This study shows endurance exercise increases proarrhythmic remodeling in pulmonary vein sleeve myocytes and the PV-LA junction, contributing to atrial fibrillation susceptibility in athletes.

This study challenges the role of resident cardiac macrophages in AV node conduction by showing no evidence of Cx43-mediated coupling and no effect of macrophage depletion on AV electrical activity.

This study uses a multi-omics approach to analyze regional differences in cardiac responses to radiation, identifying distinct molecular and structural changes in different heart regions.
