Does Heart Disease Run in Your Family?

Have you ever looked at your family history and wondered:

“Why does heart disease seem to affect everyone in my family?”

Maybe your father had a heart attack in his 50s.

Perhaps your mother had a stroke earlier than expected.

Maybe a brother or sister recently needed a stent or was diagnosed with coronary artery disease.

Or perhaps several relatives have been told they have high cholesterol.

Family history can sometimes seem like a collection of unfortunate coincidences.

But sometimes there may be an underlying inherited cardiovascular risk factor contributing to what you are seeing.

One of those factors is Lipoprotein(a), or Lp(a).

Lp(a) is a cholesterol-carrying lipoprotein whose level is largely determined by genetics. Elevated Lp(a) is associated with increased risk of atherosclerotic cardiovascular disease, including heart attack and stroke.

And because high Lp(a) usually produces no symptoms, many people do not discover they have elevated levels until they undergo specific blood testing.

That makes Lp(a) particularly relevant for people who have a strong family history of premature cardiovascular disease.

 

What Is Lipoprotein(a)?

Lipoprotein(a) is a particle that carries cholesterol and other substances through the bloodstream.

It resembles LDL cholesterol but has an additional protein called apolipoprotein(a).

Unlike many cardiovascular risk factors that are strongly influenced by lifestyle, Lp(a) is predominantly genetically determined.

In practical terms, this means your Lp(a) level is largely something you inherit.

You cannot determine your Lp(a) level simply by looking at your diet, body weight, or exercise habits.

You can be physically active.

You can eat a healthy diet.

You can maintain a healthy weight.

You can have normal blood pressure.

And you can still have elevated Lp(a).

This is one reason why Lp(a) can be important when evaluating people who appear healthy but have a concerning family history.

 

Why Is Family History So Important?

Family history can provide clues about inherited cardiovascular risk.

Suppose your father had a heart attack at 48.

That does not automatically mean you will have a heart attack at 48.

However, it may indicate that you and other family members could share genetic factors that increase cardiovascular risk.

Lp(a) is one possibility.

Other inherited conditions can also influence cardiovascular risk, including familial hypercholesterolemia, a genetic condition associated with high LDL cholesterol.

The important point is that family history should not be ignored simply because your current cholesterol test looks acceptable.

A standard cholesterol panel does not normally measure Lp(a).

Therefore, someone can have:

Normal-looking cholesterol + elevated Lp(a) + significant family history.

Without an Lp(a) test, that additional risk factor may remain unknown.

 

What Counts as a Concerning Family History?

There is no single family-history pattern that guarantees you have inherited cardiovascular disease.

However, certain situations deserve a closer conversation with a healthcare professional.

These may include:

• A parent who experienced a heart attack at a relatively young age
• A brother or sister with premature coronary artery disease
• Multiple close relatives with heart attacks
• Multiple relatives with strokes at younger ages
• Relatives requiring coronary stents or bypass surgery earlier than expected
• A family history of familial hypercholesterolemia
• Cardiovascular disease occurring despite apparently favorable traditional risk factors
• Sudden or unexplained cardiovascular events in close relatives

If several of these circumstances apply to you, it may be worthwhile to discuss inherited cardiovascular risk with your doctor.

 

What Age Is Considered “Young” for a Heart Attack?

You may hear physicians use terms such as premature cardiovascular disease or premature coronary artery disease.

These terms generally refer to cardiovascular disease occurring earlier than expected, although the precise age thresholds can vary depending on the guideline and clinical context.

The important message for patients is simple:

A heart attack at a relatively young age in a close family member deserves attention.

If your father, mother, brother, or sister developed coronary artery disease much earlier than expected, tell your physician.

That information can influence how your own cardiovascular risk is evaluated.

 

Could High Lp(a) Explain Heart Disease in My Family?

It is possible.

But an Lp(a) test cannot prove that elevated Lp(a) is the sole reason cardiovascular disease occurred in your family.

Heart disease is usually multifactorial.

Genetics, LDL cholesterol, blood pressure, diabetes, smoking, age, lifestyle, and many other factors can interact.

