The role of the systemic inflammatory response index in predicting postoperative atrial fibrillation.

Abstract

Objective: The aim of the present study was to determine the effect of systemic inflammatory response index in predicting the development of postoperative atrial fibrillation after isolated coronary artery bypass grafting (CABG).

Methods: The study was conducted at Nevşehir State Hospital, a secondary healthcare center. Patients who underwent elective isolated CABG between October 2018, when the first open-heart surgery was performed at our center, and December 2022 were included. The patients' data were retrospectively reviewed and recorded.

Results: A total of 66 patients were included in the study (mean age: 64.14±8.59 years). Of these patients, 44 (66.7%) were male and 22 (33.3%) were female. Postoperative atrial fibrillation was present in 22 (33.3%) patients. Although the systemic inflammatory response index and systemic immune-inflammatory index values were higher in the patient group that developed postoperative atrial fibrillation, no significant difference was noted (p>0.050). Additionally, age and a family history of coronary artery disease were identified as important factors that significantly affected the development of postoperative atrial fibrillation (p=0.048 and p=0.01, respectively).

Conclusion: To the best of our knowledge, no study has investigated the relationship between postoperative atrial fibrillation and the systemic inflammatory response index. Although the present study did not find a statistically significant difference, our findings support the role of inflammation in predicting postoperative atrial fibrillation.
