FEIER, Flávia Heinz et al. Changes in profile of patients submitted to coronary bypass graft surgery. Rev Bras Cir Cardiovasc [online]. 2005, vol.20, n.3, pp. 317-322. ISSN 1678-9741. http://dx.doi.org/10.1590/S0102-76382005000300014.
INTRODUCTION: The improvement in care and management of ischemic heart disease and the dissemination of percutaneous coronary intervention (PCI) changed the indications for coronary artery bypass grafting (CABG), regarding procedures for patientswith multivessel disease in bad clinical conditions. OBJECTIVE: To compare surgical and clinical profiles between two groups of CABG patients at a 10 year interval observing the influence on hospital mortality rates. METHOD: Retrospective Cohort study, including 307 CABG patients operated on in 1991to 1992 (n=153) and 2001 to 2002 (n=154). Demographic characteristics, heart disease severity, comorbidities and pre-operative events were evaluated and compared between the groups. RESULTS: Patients operated in 2001 and 2002 were older, more severely ill (in a worse NYHA classand had higher prevalence of heart failure, and multi-vessel involvement) and with more co-morbidities. Patients operated in 1991 and 1992 had more urgent procedures. The observed surgical mortality rates were similar (3.3% and 1.9%, respectively). CONCLUSION: Patients submitted to CABG currently are older and in worse clinical conditions than those operated 10 years ago, but hospital mortality has not altered significantly.