However, an elevated Lp(a) level can provide an important additional piece of information.

For example:

A 45-year-old woman may have a healthy weight, exercise regularly, never smoke, and have an LDL cholesterol level that does not initially appear alarming.

Her father had a heart attack at 51.

Her older brother had coronary artery disease at 49.

She may reasonably ask:

“Is there something inherited that I should know about?”

An Lp(a) test is one way to investigate that question.

 

Does High Lp(a) Cause Symptoms?

Usually, no.

This is perhaps the most important thing to understand.

Elevated Lp(a) generally does not cause a person to feel:

• Tired
• Dizzy
• Short of breath
• Aware of their heartbeat
• Chest pain specifically because of the Lp(a) level
• Headaches

There is no reliable symptom that tells you:

“My Lp(a) is high today.”

The only way to know your Lp(a) level is to have it measured.

This is why people with a strong family history should not rely solely on how they feel.

You can feel perfectly healthy and still have an inherited cardiovascular risk factor.

If you are experiencing chest pain, pressure, shortness of breath, fainting, sudden weakness, or other concerning symptoms, those symptoms should be medically assessed rather than assumed to be related to Lp(a).

 

Can You Have High Lp(a) With Normal Cholesterol?

Yes.

This is a major reason Lp(a) testing can be valuable.

Your regular cholesterol test may report:

• Total cholesterol
• LDL cholesterol
• HDL cholesterol
• Triglycerides

Lp(a) is generally not included in the standard lipid panel.

Therefore, your doctor cannot determine your Lp(a) level simply by looking at your LDL cholesterol.

Someone can have a relatively favorable LDL cholesterol result while having elevated Lp(a).

This does not mean LDL cholesterol is unimportant.

In fact, if Lp(a) is elevated, controlling LDL cholesterol and other modifiable risk factors can become especially important.

 

Who Should Have an Lp(a) Test?

Current guidelines have increasingly moved toward broader Lp(a) screening.

The 2026 ACC/AHA guideline on the management of dyslipidemia recommends measuring Lp(a) at least once in adulthood.

Testing can be particularly relevant for people with:

A Strong Family History

If cardiovascular disease occurs repeatedly in your immediate family, Lp(a) may be worth discussing.

Premature Cardiovascular Disease

If a close relative had a heart attack, stroke, or coronary artery disease at a relatively young age, mention it to your doctor.

Familial Hypercholesterolemia

If your family has a history of genetically high LDL cholesterol, Lp(a) may provide additional information.

Your Own Cardiovascular Disease

People who have already experienced cardiovascular disease may benefit from understanding whether elevated Lp(a) is contributing to their overall risk profile.

Unexplained Cardiovascular Risk

If cardiovascular disease appears disproportionate to your traditional risk factors, an Lp(a) test may provide another piece of information.

 

Is Lp(a) Testing a One-Time Blood Test?

For many adults, yes.

Because Lp(a) is largely genetically determined and relatively stable, a single measurement can provide useful lifelong information.

However, your healthcare professional may decide that repeat testing is appropriate in certain circumstances.

The exact approach depends on the individual’s clinical situation, laboratory testing, and treatment plan.

The important point is that you generally do not need to monitor Lp(a) in the same way that you might monitor blood pressure or blood glucose every few weeks.

 

What Happens If My Lp(a) Is Elevated?

First, don’t panic.

An elevated Lp(a) result does not mean that you have a blocked artery.

It does not mean that a heart attack is inevitable.

It does not mean that your children will necessarily develop heart disease.

Instead, it means that you have identified a cardiovascular risk factor that should be considered alongside everything else.

Your cardiologist may review:

• LDL cholesterol
• ApoB
• Non-HDL cholesterol
• Blood pressure
• Blood glucose
• Diabetes risk
• Smoking
• Weight
• Physical activity
• Family history
• Previous cardiovascular disease
• Age and other risk factors

The treatment strategy is usually about reducing total cardiovascular risk.

 

Can I Lower Lp(a) With Diet and Exercise?

This is a very common question.

The answer is somewhat different from what you might expect.

