BACKGROUND: Radiotherapy (RT) associates with long-term cardiotoxicity. In preclinical models, RT-exposure induces early cardiotoxic arrhythmias including atrial fibrillation (AF). Yet, whether this occurs in patients is unknown. METHODS: Leveraging a large cohort of consecutive esophageal cancer patients treated with thoracic-RT from 2007-2019, we assessed incidence and outcomes of incident-AF. Secondary outcomes included major adverse cardiovascular events (MACE), defined as AF, heart failure, ventricular-arrhythmias and sudden-death, by cardiac RT-dose...
