Context
Atrial fibrillation is the most frequent arrhythmia following cardiac surgery. Many risk
factors for this problem have been studied.
Aims
The objective was to investigate the relation between perioperative hyperglycemia
and postoperative atrial fibrillation (POAF) after coronary artery bypass grafting.
Settings and design The study was a retrospective observational study that took
place at Benha University Hospital, which is a tertiary referral center.
Patients and methods
The study was conducted on 100 patients who were admitted for coronary artery
bypass grafting. Patients were divided into two groups: group A included 50 patients
who developed POAF and group B included 50 patients who did not.
Statistical analysis
Data were imported into Statistical Package for the Social Sciences (SPSS version
20.0) software for analysis. Qualitative data represented as number and
percentage and tested by the χ2
-test. Quantitative data were represented by
mean±SD and tested by t-test or Mann–Whitney.
Results
The authors have found that a history of diabetes mellitus, mean postoperative
blood sugar (BS), and maximum postoperative BS levels were more significant
