Stenosis of the left anterior descending branch of the coronary artery cannot be normalized by medication alone, but it can be normalized by surgical implantation of a stent. Stenosis of the left anterior descending branch of the coronary artery occurs mostly due to coronary atherosclerosis, which is incurable, and can only be maintained for a long period of time by medication and a light diet. With the increase of age and the prolongation of the disease, the stenosis of the left anterior descending branch may develop further. At this time, it is recommended to pay attention to a light diet in daily life, quit smoking and drinking, and control blood pressure, blood lipids and blood glucose within the normal range. And we should insist on long-term medication and regular review to prevent the left anterior descending stenosis from aggravating and causing coronary artery blockage. When the situation is serious, a stent can be surgically implanted in the stenosis to reopen the coronary arteries as prescribed by the doctor. It is important to note that after implantation of a stent, it is necessary to take medication for life and pay attention to diet to prevent the stent from becoming blocked again. If there is a stenosis of the left anterior descending branch, it is recommended to go to the hospital and follow the doctor’s instructions for treatment.
