Resumo

Objective: To determine the risk factors related to the development of stroke in patients undergoing cardiac surgery.Methods: A historical cohort study.We included 4626 patients aged ≥ 18 years who underwent coronary artery bypass surgery, heart valve replacement surgery alone or heart valve surgery combined with coronary artery bypass grafting between January 1996 and December 2011.The relationship between risk predictors and stroke was assessed by logistic regression model with a significance level of 0.05.Results: The incidence of stroke was 3% in the overall sample.After logistic regression, the following risk predictors for stroke were found: age 50-65 years (OR=2.11-95% CI 1.05-4.23 -P=0.036) and age ≥66 years (OR=3.22-95% CI 1.6-6.47-P=0.001),urgent and emergency surgery (OR=2.03-95% CI 1.20-3.45-P=0.008),aortic valve disease (OR=2.32-95% CI 1.18-4.56-P=0.014),history of atrial fibrillation (OR=1.88-95% CI 1.05-3.34-P=0.032),peripheral artery disease (OR=1.81-95% CI 1.13-2.92-P=0.014),history of cerebrovascular disease (OR=3.42-95% CI 2.19-5.35-P 110 minutes (OR=1.71-95% CI 1.16-2.53-P=0.007).Mortality was 31.9% in the stroke group and 8.5% in the control group (OR=5.06-95% CI 3.5-7.33-P 110 minutes.
