Abstract

OBJETIVO: Permanecem as controvérsias sobre a utilização de circulação extracorpórea (CEC) na cirurgia de revascularização miocárdica (CRM). O objetivo deste estudo foi avaliar o impacto do 2000 Bernstein Parsonnet (2000BP) e EuroSCORE (EU) para escolha de CEC na CRM. MÉTODOS: Foram submetidos à CRM 1.551 pacientes consecutivos. CEC foi utilizada em 1.121 (72,3%) pacientes. O desempenho do 2000BP e EU para a amostra foi avaliado mediante testes de calibração, discriminação e correlação. Para ambos os escores de risco, o aumento do valor do escore e a presença de CEC tiveram relação direta com maior chance de óbito (P17,75, a presença de CEC aumentou a chance de óbito para 7,4 [IC95% (4,4-12,3), P4,5, a presença de CEC aumentou a chance de óbito para 5,4 [IC95% (3,3-9), P17,75 ou o EU>4,5 orientam a identificar pacientes que quando submetidos a CRM com CEC têm chance de óbito aumentada significativamente. OBJECTIVE: Remain controversies about the use of cardiopulmonary bypass (CPB) in coronary artery bypass grafting (CABG). The aim of this study was to evaluate the impact of the 2000 Bernstein Parsonnet (2000BP) and EuroSCORE (EU) for choice CPB in CABG. METHODS: 1.551 consecutive patients underwent CABG. CPB was used in 1.121 (72.3%) patients. The performance of 2000BP and EU was assessed by calibration, discrimination and correlation tests. For both risk scores, increasing the value of the score and presence of CPB were directly related to a higher risk of death (P17.75 the presence of CPB increased the chance of death to 7.4 [CI 95% (4.4-12.3), P4.5 the presence of CPB increased the chance of death to 5.4 [CI 95% (3.3-9), P17.75 or the EU>4.5 guide to identify patients who underwent CABG with CPB increases significantly the chance of death.
