Lipoprotein(a), often abbreviated as Lp(a), is a type of lipoprotein found in your blood. It's important because high levels of Lp(a) can increase your risk of cardiovascular diseases, such as heart attacks and strokes. Understanding your Lp(a) levels can help you and your healthcare provider manage your heart health more effectively.
What is Lipoprotein(a)?
Lipoprotein(a) is a particle that carries cholesterol in your blood, similar to low-density lipoprotein (LDL), which is often referred to as "bad cholesterol." However, Lp(a) has an additional protein called apolipoprotein(a), which makes it unique. This protein can contribute to the build-up of fatty deposits in your arteries, increasing your risk of cardiovascular disease.

Normal Lp(a) Reference Range
For adults, the typical reference range for Lp(a) levels is from 0 to 75 nmol/L. Levels below 75 nmol/L are associated with a lower risk of cardiovascular diseases. On the other hand, levels equal to or greater than 125 nmol/L are considered to indicate a high cardiovascular risk, as per the European Society of Cardiology (ESC) guidelines from 2019.
Why Lp(a) Levels Matter
High levels of Lp(a) in your blood can lead to the development of atherosclerosis, a condition in which fatty deposits build up in your arteries. This can narrow and harden your arteries, restricting blood flow and potentially leading to heart attacks or strokes. Monitoring Lp(a) levels can be particularly important if you have a family history of cardiovascular diseases.
Factors Affecting Lp(a) Levels
Lp(a) levels are primarily determined by genetics, meaning they can be inherited from your parents. Unlike other cholesterol levels, Lp(a) is not significantly affected by lifestyle changes such as diet or exercise. However, certain medical treatments and interventions may help manage high Lp(a) levels.
Frequently asked questions
What is considered a normal Lp(a) level?
A normal Lp(a) level is typically between 0 and 75 nmol/L. Levels below 75 nmol/L are associated with a lower risk of cardiovascular issues.
What does a high Lp(a) level mean?
An Lp(a) level of 125 nmol/L or higher is considered high and indicates an increased risk of cardiovascular diseases, according to the ESC 2019 guidelines.
Can Lp(a) levels be reduced?
While lifestyle changes have little effect on Lp(a) levels, certain medications and treatments may help manage high levels. Consult your healthcare provider for personalized advice.
Are Lp(a) levels hereditary?
Yes, Lp(a) levels are largely determined by genetics and can be passed down from your parents.
When to see a doctor
If your Lp(a) levels are equal to or greater than 125 nmol/L, it is advisable to consult a healthcare professional. They can provide guidance on managing your cardiovascular risk and discuss potential treatment options. Additionally, if you have a family history of heart disease, it may be beneficial to discuss Lp(a) testing with your doctor.
