Why the study?
Surgical site infections remain a serious complication after CABG, and the study aimed to determine their incidence and identify associated factors in patients at intermediate to high risk.
Are obesity and prolonged hospital stay associated with surgical site infections in intermediate- to high-risk patients undergoing CABG?
Population
51 intermediate- to high-risk patients undergoing CABG via median sternotomy
Comparison
Patients developing surgical site infections vs those who did not
Design
Single-center observational study
Key result
Obesity and prolonged hospital stay were significantly associated with a higher incidence of surgical site infections (33.3% overall rate) in intermediate- to high-risk patients after CABG.

Supports heightened SSI vigilance in obese CABG patients with extended stays; hypothesis-generating and should not yet change practice.

Are obesity and prolonged hospital stay associated with surgical site infections in intermediate- to high-risk patients undergoing CABG?
Effect estimate: ρ = 0.512 for hospital stay; f = 0.348 for obesity
p-value: p=<0.001 for hospital stay; 0.013 for obesity
In intermediate- to high-risk patients undergoing CABG, obesity and prolonged hospital stay are significantly associated with a higher incidence of surgical site infections.
Kyriazi et al. (2025) conducted an observational in Coronary artery disease undergoing CABG (n=51). Obesity and prolonged hospital stay vs. Non-obese and shorter hospital stay was evaluated on Incidence of surgical site infections (SSIs) (ρ = 0.512 for hospital stay; f = 0.348 for obesity, p=<0.001 for hospital stay; 0.013 for obesity). Obesity and prolonged hospital stay were significantly associated with a higher incidence of surgical site infections (33.3% overall rate) in intermediate- to high-risk patients after CABG.
