Upper panel: AF risk score according to IRAF incidence. AF risk score was calculated on age, gender, arterial hypertension, and valvular heart disease (Shanafelt et al.). Percentages of patients developing or not developing IRAF are shown divided into four risk categories. IRAF cases were mainly in the high risk group (≥ 5 RF), p < 0.001. AF atrial fibrillation. IRAF ibrutinib-related atrial fibrillation. RF risk factors. Lower panel: main echocardiographic characteristics associated with IRAF. LA diameter, area, and volume were increased in IRAF patients compared to the others, significantly for the former two parameters (p = 0.02 and p = 0.03, respectively). LA left atrium, IRAF ibrutinib-related atrial fibrillation
