Summary

This study tests whether adding a balloon pump (IABP) to standard ECMO support helps the heart recover better in people with severe cardiogenic shock. About 104 adults will be randomly assigned to get ECMO alone or ECMO plus the balloon pump. Researchers will measure heart function and fluid buildup over five days to see if the extra device makes a difference.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
intra-aortic balloon pump (IABP)
What this could lead to
If it works, this could show that adding a balloon pump to VA ECMO helps the heart recover better in people with severe cardiogenic shock.
What could go wrong
This is a Phase 2 trial with only 104 participants, so results are preliminary. The intervention may not improve outcomes and carries risks like bleeding or infection.
