The survival time after cardiac stenting depends on the cause of the patient’s disease as well as the maintenance, and there is no uniform standard. Cardiac stents are mainly used for coronary artery stenosis, the main causes of which are coronary heart disease and angina pectoris. If the patient can take medication on time after receiving cardiac stent surgery; actively manage biochemical indicators such as blood pressure, blood lipids, and blood glucose under the guidance of the clinician; and return to the hospital for review in a timely manner, the patient’s survival can be significantly prolonged, and there is no significant impact on survival. If the stent is implanted for the treatment of acute myocardial infarction and the infarcted area of the heart is large, this type of surgery is more difficult. And sudden death is likely to occur during the procedure, and even if a cardiac stent is implanted, the prognosis for survival is not long. If the patient does not strictly follow the medical advice, the survival time may be around 1~2 years. The appearance of cardiovascular system diseases need to seek medical treatment as soon as possible to avoid delays.
