Atherosclerosis is a disabling and fatal systemic disease that leads to serious consequences including stroke, myocardial infarction, ischemic kidney disease and intermittent claudication. It is a global disease and is the number one threat to human health and life not only in developed countries today, but also an important challenge for developing countries, including China. The occurrence and development of atherosclerosis is a series of processes. In other words, he is not a sudden onset of the disease in a person, but a disease that appears subsequently during the growth of the person itself. This process begins when a person takes his or her first bite of food after birth. During the development of the disease, which is upstream, there is an epidemic of multiple risk factors, including smoking, dyslipidemia, diabetes, obesity, metabolic syndrome, etc. In response to the development of atherosclerosis, we need to form the corresponding line of defense 1, prevention of disease onset, medical science, primary prevention, comprehensive control of the above risk factors to prevent or reduce the occurrence of disease. 2, prevent the event, the so-called event is a stroke, acute myocardial infarction and other major adverse cardiovascular events that cause disability and death. 3, prevent the consequences, once the event occurs, should be actively dealt with, as far as possible to save the heart muscle, save the brain nerve cells, save life. 4, relapse prevention, medicine speaks of secondary prevention, to control the further development of the disease, as far as possible to improve the quality of life of patients. 5, standardized prevention and treatment of chronic heart failure, prevention and treatment of post-stroke sequelae.
