Bioabsorbable stents offer a promising alternative to traditional stents by degrading safely after providing vessel support. Future nano-theranostic stents could combine therapy and diagnostics for improved cardiovascular care.

Area of Science:

Interventional Cardiology
Biomaterials Science
Nanotechnology

Background:

Percutaneous coronary intervention (PCI) has evolved significantly since 1977.
Drug-eluting stents (DES) improved upon bare metal stents (BMS) but carry higher risks of late stent thrombosis (ST).

Purpose of the Study:

To explore bioabsorbable stents as a solution to ST.
To investigate the potential of nano-theranostic stents for combined therapy and diagnostics.

Main Methods:

Review of current stent technologies and their limitations.
Discussion of bioabsorbable stent mechanisms and advantages.
Exploration of nano-theranostic concepts for future stent development.

Main Results:

Keywords:

bioabsorbable stent drug-eluting stent nanotechnology theranostics
