To assess strut coverage in patients presenting an acute myocardial infarction and treated either with the SYNERGY stent or the Bioresorbable Vascular Scaffold, through a parallel group design.

Single center, simple-blind randomized controlled trial, comparing the SYNERGY stent with the BVS device through a parallel group design.

Inclusion Criteria:

• Acute coronary syndrome with ST-elevation,
• One culprit lesion eligible for percutaneous coronary intervention (PCI) with stent implantation,
• Reference vessel measuring 2.5 mm to 3.75 mm per visual estimation, without extreme vessel tortuosity,
• thrombolysis in myocardial infarction (TIMI) 3 flow before stent deployment in the target vessel,
• Patient with at least 1 lesion eligible for planned PCI next to the culprit lesion,
• Patient affiliated to the French national health care system,
• Patient agreed to participate after full information on the study (signature of an informed consent).
