Abstract
ABDELHAMID, Ibrahim et al. Angiographic predictors of post-operative atrial fibrillation after coronary artery bypass grafting. Rev. mex. angiol. [online]. 2020, vol.48, n.4, pp.123-128. Epub Aug 23, 2021. ISSN 2696-130X. https://doi.org/10.24875/rma.20000028.
Background:
Early postoperative atrial fibrillation (POAF) has been reported following coronary artery bypass graft (CABG). This study aims to detect the coronary angiographic predictors of POAF.
Methods:
This is a prospective study that included 100 patients with CAD and sinus rhythm scheduled for CABG. Exclusion included abnormal rhythm, impaired LV systolic function, congenital heart diseases, concomitant valve replacement or previous cardiac operation.
Results:
Patients were classified into: group I included 22 patients (22%) who developed POAF and Group II: included 78 patients (78%) patients who remained in sinus rhythm. Group I were significantly older than group II (mean age of 65 ± 6.25 in group I versus 54.5 ± 6.7 in group II, p value = 0.001).Left main coronary artery (LM) involvement was higher in group I (50%) versus group II (23.07%), p value = 0.014. There was no significant difference between the two groups regarding number of grafts and echocardiographic data.
Conclusion:
In our study, patients with advanced age, and those with left main lesion had a higher rate of POAF.
