Impact of transient decrease in mixed venous oxygen saturation on prognosis in off-pump coronary artery bypass surgery: a retrospective cohort study.

ABSTRACT:

Background

The prognostic consequences of transient hemodynamic deterioration due to cardiac displacement, which is most severe during left circumflex artery (LCX) grafting in off-pump coronary artery bypass surgery (OPCAB) are unknown. This study aimed to investigate the association between mixed venous oxygen saturation (SvO2) < 60% during LCX grafting and the occurrence of composite of morbidity endpoints.

Methods

Data of patients who underwent elective OPCAB between January 2010 and December 2019 were reviewed. Logistic regression analysis was performed to detect risk factors for the composite of morbidity endpoints, defined as 30-day or in-hospital mortality, postoperative myocardial infarction, prolonged mechanical ventilation > 24 h, cerebrovascular accident, and acut
