Stent surgery generally does not affect life expectancy, and normally, without complications, patients can survive for several years to decades, depending on their own physical condition. Stenting is now one of the most common treatments for coronary heart disease, cerebral stenosis and other cardiovascular diseases. The survival rate after stenting varies greatly depending on the operation and postoperative recovery. 1. If the procedure goes well and there are no postoperative complications, life expectancy will not be affected and the patient can survive for decades. 2. If the procedure goes well, but complications such as in-stent restenosis or stent thrombosis occur within one year after the procedure, thrombolysis or other further treatment should be carried out promptly, otherwise sudden death may occur. 3. When stenting is a remedial procedure, the risk of postoperative complications is greatly elevated and the survival rate of the patient is greatly reduced. In addition, after placing the stent, it is necessary to pay attention to scientific work and rest, appropriate strengthening exercise, reasonable diet, must avoid staying up late, frequent strenuous exercise, high salt and high fat diet. In addition, it is also necessary to pay attention to the monitoring of blood pressure, blood glucose, blood fat and other indicators, the elevation of these indicators will largely promote the stent thrombosis, restenosis and other complications, thus affecting the life expectancy.
