ObjectiveThe aim of the present study was to assess the influence of preoperative statin therapy on postoperative mortality in high-risk patients after isolated valve surgery.DesignAn observational cohort study.SettingA 1,200-bed university hospital.ParticipantsAll consecutive patients undergoing isolated nonemergent valve surgery with cardiopulmonary bypass between November 2005 and December 2007 were included.InterventionNone.Measurements And Main ResultsDuring the period, 772 consecutive patients underwent nonemergent isolated valve surgery. Among them, 430 were high cardiovascular risk (defined by patients with 2 or more cardiovascular risk factors). In the high-risk cardiovascular patients, statin pretreatment was administered in 222 patients (52%). In multivariate analysis, after adjustment with a propensity score analysis, preoperative statin therapy was associated with a significant reduction of postoperative mortality in patients with high risk (odds ratio = 0.41; 95% confidence interval, 0.17-0.97; p = 0.04). Low left ventricular ejection fraction and elevated pulmonary artery pressure also were independently associated with increased postoperative mortality. By contrast, in the low-risk patient group, few patients received preoperative statin therapy (7%).ConclusionsThis study suggests that preoperative statin therapy may have a potential beneficial effect on postoperative mortality after isolated cardiac valve surgery in high-risk cardiovascular patients.Copyright © 2010 Elsevier Inc.
