ObjectiveThe purpose of this meta-analysis was to assess the role of preoperative statin therapy on adverse cardiovascular events in patients undergoing valve surgery.DesignMeta-analysis of 10 observational studies.SettingHospital.Participants22,158 patients.InterventionsNone.Measurements and Main ResultsThe Medline, Cochrane, and Embase databases were searched for clinical studies published up to June 2014. Studies that evaluated the effects of preoperative statin therapy on valve surgery were included. After a literature search in the major databases, 10 observational studies with 22,518 patients were identified. Pool analysis indicated that preoperative statin therapy was associated with a significantly lower risk of early all-cause mortality (Odds ratio [OR]: 0.69; 95% confidence interval [CI] 0.50-0.95, p = 0.03). The benefits of preoperative statin therapy were more obvious in studies with isolated valve surgery, resulting in a 1.9% absolute risk and a 38% odds reduction of early mortality (2.4 v 4.3%; OR: 0.62; 95% CI 0.49-0.77, p<0.0001). A significant reduction by statin therapy also was observed for atrial fibrillation (OR 0.88, 95% CI: 0.80-0.98, p = 0.02). However, statin therapy was not associated with a lower risk of postoperative stroke (OR: 0.74; 95% CI 0.46-1.19, p = 0.21), myocardial infarction (OR: 1.02; 95% CI 0.78-1.34, p = 0.87), and renal failure (OR: 0.91; 95% CI 0.57-1.44, p = 0.68).ConclusionsPreoperative statin therapy was associated with a significantly lower risk of early mortality in patients undergoing isolated valve surgery. A prospective, randomized, controlled trial is warranted.
