Introduction: In our study COPD and non-COPD patients who underwent CABG were compared in terms of prolonged mechanical ventilation and lower respiratory tract infektion. Patients and Methods: A total of 233 patients without valvular pathology and connective tissue disorders, such as Marfan syndrome, who underwent isolated on-pump CABG in the Department of Cardiovascular Surgery were retrospectively studied. Preoperative laboratory tests and respiratory system test (Spirobank Spirometry, Medical International Research Product) were applied in patients who had pathology in respiratory system query or examination were performed at our clinic during the preoperative period. The severity of COPD in COPD patients was evaluated according to the COLD guideline. All patients were divided in two groups. The group including COPD patients was named group 1 and the other group including non-COPD patients was named gruop 2. Results: UMSD rates in groups 1 and 2 were 4.8% and 1.8%, respectively. Lower respiratory tract infection rates in groups 1 and 2 were 6.3% and 1.7%, respectively. Conclusion: According to our study, we can say that the rate of UMSB and lower respiratory tract infection occuring in treated COPD patients after CABG is statiscally indifferent according to non-COPD patient. (p= 0.348 for UMSD, p= 0.088 for lower respiratory tract infection).
