Objective: Coronary artery bypass graft (CABG) is a major surgery conducted in coronary heart disease management. Postoperative recovery is a crucial process for patients undergoing CABG. This systematic review evaluates current evidence regarding the association between trait optimism and recovery outcomes in patients following coronary artery bypass graft surgery. Methods: This review followed the Preferred Reporting Items of Systematic Review and Meta-Analysis (PRISMA) 2020 Guideline. The inclusion criteria focused on observational study that examined study participants aged ≥18 years old undergoing elective CABG and measurement of trait optimism with validated methods (i.e. LOT, LOT-R) and at least one recovery outcome. Studies in non-English languages and duplicates were excluded. A systematic literature search was carried out on PubMed, Scopus, and Web of Science electronic databases. Search results were screened based on the eligibility criteria. The Newcastle-Ottawa Scale was used to assess the quality of each included study. Results: The search yielded a total of 1853 articles, in which 7 articles fulfilled the eligibility criteria and were subsequently included in the analysis. Measurement of trait optimism was conducted on 1276 patients who underwent a non-emergency/elective CABG. Optimism was significantly associated with several categories of recovery, including reduced rehospitalization rate, complications, pain, and physical symptoms along with improved quality of life, rate of return to normal life, and psychological status. Conclusion: Our review showed that trait optimism was associated with recovery outcomes following CABG surgery. However, the heterogeneity of recovery outcomes may hamper the clinical benefit of trait optimism in CABG. (PROSPERO CRD42022301882).
