Implication
May identify fibroblast ion channels as antiarrhythmic targets in AF; leaves open in vivo validation before clinical translation.
Key Points
- This article aims to clarify the role of cardiac fibroblasts in electrical function and their implications for atrial fibrillation.
- Review of recent advancements in cardiac fibroblast molecular electrophysiology.
- Analysis of the role of ion channels such as K(+) and TRP in fibroblast function.
- Discussion on the interaction between fibroblasts and cardiomyocytes in the context of arrhythmias.
- Fibroblasts significantly influence cardiomyocyte electrical properties, including conduction and excitability.
- Excess ECM produced by fibroblasts contributes to conduction disturbances and arrhythmias.
- Identification of novel targets for antiarrhythmic therapies based on fibroblast electrical properties.
