Insights
Atrial fibrillation (AF) increases stroke risk, but current scoring systems overlook atrial cardiomyopathy (ACM). This review examines the clinical significance of different ACM types for better risk assessment.
Area of Science:
- Cardiology
- Electrophysiology
- Pathophysiology
Background:
- Atrial fibrillation (AF) is a leading cause of thromboembolic events.
- The CHA2DS2-VASc score estimates stroke risk but does not incorporate atrial cardiomyopathy (ACM).
- Expert consensus acknowledges the role of ACM in AF pathophysiology and management.
Purpose of the Study:
- To review existing data on the clinical importance of various atrial cardiomyopathy (ACM) classifications.
- To highlight the potential of ACM assessment in refining thromboembolic risk stratification for AF patients.
Main Methods:
- Literature review of studies investigating atrial cardiomyopathy.
- Analysis of data correlating ACM types with clinical outcomes in atrial fibrillation.
- Synthesis of findings from expert consensus documents on ACM and AF ablation.
Main Results:
- Current risk scores for AF-related thromboembolism do not account for underlying pathophysiological changes in ACM.
- Different types of ACM, as classified in expert consensus, have distinct clinical implications.
- Understanding ACM subtypes may offer a more nuanced approach to risk assessment.
Conclusions:
- Atrial cardiomyopathy is a critical factor in AF-related thromboembolic risk that warrants further investigation.
- Integrating ACM assessment into clinical practice could improve risk stratification and patient management.
- Future research should focus on validating the clinical utility of ACM classification in predicting thromboembolic events.
Abstract:
Atrial fibrillation (AF) is the most common cause of thromboembolic complications. The risk of suffering a thromboembolic complication correlates with the CHA2DS2-VASc score identifying patients at increased risk. It is based on patient age, prior thromboembolic events, and clinical comorbidities, but not based on pathophysiological changes in different types of atrial cardiomyopathy (ACM) as classified in the expert consensus on ACM published in 2016. The impact of different types of ACM has also been acknowledged in the expert consensus statement on catheter ablation of atrial fibrillation. The aim of this review is to review data on clinical importance of ACMs.
