Lipoprotein a high 518 serious. Lipoprotein a is synthesized by the liver, the normal value should be less than 300mg / L. If lipoprotein a is greater than 300mg / L, it may aggravate the coronary atherosclerotic heart disease, and in severe cases, it will increase the occurrence of myocardial infarction, and the patient’s life will be in danger. It is recommended that patients go to the hospital in time to avoid delaying the condition and causing unnecessary damage to the body. There is a direct relationship between lipoprotein A and the occurrence of atherosclerosis in the body. When the level of lipoprotein A is greater than normal, i.e., greater than 300 mg/L, the cardiovascular and cerebral vascular risk due to atherosclerosis will be significantly elevated. The higher the level of lipoprotein a, the greater the risk of cardiovascular and cerebrovascular diseases in patients. Clinically, the risk of cardiovascular and cerebrovascular diseases can be assessed through the test of lipoprotein a. Lipoprotein a levels are affected by many factors, and some medications can also cause elevated lipoprotein levels. Patients with elevated lipoprotein a should pay attention to lifestyle modification, actively control the patient’s blood lipid level, control various risk factors that may lead to cardiovascular and cerebrovascular diseases, and strive to reduce the level of lipoprotein a through comprehensive lifestyle modification. Lipoprotein a abnormally elevated, it is recommended to go to the hospital in a timely manner, identify the causes of symptomatic treatment, do not blindly self-medication.
