The normal value of lipoprotein a is in the normal range of 0-300mg/L, so 700mg/L is very high. As an independent risk factor for atherosclerosis, lipoprotein a is closely related to the occurrence of atherosclerosis, coronary heart disease, restenosis after myocardial infarction, or stroke, and the incidence of coronary heart disease is 3 times higher in those with greater than 300mg/L than those with less than 300mg/L, and the risk of stroke is increased 4.6 times in those with greater than 497mg/L than those with less than 497mg/L. Elevated lipoprotein A can also be seen in type 1 diabetes, kidney disease, inflammation, hemodialysis, post-surgery and other conditions. Elevated lipoprotein a please go to the hospital, identify the cause and timely treatment, do not blindly use drugs to avoid delaying the condition.
