While African Americans have slightly lower cholesterol levels than other racial groups, they are more likely to die from heart disease. Socioeconomics, lifestyle, and racism in medicine all play a role.

This article examines the relationship between cholesterol and heart disease in African Americans.
The reported rates of heart disease among Black and African American individuals are slightly higher than in white individuals. However, the death rate is between
This means that Black and African American people have disproportionately higher rates of death from heart disease than their white counterparts.
The following table includes the age-adjusted prevalence of heart disease by percentage of adults in
| Race and ethnicity | Percentage of adults |
|---|---|
| All | 5.5% |
| White, not Hispanic or Latino | 5.5% |
| Black or African American, not Hispanic or Latino | 5.7% |
The following table includes the age-adjusted death rates per 100,000 population for heart diseases in
| Race and ethnicity | Deaths per 100,000 population |
|---|---|
| All | 161.5 |
| White, not Hispanic or Latino | 166.4 |
| Black or African American, not Hispanic or Latino | 208.6 |
There is a lower percentage of Black and African American adults with high total cholesterol than white individuals. The percentage of the population with high total cholesterol between

| White, not Hispanic or Latino | 25% |
| Black or African American, not Hispanic or Latino | 22.2% |
Cholesterol is a waxy, fat-like substance that is in all of the body’s cells. The body makes cholesterol to help produce hormones, vitamin D, and substances that help with food digestion.
Healthcare professionals often refer to high-density lipoprotein (HDL) as “good” cholesterol and low-density lipoprotein as “bad” cholesterol.
Higher HDL levels may help
Conversely, there is an
LDL moves cholesterol around the bloodstream to where the body needs it for cell repair, depositing it in the artery walls. Over time, cholesterol deposits
Narrowed or blocked arteries prevent blood from reaching the heart, brain, and other organs, possibly resulting in heart attack, stroke, or heart failure.
However, even though African Americans are more likely to have lower LDL levels than other groups, they still have higher rates of death from heart disease. This means factors other than cholesterol may increase their risk of adverse heart disease outcomes.
High cholesterol is not the only factor that may raise a person’s risk for heart disease. Additional risk factors for heart disease
- a family history of heart disease
- high blood pressure
- high cholesterol
- diabetes
- tobacco use
- obesity
- a poor diet
- physical inactivity
- alcohol use
Although these risk factors can affect people of all races and ethnicities, some are more prevalent in African Americans.
For example, high blood pressure is more common. The 2017 American College of Cardiology and American Heart Association guidelines state that approximately
Diabetes is also more prevalent. The Office of Minority Health states that African American adults were 60% more likely than non-Hispanic white adults to receive a diabetes diagnosis in 2018 and twice as likely to die from it in 2019.
Additionally, 2023 research found that obesity affects
African Americans may also have certain socioeconomic factors that may affect their heart disease outcomes,
Societal determinants of health, including lower income, less education, and environmental factors,
People with lower incomes are less likely than people with higher incomes to:
- receive diagnostic assessments quickly
- have as much access to medicinal interventions
- receive affordable procedures
- complete cardiac rehabilitation
- have access to quality care
People with a lower education level are more likely to:
- have a higher risk of heart disease and death due to conditions of the heart and blood vessels
- have behavioral and biological risk factors, such as obesity, physical inactivity, and high blood pressure
- have a greater number of conditions alongside heart problems but receive fewer interventions
- not adhere to medications due to cost and accessibility
Certain environmental factors can also have associations with a higher risk of heart disease, such as:
- living in a disadvantaged neighborhood
- neighborhood crime
- poor neighborhood safety, which drives physical inactivity
- insufficient availability of healthy food
- easy access to fast-food restaurants
Among African Americans, there can be significant barriers to accessing healthcare, with
People can take the following steps to help
- Eat a heart-healthy diet with plenty of fruits and vegetables and fewer processed foods.
- Maintain a moderate weight.
- Aim for at least 30–60 minutes of physical activity each day.
- Do not smoke and stay away from secondhand smoke.
- Get regular health screening tests for blood pressure, cholesterol, and diabetes.
- Limit or avoid alcohol intake.
If someone has a condition, such as high blood pressure or diabetes, a doctor may recommend lifestyle changes and prescribe medicines to manage them.
African Americans have a greater risk of adverse outcomes from heart disease than other racial groups.
Although high cholesterol is a significant risk factor for heart disease, it may not explain the disparity in death rates from heart disease among African American people.
Other risk factors for heart disease, such as high blood pressure or diabetes, may contribute. Socioeconomic factors also play a substantial role in creating barriers that prevent African American communities from accessing high quality healthcare.
