Whether you dare to have a cardiac stent in your 80s requires a comprehensive assessment of your health and then a decision. If the basic physical condition is good, it is possible, but not vice versa. If you are in good physical condition and can tolerate the surgery after a comprehensive evaluation, such as lung function and cardiac ultrasound, you can have the surgery. If you have serious lung disease or underlying disease such as heart failure, the surgery may cause more serious physical and mental trauma, and may even be life-threatening. Cardiac stent surgery is done because the main blood vessels supplying blood to the heart are blocked, affecting the blood supply to the heart, putting a stent to open the blood vessels can save some of the heart muscle cells, but the premise must be that the body can tolerate this surgical treatment, and after the surgery must be closely observed vital signs. Whether the surgery can be performed or not needs to be evaluated by a professional doctor in a regular hospital.
