Inflammation in the Pathogenesis of Arrhythmogenic Cardiomyopathy: Secondary Event or Active Driver?

Area of Science:

• Cardiology
• Genetics
• Immunology

Background:

• Arrhythmogenic cardiomyopathy (ACM) is an inherited heart disease causing progressive fibro-fatty myocardial replacement.
• ACM leads to heart failure and sudden cardiac death, with inflammation implicated in its progression.
• The precise role of inflammation in ACM pathogenesis remains unclear, with debate on whether it's a primary cause or secondary response.

Purpose of the Study:

• To review the current understanding of inflammation in arrhythmogenic cardiomyopathy.
• To explore proposed molecular players and triggers involved in the inflammatory process of ACM.
• To highlight the importance of inflammation research for developing novel therapeutic strategies.

Main Methods:

• Review of existing literature on inflammation in arrhythmogenic cardiomyopathy.
• Focus on studies utilizing in vivo and in vitro models to investigate inflammatory mechanisms.
• Synthesis of data on inflammatory cell infiltrates and mediators in ACM patients.

Main Results:

• Inflammation is characterized by inflammatory cell infiltration and mediators in ACM hearts and blood.
• Various molecular players and triggers are proposed to be involved in ACM-related inflammation.
• In vivo and in vitro models provide insights into the complex inflammatory pathways in ACM.

Conclusions:

• Further investigation into the molecular basis of inflammation in ACM is crucial.
• Understanding inflammation's role could identify novel therapeutic targets, including anti-inflammatory treatments.
• Targeting inflammation may offer new perspectives for managing ACM, heart failure, and sudden cardiac death.
