The Usage Of IABP In Cardiogenic Shock Complicating Acute Myocardial Infarction-a Meta Analysis

Aim： In current situation, intraaortic balloon conterpulsation isconsidered to be a class I treatment for cardiogenic shock complicatingacute myocardial infarction, but the usefulness is controversial.This metaanalysis is conducted to access the impact of IABP on this issue.Methods：Database including Embase and Pubmed were searchedusing “cardiogenic shock”、“myocardial infarction”、“IABP”and theirsynonym as the terms. According to the inclusion and exclusioncriteria,data of the included studies were extracted.Then meta-analysis wasperformed using Stata12.0.Results：1168studies were retrieved, and6studies were includedeventually,4prospective controlled trials included2689patients commenton the in-hospital mortality, calculated risk ratios(RR)between the twogroups of patient is1.080,95%CI(0.780,1.497);4prospective controlledtrials included915patients access the30days mortality, calculated RR is0.969,95%CI(0.641,1.466).No significant differences in the RR of the twogroups. Conclusions：The results suggest that IABP support does not result inreduced in-hospital and30days mortality. Because the data is extractedfrom prospective not random controlled trails, a big multi-centerprospective random controlled trail should be conducted.
