The maximum life expectancy after cardiac stenting is related to the individual’s basic condition and cannot be generalized. In the event of acute myocardial infarction or other causes of occlusion or narrowing of the blood vessels in the heart, a cardiac stent can be implanted in the narrowed area of the blood vessels to open up the occluded blood vessels and restore the normal blood supply to the heart. As its technology matures, it can greatly improve prognosis and quality of life. If the underlying disease is mild, the patient is in good health, and the patient is young, then a longer survival time can be achieved after the implantation of a cardiac stent. On the contrary, if the underlying disease is numerous and untreated, the heart condition is very severe and serious complications occur before stenting, the life expectancy will be significantly affected. However, it is important to note that after implantation of stents, you need to take medication regularly for a long period of time as prescribed by the doctor, and also go to the hospital for regular checkups, closely monitor blood pressure, blood sugar, blood lipids, etc., and eat a light diet with less salt and low fat, so as to improve the quality of life and prolong the length of life.
