Insights
In-stent restenosis (ISR) is a common complication after stenting for cardiovascular disease (CVD). This review examines the latest monitoring and treatment technologies for ISR, aiming to improve future stent systems.
Area of Science:
- Biomedical Engineering
- Cardiovascular Research
- Medical Device Technology
Background:
- Cardiovascular disease (CVD) involves arterial narrowing due to plaque, often treated with stents.
- Stent deployment can cause inflammation, leading to in-stent restenosis (ISR), a major cause of death.
- Early detection and monitoring of ISR are crucial for effective treatment.
Purpose of the Study:
- To review current technologies for monitoring and treating ISR.
- To identify potential issues and offer suggestions for existing ISR technologies.
- To encourage the development of advanced stent systems with improved electromechanical performance, size, functionality, and reliability.
Main Methods:
- Literature review of recent advancements in ISR monitoring and treatment.
- Analysis of potential challenges and limitations of current technologies.
- Synthesis of findings to propose future research directions.
Main Results:
- Identified key technologies for ISR monitoring and treatment.
- Highlighted challenges including inflammation, tissue overgrowth, and detection difficulties.
- Presented suggestions for enhancing stent systems.
Conclusions:
- Advanced stent systems are needed to address ISR effectively.
- Future research should focus on improving stent electromechanical properties, size, functionality, and reliability.
- Enhanced monitoring and early diagnosis are critical for managing ISR and improving patient outcomes.
Abstract:
Cardiovascular disease (CVD) can progressively narrow arteries due to plaque accumulation on the inner walls of the blood vessels, which results in an obstructed blood flow, leading to heart attack, stroke, and even death if the obstruction is severe. A popular treatment for the disease is to use an intravascular mechanical device called the stent to achieve an immediate restoration of blood flow. However, the physical stimulation induced by the stent expansion can cause inflammation of the vessel tissue. As one of the most common post-stenting complications, re-narrowing of the vessel is the main pathology that leads to in-stent restenosis (ISR), induced by the excess growth of the tissue over the deployed stent. The ISR is widely recognized as a significant cause of death globally if early symptoms are not detected. Hence, monitoring and early diagnosis indeed matter when it comes to treatment. The latest technologies for monitoring and treatments of ISR were reviewed in this work, and the potential issues and suggestions related to the reported technologies were presented. The target of this review aims to positively prompt researchers to develop an advanced stent system in terms of its electromechanical performance, size, functional feature, feasibility, and reliability.
