LDL-C stands for low-density lipoprotein cholesterol, which is a very important indicator in lipid tests. The higher this indicator is, the more likely the patient is to develop atherosclerotic disease, especially in the cardiovascular department, which pays great attention to this indicator and generally wants to control it within the standard range. If the patient has already had a heart attack, brain attack or has some high risk factors for cardiovascular disease, the index should be lowered to below the standard range to better prevent the progression of atherosclerosis. For patients with high LDL cholesterol, the preferred lipid-lowering drugs are statin lipid-lowering drugs, and the representative drugs are atorvastatin, simvastatin, pravastatin, etc. These drugs not only help to reduce LDL cholesterol, but also improve the endothelial function of blood vessels and prevent the progression of atherosclerosis.
