What is the role of intra-aortic balloon counterpulsation in acute myocardial infarction presenting without shock?

Mortality at six months was numerically lower in the group treated with IABP during the index PPCI procedure but this difference did not reach statistical significance, likely being a consequence of the relatively small number of events [1.9% (n=3) IABP+PCI vs 5.2% (n=9) SOC, P=0.12].
