Age is not a major determinant of whether an 83-year-old is suitable for stenting. If he is in good physical condition and has relatively good blood vessel condition, he can undergo stenting; however, if he is in poor physical condition and has severe stenosis in several blood vessels, he is not suitable for stenting. Those who are in good physical condition, have no underlying disease, and only have moderate to severe stenosis in 1 or 2 non-trunk vessels can improve the condition of coronary arteries by stenting. Patients with bleeding disorders, tumors, severe liver and renal function abnormalities, and severe stenosis in multiple vessels are not suitable for stenting treatment, and bypass surgery can be performed in some groups. The 83-year-old man himself has obvious coronary artery disease, the symptoms continue to aggravate, need to be admitted to the hospital in a timely manner to seek medical treatment, under the guidance of clinicians to regulate the treatment, to avoid causing delays in the condition.
