Características clínico-demográficas de pacientes submetidos à cirurgia de revascularização do miocárdio e sua relação com a mortalidadeDemographic and clinical characteristics of patients undergoing coronary artery bypass graft surgery and their relation to mortality Abstract Objective: To describe the demographic and clinical characteristics of patients undergoing coronary artery bypass graft surgery (CABG) and to test their relation to mortality. Methods: This study was a retrospective medical record review of 655 consecutive patients undergoing CABG from May 2002 to April 2010. Results: Of the 655 patients, 12.1% died during the hospital stay. Mortality was significantly (p<0.05) higher in females (17.3%), aged < 70 years (22.8%), in emergency surgery (36.4%), in cases of readmission to the intensive care unit (ICU) (33.3%), when the stay in the ICU was < three days (16.3%), undergoing longer cardiopulmonary bypass (CPB), and with more comorbidities (15.4%). Predictor variables of death identified with logistical regression analysis were: female (OR=2.04), age > 70 years (OR=2.69), emergency surgery (OR=15.43) and urgency (OR=3.81), performance of CPB (OR=2.19) and readmission to the ICU (OR=4.33). Conclusion: Variables such as female sex, increased age, type of surgery, readmission to the ICU, ICU stay, comorbidities, and duration of CPB influence the outcome death in patients undergoing CABG. Thus, such aspects should be considered to reduce hospital mortality in patients undergoing such surgery.

Resumo Objetivo: Descrever as características clínicodemográficas e testar sua relação com a mortalidade hospitalar em pacientes submetidos à cirurgia de revascularização do miocárdio (CRM).Métodos: Estudo retrospectivo conduzido a partir dos prontuários de 655 pacientes submetidos à CRM, no período de maio de 2002 a abril de 2010.Resultados: A mortalidade hospitalar foi de 12,1%. A mortalidade foi significativamente (P<0,05) maior em indivíduos do sexo feminino (17,3%), com idade igual ou superior a 70 anos (22,8%), em cirurgias de emergência (36,4%), nos casos de reinternação na unidade de terapia intensiva (UTI) (33,3%), quando a permanência foi inferior a três dias na UTI (16,3%), submetidos a maior tempo de RBCCV 44205-1350 Oliveira EL, et al. -Demographic and clinical characteristics of patients undergoing coronary artery bypass graft surgery and their relation to mortality Rev Bras Cir Cardiovasc 2012;27(1):52-60
