Objectives

Narrative objectives1

To compare the biodegradable polymer everolimus-eluting stent (Synergy) compared with the durable polymer everolimus-eluting stent (Xience Alpine) in acute ST-segment elevation myocardial infarction (STEMI) in terms of acute thrombogenecity immediately after stent implantation and formation of neoatherosclerosis at 3 years

Developmental phase



Assessment

Primary outcomes

The frequency of neoatherosclerosis lesion which is defined as the presence of a fibroatheroma or fibrocalcific plaques or macrophages within the neointima of a stented segment with a longitudinal extension of >= 1 mm at 3 years

Key secondary outcomes

The athero-thrombotic material area (tissue protorusion + isolated intraluminal detect) within the stent strut after primary PCI
