Know Your Heart Disease Risk
Some heart disease risk factors are within your control. Others aren't.
Understanding both can help you make better decisions about protecting your heart.
Heart disease usually doesn't come down to one single risk factor.
Your blood pressure matters. So do your cholesterol, blood sugar, tobacco exposure, activity level, family history, age, and other factors.
And these risks don't exist in isolation.
Someone with high blood pressure and diabetes and high cholesterol may have a very different cardiovascular risk than someone with only one of those factors.
That's why knowing an individual number isn't enough.
Heart disease risk is about the whole picture—not one lab result, one habit, or one number on the scale.

Not All Risk Factors Are the Same
There are heart disease risk factors you can change or manage and others you cannot change.
Understanding the difference isn't about blame.
It's about knowing where your attention can make a difference.
RISKS YOU CAN CHANGE OR MANAGE
Blood pressure
Cholesterol
Diabetes and blood sugar
Tobacco exposure
Physical activity
Nutrition
Weight, when relevant
RISKS YOU CAN'T CHANGE
Age
Family history
Genetics
Biological sex
Certain inherited conditions
You can't change every risk factor. But you can understand your overall risk and work on the factors that are modifiable.

How Do These Risk Factors Affect Your Heart?
Knowing that something is a “risk factor” isn't very helpful if you don't understand why.
Each of these factors can affect your cardiovascular system differently—and several occurring together can increase your overall risk.
HIGH BLOOD PRESSURE
More Pressure. More Work.
Over time, high blood pressure can damage artery walls and make the heart work harder to pump blood.
That extra workload can contribute to changes in the heart muscle and increase the risk of problems such as heart attack, heart failure, stroke, and kidney disease.
High blood pressure often doesn't cause symptoms. That's why knowing your numbers matters.
HIGH CHOLESTEROL
Plaque Can Build Quietly.
Your body needs cholesterol, but elevated levels of certain cholesterol-containing particles—particularly LDL—can contribute to plaque buildup inside artery walls.
As plaque accumulates, arteries can become narrowed. If a plaque ruptures and a blood clot forms, blood flow can suddenly become blocked.
In a coronary artery, that can cause a heart attack.
You can't tell what your cholesterol is by how you feel. You have to measure it.
DIABETES & HIGH BLOOD SUGAR
The Cardiovascular Connection Matters.
Over time, diabetes can damage blood vessels and is associated with a higher risk of cardiovascular disease.
Diabetes also frequently occurs alongside other cardiovascular risk factors, including high blood pressure and abnormal cholesterol levels.
Managing diabetes isn't only about blood sugar. It's also about protecting your heart, kidneys, eyes, nerves, and blood vessels.
TOBACCO EXPOSURE
Your Heart and Blood Vessels Feel the Effects.
Smoking damages blood vessels, promotes inflammation and clot formation, and increases cardiovascular risk.
And this isn't only about cigarettes. Exposure to secondhand tobacco smoke also increases cardiovascular risk.
Stopping tobacco use is one of the most important modifiable steps a person who smokes can take for cardiovascular health.
PHYSICAL INACTIVITY
Your Cardiovascular System Was Designed to Move.
Regular physical activity supports heart and blood-vessel health and can help improve blood pressure, cholesterol, blood sugar, fitness, sleep, and weight management.
You don't have to become an athlete.
Movement counts—and starting somewhere is more useful than waiting for the perfect exercise plan.
NUTRITION
Patterns Matter More Than Perfection.
What you eat over time can influence blood pressure, cholesterol, blood sugar, and body weight.
Rather than labeling individual foods as simply “good” or “bad,” focus on the overall pattern: more vegetables and fruits, whole grains, legumes, nuts, appropriate protein sources and unsaturated fats, while limiting excess sodium, added sugars and highly processed foods.
Heart-healthy eating is a pattern—not a punishment.
WEIGHT
Important—But Not the Whole Story.
Excess body weight can be associated with higher risk of high blood pressure, diabetes, abnormal cholesterol, sleep apnea, and cardiovascular disease.
But weight alone does not define someone's health or cardiovascular risk.
That's why the larger picture matters—including blood pressure, laboratory results, medical conditions, physical activity, sleep, family history, and other factors.
The number on the scale is one piece of information—not your entire health story.
