  "abstract": "BackgroundSurgical site infection (SSI) in patients with frailty undergoing myocardial revascularization is a major clinical challenge, and there is a gap in the literature related to this topic. ObjectiveThis study aimed to identify perioperative variables associated with SSI in patients with frailty and prefrailty undergoing coronary artery bypass grafting within 30 days of the procedure. MethodsThis retrospective observational study included 467 patients with frailty or prefrailty aged 60 years and older who underwent coronary artery bypass grafting in 6 Brazilian centers between January 2018 and December 2024. Frailty was defined using the Fried criteria. SSI was defined as a wound with exposed tissue with positive culture requiring antibiotic treatment. Univariate and multivariate analyses were carried out. ResultsThe rate of SSI was 5.6% (26/467). The New York Heart Association classification (PPPPPPPPPPPP ConclusionsThe CCI and the use of CPB were independently associated with SSI.",
