Recent studies have expanded the prevention of coronary heart disease from the traditional control of risk factors to the advanced stage of reducing risk factors from the early age. The prevention and treatment of coronary heart disease should start from children, from the control of risk factors, to prevent the onset and consequences of events, and advocate the viewpoint of “prevention”. Early childhood to avoid the formation of risk factors domestic and foreign research data show that atherosclerosis begins in early childhood, the earliest seen in newborns. It is suggested that prevention of coronary heart disease should be started from “children”: cultivate good living and eating habits from childhood, balance diet, do not choose food, do not eat partially; reduce the intake of fat, egg yolk, offal and other foods; increase the intake of vegetables, use more soy products and light foods, and appropriately limit the intake of sugar and salt. Actively participate in physical activities. Develop a good work and rest schedule, combine work and rest, do not play exciting games, and prevent mental tension. Parents and schools should strengthen education to avoid becoming “young smokers”. Smoking cessation in adulthood: quit smoking if you are an active smoker, and persuade people around you to quit smoking if you are a smoker. Limit alcohol: Do not abuse alcohol, drink small amounts of alcohol, no more than 50 grams of white wine and no more than 500 ml of beer per day. Control blood pressure: If blood pressure is >140/90 mmHg measured at different times in the morning and evening, it should be retested at different times within 4 weeks. If still >140/90mmHg, should receive treatment to control blood pressure in the normal range <140/90mmHg; if <140/90mmHg, measured at 3 months interval for 1 year. In case of diabetes, blood pressure should be controlled below 130/80mmHg. It should be noted that there are many antihypertensive drugs with different mechanisms of action and characteristics, and appropriate drugs should be selected by a professional physician according to the specific situation. It is not advisable to choose short-acting preparations with rapid onset of action on your own. Monitor blood pressure during medication and consult a physician when adverse reactions are detected, and do not stop medication without authorization. Dyslipidemia: Dyslipidemia refers to an increase in total cholesterol, LDL cholesterol and triglycerides, and a decrease in HDL cholesterol. Adults aged 20 years and older should receive lipid screening at least once every 5 years. Men older than 45 years of age and women older than 55 years of age should have their blood lipids checked every 1 to 2 years. Blood lipids above the normal range should begin with lifestyle changes: eat 8% to 10% of total calories from saturated fat, 30% or less from total fat, and eat cholesterol <300 mg/day. Blood lipids should be rechecked at 4-6 weeks and 3 months after changing the diet, and intensive diet therapy should be adhered to for 6 months. Patients whose lipids do not drop or whose lipid levels are abnormally elevated should receive lipid-regulating treatment from a medical professional. Blood glucose control: Patients with diabetes should actively and strictly control their diet, take glucose-lowering drugs or use insulin to lower blood glucose to normal range. Exercise: Evidence shows that doing vigorous exercise two or three times a week can reduce the risk of getting heart disease. However, because it is dangerous to do strenuous exercise suddenly, it must be started in a gradual manner. Weight loss: Reduce the intake of fat, egg yolk, offal and other foods, increase the consumption of vegetables, use more soy products and light foods, and eat 6 to 80% full at each meal is a viable way to lose weight. Starvation therapy for weight loss should be used sparingly or not. Balanced diet: eat less cholesterol and spicy and stimulating food, and eat more vegetables, beans and soy products that contain more vitamin C. Use vegetable oil for frying and less salt. Cholesterol intake below 300 mg per day for people at high risk of coronary heart disease. Eat more deep-sea fish with scales. Avoid "overwork" and mental tension: you should go to bed early and get up early, avoid staying up late, and you should not read tense and scary novels and TV before going to bed. You can relieve the tension in daily life by developing hobbies or sports.