Risk Factors Can Travel Together
Consider three people:
PERSON A
High blood pressure
PERSON B
High blood pressure + high LDL cholesterol
PERSON C
High blood pressure + high LDL cholesterol + diabetes + smoking
Their cardiovascular risk isn't necessarily the same simply because all three have high blood pressure.
Your individual risk comes from the combination of your risk factors—not from looking at any one factor alone.
What Does Your Heart Disease Risk Actually Mean?
Your Risk Is an Estimate—Not a Prediction
When healthcare professionals assess cardiovascular risk, they don't look at just one number.
They may consider several factors together, such as your:
Age • Blood Pressure • Cholesterol • Diabetes Status • Smoking History • Kidney Health • Medication Use
These pieces can be combined to estimate the likelihood of developing cardiovascular disease over a certain period of time.
But here's the important part:
A risk estimate doesn't predict exactly what will happen to you. It helps guide decisions about prevention.
If an estimate shows increased cardiovascular risk, it doesn't mean that person is destined to have a heart attack or stroke.
It means there may be opportunities to lower that risk.
Why Calculate Risk at All?
Because prevention decisions should be individualized.
Understanding your cardiovascular risk can help you and your healthcare professional have better conversations about questions such as:
How aggressively should we manage my blood pressure?
Would I benefit from cholesterol-lowering medication?
Which lifestyle changes could have the greatest impact for me?
Are there additional tests that might help clarify my risk?
The goal isn't to give you another number to worry about.
The goal is to use information to make better decisions.
Sometimes We Need More Information
For some people, the best prevention decision isn't obvious after looking at traditional risk factors.
A healthcare professional may consider additional information, such as family history or other risk-enhancing factors.
For certain people, additional testing—such as a coronary artery calcium (CAC) scan—may also help refine cardiovascular risk and guide preventive decisions.
More testing isn't automatically better. The right test is one that can meaningfully change what you and your healthcare professional do next.
One Number Doesn't Tell Your Whole Story
Your cardiovascular risk can change.
Blood pressure can improve.
Cholesterol can be treated.
Diabetes can be managed.
Tobacco use can stop.
Physical activity can increase.
And preventive medications may lower risk when they're appropriate.
You can't change your age, genetics, or family history—but those factors can help determine how much attention the modifiable factors deserve.
Know your risk—not so you can fear the future, but so you can make informed decisions about it.
How Well Do You Know Your Heart Health?
You don't need to know every medical term or memorize every lab value.
But there are some basic pieces of your health information worth knowing.
Your Heart Health Check-In
Do you know your blood pressure?
Do you know your cholesterol numbers—especially your LDL cholesterol?
Do you know your blood sugar or A1C if you've been tested?
Do you know whether heart disease or stroke runs in your family—and at what age it occurred?
Do you use tobacco or regularly breathe secondhand smoke?
Are you getting regular physical activity?
Do you know whether you have other conditions that may affect cardiovascular risk, such as kidney disease or diabetes?
You can't manage information you don't have. Start by knowing your numbers, your history, and your habits.
If you don't know some of these answers, your next routine healthcare visit is an opportunity to find out.
Consider asking:
“Can we talk about my overall risk for heart disease and what I should be working on?”
Your Risk Is Not Your Destiny
Learning that you have risk factors for heart disease can feel concerning.
But identifying risk isn't about predicting that something bad will happen.
It's about recognizing where prevention may make a difference.
Some risk factors can't be changed. You can't change your age, genetics, or family history.
But many important factors can be treated, managed, or improved.
Blood pressure can be treated.
High cholesterol can be addressed.
Diabetes can be managed.
Tobacco use can stop.
Physical activity can increase.
Nutrition patterns can change.
And when medication is appropriate, it can be another important tool for reducing cardiovascular risk.
You don't have to eliminate every risk factor to make meaningful progress.
Prevention Is About the Whole Picture
Protecting your heart isn't about chasing one perfect blood pressure, cholesterol value, weight, diet, or exercise routine.
It's about understanding your combination of risks and deciding which changes are likely to matter most.
For one person, that may mean getting blood pressure under control.
For another, it may mean treating high cholesterol.
For someone else, stopping smoking may have the greatest impact.
And for many people, several smaller changes work together.
Know where you are. Understand what you can change. Then work with your healthcare team on what matters most.
