A. Understanding coronary heart disease and the danger of coronary heart disease Coronary heart disease is a heart disease caused by atherosclerosis or spasm of the coronary arteries, the blood vessels that supply nutrients to the heart, narrowing or blocking the lumen of the coronary arteries, resulting in myocardial ischemia or necrosis. Coronary heart disease can occur with angina pectoris, myocardial infarction, arrhythmia, heart enlargement and heart failure. The most serious arrhythmia is ventricular fibrillation, which is clinically manifested as sudden death, or Sudden Death, which is the main form of death from coronary heart disease. With the development of economic level, the improvement of people’s living standard, the change of diet structure, the rapid aging of the population, the reduction of exercise, and the increase of mental stress, the high incidence of coronary heart disease and mortality rate is increasing year by year, seriously endangering the health of human beings, and thus is called “the first killer of human beings”. Second, identify the risk factors of coronary heart disease The source of coronary heart disease is not completely clear, but the risk factors of coronary heart disease is very clear. The development of coronary heart disease is closely related to these risk factors. Risk factors for coronary heart disease include preventable and controllable risk factors: dyslipidemia, smoking, diabetes, hypertension, abdominal obesity, lack of exercise, lack of vegetables and fruits in the diet, stress, and alcohol consumption. Risk factors that cannot be prevented and controlled: age, gender, family history of cardiovascular disease. Third, the prevention of coronary heart disease for the risk factors of coronary heart disease Although there are many good drugs and advanced treatment methods for coronary heart disease in recent years, but still can not be the root cause of the disease. Professor Hu Dayi, a famous cardiologist, recently pointed out that the best stents and the most advanced non-stop coronary artery bypass surgery cannot replace the role of prevention. Coronary heart disease control is all about prevention. A large body of evidence shows that diet and lifestyle have an important impact on the development of coronary heart disease and its risk factors, and studies have shown that most cardiovascular diseases are not genetically related, but are caused by poor lifestyle habits. Improving lifestyle can control these risk factors and reduce the risk of coronary heart disease. Although clinical medicine has made great strides in recent years, maintaining a healthy diet and lifestyle is the most effective of all methods for reducing the risk of coronary heart disease in the public. Life expectancy in the United States has increased by 6 years in the last 30 years, with 3.9 years attributable to effective prevention of cardiovascular disease. In view of the risk factors of coronary heart disease, the prevention of coronary heart disease can be achieved through the following measures: 1. The simple calculation of normal weight is: height (cm) – 105 = weight (kg); (2) Those who are over normal weight should reduce the total calories of daily diet, consume low-fat and low-cholesterol diet, and limit sugary foods; (3) Those who are over 40 years old, even if their blood lipids are normal, should avoid frequent consumption of excessive animal fats and foods containing high cholesterol, such as fatty meat, liver, brain, kidney, lung, etc. viscera, squid, bone marrow, egg yolk, crab yolk, etc. If cholesterol and triglycerides are increased, you should eat low cholesterol and low animal fat foods, such as fish, chicken, various lean meats, egg whites, soy products, etc.; (4) Promote a light diet and eat more foods rich in vitamin C and vegetable protein. 2, appropriate physical labor and physical exercise: certain physical labor and physical activity is beneficial to the prevention of obesity, exercise the function of the circulatory system and adjust the lipid metabolism, and is a positive measure to prevent this disease. The amount of physical activity according to the original physical condition, the original physical activity habits and the functional state of the heart to specify, in order not to increase the burden on the heart and not to cause discomfort as the principle. Physical activity should be gradual, should not be forced to make strenuous activities, the elderly advocate walking, health exercises, taijiquan, etc.; 3, control smoking: smoking plays a role in the development of coronary heart disease. It has been reported that in the 35-54 years of age died of coronary heart disease, smokers than nonsmokers 4-5 times more than the risk of more smokers, up to 4-5 times, quit smoking after the incidence of myocardial infarction and coronary heart disease mortality significantly reduced, and the longer you quit smoking the greater the effect; 4, moderate alcohol consumption: a small amount of alcohol is not harmful to coronary heart disease, and even beneficial. People drink a small amount of alcohol in daily life is not inappropriate, the key is to prevent a large amount of alcohol and long-term excessive drinking. If you are suffering from cardiovascular disease, such as hypertension, diabetes, including coronary heart disease, it is best not to drink alcohol, especially white wine should be prohibited; 5, reasonable arrangements for work and life: bad psychological state and the onset of coronary heart disease has a close relationship. Life should be regular, maintain an optimistic and happy mood, avoid overwork and emotional excitement, pay attention to the combination of work and rest, ensure sufficient sleep; 6, treatment of related diseases: early detection and active treatment of high blood pressure, hypertension, diabetes and other diseases related to coronary heart disease, as far as possible to eliminate and control these risk factors, is very important to prevent the occurrence of coronary heart disease.
