Abstract Background Reducing hospital readmissions following coronary artery bypass grafting (CABG) surgeries is essential to optimizing medium- and long-term patient outcomes. Objective To analyze preoperative predictors associated with all-cause cardiac within 5 years CABG. Methods We analyzed 1,387 patients who underwent CABG between June 2017 July 2019 using data from the multicenter REPLICCAR II registry. Follow-up was carried out by telephone interviews a questionnaire structured in REDCap platform. Statistical analysis included univariate multivariate methods, Cox regression internal validation through calibration discrimination tests. A significance level of 5% applied. Results The cumulative incidence readmission 27.69%, mean follow-up 4.3 time 2.4 years. Multivariate indicated higher risk: lower body mass index (HR=0.97, p=0.032), history myocardial infarction (HR=1.27, p=0.024), diabetes mellitus (HR=1.35, p=0.004), renal failure (HR=1.62, STS score (HR=1.22, p<0.001). moderate correlation observed mortality (Rho=0.55). Conclusions This demonstrates that index, infarction, mellitus, failure, elevated scores are significant increased risk
