There are three types of treatment for coronary artery disease: medication, intervention and surgical bypass surgery. Drugs can only control the symptoms and stabilize the plaque in the coronary arteries, and they are the foundation. Intervention has been developed in the last 20 years and has matured since 2000, not only for symptom control, but also for the possibility of a complete cure, propping up narrow vessels. Intervention is simple, noninvasive, does not require an open chest, and has immediate results. However, technically it is high-risk and requires certain training and conditions to do, and also requires the cooperation of the patient. In general, nowadays, people are pursuing quality of life in addition to life. A 40-year-old male goes out every day to run, to play golf, and to climb mountains. Although the daily medication does not die, but feel that there is no point in living, we must do intervention, can not do intervention or poor economic conditions (intervention to do seven or eight stents to solve) Then simply give up, consider bypass. In fact, intervention and bypass surgery is a thing, intervention is to open up the blockage inside to unblock; bypass is to open the chest from the upstream to get a tube to the downstream, re-opening a channel. Theoretically speaking, drugs, interventions and surgeries have the same effect on low-risk stable patients, and it is a recognized research result that no one will die from interventions, bypasses or drugs. In general, surgery and intervention have different indications for surgery, and the patient’s financial adaptability and physical condition are generally considered. Interventional patients can climb a mountain, but those who take medication should never climb a mountain. Bypass patients can also climb, but bypass patients have fewer recurrences, interventional patients have more recurrences, and bypass patients have a smaller chance of restenosis. Therefore, patients have to choose the appropriate treatment according to their actual situation, condition and economic situation.
