Background: Myocardial revascularization surgery (MRS) is the most frequently performed cardiac surgery in Brazil. However, data on mortality rates among patients undergoing MRS in hospitals other than the main referral centers in the northern Brazil are scarce.

Objective: To describe the clinical course of patients that submitted to MRS in the major public cardiology referral hospital in the Brazilian Amazon.

Methods: Retrospective cohort analysis, by review of medical records of patients who had undergone MRS at Hospital das Clínicas Gaspar Vianna (FHCGV) from January 2013 to June 2014.

Results: A total of 179 patients were evaluated. Mortality rate was 11.7% until 30 days after surgery. Waiting time for surgery ≥ 30 days (OR 2.59, 95%CI 1.02 – 6.56, p = 0.039), infection during hospitalization (OR 3.28, 95%CI 1.15 – 9.39, p = 0.021) and need for hemodialysis after surgery (OR 9.06 95%CI 2.07 – 39.54, p = 0.001) were predictors of mortality after CABG.

Conclusion: A high mortality rate in the study population was found, higher than that reported in the literature and in other regions of Brazil. (Int J Cardiovasc Sci. 2019;32(3)217-226)
