Inclusion criteria

Inclusion criteria: 1. Patients who underwent OPCAB surgery under general anesthesia 2. Patients who underwent mixed venous oxygen saturation monitoring and peripheral oxygen saturation monitoring through a pulmonary artery catheter during surgery 3. Patients who underwent brain tissue oxygen saturation monitoring through near-infrared spectroscopy during surgery

Exclusion criteria

Exclusion criteria: Patients were excluded if their vital records did not include SvO2 and NIRS; if intraoperative central venous pressure wave form or postoperative chest radiography showed a mal-positioned pulmonary artery catheter; if SvO2 signal showed a persistent poor signal quality index (SQI=4); or if a mechanical circulatory assist device was used
