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.

<strong>Objective:</strong> To investigate the association of platelet to lymphocyte ratio to mortality and morbidity after coronary artery bypass grafting operation.<br /><strong>Methods:</strong> We evaluated records of 916 patients who underwent coronary artery bypass grafting operation between January 2009 and May 2014 retrospectively. Patients were grouped as Group 1 (n = 604) if the platelet to lymphocyte ratio was above 142 and Group 2 (n = 312) if platelet to lymphocyte ratio was below 142.<br /><strong>Results:</strong> The number of patients who developed a neurologic event during the hospital stay and in the first postoperative month was 7 (1.2%) in Group 1 and 12 (3.8%) in Group 2 for which the difference was statistically significant (P = .007). Early term mortality occurred in 3 patients (0.5%) in Group 1 and in 10 patients (3.2%) in Group 2 for which the difference was statistically highly significant (P = .001). In univariate and multivariate regression analysis, the preoperative platelet to lymphocyte ratio was determined as an independent risk factor for occurrence of atrial fibrillation in the early postoperative period, reoperation for sternum dehiscence, occurrence of a neurologic event, prolonged stay in the hospital and mortality.<br /><strong>Conclusion:</strong> In this study, elevated levels of platelet to lymphocyte ratio were associated with mortality and morbidity after coronary artery bypass grafting operation.

Objective. To study the effect of preoperative atrial fibrillation (AF) on the risk of stroke and long-term mortality after Off Pump Coronary Artery Bypass (OPCAB). Materials and methods. A retrospective analysis of the results of OPCAB in 212 patients with coronary artery disease (CAD), who were operated on from May 2009 to November 2013, was carried out. After propensity score matching, patients were divided into 2 groups: Group I 82 patients with sinus rhythm (SR) before surgery, Group II (control) 102 patients with AF before surgery. The average age of the included patients was 61 6.7 years, with 95 % CI: 6062. Fifty-four (29.3 %) patients were over 65 years of age. There were 162 men (88 %) and 22 women (12 %). The median follow-up was 93.5 (66.7102.0) months. Results. The time spent in the clinic was statistically significantly shorter in the SR group than in the AF group (10 (911) and 14 (1116) hours, respectively, p 0.001). There was no statistically significant difference in the number of perioperative myocardial infarctions (in the group with SR it occurred in 1 (1.2 %) patient, in the group with AF 2 (2 %), p = 0.7), strokes (in the group with SR 1 (1.2 %), in the group with AF 3 (2.9 %), p = 0.6), as well as a 30-day mortality (in the group with SR it was 0 %, in the group with AF 3 (2.9 %), p = 0.2). In the long-term postoperative period, there were statistically significantly fewer strokes in the group with SR than in the group with AF (in the group with SR, the 10-year stroke freedom was 88.8 %, and in the group with AF 71.8 %, p = 0.018), and also better long-term survival in the group with sinus rhythm (in the group with SR, the 10-year survival rate was 79 %, in the group with AF 63.9 %, p = 0.016). Conclusions. In the group with preoperative AF, the frequency of distant strokes and deaths is higher than in patients with sinus rhythm.
