Insights
Atrial fibrillation (AF) involves complex atrial remodeling, impacting its persistence. Understanding these electrical, contractile, and structural changes is key to developing new treatments for this common heart rhythm disorder.
Area of Science:
- Cardiology
- Cardiac Electrophysiology
- Pharmacology
Background:
- Atrial fibrillation (AF) is the most common cardiac arrhythmia, particularly in older adults.
- AF significantly increases morbidity and mortality rates in the elderly population.
- Basic research over 25-30 years has elucidated the link between AF pathophysiology and atrial remodeling.
Purpose of the Study:
- To review and discuss the latest scientific understanding of atrial remodeling in AF.
- To highlight novel concepts and potential pharmacological targets for AF treatment.
Main Methods:
- Review of current literature on atrial remodeling in AF.
- Discussion of the roles of electrical, contractile, and structural remodeling.
- Identification of potential therapeutic targets.
Main Results:
- Atrial remodeling (electrical, contractile, structural) is crucial for initiating and maintaining persistent AF.
- Mechanisms include rapid ectopic firing from pulmonary veins and re-entry circuits.
- Novel concepts and pharmacological targets for AF treatment are identified.
Conclusions:
- Atrial remodeling is central to the pathophysiology of atrial fibrillation.
- Targeting remodeling processes offers promising avenues for future AF drug therapies.
Abstract:
Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia in the clinical practice. It significantly contributes to the morbidity and mortality of the elderly population. Over the past 25-30 years intense effort in basic research has advanced the understanding of the relationship between the pathophysiology of AF and atrial remodelling. Nowadays it is clear that the various forms of atrial remodelling (electrical, contractile and structural) play crucial role in initiating and maintaining the persistent and permanent types of AF. Unlike in ventricular fibrillation, in AF rapid ectopic firing originating from pulmonary veins and re-entry mechanism may induce and maintain (due to atrial remodelling) this complex cardiac arrhythmia. The present review presents and discusses in detail the latest knowledge on the role of remodelling in AF. Special attention is paid to novel concepts and pharmacological targets presumably relevant to the drug treatment of atrial fibrillation.
