[Surface Modification and Applications of Cardiovascular Stent]

Area of Science:

• Biomaterials Science
• Cardiovascular Medicine
• Regenerative Medicine

Background:

• Cardiovascular disease remains a leading cause of mortality globally.
• Coronary artery stent implantation is a primary treatment for coronary artery disease, but restenosis and thrombus formation are significant complications.
• Endothelial impairment following stent implantation is a key factor contributing to restenosis.

Purpose of the Study:

• To review advancements in surface modification of cardiovascular stents.
• To explore strategies for accelerating endothelial regeneration at the stent implantation site.
• To discuss methods and future prospects for promoting in vivo re-endothelialization using biological molecules to prevent cardiovascular restenosis.

Main Methods:

• Literature review of studies focusing on cardiovascular stent surface modification.
• Analysis of research on endothelial regeneration mechanisms post-stenting.
• Examination of various biological molecules and their potential in promoting re-endothelialization.

Main Results:

• Endothelial regeneration is crucial for preventing post-stent restenosis and thrombus.
• Surface modification of cardiovascular stents holds promise for improving outcomes.
• Biological molecules offer potential therapeutic targets for enhancing in vivo re-endothelialization.

Conclusions:

• Accelerating endothelial regeneration at the site of cardiovascular stent implantation is a viable strategy to prevent restenosis and thrombus.
• Surface modification techniques incorporating biological molecules are key to achieving this goal.
• Further research into developing effective methods for in vivo re-endothelialization is warranted for improved interventional cardiology practices.
