Atrial fibrillation (AF) is the most common sustained arrhythmia seen in patients with transthyretin amyloid (ATTR) cardiomyopathy. 1 Trials have shown reductions in all-cause mortality, cardiac hospitalization, and functional decline in patients with ATTR cardiomyopathy. 2 However, its effect on incidence of AF is scarcely studied.We performed a retrospective review of 473 patients who were treated for cardiac amyloidosis at Columbia University Irving Medical Center between 2008 and 2019. The presence of AF in patients was confirmed by reviewing the patients’ 12-lead electrocardiograms, cardiac devices, and Holter monitors. Incident AF was defined as a recorded AF event of at least 30 seconds in duration. The protocol was approved by the Institutional Review Board. Of the 473 patients diagnosed with cardiac amyloidosis, 129 patients (27%) had not been diagnosed with AF at the time of diagnosis with ATTR cardiomyopathy. Of these patients, 36% had a confirmed genetic mutation and 43% had genetic testing without a mutation. Mean age of this cohort was 73.7+ 8.9 years, and the majority were male (87%). Average left ventricular ejection fraction was 49%+ 16%, and 70 (54%) patients required anticoagulation. Overall, of the 129 patients with no history of AF, 43 patients (33%) were started on tafamidis. There were no statistically significant differences between the 2 groups (taking tafamidis vs not taking tafamidis) in rates of prior history of hypertension (55% for those not receiving tafamidis vs 57% of those on tafamidis, P= 0.79), obesity (13% vs 21%, P= 0.28), diabetes mellitus (19% vs 7%, P= 0.08), coronary artery disease (26% vs 33%, P= 0.46), or left atrial diameter (4.3 vs 4.6 centimeters, P= 0.13). There was a larger number of African-American patients in the group not receiving tafamidis (30% vs 12%, P= 0.02). There was no
