Impacto da cirurgia de revascularização do miocárdio na cessação do tabagismoImpact of coronary artery bypass graft surgery in smoking cessation Abstract Background: Tobacco use is an important modifiable risk factor for cardiovascular disease. Few studies have investigated the frequency of smoking cessation among patients submitted to heart surgery.Objective: To determine the frequency of smoking cessation in patients submitted to coronary artery bypass graft surgery.Methods: In this cohort study, 203 consecutive patients, aged above 18, submitted to coronary artery bypass graft surgery in the period from January 2006 to March 2007, were interviewed in relation to the use of cigarettes in the pre-and postoperative period. Smokers were stratified according to the levels of nicotine dependence with the use of Fagerström Nicotine Dependence Test. They were followed as outpatients during 60 and 90 days for the occurrence of smoking.Results: The mean age of the group was 62 ± 10 years, and 134 (66%) were male. 80PIETROBON, RC ET AL-Impact of coronary artery bypass graft surgery in smoking cessation Bras Cir Cardiovasc 2010; 25(1): 79-84 Rev

objectIve. To compare the Cleveland Clinical Score and EuroSCORE when evaluating patients submitted to elective CABGS in Rio Grande do Sul, RS, Brazil. Methods. This was a cohort study of 202 patients given CABGS between January 2006 and March 2007. Surgical risk was categorized according to the Cleveland Clinic Score and the EuroSCORE as low, medium or high. The incidence of deaths was measured over a 60-day period. results. The mean age of patients was 62±10 years and 134 (66%) of them were men. A correlation was observed between the scores for classifying patients into different levels of risk. According to the Cleveland Clinic score and the EuroSCORE, respectively, patients were categorized as follows: 142(70.3%) and 155(76.7%) low risk patients, 56(27.7%) and 43(21.3) intermediate risk patients and 4(2%) and 4(2%) high risk patients; with a Kaplan correlation coefficient of 0.432; p0.001. Thirteen (13, 6.4%) patients died during the first 60 days after surgery. There was a correlation between greater incidence of death and higher risk categories for both the Cleveland Clinic score and the EuroSCORE. Deaths occurred in the Cleveland and EuroSCORE risk groups, respectively, as follows: 6 (4.4%) and 7 (4.5%) in the low risk group; 5 (8.9%) and 5 (11.6%) in the intermediate risk group and 2 (50%) 3 1(25%) in the high risk group. Observed sensitivity for surgical mortality prediction was 72.5% and 66.5% for the Cleveland score and EuroSCORE respectively. conclusIon. The Cleveland Clinic and EuroSCORE surgical risk prediction instruments are both moderately effective for predicting mortality among elective CABGS patients.
