Low-intensity pulsed ultrasound treatment did not cause significant structural, functional, or electrophysiological changes in the atrial tissue of healthy rats. In MI rats, LIPUS markedly attenuated atrial electrical remodelling, fibrosis, and inflammation, thereby reducing AF susceptibility. Transcriptomic analysis demonstrated a potential role of Adam19\/transforming growth factor-\u03b2 (TGF-\u03b2)\/Smad2\/3 signalling in response to LIPUS treatment, whereas activation of Adam19\/TGF-\u03b2\/Smad2\/3 signalling worsened fibrosis and abolished the antiarrhythmic benefit of LIPUS. Similar antifibrotic and antiarrhythmic effects were reproduced in the acetylcholine\/CaCl\u2082 AF model, underscoring LIPUS as a promising non-invasive approach to attenuate AF after MI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In preclinical post-MI models, LIPUS attenuated atrial structural and electrical remodelling and lowered AF susceptibility, plausibly via modulation of an Adam19\/TGF-\u03b2\/Smad2\/3 signalling cascade. These findings are promising but preliminary; priorities include determining whether the atrial effects are direct or secondary to ventricular remodelling and altered haemodynamics, confirming mechanisms across models, defining dose\u2013response and safety and validating efficacy and translational relevance in large-animal studies and early-phase trials before any clinical
