Key result
Myocardial revascularization surgery at a public referral hospital in the Brazilian Amazon had an 11.7% 30-day mortality rate, with waiting time ≥30 days, infection, and hemodialysis as predictors.
Why the study?
Data on mortality rates among patients undergoing myocardial revascularization surgery in hospitals outside main referral centers in northern Brazil are scarce.

What are the clinical outcomes and predictors of mortality in patients undergoing myocardial revascularization surgery in a public cardiology referral hospital in the Brazilian Amazon?
The study highlights a high 30-day mortality rate (11.7%) following myocardial revascularization surgery in a public hospital in the Brazilian Amazon, driven by factors such as prolonged waiting times and postoperative complications.

Initial regional MRS outcome data in northern Brazil; leaves open need for prospective studies before informing practice.
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.

Lobato et al. (2018) conducted a cohort in Myocardial revascularization surgery (n=179). Myocardial revascularization surgery was evaluated on Mortality until 30 days after surgery. Myocardial revascularization surgery at a public referral hospital in the Brazilian Amazon had an 11.7% 30-day mortality rate, with waiting time ≥30 days, infection, and hemodialysis as predictors.
