Stent implantation in 75-year-olds can help improve their condition and quality of life; however, the procedure may cause complications and the pros and cons need to be weighed with a doctor’s advice. 1. Benefits: Stenting, or intracoronary stenting, can be used for acute heart attacks, . severe narrowing of the coronary arteries, and coronary artery disease that makes it difficult to tolerate surgical bypass surgery. The procedure can help improve coronary artery stenosis, thus restoring blood supply to the heart muscle and alleviating chest pain and chest tightness due to hypoxia and ischemia. 2. Disadvantages: However, the surgery may be associated with the risk of blood clots, perforation, and may even lead to malignant arrhythmias and risk of sudden death. The procedure should not be performed if there is a history of bleeding disorders, or severe liver or kidney dysfunction. If you are eligible for stent implantation, you should follow your doctor’s instructions to take the correct medication after the procedure and closely monitor your physical condition, and consult your doctor if there is any abnormality.
