Can a stent last more than 30 years?

After receiving a stent, the heart can typically function for more than 30 years.

A cardiac stent is a medical device, and implanting a stent into the coronary artery is an effective treatment method. Coronary artery narrowing or blockage is a manifestation of coronary heart disease. If the coronary arteries become narrowed or blocked, it may lead to ischemia, hypoxia, functional disturbances, or even tissue necrosis. During interventional surgery, doctors implant a stent into the coronary artery to expand the blood vessel and maintain its patency, thereby restoring adequate blood supply. If patients have good cardiac function, receive timely and effective treatment, and strictly follow medical advice regarding medication, their life expectancy can be significantly prolonged. Some patients with coronary heart disease can live up to 30 years or more after stent placement—potentially reaching a lifespan comparable to those without coronary heart disease.

In terms of materials and structure, cardiac stents are designed for lifelong use; they do not rust or break. However, as a foreign body in the human system, the stent may trigger biological responses that could lead to restenosis of the vessel or even thrombosis. Therefore, any symptoms of discomfort should prompt immediate medical attention.

After stent placement, it is important to take medications regularly as directed by a physician, improve unhealthy lifestyle habits, and undergo regular follow-up examinations to promote recovery and long-term health.