Because Lp(a) is predominantly genetically determined, lifestyle changes generally have limited effects on the actual Lp(a) concentration.

But that does not make lifestyle changes unimportant.

In fact, if you have elevated Lp(a), managing your other cardiovascular risk factors may become even more important.

That includes:

Exercise

Regular physical activity supports heart health, fitness, blood pressure, and metabolic health.

Healthy Eating

A heart-healthy dietary pattern can help manage LDL cholesterol, blood pressure, blood sugar, and weight.

No Smoking

Smoking substantially increases cardiovascular risk and should be avoided.

Healthy Weight

Maintaining a healthy weight can improve multiple cardiovascular risk factors.

Blood Pressure Management

High blood pressure can independently increase cardiovascular risk.

Diabetes Management

Elevated blood glucose and diabetes can add to cardiovascular risk.

You may not be able to change the genes that determine your Lp(a).

But you can often change many of the other factors that influence your overall cardiovascular health.

 

Should My Family Members Get Tested?

Possibly.

Because Lp(a) is inherited, an elevated result can raise the question of whether close relatives should also be tested.

This is particularly relevant when multiple members of a family have experienced premature cardiovascular disease.

If you discover that your Lp(a) is elevated, ask your physician:

“Should my brothers, sisters, parents, or adult children have their Lp(a) checked?”

Your doctor can help determine who may benefit from testing based on age, family history, and individual circumstances.

This approach can potentially identify inherited cardiovascular risk in family members who otherwise feel completely healthy.

 

What If My Parent Had a Heart Attack but My Lp(a) Is Normal?

A normal Lp(a) result is reassuring regarding that particular inherited risk factor, but it does not eliminate all inherited cardiovascular risk.

Your family history still matters.

Heart disease can result from many interacting genetic and environmental factors.

Your physician may therefore consider:

• LDL cholesterol
• ApoB
• Blood pressure
• Blood sugar
• Smoking
• Weight
• Lifestyle
• Other family history
• Other inherited conditions

Think of Lp(a) as one piece of the cardiovascular puzzle.

A normal Lp(a) result does not erase your family history.

 

What If My Lp(a) Is High and My Parent Also Had a Heart Attack?

This combination deserves a more detailed cardiovascular risk discussion.

For example, imagine:

• Your mother had a heart attack at 52.
• Your Lp(a) is elevated.
• Your LDL cholesterol is borderline.
• Your blood pressure is occasionally high.

None of these facts alone tells the entire story.

Together, however, they provide a stronger reason to have your cardiovascular risk carefully assessed.

The goal is to identify the factors that can be changed and determine whether additional prevention strategies are appropriate.

 

What Should I Bring to a Lipid Clinic Appointment?

If you are seeing a cardiologist about Lp(a), bring as much relevant information as possible.

This may include:

• Your latest cholesterol results
• Previous cholesterol results
• Your Lp(a) result and units
• Blood pressure readings
• Medication list
• Diabetes or blood sugar results
• Smoking history
• Previous heart tests
• Previous cardiovascular diagnoses
• Family history of heart attack and stroke

If possible, find out:

Who in your family had cardiovascular disease, what happened, and approximately how old they were.

That information can be surprisingly valuable.

 

Why See a Cardiologist for High Lp(a)?

An elevated Lp(a) number should not be interpreted in isolation.

A cardiologist with experience in lipid management can help determine what the result means in the context of your:

• Age
• Family history
• LDL cholesterol
• ApoB
• Blood pressure
• Diabetes status
• Previous cardiovascular history
• Lifestyle
• Other risk factors

The goal is to move beyond simply saying:

“Your Lp(a) is high.”

The more useful question is:

“What does this mean for your overall cardiovascular risk, and what can we do about the risks that can be modified?”

 

Lipoprotein(a) and Family Heart Risk in Brampton, Mississauga & Milton

If you live in Brampton, Mississauga, Milton, or surrounding Ontario communities, you may already be monitoring your cholesterol or blood pressure.

But if heart disease seems to run in your family, it may be worth asking whether inherited lipid factors such as Lp(a) have been evaluated.

