Lipoprotein a as high as 1000mg/L is more serious and requires intervention as soon as possible. The normal reference range for lipoprotein a is 0-300mg/L, so 1000mg/L is a relatively high level. At the same time, due to the structure of lipoprotein a is very similar to LDL, so it also has the ability to carry cholesterol, there is a role in promoting atherosclerosis; at the same time, it is also homologous to the fibrinogen, and its increased level can promote thrombosis, so it is often used as an independent risk factor for atherosclerosis and thrombosis. Therefore, it is recommended to intervene in time, avoid oily and high-salt diet, quit smoking, maintain appropriate physical exercise, and take niacin for adjuvant therapy after consulting with a doctor. If necessary, please consult a doctor for standardized diagnosis and treatment.
