The etiology of coronary heart disease is currently considered to be a combination of factors that contribute to its formation and development over a long period of time. Therefore, it is also said that the factors of coronary heart disease are comprehensive. The main risk factors are the formation of high blood lipids, followed by hypertension, diabetes, aspiration, genetics, age, alcohol, oral contraceptives, emotional stress, low activity, type A personality and abnormalities of certain trace elements. Various factors in the formation of coronary heart disease, internal and external intermingling cause damage to the epidermal cells of the endothelium, and lipids in the blood invade from the damaged endothelium and are deposited underneath the endothelium, initially seeing the formation of lipid streaks, i.e. yellow streaks of varying lengths that do not bulge or bulge slightly underneath the endothelium. With the deposition of large amounts of lipids, the lipid streak increases and forms a scar that protrudes into the lumen, leading to narrowing or even occlusion of the arterial lumen and damage to the vascular endothelium. At the same time, platelets clump here and are activated to release growth factors to promote their cell growth. The injured endothelial cells also release endothelin, which stimulates cell growth and division, resulting in proliferation of endothelial cells and smooth muscle cells in the middle layer of the artery. Macrophages also accumulate at the site of injury. As smooth muscle cells and macrophages engulf a large number of lipids and turn into foam cells, atherosclerotic plaques are formed. Since the site of atherosclerosis formation is not certain, where the deposition is formed leads to local blood circulation supply disorders and a series of symptoms. Coronary heart disease mainly occurs when atherosclerotic plaques are formed in the coronary arteries, when the narrowing of the blood vessel lumen is greater than 50-70%, resulting in the obstruction of blood circulation to the heart, resulting in impaired blood supply.
