Clinical lessons from an elderly man with amiodarone-induced interstitial lung disease.

To the Editor: An 82-year-old man was in relatively good health despite a background of hypertension, chronic kidney disease stage 4 (estimated glomerular filtration rate 15 30 ml/min) and extensive vascular disease requiring carotid endartectomy, coronary artery bypass grafting, repair of an abdominal aortic aneurysm, and stenting of both renal arteries. In May 2005 he developed rapid atrial flutter after an episode of acute coronary syndrome. He was successfully cardioverted to sinus rhythm. After a loading dose of amiodarone he continued on 200 mg daily, and remained in sinus rhythm.
