Objectives

Narrative objectives1

The objective of this study is to analyze the radial wall strain (RWS) in the vascular wall within 5 mm proximal and distal to the stent edges (illustrated schematically) as observed on coronary angiography (CAG) after stent implantation. The study focuses on patients with coronary artery disease who underwent percutaneous coronary intervention (PCI) using second-generation or later drug-eluting stents (DES). Furthermore, it aims to investigate the relationship between RWS at the stent edges and late stent-edge restenosis during the long-term follow-up period after stent implantation.

Assessment

Primary outcomes

RWS values at stent edges on post-pci cag in stent edge restenotic and non-restenotic lesions

Key secondary outcomes

1) RWS values at stent edges on post-PCI CAG in clinical stent edge restenotic and non-restenotic lesions
2) RWS values at stent edges on pre-PCI CAG in stent edge restenotic and non-restenotic lesions
3) Target Lesion Revascularization (TLR)
4) Target Vessel Revascularization (TVR)
5) Culprit Lesion-Related Major Adverse Cardiac Events (CL-MACE)
6) Stent Edge-Related Major Adverse Cardiac Events (Stent Edge-Related MACE)
7) In-Stent Segment-Related Major Adverse Cardiac Events (In-Stent Segment-Related MACE)
8) Cardiac Death
