Coronary atherosclerosis, in fact, is short for coronary atherosclerosis. At present, it is clear that there is no atherosclerosis without cholesterol. The degree of atherosclerosis can be divided into mild to moderate to severe, generally mild to moderate we medication, severe with the help of the means of devices, and then supplemented with medication In fact, the formation of atheromatous plaque begins in childhood time, and generally over decades of gradual aggravation process. Therefore, early prevention and early intervention are necessary. Age, male, dyslipidemia, hypertension, smoking, diabetes and abnormal glucose tolerance, obesity, physical inactivity, and family history are the more definite risk factors for coronary atherosclerosis, and others such as type A personality, oral contraceptives, and eating high-calorie foods are also considered as risk factors for early onset of coronary atherosclerosis. Coronary atherosclerosis, which is characterized by the thickening and hardening of the arterial wall, loss of elasticity and small lumen, has a core mechanism of coronary artery endothelial damage and lipid deposition, and atherosclerotic plaque formation. When coronary artery atherosclerosis causes lumen narrowing or occlusion, it can lead to myocardial ischemia and hypoxia. The plaques of coronary atherosclerosis vary and can be divided into stable plaques and unstable plaques. The former has a thick fibrous cap; the latter has a thin fibrous cap, but a large lipid nucleus, which is extremely easy to rupture. Due to the different composition of coronary atherosclerotic plaques and the different degree of stenosis, when coronary atherosclerosis causes luminal narrowing or occlusion, resulting in myocardial ischemia and hypoxia or necrosis and causing heart disease, it is called coronary atherosclerotic heart disease (coronary heart disease). There are also a few people who do not have obvious atheromatous plaque, but the hardening of blood vessels and poor endothelial function cause blood vessels to spasm easily and cause myocardial ischemia (i.e., angina), and in severe cases, the blood vessels can be completely occluded and myocardial infarction occurs. Coronary arteriosclerosis is part of systemic atherosclerosis, and coronary artery disease occurs when there is coronary artery stenosis or occlusion leading to myocardial ischemia/necrosis. Aggressive control of risk factors at an early stage is required.
