Abstract

Background:Atrial fibrillation (AF) is the most common cardiac dysrhythmia; it occurs following coronary artery bypass graft (CABG) surgery. The occurrence of this dysrhythmia causes hemodynamic disorders, prolongs the duration of hospitalization, and increases costs.
 
Methods:The present retrospective cohort study was conducted using the census method on 330 patients. Data were extracted from the records of patients undergoing CABG and were used to fill in the data collection form. The data were analyzed using the independent samples t-test and the χ2 test in SPSS, version 21, at the alpha level of 0.05.
 
Results:The mean age of the patients was 61.76 ± 9.2 years, and 70.1% were male. The incidence of AF was significantly associated with mean age, the body mass index, creatinine, and the consumption of diuretic medications (P < 0.05). However, sex, paraclinical results (ie, sodium, potassium, and the ejection fraction), clinical history (ie, hypertension, hyperlipidemia, diabetes, smoking, a history of myocardial infarction, and anterior myocardial infarction), medications (ie, beta-blockers, calcium channel blockers, angiotensin receptor blockers, and statins), and the number of involved arteries did not affect the incidence of AF (P > 0.05).
 
Conclusions: Considering the prevalence and importance of AF, effective preoperative risk factors can be decreased or eliminated through interventions, thereby reducing the incidence of this cardiac dysrhythmia. (Iranian Heart Journal 2020; 21(3): 25-32)
