The length of life after stenting for heart attack needs to be judged according to the specific situation of the patient, and cannot be generalized. Stent implantation after heart attack is a very important measure in the treatment of heart attack, which can save the ischemic damaged and necrotic myocardial cells in time. However, whether myocardial cells can be fully recovered is related to the time of ischemia of the patient. The longer the ischemia time, the lower the possibility of myocardial cell recovery, the possibility of postoperative complications exists, and the life expectancy of the patient may be affected. In addition, if the patient’s bad habits or other underlying diseases are not removed or controlled after surgery, this can also affect the patient’s life expectancy. However, if patients have few underlying diseases and are treated promptly, improve their lifestyle habits after surgery, and take medications as prescribed, life expectancy can usually be 20-30 years or essentially equivalent to normal. If a patient has persistent pain in the anterior chest area and cannot be relieved by nitroglycerin, it is recommended to go to a hospital chest pain center in time, pay attention to good living habits, take medication on time as prescribed by the doctor, and refrain from smoking and alcohol.
