① Lowering cholesterol (cholesterol 1): As we all know, hypercholesterolemia is the most important risk factor for coronary heart disease. To reduce cholesterol, we must first manage our mouth, eat less cholesterol-rich foods such as animal viscera, egg yolk and fat meat, and try to reduce excessive cholesterol; If serum cholesterol can't drop to normal level after diet control, you must take lipid-lowering drugs. The most commonly used drugs are statins, such as simvastatin, pravastatin and atorvastatin. Try to reduce serum cholesterol below 4.6 mmol/L( 1.80mg/dl). These drugs can not only lower cholesterol, but also stabilize atherosclerotic plaques and reduce the incidence of acute coronary events. ② Cigarettes: Quitting smoking can not only reduce the incidence of chronic bronchitis, emphysema, pulmonary heart disease and lung cancer, but also reduce the damage of smoke to vascular endothelium, thus achieving the purpose of preventing and treating coronary heart disease. Smoking has many harms but no benefits, so smokers are advised to take care of themselves. D, including two D's: ① Prevention and treatment of diabetes: Diabetes not only increases blood sugar, but also is often accompanied by lipid metabolism disorder, which is another risk factor of coronary heart disease. By controlling diet, applying hypoglycemic drugs and lipid-lowering drugs, controlling blood sugar at about 6 mmol/L and serum cholesterol below 4.6 mmol/L, the recurrence rate of coronary heart disease can be greatly reduced. 2 Diet control: In a sense, coronary heart disease is eaten! Therefore, in addition to eating less foods rich in cholesterol, patients with coronary heart disease advocate eating eight points full and avoiding overeating, which is the best fitness method. I suggest you go to a regular big hospital first. If there is no myocardial infarction, it can be definitely diagnosed as coronary heart disease. If you don't have any contraindications to exercise treadmill test, do exercise treadmill test to definitely diagnose coronary heart disease. Then the treatment will be carried out to avoid wasting money. However, some of the above health care methods are still worth observing, which is conducive to the prevention of coronary heart disease.
