After the placement of an arterial stent in a 75 year old patient, with scientific and effective treatment, life expectancy is generally not affected and patients can survive for several years to decades if no serious complications occur. Interventional stenting for the treatment of arterial stenosis is now widely used in clinical practice. The treatment is safe and effective. After the procedure, patients are treated with dual antiplatelet therapy of varying durations to prevent reinfarction or in-stent thrombosis, often for 6 to 12 months. An antiplatelet agent (e.g., aspirin) may then be used for long-term maintenance. The risk of postoperative complications in patients who have undergone rigorous medical therapy is small and generally does not affect the patient’s survival. However, for patients who are not treated according to the doctor’s instructions, premature postoperative activity and lack of scientific care, it may lead to cardiovascular and cerebrovascular accidents, with a higher rate of postoperative complications, and a decrease in the survival rate and survival period. It is recommended to consult the doctor promptly if there is any discomfort after the operation to avoid delaying the condition.
