Initial risk stratification of ibrutinib-associated atrial fibrillation (IAAF) may inform atrial fibrillation (AF) surveillance strategies. The performance of existing AF risk scores to predict incident AF among patients newly treated with ibrutinib is unknown.</p><p><strong>Methods: </strong>We conducted a single-center retrospective study of all patients without a history of AF who were treated with ibrutinib (2012-2016). Patient demographics were compared between cohorts by the presence of IAAF within 24 months of treatment initiation. First, the predictive ability of established AF risk models was assessed.
