Why the study?
The contribution of various etiological factors and atrial fibrillation to the development of differential atrial cardiomyopathy phenotypes had not been robustly quantified.
Population
European cohort undergoing cardiac surgery with LA (n=95) and RA (n=76) appendage samples
Comparison
Histological features compared across clinical characteristics including AF, HF, sex, and age
Design
Cohort study

Should not yet change practice in atrial fibrillation; leaves open sex-stratified phenotyping trials in persistent AF and heart failure.
Histological phenotypes of atrial cardiomyopathy vary significantly by patient characteristics, with fibrotic remodeling driven by female sex, persistent atrial fibrillation, and heart failure, whereas cardiomyocyte hypertrophy is more common in men.
Winters et al. (2023) studied this question.
