The incidence of hyperlipidemia is very high, with about 90 million people suffering from hyperlipidemia in China. This disease is insidious, gradual, progressive and systemic, especially harmful to the heart, brain, kidney and blood vessels, and is often the basis for the development of cardiovascular and cerebrovascular diseases, so hyperlipidemia is also known as the “silent killer” and the “source of many diseases”. At the same time, it is cunning because patients with hyperlipidemia may not show obvious symptoms, and it takes time for other types of hyperlipidemia, except familial hyperlipidemia, to develop into coronary heart disease and stroke, so it is easy to ignore the danger of hyperlipidemia. The most important and direct damage of hyperlipidemia is to accelerate systemic atherosclerosis, because all important organs in the body depend on arteries for blood and oxygen supply, and once the arteries are blocked by atheromatous plaque, it will lead to serious consequences. And hyperlipoproteinemia is the main cause of atherosclerosis. When the body has more blood lipids than the body needs due to various factors, cholesterol and other substances are deposited on the walls of blood vessels, gradually causing hardening and narrowing of blood vessels. This is a slow process, and patients can be asymptomatic for a long period of time, but when the fat accumulated on the walls of blood vessels reaches a certain amount, quantitative changes cause qualitative changes, and the corresponding organs supplied by the blood vessels will become diseased due to ischemia. In the heart, it can cause coronary heart disease and acute myocardial infarction; in the cerebral arteries, it can cause cerebral blood supply deficiency, cerebral infarction and cerebral embolism; in the kidneys, it can cause renal arteriosclerosis and even stenosis, renal failure, uremia and intractable hypertension; in the lower limb arteries, it can cause lower limb arteriosclerosis and even stenosis, showing intermittent claudication, or lower limb artery occlusion and necrosis.
