The post-operative lifespan of coronary artery bypass grafting has been shown by numerous statistics to recur in only 3-4% of patients per year. The survival rate 1 year after coronary artery bypass grafting is generally 95%-98%, 5 years is 90%, 10 years is 80%, 15 years is about 60%-66%, and 20 years can be about 40%, with approximately 40% of patients experiencing angina recurrence after 10 years. However, most patients are not as severe as before surgery and can be controlled by medication, allowing coronary artery transplantation to be controlled. 40% of patients may develop obstruction 10 years after coronary artery transplantation and must undergo another coronary artery bypass graft, but usually the success rate through this graft is lower than the first, so now the technology is getting better and more and more patients are bypassed again. However, the long-term survival rate is not only related to the patient’s age and condition, but also to post-operative visits to the doctor, review, diet, activity, etc., and the ability to adhere to the medication. If a person does not come for review and does not take medication on time, pay attention to personal behavior, life, and moderate exercise, but instead eat a large amount of fish and meat or uncontrolled diet, smoke and drink, it will soon cause great damage to the vascular bridge, so a person’s survival rate is greatly related to his or her life behavior and self-protection awareness after surgery.
