Abstract

Background: We sought to assess the effect of smoking on early outcome following valve surgery. Methods: This is a retrospective review of a prospectively collected departmental database of all patients who underwent isolated aortic and/or mitral valve surgery (replacement and/or repair). Our cohort consisted of 590 patients stratified into three groups: current smokers (n = 94), ex-smokers (n = 243), and nonsmokers (n = 253). Results: There were no significant differences in the in-hospital mortality between the three groups. Likewise, the length of both hospital and intensive care unit stays were similar among the three groups with a similar rate of postoperative complications. These findings remained statistically not significant, even after adjusting for potential confounders such as age, gender, etc. Conclusion: Smoking does not seem to be associated with an increased early postoperative risk in patients undergoing valve surgery. However, because of the known effect of smoking on the risk of cardiovascular disease and because the effect of smoking on long-term survival in patients undergoing valve surgery remains unknown, patients should still be encouraged to quit smoking.
