Association of Low Skeletal Muscle Mass and Low Skeletal Muscle Radiodensity With Postoperative Delirium in Patients Undergoing Off-Pump Coronary Artery Bypass Grafting: A Retrospective Cohort Study
Authors' conclusion
Among patients undergoing OPCABG, low SMI and low SMD were independently connected to POD. Additionally, the highest risk of POD was observed in patients with both low SMI and low SMD.
Study context
- Population
- Adults undergoing off-pump CABG (off-pump coronary artery bypass grafting (OPCABG)), university-affiliated hospital, January–December 2021
- Participants
- 228 adults
- Exposure
- Low vs higher skeletal muscle index (SMI) and radiodensity (SMD) on preoperative CT at L3
- Outcome
- POD
Methodological detailssingle-center, retrospective observational, Low SMI/SMD = lowest sex-specific tertile
- Single-center
- Retrospective observational
- Low SMI/SMD = lowest sex-specific tertile
Main finding
As reported in the abstract
Odds ratio (95% CI)
SMI (continuous)
0.95(0.90–0.999)
SMD (continuous)
0.93(0.87–0.99)
- Patients who developed postoperative delirium (POD)
- 54 (23.7%)
Observational data: associations, not effects.
