Atherosclerotic disease is the number one killer of human health and human life today. In Europe, the United States and most economically developed regions of China, death due to atherosclerosis has surpassed cancer as the leading cause of disease. Atherosclerosis is often asymptomatic in its early stages, a state that can last for years or even decades, and then it can suddenly explode with fatal diseases such as localized ischemia, angina, myocardial infarction, heart failure, cerebral infarction or brain hemorrhage. The consequences of atherosclerosis are the most common cause of death. So how does atherosclerosis arise? The main internationally recognized theories include the lipid infiltration theory, the endothelial damage theory and the inflammatory response theory. The formation of atherosclerosis can be briefly described as the following process: due to high blood pressure, smoking, diabetes and other reasons, the endothelium of blood vessels is gradually damaged by invasion, and the lipids in the flowing blood, especially low-density lipoproteins, enter the layer under the endothelium through the gaps of the injured endothelium. which is the most important component of atherosclerosis, and over time, atherosclerosis becomes more and more serious, leading to the outbreak of the most serious and fatal diseases mentioned above. Therefore, nowadays, people are trying to quit smoking, control blood pressure, control blood lipids and treat diabetes in order to delay and reduce the development of atherosclerosis.
