BackgroundAtrial fibrillation (AF) is considered the most common supraventricular arrhythmia in patients undergoing coronary artery bypass graft (CABG). The predictive value of the SYNTAX score for post-CABG new-onset AF incidence has not been clearly evaluated. This study aimed to assess this association in patients undergoing isolated on-pump CABG.MethodThis study was done in a single-center, randomized, and observational setting. A total of 133 patients undergoing on-pump isolated CABG who were older than 18 years and had sinus rhythm were enrolled. Demographic variables of patients were recorded, and the SYNTAX score was measured for the participants. The multivariate logistic regression model was applied to identify the predictors of post-CABG new-onset AF.ResultsThe logistic regression model showed that SYNTAX score of more than 28.25 (p-value= 0.001; OR= 14.25, 95% CI= 2.90_70.11), hypertension (p-value=0.02; OR = 6.59, 95% CI = 1.23_34.57), and calcium channel blocker consumption (p-value=0.02; OR = 8.05, 95% CI = 1.43_45.42) are predictors of new-onset AF after on-pump CABG.ConclusionThis study demonstrated that patients with higher SYNTAX scores in coronary angiography are more likely to develop new-onset AF after isolated on-pump CABG. |
