Mechanisms underlying atrial myopathy and atrial fibrillation

Atrial fibrillation is the most common cardiac arrhythmia worldwide and prevalence is expected to continue rising at an exponential rate with an aging population and increasing rates of obesity and diabetes globally. Atrial fibrillation is associated with an increased incidence of stroke and HF. Once atrial fibrillation is present, it can be very difficult to treat. While atrial fibrillation ablation is successful in a number of patients, approximately one-third of patients will experience recurrence of atrial fibrillation, and this can be even higher in patients with persistent atrial fibrillation. A key feature of atrial fibrillation is atrial myopathy which can include atrial enlargement/dilatation, fibrosis, metabolic and contractile dysfunction. Pathological atrial myopathy predisposes to atrial fibrillation, heart failure and stroke. There is a clinical need to identify pathological atrial myopathy and atrial fibrillation risk earlier to improve outcomes. By understanding mechanisms and prevention/treatment strategies that prevent/attenuate/reverse atrial myopathy and atrial fibrillation, we will be better positioned to tackle this very challenging arrhythmia.
We welcome basic/discovery, preclinical and clinical original articles, meta-analysis and reviews, covering, but not limited to, the following topics:
- Molecular mechanisms underlying atrial enlargement, fibrosis, metabolism, function, and atrial thrombosis.
- Impact of obesity, diabetes and aging on atrial biology and susceptibility to atrial fibrillation.
- Preclinical studies assessing novel therapeutic strategies to prevent/treat atrial pathology and atrial fibrillation.
- Clinical studies evaluating catheter ablation or new therapeutic approaches.
- Assessment and identification of new/improved blood markers, imaging measures (echocardiography, PET, MRI), risk prediction models, and digital technology/artificial intelligence methods for identifying atrial myopathy, atrial thrombosis and/or atrial fibrillation earlier.
- Associations and links between atrial myopathy and atrial fibrillation with heart failure, stroke, neurological decline and pathology in other organs.
- Assessment of exercise/physical activity and/or other lifestyle factors on prevention or attenuation of atrial myopathy and atrial fibrillation.
- Studies characterizing/understanding mechanisms underlying atrial myopathy and atrial fibrillation in endurance athletes.
We encourage the submission of research which has examined these topics in both males and females.

The Collection will publish original research Articles, Reviews, Perspectives and Comments (full details on content types can be found here). Papers will be published in npj Cardiovascular Health as soon as they are accepted and then collected together and promoted on the Collection homepage. All Guest Edited Collections are associated with a call for papers and are managed by one or more of our Editorial Board Members and the journal's Editors.
This Collection welcomes submissions from all authors – and not by invitation only – on the condition that the manuscripts fall within the scope of the Collection and of npj Cardiovascular Health more generally. See our editorial process page for more details.
All submissions are subject to the same peer review process and editorial standards as regular npj Cardiovascular Health articles, including the journal’s policy on competing interests. The Editor has no competing interests with the submissions, which they handle through the peer-review process. The peer review of any submissions for which the Editor has competing interests is handled by another Editorial Board Member who has no competing interests. See our Collections guidelines for more details.
