Atrial cardiomyopathy as a multidomain disease: longitudinal evidence for autonomic remodelling

EuropacePublished

  • Prospective cohort study

Authors' conclusion

Atrial cardiomyopathy is a cumulative, multidomain disease process in which structural, electrical, and autonomic abnormalities define atrial disease burden. Longitudinal autonomic remodelling constitutes an independent and evolving axis within this framework
