Why the study?
Do older age, interatrial block on ECG, and reduced left atrial ejection fraction on CMR predict incident atrial fibrillation in patients with cardiac amyloidosis?
Do older age, interatrial block on ECG, and reduced left atrial ejection fraction on CMR predict incident atrial fibrillation in patients with cardiac amyloidosis?
Older age, interatrial block on ECG, and reduced left atrial ejection fraction on CMR identify patients with cardiac amyloidosis at higher risk for incident atrial fibrillation, warranting closer screening.
May support AF risk stratification in cardiac amyloidosis; hypothesis-generating and requires prospective validation before clinical adoption.
In patients with CA, older age, IAB on 12-lead electrocardiography, and reduced LAEF on cardiac magnetic resonance imaging are significant and independent predictors of incident AF. A closer screening for AF is advisable in CA patients carrying these features.
