Direct reprogramming of cardiomyocytes into cardiac Purkinje-like cells

open access: yesiScience, 2022
Summary: Currently, there are no treatments that ameliorate cardiac cell death, the underlying basis of cardiovascular disease. An unexplored cell type in cardiac regeneration is cardiac Purkinje cells; specialized cells from the cardiac conduction ...

Engineering a conduction-consistent cardiac patch with rGO/PLCL electrospun nanofibrous membranes and human iPSC-derived cardiomyocytes

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
The healthy human heart has special directional arrangement of cardiomyocytes and a unique electrical conduction system, which is critical for the maintenance of effective contractions.

Desmin variants: Trigger for cardiac arrhythmias?

open access: yesFrontiers in Cell and Developmental Biology, 2022
Desmin (DES) is a classical type III intermediate filament protein encoded by the DES gene. Desmin is abundantly expressed in cardiac, skeletal, and smooth muscle cells.

Transcriptional control of cardiac conduction system development and function [PDF]

open access: yes, 2020
The cardiac conduction system initiates and propagates the electrical impulse that is required for the coordinated contraction of the heart. Defects in its development or function can lead to conduction disorders, life-threatening arrhythmias and cardiac

A Case of Complete AV Blockade in Patient with Lyme Borreliosis

open access: yesАрхивъ внутренней медицины, 2022
Lyme disease (tick-borne borreliosis) is an infectious vector-borne natural focal disease that tends to a chronic and recurrent course with a predominant damage to the skin, nervous system, musculoskeletal system and heart. Cardiac features is manifested,

Identification of heart rate-associated loci and their effects on cardiac conduction and rhythm disorders [PDF]

open access: yes, 2011
Elevated resting heart rate is associated with greater risk of cardiovascular disease and mortality. In a 2-stage meta-analysis of genome-wide association studies in up to 181,171 individuals, we identified 14 new loci associated with heart rate and ...

Revolutionizing cardiovascular medicine: targeted therapies for the cardiac conduction system

open access: yesThe Journal of Clinical Investigation, 2022
Arrhythmogenic cardiovascular disorders are associated with considerable morbidity and mortality. Whether cardiac conduction disease is caused by genetic defects, procedural perturbations, valvular disease, ischemia, aging, or heart failure, new ...

Left bundle branch pacing: An evolving site for physiological pacing

open access: yesJournal of Arrhythmia, 2021
For patients with symptomatic bradyarrhythmia, cardiac pacing is the only appropriate treatment option. Electrical and mechanical dyssynchrony caused by traditional right ventricular apical pacing leads to left ventricular dysfunction and atrial ...

The sophisticated architecture of the rat atrioventricular node [PDF]

open access: yes, 2005
In the mammalian heart, the action potential spontaneously generated in the sinoatrial (SA) node propagates through the atria to reach the atrioventricular (AV) node.

Autopsy for Medical Diagnostics: Finding the Cause of Sudden Unexpected Death through Investigation of the Cardiac Conduction System by Serial Sections

open access: yesDiagnostics, 2023
Sudden unexpected death (SUD) is a fatal event that occurs in an apparently healthy subject in a way that such an abrupt outcome could have not been predicted.