You do not need to wait until you experience chest pain or another cardiovascular event to discuss prevention.

In fact, the absence of symptoms is one of the reasons preventive cardiovascular care is so important.

A person with elevated Lp(a) may feel completely normal.

A person with a significant family history may feel completely normal.

That is precisely why identifying risk factors before an event occurs can be valuable.

 

Questions to Ask Your Cardiologist

If heart disease runs in your family, consider asking:

“Have I ever had my Lp(a) measured?”

“Is my family history concerning for premature cardiovascular disease?”

“What does my Lp(a) result mean?”

“What is my LDL cholesterol goal?”

“Should I have ApoB tested?”

“Should my close relatives have Lp(a) testing?”

“Are there other cardiovascular risk factors we should address?”

“Do I need additional cardiac testing?”

These questions can help turn a family history into an actionable prevention plan.

 

Conclusion

If heart disease runs in your family, you may have wondered whether genetics are playing a role in your own cardiovascular risk.

Lipoprotein(a), or Lp(a), is one inherited factor that can contribute to cardiovascular risk.

The challenge is that high Lp(a) usually causes no symptoms.

You cannot determine whether your Lp(a) is elevated by how you feel.

You may exercise regularly, eat well, maintain a healthy weight, and still have a genetically elevated Lp(a).

That is why knowing your family history and discussing Lp(a) testing with your healthcare provider can be important.

Current cardiovascular guidance recommends measuring Lp(a) at least once in adulthood. If your result is elevated, it does not mean that a heart attack is inevitable. Instead, it provides an opportunity to take a closer look at your complete cardiovascular risk profile.

Your genetics are not something you can change.

But LDL cholesterol, blood pressure, blood sugar, smoking, physical activity, diet, and many other cardiovascular risk factors can often be addressed.

If you have a strong family history of heart attacks or strokes, an elevated Lp(a), high cholesterol, or unexplained cardiovascular risk, consider speaking with a cardiologist experienced in lipid management.

For patients in Brampton, Mississauga, Milton, and surrounding areas, Dr. Sunny Malhotra provides cardiology and advanced lipid management services focused on understanding and reducing cardiovascular risk.

 

Frequently Asked Questions

1. If heart disease runs in my family, should I get an Lp(a) test?

It may be appropriate. A strong family history of premature cardiovascular disease is an important reason to discuss Lp(a) testing with your physician. Current guidelines also recommend at least one Lp(a) measurement during adulthood.

2. Can Lp(a) explain why my family has heart disease?

It may be one contributing factor. However, cardiovascular disease is usually caused by multiple genetic and environmental factors. An elevated Lp(a) result does not prove that it caused cardiovascular disease in your family.

3. Is high Lp(a) inherited?

Yes. Lp(a) levels are largely genetically determined.

4. If my Lp(a) is high, will I have a heart attack?

No. An elevated Lp(a) level increases cardiovascular risk, but it does not mean that a heart attack is inevitable.

5. Can I have high Lp(a) even if my cholesterol is normal?

Yes. Lp(a) is a separate measurement and is generally not included in a standard cholesterol panel.

6. Does high Lp(a) cause chest pain?

Usually not. Elevated Lp(a) generally does not cause symptoms. Chest pain should be evaluated based on the symptom itself rather than attributed to Lp(a).

7. Should my children be tested if my Lp(a) is high?

Because Lp(a) is inherited, family testing may be appropriate in some circumstances. Discuss the appropriate timing and approach with your healthcare professional.

8. Can exercise lower my Lp(a)?

Exercise generally has limited effects on the Lp(a) number itself, but it is extremely important for reducing overall cardiovascular risk.

9. Can a healthy diet eliminate high Lp(a)?

No. Diet generally has little effect on genetically determined Lp(a). However, a heart-healthy diet remains important for controlling other cardiovascular risk factors.

10. What should I do if my Lp(a) is high?

Discuss the result with your healthcare professional. Your overall cardiovascular risk should be assessed, including LDL cholesterol, blood pressure, diabetes, smoking, family history, and other relevant factors.
