Understanding Lp(a)
and Your Risk for Heart Disease
Heart disease is the leading cause of death in the United States.1
High Lp(a) is mostly inherited
and can increase your risk for heart disease.2
Knowing your risk factors can help you stay
healthy for yourself, your family, and your job.3
What Is Heart Disease?
What Is Lp(a)?
Lipoprotein(a), or Lp(a), is a type of cholesterol-carrying particle in your blood.5,6 Unlike other cholesterol levels, your Lp(a) level is mostly determined by genetics. That means you inherit it from your family.7 Having high Lp(a) does not mean you will develop heart disease. But it can increase your overall risk.8
Did you know?
About 1 in 5 people have high Lp(a).5 Having high Lp(a) levels is mostly inherited and can increase your risk of an early heart attack or stroke.2,9,10 Most standard cholesterol tests do not include Lp(a) but can be added to your standard blood work.9,11
Heart disease risk can be silent
Learn why high Lp(a) can be hidden – and when to ask your doctor about testing.
How Do Genetics Risk Factors Impact Heart Health?
Did you know?
- Genetics account for 20-30% of your risk for heart disease13
- In the United States, 14% of families account for 72% of all premature heart disease events14
- Children of parents with early heart disease have a 60-75% higher risk of developing heart disease15
High Lp(a) Levels Are Not the End of the Story
High Lp(a) and many other genetic risk factors may not be reduced through lifestyle changes.2,3
The good news? Many other risk factors for heart disease can be managed.
Some risks are linked to daily habits. Others are health conditions that can be treated or controlled.3
Poor diet
Low physical activity
Alcohol use
Smoking
High blood
pressure
High LDL (“bad”) cholesterol
Diabetes
Obesity
Did you know?
Even if you have low Lp(a) levels, heart health still matters. 99% of Americans with heart disease had at least one risk factor before experiencing a heart attack or stroke.17
A Simple Next Step
You can ask:
- What is my overall heart risk?
- Are my blood pressure and cholesterol in a healthy range?
- Should I be tested for Lp(a)?
You may want to ask your doctor about Lp(a) testing if you:
- Have a personal history of early heart disease
- Have a family history of heart disease at a young age
- Have high cholesterol that is hard to control
- Have a family member with elevated Lp(a)
How Does Heart Health Connect to Weight and Sleep?
Your heart health is connected to other parts of your health.
Obesity and obstructive sleep apnea have both been linked to high blood pressure and heart disease.17,18
