💬In plain words
What the trial is, and whether it could suit you
The ULYSS study is a randomized, multicenter, interventional and prospective open-label clinical trial. It aims to evaluate the efficacy of the addition of an early IMPELLA CP support on top of optimal medical therapy and culprit lesion PCI compared to optimal medical care and culprit PCI in patients with an ACS complicated by a CS.
A transthoracic echography is required to exclude some non-inclusion criteria as soon as possible and before randomization.
Randomization will be performed after an informed consent is signed by the patient, a family member if he is unable to consent or thanks to the emergent consent procedure if all inclusion criteria are met and there are no non-inclusion criteria. A computer-generated randomization list will be drawn-up using a permuted block design (stratified on center). Each center will have a specific list.
Randomization 1:1 to one of the 2 groups
