker

open access: yesCHRISMED Journal of Health and Research, 2016
Complete extrusion of a permanent pacemaker is an extremely rare complication. We report a unique case of a patient presenting with syncopal episodes after complete extrusion of his implanted pacemaker.

A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions

open access: yesAdvanced Science, EarlyView.
This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...

Two cases of hemodynamic improvement by modulation of atrioventricular delay in cardiac operations

open access: yesJA Clinical Reports, 2022
Background Symptomatic sick sinus syndrome is one of the indications for pacemaker implantation, and we have to consider to program the pacemaker to an asynchronous pacing mode during an operation. Case presentation We reported two cases with a pacemaker

Gradient Ion Beams Regulate Surface Group Modification to Enhance Interfacial Charge Transport in Triboelectric Polymers

open access: yesAdvanced Science, EarlyView.
This study addresses the core scientific question of atomic‐scale structural units and their assembly mechanisms by integrating ion implantation technology— originally developed in nuclear physics research—with flexible intelligent polymers. Through this interdisciplinary approach, we have enabled on‐demand customization of surface functionalities and ...

Biocompatible Magnetopyroelectric Composite Films for Cell Stimulation

open access: yesAdvanced Science, EarlyView.
Magnetopyroelectric films couple Fe3O4 nanoparticles with pyroelectric P(VDF‐TrFE) to turn alternating magnetic fields into controlled heat and pyroelectric currents. This heavy‐metal free platform safely boosts neural progenitor cells differentiation via synergistic thermal and pyroelectrical cues, engages AKT and calcium pathways, and opens practical

PVNCRF Neurons Regulate Migraine‐Like Allodynia by Activating CRFR2 on Spinal Trigeminal Caudalis Glutamatergic Neurons

open access: yesAdvanced Science, EarlyView.
Paraventricular CRF neurons in the hypothalamus project to glutamatergic neurons of the spinal trigeminal caudal nucleus, enhancing neuronal activation and CRFR2 signaling. This pathway increases CRF release and excitatory drive, promoting central sensitization and migraine‐related behaviors. Targeting the PVN–SP5C circuit provides a potential strategy

Subacute Right Ventricle Perforation by Pacemaker Lead Presenting with Left Hemothorax and Shock

open access: yesCase Reports in Cardiology, 2015
Cardiac perforation by pacemaker is a rare but potentially fatal complication. Acute perforations occurring within twenty-four hours of insertion of pacemaker can lead to hemopericardium, cardiac tamponade, and death.
