Is coronary artery by pass surgery a risk for cerebrovascular accidents in smokers?

Objective: This study aimed to reveal that how often smoker patients with coronary bypass surgery are exposed to cerebrovascular events compared to nonsmokers. Methods: In our clinic between December 2011 and September 2013, 100 patients with coronary artery bypass surgery were included in the study. First, patients were divided into two groups: Group 1 (n = 20) smokers and Group 2 (n = 80) non-smokers. Postoperative CVA risk assessments of these patients were done according to the American Heart Association (ACC / AHA) criteria. Results: The patients evaluated were 73 male and 27 female. In the smokers group 1 person, in the non-smokers group 2 people had CVA. There were no significant differences between the two groups (p> 0.05). There were no significant differences for intraoperative cardiopulmonary bypass and aortic cross-clamp time between the two groups (p> 0.05). Carotid in tima and media thickness (CIMT) in the group of smokers show a significant difference compared to non smokers (p <0.05). Conclusion: When postoperative evaluation between the two groups, in non-smokers group in two patients CVA has been diagnosed (2.5%); in smokers group in one patient CVA has been diagnosed (5%). Although the incidence of CVA was not significantly different, CIMT showed a significant difference in smoking patients compared to non-smokers(p <0.05).
