Stents are small, expandable tubes that are inserted into a narrowed or blocked blood vessel to keep it open. The lifespan of a stent depends on several factors, including the type of stent, the location of the stent, and the individual's health.
Drug-eluting stents (DES), which release medication to prevent the artery from narrowing again, typically last 10-15 years or longer.
Bare-metal stents (BMS), which do not release medication, generally last 5-10 years.
However, it is important to note that these are just general guidelines. Some stents may last longer or shorter depending on individual circumstances. Regular follow-up appointments with a doctor are essential to monitor the stent's performance and ensure that it remains effective.
Factors Affecting Stent Lifespan:
- Type of stent: DES generally last longer than BMS due to the medication they release.
- Location of the stent: Stents placed in arteries that are prone to narrowing, such as the coronary arteries, may have a shorter lifespan.
- Patient's health: Factors such as smoking, diabetes, and high cholesterol can affect stent lifespan.
Importance of Follow-Up Care:
After receiving a stent, regular follow-up appointments with a doctor are crucial. These appointments allow the doctor to:
- Monitor the stent's performance: Ensure that the stent remains open and effective.
- Check for any complications: Identify any potential problems early on.
- Adjust medications: Ensure that the patient is taking the appropriate medications to manage their condition.
By following a healthy lifestyle and attending regular follow-up appointments, individuals can maximize the lifespan of their stent and maintain good cardiovascular health.
