Implication
AF detection may guide risk stratification in HCM; leaves open whether intervention reduces mortality.
Key Points
- This research aims to assess the prevalence and implications of atrial fibrillation in patients with hypertrophic cardiomyopathy.
- Analyzed a large referral population with hypertrophic cardiomyopathy.
- Examined prevalence of atrial fibrillation and its impact on mortality.
- Adjusted findings for established risk factors.
- Approximately 20% of patients had atrial fibrillation.
- Atrial fibrillation significantly predicts mortality after adjusting for risk factors.

Atrial fibrillation is highly prevalent (approximately 20%) in high-risk HCM patients and serves as a strong, independent predictor of mortality.
