At the Heart Institute, we performed a study to evaluate if the internal thoracic artery modified the nosocomial mortality of elderly coronary patients (age 70 years), submitted to elective isolated revascularization of the myocardium. Clinical, hemodynamic, radiologic, operative and postoperative parameters were included in the protocol. In a prospective study one hundred consecutive patients, with complete observations were analysed. The statistical analysis was performed using Pearson's X 2 test. The results of this study showed that there was a statistically significant difference between the groups, the nosocomial mortality being higher in that in which autogenous saphenous vein grafts were used. The role of the surgeon as a screener regarding obtention of results is also discussed.


No InCor, foi elaborado um protocolo para avaliar se o emprego da artéria torácica interna alterava a mortalidade hospitalar nos pacientes coronarianos idosos (idade > 70 anos), submetidos a revascularizaçáo isolada, eletiva do miocárdio. No protocolo foram incluídos parâmetros clínicos, hemodinâmicos, radiológicos, operatórios e de pós-operatório. Foram analisados 100 pacientes consecutivos, com observações completas, em estudo prospectivo. A análise estatística foi realizada pelo teste de X2 de Pearson. Concluímos que houve diferença estatística entre os grupos comparados e que a mortalidade hospitalar foi maior no grupo de pacientes nos quais se utilizou o enxerto de veia safena autógena. Atribuiu-se ao cirurgião, como triador, a obtenção de tais resultados, utilizando a artéria torácica interna naqueles pacientes em melhor estado geral.
