IABP not shown to reduce infarct size

This surprised me a bit.  Having cared for 300+ IABP patients during my career in healthcare I have seen first-hand what the device is capable of.  I really need to read the whole study to see how it was designed. In my personal experience it provides more benefit than just limiting infarct size.  Other benefits include, stabilizing patients in cardiac shock, a bridge to bypass surgery or PCI, cardiac output improvement to get off cardiopulmonary perfusion during cardiac surgery to name some.

Yes it is invasive, and not clinically benign, but it does save lives.
