Abstract
Purpose
To investigate the prevalence of obstructive sleep apnea hypopnea syndrome (OSAHS) in patients undergoing off-pump coronary artery bypass grafting (OPCABG) and analyze the effects of OSAHS on the incidence of post-OPCABG complications, length of stay in intensive care unit (ICU) and hospitalization, and hospital expense.
Materials and methods
This prospective study included patients undergoing OPCABG at Beijing An Zhen hospital from January 2018 to December 2018. OSAHS was diagnosed by using a portable sleep monitor before surgery.
Results
Among 74 patients, the prevalence of OSAHS and moderate to severe OSAHS (apnea hypopnea index (AHI) ≥ 15) was 70% and 53%, respectively. Compared with the no to mild OSAHS group (AHI < 15), the moderate to severe OSAHS group presented a lower ejection fraction (P = 0.013). Between these two groups, the incidence of post-OPCABG complications; the duration of intubation, ICU stay, and hospitalization; and the hospital expense did not differ. Notably, the ejection fraction was significantly negatively correlated with the duration of ICU stay and hospital expense.
Conclusions
Patients undergoing OPCABG with severe OSAHS are likely to exhibit a low ejection fraction and poor heart function, which may require a longer ICU stay and incur higher hospital expenses.
