The number of years a heart stent can last varies from person to person and can be up to a lifetime. The quality of life of patients after cardiac stenting can be greatly improved if they are able to take the right medications on time, combined with good lifestyle interventions. Patients with severe stenosis in the coronary arteries of the heart have a longer survival and better prognosis with stenting than without. If a patient’s cardiac coronary arteries remain in a state of severe stenosis, it can lead to myocardial infarction and progressive heart failure at any time. Stents can improve blood flow in the coronary arteries and relieve the symptoms of myocardial ischemia. Combining the above factors, controlling one’s blood pressure, blood lipids, blood sugar and other indicators, exercising more, changing dietary habits, and taking medication in strict compliance with the doctor’s prescription and regular review, cardiac stents will improve the quality of patient’s survival very well, and also maximize the life span of the stent.
