Patients with coronary artery disease have a gradual recovery process after receiving surgical treatment, both in terms of heart function and systemic status, and the postoperative recovery should be individualized with medical advice because of the differences in the degree of coronary artery disease, heart function status, and physical condition of the patient before surgery. After discharge from the hospital after surgery, without the guidance and care of professional medical personnel at home, disease recovery seems difficult, and the slightest carelessness may lead to disease recurrence or even deterioration. Therefore, patients with coronary heart disease should pay attention to care before surgery, and even more after surgery, mainly the following four points. 1, regular inspection is very important Many patients think that after the stent surgery can rest easy, the blood vessels can always remain open, in fact, not, because of irregular habits, diet, in a period of time after discharge from the hospital relapse is not known. Therefore, 1 month, 3 months, 6 months, 9 months, 1 year after surgery is the key time point for follow-up, it is best to go to the hospital for detailed examination. 2. Insist on taking medication after surgery The stent only solves the problem of a section of blood vessel, and does not “remove the root”. . 3, diet and exercise is the key In addition to regular follow-up and daily adherence to medication, a healthy diet and appropriate amount of exercise is also the key to keep coronary heart disease from recurring. First, absolutely quit smoking, smoking will accelerate platelet agglutination, causing myocardial ischemia, resulting in stent implantation site endothelial restenosis. Second, avoid eating more high fat, high cholesterol, high salt, high sugar food. Third, avoid eating too much and overeating. It is best to control each meal at sixty to seventy percent full; when conditions permit, it is best to have a small number of meals, but each meal is half full. Fourth, moderate exercise, such as daily walks. Generally each time in the range of 20 to 30 minutes, after adhering to a week or two without abnormal reaction, can be increased to 45 minutes to 1 hour, 3 to 5 times a week is appropriate. 4, “heart” good everything is good Do not think that occasionally angry, sad face, depressed about it does not matter. The negative psychological emotions such as depression, anxiety and resentment can cause damage to the heart. After coronary heart disease patients receive stent treatment, if the reasons for bad heart persist, they will easily relapse, the relapse rate can be as high as 8.7% to 29.6%, and the most relapses within two years, and may even relapse again or multiple times. Therefore, patients with coronary heart disease should not take it lightly after stent placement, and should take strict preventive measures.
