ABSTRACT ObjectiveTo investigate the incidence and relative risk factors of post coronary artery bypass grafting (post-CABG) atrial fibrillation (AF). Methods: 312 patients with CABG were reviewed and divided into an AF group and a non-AF group. Statistical analysis was used to compare the data between the two groups and screen for risk factors of post-CABG AF. Results: 103/312 (33.01%) patients developed post-CABG AF. Univariate analysis showed that patients in AF group compared with those in non-AF group were more likely to have advanced age (≥70 years), early postoperative withdrawal of β-blockers, hypertension, left atrial enlargement (≥40mm), a history of AF, pro-longed p-wave duration (≥120ms) and increased number of grafts (≥3). Multivariate logistic regression analysis showed that advanced age (≥70 years), early postoperative withdrawal of β-blockers, hypertension, left atrial enlargement (≥40mm) and a history of AF were highly related to post-CABG AF. Conclusion: The incidence of AF in patients following CABG was 33.01% in this study. Advanced age, early postoperative withdrawal of β-blockers, hypertension, left atrial enlargement and a history of AF were independent risk factors of post-CABG AF.

    ABSTRACT: In this article, we document how an interdisciplinary committee of health professionals led to an approximate 50% reduction in the incidence of postoperative atrial fibrillation (AF) following a cardiac surgery procedure by using preoperative loading and dosing of PO amiodarone and beta blockade. Patients in this report (n = 3397) included all coronary artery bypass surgery (CABG) and valve replacement/repair procedures from January 1, 2000 to June 30, 2002. The incidence of postoperative AF for a CABG or valve replacement/repair procedure was 19.0% for period A (preprotocol) and 13.5% for period B (postprotocol). This translates into an absolute risk reduction of 5.5% or 113 actual cases of postoperative AF reduced. The role of the clinical practice specialist, a master's prepared nurse, and participation in the national Society of Thoracic Surgeon's database allowed us to track our CABG outcomes, benchmark our outcomes against both national and regional institutions, and make changes in outcomes incidence through performance improvement.
