Abstract:
Objective To systematically review the myocardial protective effect of ischemic preconditioning in patients undergoing open heart surgery.Methods PubMed,EMBASE,Highwire,CENTREN and its affiliated clinical trial registration data center,CBM and CNKI were searched to identify all randomized controlled trials involving the myocardial protective effect of ischemic preconditioning in patients undergoing open heart surgery under general anesthesia.The quality of the studies was evaluated by the method recommended by Cochrane Collaboration.Evaluation indexes included the incidences of postoperative cardiac death,myocardial infarction and ventricular arrhythmias and postoperative inotropic drug requirement.Meta-analysis was conducted using the Cochrane Collaboration's RevMan 5.0 software.Results Twelve randomized controlled trials (8 high-quality trials and 4 medium-quality trials) involving 626 patients were included in our Meta-analysis.Meta-analysis indicated that ischemic proconditioning significantly reduced the incidence of postoperative ventricular arrhythmias and postoperative inotropic drug requirement (P ＜ 0.05) and had no effect on the incidences of postoperative cardiac death and myocardial infarction (P ＞ 0.05).Conclusion Ischemic preconditioning can reduce the postoperative ventricular arrhythmias and have no effect on postoperative cardiac death and myocardial infarction in patients undergoing open heart surgery.
