The Effects of Serum Crp Level on Postoperative Atrial Fibrillation in Patients Who Had Coronary Bypass Surgery

Abstract

Coronary artery bypass grafting (CABG) is the most common cardiac operation performed worldwide. We aimed to evaluate the relationship between post-operative serum C-reactive protein (CRP) level and atrial fibrillation (AF) in patients who received CABG. A total of 198 patients who had undergone CABG between January 2016 and February 2018 in our cardiovascular surgery clinics were included in the study. According to CRP levels, patients were into 2 groups; Group 1 serum CRP level <8.0mg/L and Group 2 serum CRP level ≥8.0mg/L. There were 82 patients in Group 1 (31 Female, 51 Male) and 116 patients (48 Female, 68 Male) in Group 2. Patients who died within 30 days after CABG were excluded. While the mean age of the cohort was 61.2 ± 8.1 years; it was 59.8 ± 9.4 years and 61.5 ± 7.4 years in Group 1 and 2, respectively. AF was observed in 65 patients (32.8%) including 13 patients in Group 1 (15.8%) and 52 patients (44.8%) in Group 2. The rate of AF was significantly higher in Group 2 (p<0.05). Coronary artery disease itself is significant risk factor of mortality and morbidity. Our study showed that post-operative serum CRP level would be an indicator of AF. Although increased levels of CRP alone cannot be the primary cause of AF, the rate of post-operative AF was higher in CABG patients with high CRP level. © 2018, Yuzuncu Yil Universitesi Tip Fakultesi.
