Key result
The absence of COPD (OR 0.202) and lower preoperative platelet counts (OR 0.995) were identified as independent predictors of excessive bleeding following coronary artery bypass grafting surgery.
Why the study?
Postoperative bleeding is one of the most frequently encountered complications following CABG, prompting investigation of preoperative and intraoperative risk factors affecting it.

Reduced preoperative platelet count and the absence of COPD are independent risk factors for excessive bleeding following CABG surgery, which in turn increases postoperative complications and mortality.
May aid preoperative bleeding risk assessment in CABG; leaves open prospective validation before clinical adoption.
Aim: Postoperative bleeding is one of the most frequently encountered complications following coronary artery bypass grafting (CABG). This study aims to investigate preoperative and intraoperative risk factors affecting postoperative bleeding in CABG surgery. Methods: A total of 242 patients who underwent CABG between March 2019 and January 2023 were retrospectively analyzed. Based on postoperative bleeding volume, patients were classified into two groups: normal bleeding (Group N) and excessive bleeding (Group B). The groups were compared in terms of demographic, clinical, and perioperative variables. Results: Patients in Group B demonstrated significantly lower preoperative platelet counts (p=0.005), a lower prevalence of COPD (p=0.01), and longer anesthesia durations (p=0.033). Logistic regression analysis identified the absence of COPD (OR: 0.202; 95% CI: 0.054–0.759) and low platelet levels (OR: 0.995; 95% CI: 0.991–0.999) as independent predictors of excessive bleeding after CABG surgery. Conclusion: The findings indicate that reduced preoperative platelet count and the absence of COPD are significant risk factors for excessive bleeding following CABG. Moreover, these patients exhibited higher rates of postoperative complications and mortality.

Uzundere et al. (2025) conducted a cross-sectional in Coronary Artery Disease requiring CABG (n=242). Absence of COPD vs. Presence of COPD was evaluated on Excessive postoperative bleeding (OR 0.202, 95% CI 0.054-0.759, p=0.018). The absence of COPD (OR 0.202) and lower preoperative platelet counts (OR 0.995) were identified as independent predictors of excessive bleeding following coronary artery bypass grafting surgery.
