There is no clear age requirement for cardiac stenting, and the severity of the condition and physical fitness should be referred to. Cardiac stent implantation is mainly used for the treatment of severe coronary artery stenosis, and can be used for the rescue of patients with acute myocardial infarction. There is no clear clinical requirement for the age of the patient, and stent implantation can be performed at any age as long as the physical quality is permissible, the condition requires it, and the family agrees to the surgery. There is no absolute contraindication to stent implantation, most patients with coronary artery stenosis can be implanted with stents, but for patients with diffuse coronary artery lesions, who cannot be implanted with stents, bypass grafting is required. Clinical stenting of patients should take into account the patient’s physical condition, the severity of the disease, and grasp the indications for stenting, and should be carried out by professional cardiologists.
