Meta Analysis Of Randomized Controlled Trials Comparing MECC With OPCAB

Objective:Use the way of Meta-analysis to compare MECC with OPCAB for treatment outcomes of coronary heart disease.Methods:Comprehensive search strategies were developed using the following databases:Pub Med, EMBASE, Cochrane, Ovid, Google academic, Wanfang, CNKI and VIP. The Literature published before October of 2014.Resluts:After screening, 8 literatures were finally found for Meta analysis. There are 3 papers comparing difference about mortality between MECC and OPCAB,(OR=0.84, 95%CI(0.23,3.05), P=0.80). There are 2 papers comparing the difference about incidence of vascular events between the groups of MECC and OPCAB,(OR=3.35, 95%CI(0.34,32.64),P=0.30). There are 3 papers comparing the difference about incidence of postoperative atrial fibrillation between the groups of MECC and OPCAB(OR=1.30, 95%CI(0.73, 2.32),P=0.37). There are 4 papers comparing the difference about hospitalization time between the groups of MECC and OPCAB(WMD=-0.21,95%CI(-0.78,0.35), P=0.46). There are 5papers comparing the difference about ICU residence time postoperative between the groups of MECC and OPCAB. The ICU residence time postoperative of group about MECC is longer than group about OPCAB(WMD=1.50, P=0.0004,95%CI(0.66,2.33).There are 6 papers comparing the difference about amount of bleeding operation between the groups of MECC and OPCAB,(WMD=41.63, 95%CI(-4.01, 87.27), P=0.07). There are5 papers comparing the difference about postoperative blood transfusion rate,(OR=0.94,95%CI(0.69, 1.35), P=0.83).Conclusion:The Meta analysis showed that:The ICU stay time after MECC is longer than the ICUstay time after OPCAB.
