Abstract
OBJECTIVES: This meta-analysis aims to assess the graft patency quantitatively and statistically. METHODS: Eleven observational studies were identified by systematic literature search, incorporating 3311 patients undergoing coronary endarterectomy (CE) + coronary artery bypass graft (CABG) and 3990 undergoing isolated CABG, which were analysed using random-effects modelling. Heterogeneity, quality of scoring and risk of bias were assessed and reangiographic outcomes were documented. RESULTS: Adjunctive CE decreased graft patency [odds ratios = 0.43, 95% confidence interval [0.29-0.63], z = 4.33, P < 0.0001] with moderate heterogeneity, while the baseline demographics differed considerably. CONCLUSIONS: Whether CE remains a viable option to CABG requires novel studies collecting corresponding data from bench to bedside. To achieve satisfactory efficacy, surgeons should carefully weigh possible benefits and adverse effects of CE and prepare the surgical strategy adequately.
