80-year-olds can be stented if there are indications for stenting and no contraindications. Although 80-year-old patients are elderly patients, they are not contraindicated for stent implantation. With the advent of population aging, the number of 80-year-olds is increasing, and the number of coronary heart disease has also increased significantly, and patients with indications and no contraindications can be implanted with stents. For 80-year-old patients with symptoms of angina pectoris, routine coronary angiography is recommended to clarify coronary artery lesions, and stents can be implanted in patients with severe stenosis to improve the symptoms of angina pectoris. Elderly patients still need to be treated with dual antiplatelet drugs after stent implantation, usually aspirin combined with clopidogrel, and the risk of bleeding is higher than that of the general population, with a particular focus on preventing gastrointestinal bleeding. Elderly patients are at relatively high risk for stent implantation, and should be treated under the guidance of their physicians, not blindly using their own medications, and taking care to prevent postoperative complications.
