Impact of coronary artery bypass grafting in elderly patients Impacto da cirurgia de revascularização do miocárdio em pacientes idosos

Abstract

OBJECTIVE: To analyze the results of isolated on-pump coronary artery bypass graft surgery (CABG) in patients > 65 years-old. METHODS: Patients undergoing isolated on-pump CABG from December 1st 2010 to July 31th 2012 were divided in two groups: GE (elderly > 65 years-old, n=103) and GA (adults 65-year-old was associated with greater morbidity, but it was not independent predictive factor for in-hospital mortality. Considering in-hospital mortality, stay in ward time length (P=0.006), cardiac (P=0.011) and respiratory complications (P=0.026) were independent predictive factors. CONCLUSION: This study suggests that patients > 65-year old were at increased risk of postoperative complications when submitted to isolated on-pump CABG in comparison to patients OBJETIVO: Analisar os desfechos da cirurgia de revascularização do miocárdio (CRM) isolada com circulação extracorpórea em pacientes com idade > 65 anos em comparação àqueles com 65 anos) e GA (adultos 65 anos não foi um fator preditor de risco associada a variável óbito. CONCLUSÃO: Este estudo sugere que pacientes com idade igual ou superior a 65 anos possuem um maior risco de complicações intra-hospitalares no pós-operatório de CRM isolada com CEC em comparação com pacientes mais jovens.
