Association between the use of non-antiarrhythmic drugs and postoperative atrial fibrillation

Int J Cardiol. 2010 Oct 8;144(2):304-6. doi: 10.1016/j.ijcard.2009.02.029. Epub 2009 Mar 17.


Purpose: To evaluate the association between statins, N-acetylcysteine (NAC) and angiotensin converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) and postoperative atrial fibrillation (AF).

Methods: A total of 590 patients undergoing coronary artery bypass and/or valve surgery were studied. An AF episode lasting >5 min during hospitalization was accepted as endpoint.

Results: AF rate was 18% (n=106). Multivariable positive predictors of AF included age ≥ 65, left atrial diameter ≥ 45 mm, cross clamp time; negative predictors included use of left internal mammarian artery, NAC, and ACEIs or ARBs.

Conclusions: ACEIs or ARBs and NAC is associated with low incidence of postoperative AF, however, this association was not found with statin or combined use these agents.
