High cholesterol is specific to which type of high cholesterol is present, as there is HDL cholesterol, LDL cholesterol, and very low density lipoprotein cholesterol, and elevated cholesterol by itself does not cause a reaction. It is mainly the LDL cholesterol, and the very low density lipoprotein cholesterol, which, if significantly elevated, can lead to risks of coronary heart disease, cardiovascular accidents, and coronary atherosclerosis. Therefore, significantly elevated cholesterol requires timely testing in these areas to prevent sudden cardiovascular and cerebrovascular accidents. Significantly elevated cholesterol also requires the timely use of cholesterol-lowering drugs, especially in the case of combined risks of coronary heart disease, angina pectoris, and cerebrovascular atherosclerosis, it is more important to lower cholesterol at an early stage. However, it should also be noted that it is often better if HDL cholesterol is elevated, because it is a good cholesterol, used to reduce the concentration of LDL cholesterol and very low density lipoprotein cholesterol, which is inversely proportional to the risk of coronary heart disease, angina pectoris, and cerebral atherosclerosis, so the specifics of which type of cholesterol is elevated must also be clarified.
