Off-Pump Coronary Artery Bypass, Atrial fibrillation, HATCH score, Neutrophil to lymphocyte ratio


Backround: Postoperative atrial fibrillation (PoAF), the most common arrythmia observed in 18-40% of patients following coronary artery bypass surgery, may cause hemodynamic disturbances and increase embolism risk. The aim of this study was to investigate the relationship of HATCH score with PoAF in patients who underwent off-pump coronary artery bypass grafting (OPCABG) and evaluate the effect of preoperatively calculated neutrophil-to-lymphocyte ratio (NLR)
on PoAF.

Methods: Patients who underwent OPCABG between January 2014 and January 2019 were included in the study. Preoperative and postoperative data retrospectively were obtained. Patients who did not develop PoAF during the postoperative hospitalization period constituted Group 1; those who did were classified as
Group 2.

Results: Ninety-seven patients (69 males and 28 females) with a mean age of 54.4 ± 11.1 years constituted Group 1, and 26 patients (17 males and 9 females) with a mean age of 61±12.6 years constituted Group 2. Significant differences were observed between the 2 groups, in terms of age and HATCH scores (P = .025 and P < .001, respectively). NLR, number of distal anastomoses, intensive care unit (ICU) stay times, and total hospitalization times were significantly higher in Group 2 (P = .021, P = .021, P < .001, P < .001, respectively). HATCH score was identified as an independent predictor of AF development following OPCABG surgery (OR: 2.125, 95 % CI: 1.296–3.482,
P = .003).

Conclusion: In light of our study, HATCH scores of all patients preoperatively may be calculated so that preventive precautions are taken for high-risk patients.
