Use of amiodarone for atrial fibrillation in patients with preexisting pulmonary disease in the AFFIRM study

In the Atrial Fibrillation Follow-up Investigation of Rhythm Management study, preexisting pulmonary disease did not preclude the use of amiodarone. Preexisting pulmonary disease was associated with a higher risk of pulmonary death and had a higher risk of diagnosed amiodarone pulmonary toxicity. However, use of amiodarone in the presence of preexisting pulmonary disease did not increase pulmonary death and all-cause mortality rates. Cautious use of amiodarone to treat atrial fibrillation appears acceptable in elderly patients with atrial fibrillation, even if preexisting pulmonary disease is present.
