Low-salt, low-sugar, low-fat, low-cholesterol, light and digestible, high-quality protein diet. Let me introduce some health care knowledge to you. A. Proper exercise After coronary intervention, patients should not stay in bed and sit still all day, but should exercise properly under the guidance of a doctor. Regular exercise is helpful to keep the coronary artery lumen unobstructed and promote the growth of myocardial collateral vessels in ischemic area. Generally speaking, the level of postoperative activities should be based on preoperative physical condition, activity habits, postoperative heart condition and environment, and aerobic exercise, such as walking, doing exercises and playing Tai Ji Chuan, should be advocated. Note: Exercise must be moderate. Please consult your doctor before doing any exercise. B. Changing diet structure and eating habits A good diet is helpful to control blood lipid and blood pressure, thus preventing coronary restenosis. After percutaneous coronary intervention, we should talk about diet. protein should focus on fish and avoid overeating or overeating. Eat more fresh vegetables, fruits, lean meat, chickens, ducks, rabbits, fish, bean products and dairy products. It is not advisable to eat animal viscera, squid, crab roe, egg yolk, fried, fried, grilled and other foods frequently or in large quantities. C. maintain emotional stability and avoid great joy and great sorrow. Literature shows that patients with coronary heart disease have different degrees of psychological stress once diagnosed, which will accelerate the progress of arteriosclerosis and increase the occurrence of cardiac emergencies. 2) Main risk factors for treating coronary heart disease A. Actively treat diabetes. For patients with coronary heart disease complicated with diabetes, fasting blood glucose or postprandial blood glucose should be controlled at a normal level. B. control blood pressure. Patients with hypertension should take drugs under the guidance of a doctor and control their blood pressure below 140/90mmHg. C, lowering blood lipid, lowering blood total cholesterol level to below 65,438+0.80mg/dl, low density lipoprotein to below 65,438+0.00mg/dl, and triglyceride to below 65,438+0.70/dl. 3) Weight control is not only conducive to lowering blood lipids and controlling hypertension, but also can reduce the burden on the heart, thus preventing the recurrence of coronary heart disease. 4) Quit smoking 5) Taking aspirin, an antioxidant or anti-atherosclerosis drug, can inhibit platelet aggregation, have anti-inflammatory and anti-oxidation effects, and help prevent and treat atherosclerosis. Statins can not only reduce blood cholesterol, but also increase high density lipoprotein, which has the functions of stabilizing coronary atherosclerotic plaque, anti-inflammation and protecting vascular endothelium, and can reduce the occurrence of cardiac emergencies. Coronary stent is to expand the narrow part of coronary artery by interventional method and put it into metal stent to support the narrow part, so that the narrow blood vessel wall expands outward. After stent implantation, new endothelial cells gradually cover the surface of the stent, so that the stent is finally completely embedded in the blood vessel wall, supporting the blood vessel to remain open continuously and keeping the coronary artery unblocked.
