Coronary heart disease is atherosclerosis in the heart performance, the cause of coronary heart disease, in fact, is the cause of the occurrence of atherosclerosis, if they have the cause of atherosclerosis should always be alert to have coronary heart disease. The causes of atherosclerosis include high blood lipids, high blood sugar, high blood pressure, smoking, lack of exercise, mental stress, increased inflammatory mediators in the blood, elevated homocysteine, depressed personality, or anxious personality, age 50 years or older, male, family history of genetics, if a patient has these risk factors, it is very likely to have coronary heart disease, these patients to the clinical manifestations of coronary heart disease, in fact, coronary heart disease can be The clinical manifestations of coronary heart disease can be divided into five types of manifestations, that is, angina pectoris, myocardial infarction, cardiomyopathy, asymptomatic myocardial ischemia, sudden death. If the pain is not relieved for more than half an hour, we should pay attention to the possibility of myocardial infarction, and some patients are found to have myocardial ischemia when doing exercise test or dynamic ECG, but the patient has no symptoms. These patients are prone to sudden death and must be treated seriously. Some patients present with arrhythmia and heart failure, that is, panic attacks and shortness of breath occur frequently during exertion, and the presence of coronary artery disease should be noted. Of course, people with high suspicion of coronary artery disease should undergo coronary angiography to make a clear diagnosis. If the coronary artery stenosis is more than 75% and is the main vascular lesion, we should pay attention to the treatment of blood transport reconstruction if the standardized medication is not effective, including stent placement, bypass therapy, and even Chinese herbal medicine, but in any case, we should remove all risk factors, such as treating high blood lipids, high blood pressure, high blood sugar, quitting smoking and alcohol, exercising properly, relieving psychological stress, eating more vegetables, eating less animal fat and cholesterol-rich food, such as animal offal, etc. Psychological regulation plays an important role in the prevention and treatment of coronary heart disease. Clinically, it is found that some patients with coronary heart disease are narrow-minded, calculating, or anxious, which are all risk factors for coronary heart disease. Generally, coronary heart disease can be treated by medication and lifestyle changes can slow down the development of the disease, or even reverse the lesion, no need to overstress. Stenting and bypass surgery are both routine and safe procedures. Stenting is suitable for single-branch lesions, while bypass treatment is suitable for multi-branch lesions, or trunk vascular lesions, so you must choose a scientific treatment plan. There are about 300 million chronic cardiovascular patients in China, prevention must be the main focus, medical and nursing staff and the general public should have the scientific knowledge of coronary heart disease, students and teachers should be health science propagandists, so that the cardiovascular disease in China can be well controlled
