RESUMO
Fundamentos A prevalência de doenças cardiovasculares é muito alta e cirurgias cardíacas são comuns em centros terciários de atenção cardiovascular.

Objetivo:

Avaliar a mortalidade cirúrgica e comparar com a mortalidade esperada pelo EuroSCORE em pacientesde centro terciário de atenção cardiovascular.

Métodos:

Trata-se de coorte histórica que avaliou pacientes submetidos a cirurgias cardíacas em 2011 e 2012, emhospital terciário de referência em cardiologia no sul do Brasil. O desfecho principal foi a mortalidade por qualquer causa durante a internação hospitalar. Os desfechos secundários foram a mortalidade de acordo com o procedimento cirúrgico, o EuroSCORE total e de acordo com o procedimento, a mortalidade ajustada por EuroSCORE e o perfil de risco dos pacientes.

Resultados:

Foram incluídos 364 pacientes. Cirurgia de revascularização do miocárdio (CRM) isolada foi oprocedimento realizado em 59,9% dos pacientes, o procedimento valvar (PV) isolado (troca ou plastia valvar) em33,0% e a CRM + PV em 7,1% dos pacientes. A mortalidade observada foi 14,2%, sendo 5,2% nas primeiras 24 horas. A mortalidade esperada pelo EuroSCORE, por sua vez, foi 5,7±7,4%. A mortalidade ajustada foi, assim, 2,5 vezes superior à esperada, mas dentro do intervalo de dois desvios-padrão da mortalidade esperada. A mortalidade associada aos procedimentos combinados, entretanto, foi 5,2 vezes superior a do EuroSCORE esperado e superior ao intervalo de dois desvios-padrão do EuroSCORE.

Conclusão:

Pacientes submetidos à cirurgia cardíaca no centro estudado apresentaram mortalidade superior à esperada, em especial aqueles submetidos a procedimentos combinados.
ABSTRACT

Background:

The prevalence of cardiovascular diseases is very high and cardiac surgeries are common in tertiary centers for cardiovascular care.

Objective:

Evaluate the surgical mortality and compare the mortality level expected by EuroSCORE in patients from tertiary centers for cardiovascular care.

Methods:

Historical cohort study evaluating patients who have under gone cardiac surgeries in 2011 and 2012, at a renowned tertiary cardiology hospital in southern Brazil. The primary outcome was all-cause mortality during hospitalization. Secondary outcomes were surgery-related mortality, total and procedure-related EuroSCOREs, the adjusted mortality rate by EuroSCORE and the risk profile of patients.

Results:

The study comprised 364 patients. Coronary artery bypass graft (CABG) surgery alone was the procedure performed in 59.9% of patients, followed by the valve procedure (VP) (valve replacement or repair) in 33.0%, and CABG + VP in 7.1% of patients. The mortality rate was 14.2%, with 5.2% in the first 24 hours. The mortality rate expected by EuroSCORE, in turn, was 5.7 ± 7.4%. The adjusted mortality rate was thus 2.5 times higher than the expected, however within the range of two standard deviations of the expected mortality rate. Mortality associated with combined procedures, however, was 5.2 times higher than theEuroSCORE expected, and higher than the range of two standard deviations of EuroSCORE.

Conclusion:

Patients undergoing cardiac surgery at the center under study showed higher mortality than the expected rate, especially those undergoing combined procedures.
