Predictors of atrial fibrillation following coronary artery bypass surgery
Atrial fibrillation (AF) is the most frequent arrhythmia following coronary artery bypass grafting (CABG). Its multifactorial pathogenesis is not completely understood, the prevention and management also still being controversial. Although in some patients post-CABG AF is a self-limited condition, it may lead to hemodynamic instability and increased risk of systemic thromboembolism. The aim of this study was to reveal variables predictive for AF, so that high risk patients could be identified on time and appropriately managed. The study population included 169 consecutive patients who underwent CABG at our department, 130 (77%) men and 39 (23%) women, mean age 62± 8 (range 36-38) years. The patients were divided into two groups according to the presence or absence of postoperative AF, and compared for 33 perioperative demographic, clinical, laboratory and instrumental variables, wich were followed for each patient and considered to be possible predictive value. Post-CABG AF developed in 31 (18.4%) patients. Comparison of two groups revealed that patients with AF following CABG were older (66± 7 vs. 60± 8 years, p<0.05), more frequently had perioperative withdrawal of beta blockers (81% vs. 11%, p<0.05), higher incidence of coexistent chronic obstructive lung disease (24% vs. 8%, p<0.05), and longer cardiopulmonary bypass time (93± 23 vs. 84± 21 min, p<0.05). AF is common complication after CABG. Older patients and those with coexsistent chronic obstructive lung disease are at higher risk to develop such a complication. Further precipitation factors for post-CABG AF are perioperative withdrawal of beta blockers and prolonged cardiopulmonary bypass time.
