To the Editor: Dr Mathew and colleagues1 reported that atrial fibrillation (AF) after coronary
artery bypass graft (CABG) surgery may be associated with a range of complications.
It is unclear, however, whether AF is the cause or consequence of adverse
outcomes such as renal failure, pneumonia, mediastinitis or deep sternal wound
infections, sepsis, harvest site infections, vascular catheter infections,
and genitourinary infections. Despite this uncertainty, Mathew et al recommended
aggressive antiarrhythmic intervention for patients with recurrent AF.
