How long a 65-year-old heart can live with 2 stents is related to the condition. Patients with stable coronary artery disease have a longer survival date after stenting; patients with severe coronary artery disease will have a shorter survival period, and even have the risk of sudden death. Cardiac stents for elderly patients are mainly used in the treatment of severe coronary artery disease. For patients with relatively mild conditions and simple limited stenosis, patients recover better after stenting, and if they can adhere to the treatment, most of the patients have a longer survival date. A small number of patients implanted with stents may have acute myocardial infarction. The larger the infarction, the more severe the condition, and although stents are implanted for treatment, patients are likely to develop severe heart failure, and their survival time will be shortened, and there is even a risk of sudden death. Patients after stenting should have regular checkups and regular treatment under the guidance of a physician. When uncomfortable symptoms occur, please seek medical attention promptly.
