[The research progress in intravascular stent endothelialization]

Area of Science:

• Cardiovascular Medicine
• Biomedical Engineering
• Regenerative Medicine

Context:

• Percutaneous transluminal coronary stenting is a common procedure for treating coronary artery disease.
• Restenosis, the re-narrowing of the artery after stenting, remains a significant clinical challenge.
• Endothelialization of stents is crucial for long-term patency and preventing restenosis.

Purpose:

• This review discusses factors influencing stent endothelialization.
• It highlights the potential of endothelial cell and endothelial stem cell-based strategies for stent applications.
• The aim is to provide insights into improving stent performance and reducing restenosis.

Summary:

• Restenosis following coronary stenting is a persistent problem for interventional cardiologists.
• Emerging evidence suggests that seeding stents with endothelial cells, particularly endothelial stem cells, may offer novel therapeutic approaches.
• Key factors influencing successful stent endothelialization are examined in this review.

Impact:

• Understanding stent endothelialization can lead to improved stent designs and therapeutic strategies.
• This research may pave the way for reduced restenosis rates and better patient outcomes.
• The findings could advance the field of regenerative medicine in cardiovascular interventions.
