Role of beta-blockers in reducing post-operative atrial fibrillation following cardiac surgery

Authors:

Abstract
The evaluation of nine clinical investigations which studied 2,533 patients demonstrates beta-blockers reduce postoperative atrial fibrillation (POAF) after cardiac surgical procedures effectively. It is known that beta-blockers successfully decreased the occurrence of postoperative atrial fibrillation 11.1% to 52.0%. Differences in patient characteristics and drug regimen make it difficult to determine the properly adjusted beta-blocker treatment for ideal results. Thus, beta-blocker therapy for reducing postoperative atrial fibrillation cases is relevant yet additional standard protocols must be created.
