The length of life after stenting for coronary artery disease needs to be analyzed specifically according to the patient’s specific condition and cannot be generalized. The patient’s own disease status, age, and lifestyle habits will affect the life expectancy after coronary heart disease stenting. If the patient’s own disease condition is heavy, such as the presence of severe myocardial infarction, is also older, combined with a variety of underlying diseases, and the time to be rescued is also late, the postoperative results are usually poor, and the risk of death is also higher, and the patient’s life expectancy is shorter, possibly surviving 3-5 years. If patients are young, in good health, take medication on time and improve their bad habits after surgery, their life expectancy after surgery can reach 20-30 years, or their survival period may be basically the same as normal people. Patients are advised to review regularly, take medication on time, avoid staying up late and straining, abstain from smoking and alcohol, actively control blood sugar and blood pressure, and eat lightly.
