Improvement of hemodynamic parameters is the rationale for the use of intra-aortic balloon pump counterpulsation (IABP) in patients with cardiogenic shock following acute myocardial infarction (MI). This Cochrane systematic review evaluated the impact of this intervention in reducing mortality. Seven randomized controlled trials with a total of 790 patients were included (four using medical therapy as a comparator, and three comparing IABP with other ventricular assist devices). IABP did not reduce mortality in either the short or long term. Therefore, the systematic use of IABP in patients with cardiogenic shock following MI cannot be recommended.
