LDL cholesterol 0.24 is not serious, the value is normal. LDL cholesterol is also known as low-density lipoprotein (LDL) cholesterol, and excess LDL is one of the risk factors for developing atherosclerosis. Measuring LDL cholesterol can provide early recognition of atherosclerosis risk or can be used as a feedback value for patients with coronary artery disease who are taking lipid-lowering medications. The normal range of LDL is less than 3.4 mmol/L. LDL0.24 is within the normal range, so this indicator is normal and the risk of coronary heart disease is small. It is worth noting that patients with a family history of coronary heart disease or abnormal LDL cholesterol should go to a regular hospital in a timely manner, under the guidance of a cardiovascular doctor to standardize the treatment, do not take medication without authorization.
