Predictors of Atrial Fibrillation Following Coronary Artery Bypass Grafting
Overview
Affiliations
Background: Atrial fibrillation (AF) is a frequent and serious complication of coronary artery bypass graft (CABG) surgery.
Methods: We undertook a retrospective review of the records of patients undergoing CABG at Imam Ali Hospital between February 1, 2003 and February 1, 2006. The patients were divided in two groups, ie, Group A (AF) and Group B (no AF). The association between the occurrence of AF following CABG and other variables was compared with respect to continuous or categorical variables by t-test and χ(2)-test.
Results: Multivariate logistic regression analysis of potentially predictive factors in univariate analysis showed that opium use, type of operation, and crossclamp time were predictors of AF following CABG.
Conclusion: This study identifies some new predictors of postoperative AF, control of which could lead to a lower incidence of AF and reduced morbidity, mortality, and resource utilization for patients undergoing cardiac surgery.
