Key result
Women had greater areas of left-atrial low-voltage, smaller atria, and smaller cardiomyocytes compared to men, despite no differences in the degree of atrial remodeling.
Why the study?
Are there sex-related differences in left-atrial low-voltage areas and atrial remodeling that explain atrial fibrillation susceptibility?

This commentary highlights that women exhibit greater left-atrial low-voltage areas and smaller atria and cardiomyocytes than men, providing mechanistic insights into sex differences in atrial fibrillation.
Principle results of the study commented on. Women had greater areas of left-atrial low-voltage; smaller atria and smaller cardiomyocytes. There were no differences in the degree of atrial remodeling between women and men.
