Hereditary Heart Conditions

More than 1 in 60 people have an inherited cardiovascular condition

What is an Inherited Heart Condition?

There are many different conditions of the heart. Some are more likely to run in families. Inherited heart conditions are caused by a change or mutation in one gene or in a number of genes.

Types of inherited heart conditions include cardiomyopathies, arrhythmias, thoracic aortic aneurysms and dissections, and familial hypercholesterolemia. One of the most important reasons for identifying your risk early for a hereditary heart condition is because many of these conditions are often asymptomatic, and sudden death can be the first and only symptom.

autosomal dominant cardiovascular condition

There is a 50% chance of inheriting an autosomal dominant cardiovascular condition from an affected first-degree relative

Recognize the Symptoms of an Inherited Cardiovascular Condition

Most inherited heart conditions are passed down in an autosomal dominant chromosome pattern and often show up in multiple generations in a family. These conditions can also be associated with death at a young age due to sudden cardiac arrest or aortic dissection. Knowing whether you or a loved one are at an increased risk for one of these disorders can help make sure that proper medical care is administered to prevent any serious events.

inherited cardiovascular disorders

Symptoms vary from person to person, but inherited cardiovascular disorders can cause:
Shortness of Breath | Fatigue Chest Pain | Irregular Heartbeat | Fainting | Coughing | Nausea even Sudden Death in rare cases.

How Genetic Testing May Help

impact of genetic testing

Confirm or rule out a suspected inherited heart condition or help determine your chance of developing or passing it on.

impact of genetic testing

Confirm a diagnosis, particularly when clinical criteria are unclear or borderline

impact of genetic testing

Choose a better medicine or other treatment method

impact of genetic testing

Identify an inherited mutation following a sudden unexplained death with autopsy findings

impact of genetic testing

Clarify risks to family members, including the inheritance pattern

impact of genetic testing

Reduce future healthcare costs, resources, and anxiety for families

How Genetic Testing May Help Your Family

WHAT HAPPENS IF I TEST POSITIVE FOR A GENE MUTATION?

There is a 50/50 chance that each of your children, brothers, sisters, and parents also has this same mutation.

Your family members can now be tested for this mutation. Any family members who also carry the mutation are at increased risk to develop the cardiovascular condition and should consult a cardiologist.

Cancer gene pedigree

Any family members who test negative for this mutation are likely not at increased risk for the cardiovascular condition.

Am I a Candidate for Genetic Testing?

IF YOU ANSWER “YES” TO ANY OF THE QUESTIONS BELOW, HEREDITARY CARDIOVASCULAR GENETIC TESTING MAY BE SOMETHING FOR YOU AND/OR YOUR FAMILY MEMBERS TO CONSIDER.

Have you/your family members* been diagnosed with any inherited heart condition/disorder?

Have you/your family members* been diagnosed with high cholesterol?

Is there any history of a sudden unexpected death or cardiac arrest in your family?

Does anybody in your family have a pacemaker or implantable cardioverter defibrillator (ICD) device?

Is there a personal or family history of unexplained fainting or passing out?

If your responses indicate that you may be at-risk for a hereditary cardiovascular condition, there’s no need to panic.

Not everyone who has a risk will necessarily go on to develop disease. Genetic test results are a tool to help clarify your risk for cardiovascular conditions, and inform your healthcare provider in determining the best plan of action moving forward.

*Your healthcare provider may identify other reasons why it may be beneficial for you to consider genetic testing

Am I a candidate for Genetic Testing

What Test Results Can I Expect? And What Do I Do Once I Have Them?

POSITIVE, NEGATIVE, OR A VARIANT OF UNKNOWN SIGNIFICANCE (VUS)

Results from your genetic tests will fall into one of three categories:

A mutation related to a hereditary cardiovascular condition has been found in at least one of your tested genes:

A mutation was found in at least one of the genes tested.

There may be management recommendations specific to the gene that has a mutation.

Genetic testing for certain family members may be recommended.

No cardiovascular disease-related genetic mutations were found in any of your tested genes

Since inherited disease risk(s) and management recommendations are based on personal and family history as well as genetics, you may still want to discuss next steps with your healthcare provider.

Despite your negative result, genetic testing may be advisable for family members if they have been diagnosed with or are showing symptoms of cardiovascular disease.

At least one genetic mutation was found, but it is unclear if this change causes an increased risk for an inherited cardiovascular disease

Consult with your healthcare provider on if genetic testing should be considered for your family members. Recommendations vary based on personal and family history

These results may change over time as we learn more information and you could possibly get an updated result in the future
