Insights
Patients with chronic obstructive pulmonary disease (COPD) undergoing off-pump coronary artery bypass graft (CABG) surgery experience similar mortality and morbidity rates compared to those without COPD. This suggests COPD presence does not significantly impact outcomes after off-pump CABG.
Area of Science:
- Cardiovascular Surgery
- Pulmonary Medicine
- Critical Care Medicine
Background:
- Chronic obstructive pulmonary disease (COPD) is a significant comorbidity affecting cardiovascular health.
- Off-pump coronary artery bypass graft (CABG) surgery is a common procedure for coronary artery disease.
- The impact of COPD on outcomes following off-pump CABG requires further elucidation.
Purpose of the Study:
- To investigate the influence of chronic obstructive pulmonary disease (COPD) on mortality and morbidity in patients undergoing off-pump coronary artery bypass graft (CABG).
Main Methods:
- A cohort study involving 321 patients undergoing off-pump CABG.
- Patients were divided into two groups: 46 with COPD (Group 1) and 275 without COPD (Group 2).
- Comparative analysis of preoperative data, intraoperative parameters, and postoperative outcomes between the two groups.
Main Results:
- Group 1 (COPD) exhibited lower preoperative oxygen saturation and higher carbon dioxide levels.
- Patients with COPD showed increased requirements for prolonged intubation, pulmonary complications, and medication use (bronchodilators, steroids).
- No significant difference in overall mortality incidence was observed between the COPD and non-COPD groups.
Conclusions:
- Off-pump CABG can be performed with similar in-hospital mortality and severe morbidity rates in patients with and without COPD.
- The presence of COPD does not appear to be a significant risk factor for adverse outcomes post-off-pump CABG.
- These findings support the safety of off-pump CABG in selected COPD patients.
Purpose:
To determine to what extent chronic obstructive pulmonary disease (COPD) affects mortality and morbidity rates in patients treated with off-pump coronary artery bypass graft (CABG).
Methods:
A total of 321 patients treated with off-pump CABG were included in the present study. Of the 321 patients, 46 patients had COPD and they were designated as Group 1 and the remaining 275 patients did not have COPD and they were considered as Group 2. We compared the data obtained from the patients in both groups.
Results:
While preoperative spirometry values and arterial blood gas oxygen saturation levels were significantly lower, the partial values of carbon dioxide were higher in Group 1. Likewise, extubation time, the amount of drainage and blood transfusion, inotropic support, prolonged intubation, pulmonary complications, the use of bronchodilators, and steroids were statistically higher in Group 1 when compared with Group 2. Overall, there was no marked difference between the two groups in terms of mortality incidence.
Conclusion:
We found similar morbidity and mortality rates among the patients with COPD and without COPD when they were treated with off-pump CABG. Therefore, the present results indicate that the presence of COPD is not associated with in-hospital mortality or severe morbidity post-CABG by off-pump approach.

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
