Facts and Gaps in Exercise Influence on Arrhythmogenic Cardiomyopathy: New Insights From a Meta-Analysis Approach

Q: What is the clinical evidence from this study?

Study design: Meta-Analysis. Population: Arrhythmogenic cardiomyopathy (ACM) (n=854). Intervention: High-intensity sports activities vs. Lower physical activity habits / non-intense exercise. Primary outcome: Life-threatening arrhythmic events (LAE) (OR 2.1, 95% CI 1.43-3.8).

Key result

High-intensity sports activities are associated with a significant two-fold increase in the risk of life-threatening arrhythmic events in patients with arrhythmogenic cardiomyopathy (OR 2.1).

Why the study?

While exercise benefits physical and mental health, patients with arrhythmogenic cardiomyopathy appear to be an exception, warranting a pooled analysis of exercise influence.

Does intense exercise accelerate structural and arrhythmic progression in patients with arrhythmogenic cardiomyopathy?

Population

34 papers of animal models and clinical series regarding ACM and sports-related sudden cardiac death

Design

Systematic review and meta-analysis

Discussion

Implication

Supports restricting high-intensity sports in arrhythmogenic cardiomyopathy; reinforces current guidelines with meta-analytic evidence.

Key Points

To synthesize evidence on how physical exercise affects disease development, arrhythmic risk, and sudden cardiac death in arrhythmogenic cardiomyopathy.
Literature search across PubMed and other sources using terms related to arrhythmogenic right ventricular cardiomyopathy, sports, exercise, and sudden cardiac death.
Inclusion of 34 studies covering pre-clinical animal models and clinical series examining sports-related outcomes in arrhythmogenic cardiomyopathy.
Extraction and pooling of data to estimate the global incidence of sudden cardiac death causes in athletes and life-threatening arrhythmias in active patients.
Sports participation accelerates the arrhythmogenic cardiomyopathy phenotype, worsening both structural cardiac changes and life-threatening ventricular arrhythmias.
Restricting exercise slows clinical disease progression in affected patients and also confers protective benefits in phenotype-negative genetic mutation carriers.
Substantial knowledge gaps persist regarding non-classical phenotypes, particularly left-dominant forms and non-plakophilin-2 genotypes, which remain underrepresented in current literature.

Structured PICO

Does intense exercise accelerate structural and arrhythmic progression in patients with arrhythmogenic cardiomyopathy?

Population

854 patients with arrhythmogenic cardiomyopathy from 8 observational studies evaluating the risk of life-threatening arrhythmic events based on sports participation.

Exposure

Sports and exercise (intense vs. non-intense)

Comparator

Sedentary lifestyle or non-intense exercise

Outcome

Global incidence of causes of sudden cardiac death in sports and global estimates of life-threatening arrhythmic events (LAE) in ACM patientshard clinical

Main Result

Odds Ratio: 2.1 (95% CI 1.43–3.8)

Intense exercise accelerates both structural and arrhythmic progression in arrhythmogenic cardiomyopathy, supporting current guidelines that recommend restricting high-intensity sports in these patients.

Limitations

Great differences observed in the design of the included studies
Differences in assessing the sport performed (before recruitment, before and after, or only after)
Vast majority of patients exhibited a classical phenotype, with very small representation of non-PKP2 mutations
The percentage of patients with left ventricular involvement remains widely unknown
Applicability to non-classical ACM phenotypes is limited since left dominant ACM or non-plakophillin-2 genotypes were absent or very poorly represented in the available studies.

Solé et al. (2021) conducted a meta-analysis in Arrhythmogenic cardiomyopathy (ACM) (n=854). High-intensity sports activities vs. Lower physical activity habits / non-intense exercise was evaluated on Life-threatening arrhythmic events (LAE) (OR 2.1, 95% CI 1.43-3.8). High-intensity sports activities are associated with a significant two-fold increase in the risk of life-threatening arrhythmic events in patients with arrhythmogenic cardiomyopathy (OR 2.1).
