Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older diagnosed with acute cardiogenic shock who are failing medical therapy.

Probably not a fit

Patients with metastatic cancer, planned LV unloading on ECMO, or those who are pregnant may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to evaluate the effects of adding left ventricular unloading to veno-arterial extracorporeal membrane oxygenation (VA ECMO) in patients experiencing cardiogenic shock. Participants will be randomized to receive either standard VA ECMO or VA ECMO combined with an intra-aortic balloon pump (IABP) for LV unloading. The study will assess physiological changes, myocardial function, and recovery outcomes through various measurements, including lab work and echocardiography. The goal is to determine if LV unloading improves patient outcomes compared to VA ECMO alone.

Why it matters

Potential benefit: If successful, this approach could enhance recovery and survival rates in patients with cardiogenic shock.

How similar studies have gone: Preliminary data suggests that LV unloading may improve survival in similar patient populations, indicating potential success for this approach.
