Desfechos clínicos pós-revascularização do miocárdio no paciente idoso
Outcomes after coronary artery bypass in aged patientsWork performed at the Heart Institute, Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, São Paulo, SP, Brazil. Results: We analyzed 290 patients that possessed appropriate information. The first group G1, of the patients operated without CPB consisted of 111 patients and the second group G2, of the operated ones with CPB consisted of 179 patients. The univariated analysis presented statistics significance for the variables: cardiac insufficiency functional class preoperative (P=0.000), tobacco smoking (P=0.050), number of performed grafts (P=0.050), graft type (P=0.000), associated procedures (P=0.000), preoperative use of intra-aortic balloon (P=0.000), hospital mortality (P=0.000) and type of death (P=0.020). In the postoperative outcomes it was significant only the incidence of brain stroke (CVA) in G2 (P=0.036). In the long term there was higher incidence of reinternment for angina (P=0,038). The analysis of the survival curves presented statistic difference (P=0.009; LogRank Test).Conclusions: CABG without CPB, in this series, proved to be beneficial for the octogenarian patients in the short term, due to the patients having presented lower incidence of brain stroke in the immediate postoperative, whereas in the long term there was higher incidence of re-internments for angina in G1 and higher prevalence of cardiac deaths in G2. Resultados: Na análise univariada apresentaram significância: insuficiência cardíaca congestiva pré-operatória (P=0,000), tabagismo (P=0,050), número de enxertos realizados (P=0,050), tipo de enxerto (P=0,000), procedimentos associados (P=0,000), uso de balão intraaórtico no pós-operatório (P=0,000), óbito hospitalar (P=0,000) e tipo de morte (P=0,020). No pós-operatório imediato, foi significativa apenas a incidência de acidente
