[If stent is indicated, which one should be chosen?]

Area of Science:

• Interventional Cardiology
• Cardiovascular Medicine
• Biomedical Engineering

Background:

• Coronary stenting is a key intervention in managing coronary artery disease.
• Established indications include preventing acute complications and treating specific lesion types.
• The prevention of restenosis remains an area for further research and optimization.

Purpose of the Study:

• To review the current indications and limitations of coronary stenting.
• To discuss factors influencing stent selection and future directions in preventing restenosis.
• To highlight the role of functional assessment in patient selection for stenting.

Main Methods:

• Review of current clinical practices and literature on coronary stenting.
• Analysis of indications for stenting, including acute complications and specific lesion types.
• Discussion of emerging techniques for restenosis prevention and patient selection.

Main Results:

• Coronary stenting is proven to prevent acute angioplasty accidents and is valuable for chronic occlusions and venous grafts.
• Restenosis prevention is not an absolute indication for primary stenting; functional assessments may guide patient selection.
• The ideal stent characteristics are defined, though no single stent possesses all desired attributes.

Conclusions:

• Coronary stenting is essential for managing acute angioplasty complications and specific coronary lesions.
• Functional assessment techniques could refine patient selection for stenting, particularly for restenosis prevention.
• Future research should focus on advanced techniques to limit or prevent intrastent intimal hyperplasia.
