Amiodarone-induced thyrotoxicosis in heart failure with a reduced ejection fraction: A retrospective cohort study.

Background: Amiodarone-induced thyrotoxicosis (AIT) is associated with significant morbidity and mortality. We aimed to describe AIT and its clinical outcomes in patients with heart failure with reduced ejection fraction (HFrEF).

Methods: We performed a retrospective chart review at a heart failure center in Winnipeg, Canada.
